When it comes to Public Square, where have all the bollards gone?

If you look closely, you will see retractable bollards on Superior, running parallel to West and East Roadways in this rendering from Field Operations (courtesy of Cleveland.com).

Last week, Mayor Frank Jackson and Chief of Police Calvin Williams sent separate letters to the Secretary of Transportation Anthony Foxx and Federal Transit Administration acting head Carolyn Flowers, respectively, in which they asked the two agencies to extend the deadline for GCRTA to pay the $12 million fine for closing the Public Square bus lanes.

Both letters emphasized the city’s safety concerns, particularly the threat that someone may use the 600-foot stretch of Superior Avenue to drive a large truck into a crowd of people, as we saw unfold in the tragic attacks in Nice and Berlin.

Chief Williams’ letter, in particular, echoed earlier statements from Public Safety Director Michael McGrath:

Of particular concern is the recent and continued use of motor vehicles by terrorists to attack citizens attending public events. Ohio is one of a few states to receive particular attention by federal authorities in the past few months. Opening Public Square to cross traffic allows a determined individual to gain speed traveling on Superior Avenue and divert directly into a crowd gathered on the square.

The threat of terrorism should always be accounted for, as it is an all too common reality in today’s world. But, while Mayor Jackson and his public safety officials keep hyping it time and time again as a justification for closing the Square, they have failed to even discuss alternative options to – say it with me – mitigate this risk.

Let’s ignore, for a minute, whether or not GCRTA or the FTA has any regulatory obligation to address this question, as Mayor Jackson keeps insisting, and take him at his word.

I’ve met the Mayor on a few occasions, and I’ve always found him to be a polite man who is generous with his time and seems to legitimately care about the people he is supposed to serve. So I am willing to believe that he honestly worries about the safety risks. That said, why does he appear so ardently opposed to considering other options, short of closing the Square entirely?

The threat from vehicles is not new

As Chief Williams noted in his letter, there is “particularly concern” stemming from “the recent and continued use of motor vehicles by terrorists.”

But we should not be ahistorical and pretend that this trend is somehow new. Quite the opposite. Terrorists have been using vehicles as weapons for decades now, stemming back at least to the bombing of the World Trade Center in 1993.

In response, cities around the world have installed barriers to prevent individuals from getting their vehicles close enough to buildings to cause the type of devastation we witnessed in this attack. As New York University professor Marita Sturken described in her book Tourists of History: Memory, Kitsch, and Consumerism from Oklahoma City to Ground Zero:

The 1993 World Trade Center bombing and the 1995 Oklahoma City bombing both had high destructive impact because trucks were able to get into or next to the buildings. This has produced and industry in the construction of such devices as bollards and NoGos. Steel or concrete bollards, which now surround the vast majority of government buildings, are designed to stop a truck going fifty miles an hour. Sleek bollards are a now a key feature of security design…While Washington, D.C., has been the site of the most obvious barriers for federal buildings, there are now many projects to situate bollards around tourist sites such as the Washington Mall in ways that are less intrusive and more aesthetically pleasing.

So why did the City of Cleveland and its partners in the Public Square redesign not include concrete bollards, NoGos, or some other form of vehicle barrier along the curbs on Superior Avenue to – you guessed it – mitigate these terrorism concerns?

Vehicle barriers already exist in Cleveland

It’s not as though, like contemporary fashion, these design features have stayed on the East Coast and not yet filtered over to Cleveland yet. On the contrary, we already have bollards, barriers, and planters installed outside of buildings throughout downtown, including City Hall, the Federal Reserve Bank, the Federal Building, and Key Tower, which sits just steps from the newly redesigned Square. We already had the foresight to install them at other sensitive locations, so why not Public Square?


Moreover, we have already installed bollards curbside along other public green spaces in Cleveland! East and West Mall Drives run parallel to Mall B downtown. As you can see below, in order to lower the risk that a car could jump the curb from those streets and crash into a gathering on the Mall, officials installed bollards. We’re already doing this.

bollards west mall drive

Bollards, both permanent and removable, abut West Mall Drive, protecting Mall B from vehicles.

We need to talk about the Malls

But, unlike Public Square, not every public green space in downtown Cleveland has raised the same breathless specter of terrorism. Venture just across the street south to Mall A, and you can see that the bollards disappear. The same thing happens when you head north to Mall C. Hell, even if you just go around the corner on Mall B, there are no bollards abutting St. Clair.


Each of the Malls runs along wide avenues – St. Clair and Lakeside – that can hold high volumes of traffic moving at high speeds. Each of them includes curb cuts that could allow someone to drive up off the street without being slowed down.

These Malls have been the sites of many large public gatherings, from protests to yoga classes to art installations to the Gay Games Festival Village and the Cleveland Orchestra’s Fourth of July concert. Where was the administration raising terrorism concerns when they were redesigned on the public dime, also to much fanfare? What makes Public Square so uniquely vulnerable?

I understand that the Square has a street bifurcating it, but similar conditions exist just a stone’s throw away.

What happened to the retractable bollards?

More galling, the original design of the Square, which starchitect James Corner unveiled in 2014, actually included retractable bollards at the intersections of Superior and East and West Roadways, which could be raised to close the street for special events. The City and its partners included these bollards in the plan, but scrapped them somewhere along the way.

Whose call was this? What was the justification?

So what’s really going on here?

Even if you take the administration at their word and assume their motives are pure, their arguments don’t hold up to scrutiny. This raises the question – what is their actual motivation?

Is it the Mayor’s assertion that the City was shocked by how popular the new space was? Are we honestly supposed to believe that the City spent tens of millions of dollars on a new Public Square, under the assumption that a few dozen people would maybe use it sometimes?

Or could it be, as Councilman Zack Reed suggested and Chief of Staff Ken Silliman perhaps accidentally admitted on November 30, that the businesses in and around the Square (including those who helped fund its completion) don’t want “those people” hanging around, waiting for the bus? If this is your real motivation, I urge you to reconsider.

Ultimately, each of these arguments falls apart when you actually hold it under the microscope.

We never should have gotten to this point, where GCRTA is facing a potentially crippling fine. Our elected and appointed officials should be able to demonstrate even a modicum of foresight and planning on issues such as this.

Public Square is an outstanding public space, and everyone should be able to utilize it. But, despite its many excellent features that make it unique in Cleveland, it is not uniquely vulnerable to terrorist attacks.

If you want to mitigate this risk, by all means do so. But that does not require closing the Square to buses.

Open Public Square to buses, because bus riders deserve nice things, too


Unless you’ve been living under a rock or don’t pay attention to debates about public transit and green space in Cleveland (so, 99.9999% of the world), you probably know that the other shoe dropped in the Public Square bus lane debate late last month, when the Federal Transit Administration sent a Notice of Debt to GCRTA for $12 million in funds for the Euclid Corridor/HealthLine bus rapid transit (BRT) project.

This debate has now really come to a head, as FTA provided just 30 days (starting December 20) for GCRTA to pay the full fine or file a formal dispute.

To this point, the fight over the Public Square bus lanes has taken on a number of forms. There was was Mayor Frank Jackson’s claim that the Square was more popular than they anticipated and his fiery assertions that FTA is using the fine to distract from its legal obligations to ameliorate the City’s continued claims of terrorist threats (of course, as Sam Allard has reported, it appears the Mayor completely made these up, but YOLO I guess).

There were those noted the logistical and financial hardship placed on GCRTA from having to drive around the Square, while others have raised the safety risks inherent in forcing bus drivers to take more than 1.1 million additional turns. Tragically, we saw those risks unfold on December 7. Still others made unnecessarily esoteric arguments about marginal emissions due to the decision; seriously, what nerd did that?

Moving beyond the numbers to the people in this debate

But, for the most part, the parties waging this policy battle have not gone into detail on the impacts of dispersing riders who would otherwise transfer or catch their buses in the Square to outlying bus stops. There are two main exceptions to this. The first was Councilman Zack Reed’s – shall we say – entertaining descent into the Cleveland.com comments section during the November 30 City Council Transportation Committee hearing. The second was a story from WEWS, which relayed safety concerns from riders about being displaced from the bus stops on the Square to others which were poorly lit and located.

It’s to this issue that I want to turn now, in light of a recent study (paywall) from the Transportation Research Board, which focuses on how the physical environment can affect people’s perceptions of bus waiting times.

In their introduction, authors Marina Lagune-Reutler, Andrew Guthrie, Yingling Fan, and David Levinson (herein Lagune-Reutler et al) point out that the amount of time transit users spend waiting to ride is vital for shaping people’s perceptions of public transit. Research event suggests that time and service quality are more important for influencing people’s transportation mode choice than financial costs. Accordingly, if a transit agency makes efforts to cut waiting times, or even the perception of waiting times, they can enhance their public standing and potentially increase ridership without undertaking major capital investments.

A wide array of previous research demonstrates that several variables can influence how long people feel they have waited for their bus or train to arrive. A 1993 study from global consulting behemoth Parsons Brinckerhoff – which, coincidentally, GCRTA is paying $60,000 to conduct a study to find alternatives to opening Public Square – in the Twin Cities showed that access to clear, reliable information on waiting times affects riders’ sense of time. According to the study, a lack of reliable service and unpredictable delays can increase the perceived amount of time spent waiting among transit users. Given that GCRTA has continued to cut service, and CEO Joe Calabrese has reported that 43% of buses that transit Public Square are delayed due to the closure, this issue clearly affects bus riders.

A separate 2016 study (paywall) from Fan, Guthrie, and Levinson found that women, in particular, report perceiving longer waiting times at transit stops and stations located in unsafe environments. “At a simple curbside bus stop, a 10-min wait seems to take nearly a half hour.”

In contrast, a 2014 study conducted in Naples, Italy (paywall) by Ennio Cascetta and Armando Cartenì reported that high-quality waiting environments can not only reduce perceived waiting times, they can actually provide “hedonic value” – a sense of pleasure or happiness – among riders, especially women. This research again applies to the case at hand, as women constitute a majority of GCRTA riders, overall, and they account for even larger shares of bus and BRT riders.

Capturing the impacts of the transit waiting environment

Lagune-Reutler et al build upon this earlier work to examine how transit waiting environments influenced perceived waiting times at 36 stations in the Twin Cities. The stops were classified according to several variables, including: type (transitway station, transit center, improved curbside stop, or unimproved curbside stop); location (residential or commercial, urban or suburban); and a pleasantness score (low, medium, or high). They analyzed the influence of a number of independent variables, using measures of traffic safety and neighborhood security like posted speed limits, traffic volume, sidewalk characteristics, streetlights, vacant properties, noise and air pollution levels, and tree cover.

The authors conducted surveys from 822 transit users to capture the amount of time they felt they spent waiting for the bus or train during July-August 2013 and February-April 2014. They then compared these self-reported times to video footage, which provided actual waiting time for these same participants.

The waiting is the hardest part

Their results showed that, on average, transit users tended to overestimate their waiting times by roughly 18%, stating they felt they waited for a mean of 6.45 minutes, when the actual value was 5.48 minutes. Air pollution and heavy traffic combined to cause riders to significantly overestimate their waiting times. A 2.5-minute wait was seen as 3.88 minutes, while a 10-minute wait grew to 12.13.

Tree cover, in turn, can alleviate this effect, particularly for longer waits. Riders perceived their 10-minute waits as lasting just 7 minutes when surrounded by mature trees. According to the authors,

Generally, the results suggest that the more trees present, the shorter the wait time is perceived by riders, whereas the more polluted and exposed to traffic, the more transit users tend to overestimate wait time. These findings advocate for high-quality urban environments surrounding stops and stations.

This finding provides an important point that has largely been ignored in the Public Square debate to this point. It’s not simply a matter of whether closing the Square to buses will cost more or whether a unified square is more aesthetically appealing. What matters is that transit riders have every right to take advantage of this outstanding public green space, which their tax dollars helped finance, and that doing so will make them more inclined to enjoy their transit experiences.

Mitigate for me, not for thee

Throughout his 20-minute rant against the FTA and GCRTA on December 30, Mayor Jackson kept repeating one word: mitigate.

He was trying to mitigate the risks of terrorism. FTA has an obligation to mitigate safety concerns. The City and GCRTA can mitigate service disruptions. There was no way for him to mitigate the pain and suffering Joan Keundig’s family is experiencing. Mitigate, mitigate, mitigate. But one thing the Mayor did not focus on was mitigating the burden placed upon bus riders who have been forced off of the Square.

The types of transit waiting environments that Lagune-Reutler et al outline, which can mitigate this burden, perfectly describe Public Square.

The bus stations are new, well-lit, largely protected from the elements, and include a transit system map. Bus riders on the Square are surrounded by other pedestrians – both transit users and non-users alike – and, frequently, police, providing additional eyes on the street, which can mitigate security concerns. The stations are flanked by new trees and vegetation, helping to address the tree cover variable. And Superior itself is dedicated for buses and bikes exclusively, mitigating concerns about traffic, noise, and air pollution. (The current arrangement, as I’ve demonstrated, exacerbates those issues.)

Honestly, if you read the description of the ideal transit waiting environment from the study, it just sounds like they’re describing Public Square to you:

First, creating exclusive transit lanes or streets reserved for transit, bicycles, and pedestrians (where feasible) is likely to reduce waiting time perceptions by increasing distances between waiting areas and automobile traffic. Second, the alignment of transit routes and the location of stops avoiding highly polluted areas where possible without affecting travel demand can also contribute to shorter perceived wait times…

The ability of the presence of trees to compensate for the negative effects of pollution and traffic suggests that planting trees or moving a problematic stop to take advantage of existing tree cover can significantly improve the user experience at a reasonable cost. This cost should be compared with other costs of measures able to enhance customer satisfaction such as higher frequency, transit information, and stop amenities.

As I’ve discussed more times that I care to count, public transit in Cleveland is in a crisis. Closing Public Square to buses exacerbates that issue, not only by imposing financial and logistical costs on GCRTA itself, but by making transit less desireable to users.

We spent $50 million in public and private financing to build a new Public Square that, by all regards, is a wonderful public space. Then our Mayor unilaterally decided to kick out the people who have historically used that space the most – bus riders. There is no longer any good argument to retain this status quo, and this study simply adds more weight to this conclusion. Bus riders deserve nice things too.

Don’t listen to NEOMG – closing Public Square to buses leads to more air pollution

One can generally count on Advance Ohio/NEOMG/Cleveland.com/The Plain Dealer/whatever they are going by nowadays to defend vigorously the interests of the entrenched powers-that-be. This outcome particularly holds true when it comes to shiny, big ticket megaprojects.

Regardless of whether or not said megaprojects actually have merit, Cleveland’s largest media conglomerate and newspaper seems all too happy to eschew logic or internal consistency in their quest to carry the water for the region’s political and business elite.

One need look no further than their breathless coverage last week of the “transformation plan” for Quicken Loans Arena. Cleveland.com even created a helpful landing page for the proposal, complete with 13 separate stories. Erstwhile good journalists twisted themselves into knots trying to defend a plan that will cost taxpayers some $160 million over the next two decades to bring up to snuff an arena that just hosted the Republican National Convention, in the hopes of “boosting the city’s ability to attract major events, such as political conventions.” Check your logic at the city limits, folks.

With all of that in mind, it is really no surprise that NEOMG/the PD/whatever would happily defend Cleveland Mayor Frank Jackson’s inexplicable decision to close Superior Avenue through Public Square to buses. A lot of ink and words have been spilled on this issue, and I’m not here to relitigate this fight. Instead, I just want to focus on a relatively narrow issue.

Two weeks ago, just days after a contentious City Council hearing on the issue, the PD published an editorial that dutifully parroted the Jackson administration’s talking points on the subject, right down to the hyperbolic fear-mongering about terrorist acts and bus drivers mowing down children in the street.

Putting aside those claims for a minute [which, honestly, we shouldn’t, because hoo boy], there was one particular part that really caught my attention,

Public squares were designed in a quieter time before terrorist considerations and wheezing block-long buses were prevalent.

When I read that sentence, I think my eyes damn near rolled out of my head and onto the floor.

Forget the absurd claim that “public squares were designed in a quieter time before terrorist considerations,” which is, obviously, insanely ahistorical. One can easily date terrorism back the first century CE, and the word itself has its origins in Reign of Terror during the French Revolution, which took place two years before Moses Cleaveland even established this city.

Leave aside the assertion that GCRTA employs “block-long buses,” which is preposterous. The average block in downtown Cleveland is roughly 500-600 feet long. GCRTA’s longest buses are…not.

About those “wheezing” buses…

But that’s still not what I want to talk about. While you may want an analysis of the merits – or lack thereof – of the arguments put forward by the administration and its water carriers at 1801 Superior Avenue, I gotta be me. And, as Area Air Quality Nerd, I cannot get past the “wheezing” part of that ludicrous sentence.

Read literally, the PD’s editorial board argues that allowing GCRTA buses to use the dedicated bus lanes on Superior Avenue through Public Square would allow them to belch out diesel exhaust, fouling air quality and damaging the lungs of passersby.

Except that is prima facie absurd. Perhaps the members of the editorial board don’t quite understand how mobile emissions work, but that isn’t it. On the contrary, forcing buses to travel around, rather than through, the Square should produce more emissions, as the buses are forced to drive farther and sit in traffic as they compete for road space with other vehicles. But how much?

Fortunately, I do this sort of thing for a living, so I can estimate the additional bus emissions associated with closing Superior Avenue through Public Square to buses.

The method to my madness

Let me briefly lay out my methodology. According to GCRTA data, roughly 1,445 buses drive through/around Public Square on a daily basis. Because those buses are not able to access their dedicated lanes on Superior Avenue, they are forced to transit another 0.1 miles around East Roadway/West Roadway/Rockwell, adding some 52,754.5 miles per year. Additionally, because the buses are now in traffic, they must travel at reduced speeds and idle as they wait to get back on Superior Avenue.

Below, I lay out the additional emissions that result from closing the Superior Avenue bus lanes through Public Square. In one scenario, I assume each bus trip is delayed by 2 minutes – the lower estimate which the administration provided at the Council hearing. In a second scenario, I assume each bus trip is delayed by 4 minutes, which, while double the administration’s estimates, is still below observed delays of 6 to 10 minutes from GCRTA riders. The former scenario leads to 17,851 idling hours per year, while the latter adds up to 35,162 hours.

I utilized MOVES2014a, the most recent version of the U.S. EPA’s mobile emissions modeling software, to develop emissions factors per mile and for each additional hour of idling for the GCRTA bus fleet. I then converted total emissions into additional metric tons per year. The results are shown below.

additional emissions public square

Additional emissions from closing Superior Avenue through Public Square to buses (authors estimates using MOVES2014a).

Closing Superior generates more emissions

As you can see, the additional distance the buses must travel (0.1 miles per trip), leads to de minimis emissions. But when you add in the idling emissions, those numbers climb significantly. Carbon monoxide (CO) emissions total 0.71 and 1.13 tons, respectively, based 2- and 4-minute delays, while nitrogen oxide (NOx) emissions total 1.96 and 3.16 tons, respectively. Closing the Square also leads to an additional 535.98 and 860.96 tons of carbon dioxide equivalent (CO2e) per year for each scenario, respectively.

And those emissions have real costs

On the whole, these are not particularly eye-popping numbers. But they do carry real costs and consequences. When the City of Cleveland and GCRTA initially sought federal funding for the Healthline BRT project in 2001, they estimated the emissions savings the project would generate. As the table below shows, the additional emissions from closing the Square to buses nullifies a portion of those emissions.

costs from additional public square emissions

Costs associated with additional emissions from closing Superior Avenue through Public Square to buses (authors estimates).

The additional CO emissions only takes away slightly more than 1% of the estimated savings; that said, vehicle CO emissions have plummeted nationwide since that point due to new vehicle emissions controls, so that’s not surprising. But the additional NOemissions could wipe away almost half the estimated savings under a 4-minute delay scenario.

These extra emissions carry real social costs. I have also estimate the social costs of the additional emissions, using damage estimates from the Federal Highway Administration. Again, the numbers are not staggering, but they do amount to tens of thousands of dollars in additional social costs tied solely to the Mayor’s decision to close a 600-foot piece of road.

Don’t forget those unknown unknowns

Furthermore, I cannot calculate any additional emissions that may result from the ripple effects of this ill-conceived decision. GCRTA has already cut more bus revenue miles than any other major transit agency, and it recently enacted a two-step fare increase. Add to that a potentially catastrophic budget hit from the loss of sales tax revenues on managed care organizations, and you have a recipe for disaster.

Tacking on another $1.6 million in operating expenses and increasing delays will make the experience worse for riders, possibly driving those who can afford it off the bus and into private cars. Given that GCRTA buses release 19% fewer average emissions per passenger mile than single-occupant vehicles (320 grams vs. 396 grams of CO2e, per my estimates), this outcome would just add even more emissions.

So while I expected the PD to support the Jackson administration’s choice, they should tread more carefully when it comes to verifiably inaccurate statements. There are no block-long buses hurtling through Public Square, belching out emissions. Just the opposite, in fact.

The startling costs of air pollution on unborn children

Industrial pollution obscures Cleveland’s cityscape in this 1960 photo from Robert Wyly (courtesy of Elvin Wyly).

In a developing fetus, one of the the last organs to form fully is the lungs. The National Institutes of Health (NIH) defines a preterm birth (PTB) as one that occurs before 37 weeks of gestation. This definition is, in part, due to the fact that the fetus does not begin to develop pulmonary surfactant, a vital lipoprotein that allows the lungs to remain expanded as one breathes, until around 30 weeks. All told, a child born before 36 weeks will struggle to breathe on his/her own.

PTB remains a serious issue in the United States. It is responsible for 35% of infant deaths, making it the single leading cause of infant mortality, and it can contribute to major cognitive and developmental disabilities. Given the vital role that lung function plays in infant health, it is clear that PTB directly affects a child’s ability to take in air. But what about the reverse? Could the air that a fetus (and its mother) breathes contribute to PTB? New research suggests that’s the case.

Drawing the link between air quality and preterm birth

Earlier this week, the journal Environmental Health Perspectives published a study from three researchers at New York University that explored the connection between air pollution and PTB. As I’ve noted in the past, there is a plethora of studies linking air pollution to low birth weight, PTB, and infant mortality. This study builds upon that literature by determining the proportion of PTB that is directly attributable air pollution.

In order to explore this issue, the researchers decided to examine the impact of the single worst criteria air pollutant, fine particulate matter (PM2.5). They assembled county level PTB values during 2010 from the Centers for Disease Control’s (CDC) WONDER database. Next, sing established epidemiological methods, they then calculated the proportion of PTBs in each county attributable to PM2.5 pollution, using a reference ambient concentration of 8.8 micrograms per cubic meter (μg/m3). This level of pollution is what the World Health Organization uses to determine the global burden of disease caused by outdoor air pollution.

Nationally, PTB rates have fallen to 11.3%, but they remain far too high. According to the study’s authors, 3.32% of all preterm births in the continental United States during 2010 were due to particle pollution. This amounts to 15,808 PTBs in that year alone.

Calculating the social costs of PTB from air pollution

But the authors did not stop there.  Theirs is the first study to quantify the economic impacts of this link. They developed estimates of the medical costs associated with PTB for children from birth through 5 years of age. To this value, they added the costs of lost economic productivity from reduced cognitive function and potential.

According to the study, the average premature child suffers an 11.9 point IQ decrement, which leaves them significantly disadvantaged compared to their peers.

Based on the best available data, the authors find:

These estimated numbers of attributable preterm births cost $760 million in medical care…and $4.33 billion…in lost economic productivity was also identified (based on estimated reductions in IQ and estimated consequences for productivity over a lifetime). In total, we estimated that $5.09 billion in preterm birth-related costs (medical care costs and lost economic productivity combined) could be attributed to PM2.5

Uneven distribution of costs

But, predictably, these costs are not distributed evenly among counties or demographic groups. The single highest fraction of PTBs attributable to particle pollution occurred here in Ohio, where 5.44% of all PTBs – 924 children in 2010 – are due to our polluted air. Compare this to New Mexico and Wyoming, states with drastically lower PTB rates, where the attributable fraction is just 0.12%. This leads to total annual costs of just under $300 million in Ohio: $253 million in lost economic productivity and $44.4 million in medical care costs.

Unfortunately, the authors did not provide supplemental data breaking down these attributable fractions and costs by county or metro area. They do provide a map that shows the percentage of PTB attributable to particle pollution by county, but it lumps all values above 5% together.

preterm birth from pollution by county

The percentage of preterm births attributable to particle pollution by county in 2010.

That said, Greater Cleveland has extremely high levels of both particle pollution and PTB. Cuyahoga County is one of just nine nonattainment areas for the 2012 PM2.5 standard, and Cleveland has the third highest PTB rate in the country. Pollution almost certainly accounts for a larger proportion of PTBs here then the state average. Additionally, based on data from the Ohio EPA, the annual ambient concentration of PM2.5 in Cuyahoga County during 2010 was 13.7μg/m3, 56% higher than the reference level of 8.8μg/m3 that the authors applied. Given this fact, I have to conclude that significantly more than 5% of PTBs in this region are tied to air pollution.

But let’s be conservative and assume that particle pollution is only responsible for 6% of preterm births in Cuyahoga County. That still means that the parents of 126 premature children born in 2010 can place the blame squarely on our elevated levels of particle pollution. If we raise this threshold to 10% – not an unreasonable assumption – this number increases to 209.

Additionally, Cuyahoga County accounts for 12.3% (2,093 out of 17,007) of all PTBs in Ohio during 2010. If we apportion this share, that means the county incurred $36.6 million in costs.

These numbers are equal parts dumbfounding and infuriating. The quality – or lack thereof – of the air we breathe day in and day out affects everyone of us here in Greater Cleveland. But it doesn’t just harm those of who have the means to choose where we live. It reaches into the womb and directly affects the futures of children who have never even taken a breath.

It’s well past time we stop pretending that air quality doesn’t affect every one of us profoundly and in a number of ways.

If you want to improve air quality, end the sprawl

For centuries, people have fled the supposed squalor of cities in pursuit of the fresh air that is so vital for our health and well-being. Before Louis Pasteur’s development of germ theory, most scientists and physicians subscribed to the belief that miasmas – essentially the foul smells associated with rotting organic matter – were the source of major diseases. The cure for illness, they argued, was for people to escape cities to get fresh country air.

Doctors prescribed fresh air as a treatment for various illnesses into the 20th century. American physicians encouraged their patients suffering from tuberculosis to head West in pursuit of the restorative benefits of the clean air. This movement helped foster the growth of many prominent Western cities, including Denver and Phoenix.

The clean air premium

Today, we tend to refer to the deleterious emissions that plague many cities by a different term: air pollution. But that same underlying precept – that we need to leave cities behind in the pursuit of fresh air and better health – remains.

Multiple studies demonstrate that people view air quality as an amenity and are willing to pay for it. According to economists Kennethy Chay and Michael Greenstone, reductions in particulate matter during the 1970s were “associated with a $45 billion aggregate increase in housing values,” while a separate study found that Americans were willing to pay $149–$185 for a one unit reduction in particulate matter levels.

Clearly, we place a premium on the concept of “fresh air.” But could our pursuit of this good actually be making air quality worse for others?

How might sprawl affect air quality?

The link between our sprawl-based development patterns and air pollution seems pretty obvious on the surface. The more we spread out, the more we have to drive to reach workplaces, schools, stores, entertainment venues, etc. All of this adds to vehicle miles traveled (VMT), and each additional mile we drive increases our mobile emissions.

But perhaps it’s not as simple as it seems. Moving people away from the worst polluters was clearly beneficial for public health. And pollution levels are typically higher in denser areas with high traffic volumes.

Additionally, one of the main targets of the landmark 1970 Clean Air Act Amendments (CAAA) was vehicle emissions. As a result, cars purchased today run more than 90% cleaner than those manufactured 46 years ago. This trend has helped to offset the rise in VMT. Thanks to these regulations, emissions of carbon monoxide and ground-level ozone have fallen by 85% and 33%, respectively, since 1980, while particulate matter emissions have declined by more than one-third since 1990. These improvements have occurred even as VMT has nearly trebled from 1.12 trillion when the 1970 CAAA was signed to just under 3.14 trillion last year.

With all of this in mind, I decided to comb through the literature to see what the best available science says on the relationship between sprawl and air pollution, and what I found may surprise you.

Just kidding, no it won’t.

Sprawl and air quality: The evidence

One of the first scholars to explore this relationship, in depth, was Brian Stone, Jr., who published his findings back in 2008. He probed the relationship between the number of days that ground-level ozone concentrations exceeded the EPA’s National Ambient Air Quality Standard (NAAQS) and sprawl index scores for 45 large cities from 1990 to 2002.

Stone, Jr. argued there are three major reasons that urban form could affect ozone levels. First, it can influence emissions of nitrogen oxides (NOx) and volatile organic compounds (VOCs), the two pollutants that combine to form ground-level ozone. Secondly, sprawling cities are more prone to the urban heat island effect, which can increase the ambient temperatures in urban areas by more than 20°F; higher temperatures facilitate the formation of ozone. Thirdly, large, sprawling cities are more likely to have a broad ozone monitoring network, which may increase the odds that high ozone levels are observed.

The study found a strong, statistically significant link between urban form and air quality, even when controlling for weather conditions. According to Stone, Jr.’s results, a one standard deviation increase a city’s sprawl index score produced 5.6 more ozone exceedance days per year. In turn, a one standard deviation increase in population density – one of the four components of the sprawl index – was associated with 8 fewer exceedance days. Based on his findings, he notes that “urban form is significantly associated with both ozone precursor emissions and ozone exceedances…Overall, the most sprawling cities were found to experience over 60% more high ozone days than the most compact cities.”

To put that into perspective, Cleveland has a composite sprawl score of 85.62, meaning it is just over 14 units less compact than the average metro area. If it was as dense as Madison, Wisconsin (136.69) or Detroit (137.17), we would have had 11.2 fewer ozone exceedance days per year through 2002. Given that we averaged 20.5 exceedances per year from 1997-2002, this would represent a 55% reduction.

Strengthening the connection

Multiple subsequent studies support these findings. A 2013 article from Bradley Bereitschaft and Keith Debbage examined the connections between ozone and fine particulate matter (PM2.5) emissions and five separate sprawl indices. Each of the indices computed sprawl in a slightly different way, accounting for various measures of urban form. The authors folded these into two key measures – urban continuity (the degree to which the urban landscape is fragmented) and urban complexity (the degree of the “jaggedness” of the urban boundary).

The authors note that each of the sprawl indices produced a significant connection between sprawl and pollution levels. A one standard deviation increase in the most prominent sprawl index score was associated with 3.4% and 7.8% increases in ozone and PM2.5, respectively. The density of residential properties appears to be a particularly important correlate for air quality. Increasing residential density by one standard deviation lowers ozone and PM2.5 levels by 8% and 16%, respectively. This change in density can also lower on-road CO2 emissions by an average of 1.9 million tons. Using a social cost of carbon of $37 per ton, this produces social benefits of $70.3 million.

Bereitschaft and Debbage argue that “an increase in residential density might improve air quality and contribute to a reduction in per capita CO2 emissions at the metropolitan scale primarily by decreasing automotive dependency and tailpipe emissions.”

Additionally, the authors examined the connection between urban form and the direct emissions of NOx, VOCs, and PM2.5. Their results are striking. A one standard deviation rise in urban shape complexity increases PM2.5 emissions by 3,055 tons (12.4%) per year. Using EPA damage factors for on-road emissions, this additional pollution would cause 128 to 287 premature deaths and carry public health costs of up to $2.47 billion per year.

If more sprawl leads to worse air quality, will reversing that trend in Rust Belt cities lead to cleaner air? Stone, Jr. looked at this issue in a 2007 piece for the Joumal of the American Planning Association. He studied how shifting from a business as usual scenario to a more compact growth approach modeled on Portland could affect VMT and air quality in 11 Midwestern cities through 2050. By shifting from our current sprawl-heavy trajectory, Cleveland could lower household VMT by 9% and reduce emissions of CO, NOx, VOCs, and PM2.5 by anywhere from 7-9.2% each.

All the evidence points to one conclusion – sprawl is exacerbating air pollution. In our haste to find fresh air, we’ve simply made things worse for those who do not have the means to keep moving farther and farther out.

As Bereitschaft and Debbage put it, “Planning for density therefore becomes an issue of environmental justice, particularly at the metropolitan level. Simulations suggest that by relocating to peripheral suburban areas, residents might reduce their exposure to certain air pollutants…[while] simultaneously contributing to a decline in regional air quality by increasing the total volume of automotive traffic.”

I’ve argued before that, despite our poor air quality, almost no one in Greater Cleveland seems interested in talking about the issue and how we might solve it. Perhaps that’s because, unlike in the past, the real source of the problem isn’t just some large coal-fired power plant or steel mill. No, the problem is our individual driving habits. We’ve met the enemy, and it is us. Unless we face up to that fact, we aren’t going to change things for the better.

Our pursuit of the American Dream is undermining it

When I was in high school, a teacher once asked my class to use a word or term to describe the United States. A classmate of mine said it was “a meritocracy.” The teacher, who wasn’t the sharpest knife in the drawer, wrote “Ameritocracy” on the chalkboard.

It was pretty funny — because words are hard — but it gets to a larger issue, albeit purely by chance. For most people, the US is so closely synonymous to meritocracy that they might as well be the same word. America is the land of opportunity; the American Dream claims that if you work hard and play by the rules, you can succeed and make a better life for your children.

One of the key vehicles by which to achieve the American Dream is home ownership. It’s the way most people set down roots and accumulate wealth. But what happens if the system we have developed to promote the vehicle (home ownership) undermines the goal itself?

New images show how freeways tore apart Cleveland’s neighborhoods

Carnegie-Ontario 1951

Earlier this week, Chris Olsen of ESRI uploaded some amazing aerial maps of Cleveland into ArcGIS, which document the land use changes in the region over the past 65 years. As we all know, since 1950, while Cuyahoga County’s population declined from 1950 to the present, the remaining population has spread out throughout it and neighboring counties. As a result, whereas just 26% of the county’s land was developed in 1948, this number exploded to 98% by 2002.

One of the major factors contributing to this trend was the development of the interstate highway system, which began after the passage of the Federal Aid Highway Act of 1956. Accordingly, the aerial maps from 1951 provide us with a snapshot in time just after the City of Cleveland’s population reached its peak of 914,000 and just before the highway system helped usher in decades of population loss and decline.

But, beyond just aiding the movement of people out of the City of Cleveland and into the suburbs and – eventually – exurbs, these images demonstrate the extent to which the Interstate Highway System devastated wide swathes of the city. Whole neighborhoods were torn apart as homes and businesses were demolished to make way for freeways. It would take decades for many of the neighborhoods carved up by these freeways, such as Tremont, to stem the associated decline. Other neighborhoods, such as Slavic Village and Clark-Fulton, have yet to rebound. The images below display what some of these areas looked like in 1951 and how these same areas look today, six decades later.

Gateway District (Downtown)

This image displays the southern reaches of downtown Cleveland, including the eastern end of the Lorain-Carnegie (Hope Memorial) Bridge and what is now known as the Gateway District. While this portion of downtown was densely developed through 1951, the construction of the Interbelt beginning in 1954 radically altered the area. The replacement of the Interbelt Bridge, which has since become functionally obsolete, is still ongoing.

Campus District (Downtown)

These images document the changes in the Campus District around Cleveland State University. CSU, which did not exist until 1964, has taken over a significant portion of the eastern section of downtown in recent decades. But this area was also divided in two with the construction of Interstate 90.

Slavic Village/East 55th Street (Near East Side)

Further east, we find the area around Cleveland’s Industrial Flats and East 55th Street. This neighborhood has seen its fair share of ups and downs over the years. The railroad depot in the upper right-hand quadrant was formerly known as Kingsbury Run; this was the location of the infamous Cleveland Torso Murders of the 1930s that eventually ended Eliot Ness’ career in law enforcement.  This same railyard is now the primary rail hub for the Greater Cleveland Regional Transit Authority. Ultimately, the images display the extent to which the construction of I-90 and, later, I-490, drove a massive wedge into this area. While the continuation of I-490 further east fortunately never materialized, the controversial Opportunity Corridor is essentially the reboot of this project.

Tremont/Industrial Flats (Near West Side)

Heading southwest across the Cuyahoga River, we find ourselves on the southern fringes of Tremont. Much like the areas around East 55th, Tremont has been broken into four sections by the junction of I-90/Interbelt and I-490. This newly trendy, gentrified neighborhood had historically been home to low-income, blue collar workers of various ethnic groups. When I-90 broke off the neighborhood off from Ohio City, located just to its northwest, Tremont entered into a decades-long decline.

Clark-Fulton/Stockyards (Near West Side)

Further southwest of Tremont is the Clark-Fulton neighborhood. This area, too, has historically been home to blue collar workers, hence its other moniker – the Stockyards neighborhood. The construction of I-71 and Ohio Route 176, which break apart in the upper right of the modern image (near the Alcoa plant) brought about the bulldozing of much of this neighborhood.

West Boulevard/Cudell (West Side)

Lastly, this image shows the change in area around West Boulevard/Cudell. This neighborhood has become notorious as the location where Cleveland police officer Timothy Loehmann killed 12-year old Tamir Rice. But if you drive down West Boulevard or West 98th Street, you can see that, decades ago, this area was home to upper middle class Clevelanders. Today, I-90 leaves a massive scar through the middle of the area, making large portions of the surrounding surface streets, like Lorain Avenue, extremely difficult and unpleasant to bike or walk across.

Ultimately, these aerial images provide a striking juxtaposition of two Clevelands: one at its economic zenith, the other struggling to emerge from its nadir. While the Interstate Highway System provided a lot of benefits to the United States that aided its post-war economic growth, these images really help us understand just how devastating that change was for cities like Cleveland.

Air pollution adds to a number of Cleveland’s ills. So why does no one talk about it?

Vehicle exhaust contains a number of harmful pollutants, including fine particulate matter, and it is increasingly the primary source of urban air pollution (courtesy of Wikimedia Commons).

A few weeks ago, Rachel Dissell and Brie Zeltner from The Plain Dealer released their roughly 26-part series,Toxic Neglect,” which provided an incredible deep dive into the City of Cleveland’s chronic lead poisoning crisis. The series is truly outstanding journalism, something that is becoming increasingly rare in Northeast Ohio these days, and enough to max out your rage meter. If lines like “[Cleveland puts] more money into baiting for mosquitoes to curb West Nile virus and to prevent rabies in raccoons than we put into lead poisoning” and “national policy for decades has been to use primarily poor, minority children as household lead detectors” don’t enrage you, you don’t have a heart.

Dissell and Zeltner’s thorough investigation shines a light upon a major issue that is too often ignored in this region – the fact that at least 2,000 Cleveland children are poisoned by lead each year – and documents the City’s completely inability (desire?) to mitigate the crisis. They attempted to put a price tag on the problem, noting that lead reduces IQ and lifetime earnings potential, increasing healthcare costs, and contributes to violent crime in a city already plagued by them.

Dissell and Zeltner do an incredible job of displaying how the environment into which Cleveland children are born and in which they are raised irrevocably affects their futures. Their investigation centers on the city’s legacy of lead paint in its aged housing stock, the chief source of lead in the region. While airborne lead used to be an urban scourge, tetraethyl lead was finally phased out of all gasoline in the US in 1996. While much of that lead remains in our contaminated soils to this day, it is no longer the main culprit.

This series is just the latest in a string of great work from Zeltner, including earlier explorations of childhood asthma and infant mortality. But whereas it makes sense to minimize the role of air pollution in the lead series, this omission makes far less sense in the other two cases. We know that it is a important driver for both. But, for some reason, people in Northeast Ohio keep turning a blind eye to a problem that, quite literally, is all around them at all times.

It was with all of this in the back of my mind that I read a recent article in the journal Environmental Health Perspectives that examined the impacts of vehicle emissions on the cognitive development of children. The study, written by a group of public health professionals in the Boston area, focused on how exposure to pollution from traffic during late pregnancy and early childhood affects the brains of children later in life. The authors looked at the results of cognitive analyses for 1,109 children, aged 6-11 years old, who were part of an existing health study from 1999-2002. Because they tapped into this cohort, the authors had access to data on a number of variables, including household income, mother’s IQ, exposure to lead, and whether or not the mother smoked. Accordingly, they were able to control for each of these factors when conducting their analysis.

They split their sample into three main groups: those children living less than 50 meters from a major roadway, those living between 50 and 200 meters away, and those living more than 200 meters away. These distances are significant, as coarse and fine particulate matter rarely travels more than 10 to 100 meters in the air before settling back to the surface. This allowed them to examine how children growing up in close proximity to heavy daily automobile traffic would fair later in life. The results were stark:

Among children residing primarily in urban and suburban Eastern Massachusetts, prenatal residential proximity to major roadways (< 50 m) predicted lower nonverbal intelligence, verbal intelligence, and visual motor abilities in mid-childhood.

Those children living closest to heavily trafficked roads scored, on average, 7.5 points lower on nonverbal IQ tests, 3.8 points lower on verbal IQ tests, and 5.3 points lower on visual motor skills tests. In other words, the cognitive effects of growing up alongside a major roadway is comparable to an increase from the 5th percentile of childhood blood levels to the 95th percentile. In fact, at a 6.9 point decline in IQ from lead, the effects of traffic appear to be even greater.

Interestingly, the authors were unable to find a statistically significant effect of traffic-related air pollution on childhood IQ, perhaps because the effects of pollution were so tightly entangled with socioeconomic factors.

But the evidence does not stop there. In a 2008 study using another cohort of children from Boston, Suglia and colleagues looked at the connection between early childhood exposure to black carbon, a particularly harmful component of fine particulate matter, and cognitive function when children were 8 to 11 years old. They found that children exposed to high levels of traffic-related black carbon pollution saw their IQ scores fall by 3 points, even when controlling for socioeconomic variables, exposure to tobacco smoke, and blood lead levels. The authors noted that this IQ decrement was comparable to those experienced by children born to smokers (4 points) and by children poisoned by lead (1-5 points). Additionally, a separate 2011 study found a connection between prenatal exposure to traffic pollution and an elevated risk of childhood autism.

All told, mounting evidence suggests that children exposed to high levels of traffic-related pollution before and after birth are far more likely to have lower IQs and to suffer from developmental disorders. Just because we rarely see visible pollution like that from the mid-20th century these days does not mean that the problem is behind us.

It’s incredibly important for a city like Cleveland, which is struggling to break free from repeated cycles of poverty and abandonment, to come to grips with this reality fully, for two main reasons.

First, it may force us to recognize the consequences of our individual actions. Our driving habits are responsible for the majority of fine particulates and nitrogen oxide emissions in this region. We are part of the problem. Maybe the girl growing up on East 79th or West 98th is struggling in school, at least partly, because of the toxic environment into which she born. If we finally start to talk about this, perhaps we can make changes, even if just on the margins. Was driving half a mile to the store really worth aggravating her asthma? Was idling so you could run the AC while waiting to pick up your child worth the extra pollution you exposed him to?

Secondly, acknowledging these issues will force us to rethink our regional development choices. If we want to help improve the lives of low-income Clevelanders, should we really be, say, building a $331 million urban highway that will just bring more traffic, noise, pollution, and dislocation to communities that already have a surplus of them? Is that wisest use of our limited resources? Are we honestly going to help lift people out of poverty by exacerbating some of its causes?

We can’t drive our way out of a driving problem, and we can’t sprawl our way out of a sprawl problem. I don’t know if air pollution is topic that can bring all of this to the fore. Obviously I’m biased. But it’s also a ubiquitous problem in this region, and it plays a factor in a host of our pressing problems. It’s time to make it a permanent part of the conversation.

Why developed countries should back loss and damage in Paris

A number of critical issues remain unresolved, including whether countries should set a maximum safe threshold for carbon emissions and what protocols will be put in place to ensure that parties are transparent and accountable for their emissions reduction commitments. One of the trickiest outstanding issues is the question of loss and damage. For years, developing countries have called for developed states to compensate them for the negative effects of climate change, such as more frequent flooding and more intense droughts.

While developed countries committed to provide financing for climate mitigation and adaptation through the development of the Green Climate Fund in 2009, it is widely acknowledged that there are impacts of climate change which we can neither prevent nor prepare for. These residual effects are at the centre of the loss and damage debate.

This issue particularly came to the fore at the 2013 Warsaw Conference, which took place in the immediate aftermath of Typhoon Haiyan, which devastated parts of the Philippines and killed more than 6,300 people.

Yeb Sano, the Philippines lead negotiator, delivered an impassioned speech in Warsaw pushing the issue. Sano, whose hometown had been flattened by the storm, fasted throughout the conference in solidarity with Haiyan survivors. He called for parties “to make clear the difference between humanitarian aid and climate change compensation in the context of historical responsibility.”

These efforts paid off, as negotiators created the Warsaw international mechanism for loss and damage, which created a standing committee to research the issue and advise the UNFCCC over the next two years.

At last year’s conference in Lima, negotiators reaffirmed their commitment to discuss the issue, outlined the membership of an Executive Committee, and approved a two-year work plan. But discussions remain in a preliminary phase, and many developing states remain concerned that the Paris talks may fail to address the question adequately. Small island states, in particular, view loss and damage as an existential question, as climate change may threaten their very survival.

What is the real cost of freezing Ohio’s clean energy standards?

I have asthma. According to the CDC, I am one of 831,787 Ohioans and 25.9 million Americans living with this condition (PDF). That means that 1 out of every 12 Americans is living with asthma, up from 1 out of 14 in 2001.

While people who may not have firsthand experience with this illness may not understand, asthma is far more than just an inconvenience. I’ve heard and seen children with asthma describe feeling like fish out of water when they are suffering an attack. It’s terrifying to not be able to get the air you need. While I don’t think I was ever really in any acute danger, the fact remains that 185 children and 3,262 adults died of asthma in 2007.

As much as I hate to admit it, asthma came to define much of my childhood. From the day that I was diagnosed at either 5 or 6 (I can’t remember the exact date), my severe asthma was omnipresent. Many of my memories from this period involve such episodes, including the role that my mom played in helping me deal with these attacks. Growing up, my mom routinely worked 60-hour weeks and stayed until 3:00 a.m. or later every Tuesday night to edit her newspapers. Despite this, she was always there to listen to my lungs to see if I was wheezing; to pick me up from school or practice if I had an attack; to ferry me to and from the the ER when I needed treatment; and to sit next to me in the hospital for the long hours while I underwent tests, got chest x-rays, and did my nebulizer treatments.

I vividly remember my first major asthma attack. It was the spring of 1993, and I started having breathing trouble towards the end of the school day. The attack only got worse throughout the afternoon, and when my mom got home from work around 6:00 p.m., she immediately drove me to the ER at Fairview Hospital. We sat in that ER for hours before a doctor could see me and for several hours more before they were able to admit me for care. My mom stayed with me right until they took me up to my room for admittance at 3:30 a.m. I ended up spending three days in the hospital for treatment and observation (thankfully, it was the only time that I actually got admitted for asthma). This is just one of the thousand acts of kindness from her that I can never fully repay.

Fortunately, as I got older, I began to grow out of this severe asthma. Today, I am able to live a normal life without worrying about when my next attack will come. But, at the same time, I know that the threat remains, and I have my emergency inhaler on hand, just in case. I was reminded of this quite vividly back in the fall of 2005 when I went in for routine surgery. The procedure required me to go under general anesthesia, so the doctors intubated me. But, after the surgery, when they tried to remove the tube, I suffered a severe bronchial spasm that cut off my breathing. My blood-oxygen saturation levels plummeted into the mid to upper 60s (normal levels are 95-100%), and I ended up spending the next 24 hours in the ICU, an experience I recommend avoiding, if at all possible.

I have no idea how much my asthma diagnosis ended up costing my parents in medical bills and lost time at work, but I imagine the amount was substantial. I did see the medical bills that came in during my stay at the ICU and, even with insurance, they were staggering. For the millions of Americans who suffer with asthma everyday, many of whom do not have insurance, this diagnosis is a real burden. On average, asthmatics spend $3,300 in medical costs each year. According to CDC numbers, asthma costs total $56 billion in direct medical costs, lost school and work days, and premature deaths. Everyday in this country, 36,000 children miss school and 27,000 adults miss work due to this condition.

My past (and present) as someone living with asthma has made me an advocate for clean air. We know that air pollution is both a root cause of the condition and a proximate trigger of asthma attacks. And that’s what pisses me off so much at SB 310. By crippling Ohio’s clean energy industry and protecting the fossil fuel industry, it will directly contribute to more asthma attacks and more chronic pulmonary diseases. This bill will carry a high cost in blood and treasure for our state.

It’s great to focus on how this bill will destroy jobs and harm a thriving clean energy industry in the state (which I’ve done), but SB 310 proponents just counter with their BS “war on coal” retort, a completely disingenuous argument that is, nonetheless, powerful in this state. But it’s another thing entirely for proponents of this bill to hear about the ways that it will directly affect the health of thousands of Ohioans and just not even give a shit.

Yesterday. the Ohio Environmental Council released this infographic showing the benefits of the state’s clean energy standards during 2013:

oec clean energy infographic

Using these numbers and EPA incidence factors, we can roughly calculate the economic and health benefits of the clean energy standards in 2013 alone. According to 2011 EPA standards, every ton of NOx, SO2, and PM2.5 has has the following benefits:

incidence factors for power plant emissions

Source: US Environmental Protection Agency

Accordingly, using these numbers, the reductions in NOx and SO2 emissions saved 3.5 lives, 267 lost work days, 59 asthma attacks, and 2.5 non-fatal heart attacks last year alone. And, based on Lepuele et al.’s economic benefit estimates, these standards had a health-related economic benefit of $208,620,000 in 2013.

But these numbers don’t even take into account the social benefit of the greenhouse gas emissions avoided by the standards. The US government currently uses $37 per ton as its social cost of carbon emissions. Accordingly, given that these standards saved 1,061,300 tons of GHGs in 2013, they created an economic benefit of $39,268,100. In total, using these conservative estimates, Ohio’s clean energy standards generated an additional economic benefit of $247,888,100 in 2013 alone.

These savings are not included in other analyses, but they are real, and they affect the lives of ordinary Ohioans everyday. The facts are clear – a vote for SB 310 is a vote for more asthma attacks, more heart attacks, more work and school days missed, more trips to the ER, more premature deaths, and more of the carbon pollution that is driving climate change. These are the the stakes.

If SB 310 proponents really wanted to show the real cost of these standards on Ohioan’s electric bills, as they claim, they should include a provision in the bill that requires the inclusion of these numbers. Somehow I doubt that would go over too well.
