Stronger Ozone Standards Will Secure Healthier, Longer Lives for Millions of Americans

By Elena Craft, PhD / Published: June 6, 2013

(Originally posted yesterday on EDF Voices)

For some time, public health and medical experts have been clear that the Environmental Protection Agency’s air quality standard for ozone, the primary ingredient in smog, isn’t doing enough to protect Americans from serious health risks.

Unfortunately, before EPA even proposed new health standards in response to rigorous science, the American Petroleum Institute (API) attacked with sky is falling claims that 97% of businesses in America would shut down.

This is quintessential beltway politics: fact free and designed to hide the real issues.

As a health scientist, I think the facts matter. And the bottom line is that EPA has a responsibility to adopt health standards anchored in science. So let’s take a closer look at what the science tells us.

Ground-level ozone is the main component of smog and is the single most widespread air pollutant. Ozone is linked to premature deaths, increased asthma attacks and breathing problems, as well as increased emergency room and hospital admissions. This pollutant poses an especially serious risk to children, seniors and people with lung diseases like asthma and bronchitis.

The Science is Sound

The science on ozone’s health effects is rock solid. Evidence from more than 1700 peer-reviewed scientific reports (which continues to be reinforced by new data) clearly shows that our current ozone standard isn’t doing the job of protecting the public health. We need to strengthen that standard.

The Clean Air Scientific Advisory Committee (CASAC) – the body that makes science-based recommendations to EPA – has issued multiple statements indicating that the current ozone standard of 75 parts per billion (ppb) is unacceptable with regard to protecting human health.

And new research, including recent reports demonstrating a significant increase in pulmonary inflammation in healthy individuals exposed to 60 parts per billion (ppb) ozone, supports this analysis and highlights the urgent need for a more health-protective standard.

Need for an Adequate Margin of Safety

By law, EPA must set national health-based standards that protect human health with “an adequate margin of safety.” To do this, the agency considers factors including the nature and severity of the health effects involved, the size of the at-risk populations, and the scientific uncertainties that must be addressed.

How do these factors add up in the case of ozone?

The nature and severity of the health effects involved: It is hard to imagine health effects more severe than death or the inability of a person to breathe without a struggle, especially if it’s a small child who has to be rushed to the emergency room.

The size of the at-risk population: Nearly 34 million Americans have been diagnosed with asthma during their lifetimes and estimates predict that number will grow by more than 100 million by 2025. Nearly 12 million people suffer from chronic obstructive pulmonary disease (COPD), a disease that causes serious, long-term disability and kills more than 120,000 Americans each year. And that’s only a partial list of those at increased risk from ozone.

The degree of uncertainties that must be addressed: Evidence continues to accumulate of effects in healthy people at exposures as low or lower than 60 ppb. Thus, if uncertainty is part of the decision making process, then EPA is obliged to adopt a standard even more protective than the one recommended by CASAC.

Here We Go Again: Unfounded Claims Concerning Economic Impacts

These kinds of sky is falling prognostications are not new. As far back as 1997, when EPA was considering one of the first revisions to the ozone health standard, Senator Spencer Abraham (R. MI) was among many who claimed that the new standards would have devastating economic impacts. “Dry cleaning establishments, hair salons, and other small businesses will not be able to absorb the increased costs imposed by these regulations,” the Senator said.

Those claims proved to be entirely false. In fact, in fact, Texas has made the case that the Gross Domestic Product (GDP) has gone up even as ozone controls strategies have been adopted, resulting in cleaner air across the state.

Old scare tactics die hard. That’s why today API and others are again trying to stop reform of the ozone standards by making the same sort of unfounded claims that all businesses will close the doors. But environmental protection is, or should be, a health issue, not a political football. And it’s on the ground of health that that The American Academy of Pediatrics, the American Medical Association, the American College of Chest Physicians, the American Public Health Association and the American Thoracic Society have all endorsed CASAC recommendations for new ozone standards.

In the end, EPA should not be swayed by “sky is falling” claims, whether from the petroleum industry or any other group. We urge EPA not to delay adoption stricter ozone standards. To do so would be to needlessly threaten the health of millions of Americans.

Facing a Frightening Milestone: What We Can Do About Greenhouse Gas Levels at 400 ppm

By Ben Schneider / Published: May 30, 2013

We recently learned that the earth’s greenhouse gas levels are surging past 400 parts per million (ppm), a level not reached in 3 million years. It is clear why: humans are releasing carbon dioxide into the atmosphere at an ever-increasing rate, including last year’s all-time high of 35 billion tons. And as the planet warms as a result, we’re getting an early glimpse at the superstorms, drought and other challenges we’ll face in an increasingly dangerous environment if we don’t change course.

Lots of people are rightly worried, and the media have largely focused on the worst potential outcomes for us and future generations if we don’t curb emissions. It’s important for everyone to know what’s at stake, but it’s also crucial that everyone understands we’re not helpless to act. There are steps we can take that will make a real difference, as individuals and as a country. So before you become too pessimistic about the milestone, take a look at some of the ways we can do something about it:

Continue to feed the conversation.

Whether in the media or at your dinner table, simply talking about why 400 ppm is important will inform others and keep climate change at the front of everyone’s mind. It will be especially important to include less traditional allies whom studies show increasingly recognize the reality of climate change.

Reduce climate accelerants.

Because it burns cleaner than coal, natural gas can be a positive for our climate. The challenge is that natural gas comes with its own set of serious risks to public health and the environment, and methane (the main ingredient in natural gas) is a greenhouse gas many times more potent than carbon dioxide. We must ensure this resource is harnessed in a way that minimizes methane leakage and has as little impact on people and the environment as possible. No one should have to trade their health or quality of life for cheap energy.

Accelerate the transition to a clean energy economy.

The U.S. is poised to spend around $2 trillion over the next two decades replacing our antiquated electricity infrastructure, creating a once-in-a-generation opportunity to revolutionize how we generate, distribute and use electricity. We must seize this opportunity to modernize our electricity grid and put the right policies in place to accelerate investments in clean, homegrown renewables, energy efficiency and other innovative ways to generate and use energy. These approaches can address the need for power, spur economic development, lessen our carbon footprint and help America gain a global leadership position in the multi-trillion dollar clean energy economy.

Use the Clean Air Act.

The Administration is authorized to use the Act to reduce greenhouse gas emissions. President Obama should utilize it to both establish new CO2 emission standards for power plants and vigorously defend the rules he has already put in place.

Put a price on carbon.

We must acknowledge and act on what economists from across the political spectrum have long argued — the most efficient way to cut carbon pollution is with a cap or tax. Either would be a powerful tool that would help drive cleaner power developments. We could ease the impact on working families and businesses through lower taxes on either labor or capital.

The 400 ppm milestone is a reminder that the status quo won’t do if we want to protect the world we leave our kids. But the news has prompted new conversations about emissions across the country. I hope we seize this opportunity to talk not only about how we got here, but more importantly, what we’re going to do about it.

Wanted: Sound Climate Science from the House Science Committee

By Steven Hamburg / Published: May 30, 2013

House Committee on Science, Space and Technology Chairman Lamar Smith recently wrote an op-ed in the Washington Post that dangerously distorted the science behind man-made global warming.

It is patently false to suggest, as Chairman Smith did, that there is a “great amount of uncertainty” regarding the fundamental science underlying our understanding of the drivers of climate change. Man-made warming has been confirmed repeatedly by the vast majority of scientific organizations including NASA, the National Academies of Science and the American Meteorological Society. A recent review also reaffirmed that 97% of peer-reviewed scientific publications that address the causes of climate change endorse the consensus that climate change is real and man-made.

Chairman Smith argues that since the US decreased its greenhouse gas emissions between 2005 and 2012 we cannot be responsible for global greenhouse gas emissions. However, carbon dioxide remains in the atmosphere so long the US is responsible for more of the warming we are currently experiencing than any other nation.  In 2011, the United States’ emissions remained the second highest behind only China, a country with more than four times the population of the US.  The US continues to emit significantly more greenhouse gas per person than does any of the larger nations of the world, the few smaller exceptions are major fossil fuel producing countries. The fact that the US is not currently the single largest emitter is no excuse not to lead on addressing climate change.  The logic used by Chairman Smith implies that we should only ask the very largest emitters to clean up criteria air pollution or water pollution across the US. If we utilized that strategy our water and air would not have seen the improvements of the past 40 years, which have reduced death rates and restored the places we cherish.

He also discusses recent findings that temperatures have not warmed significantly in the past 15 years, which is not actually the case – rather several cooler years has reduced the rate of warming, as it has several times over the past decades of rapid warming. As EDF Vice President Nat Keohane recently wrote in response to this finding, this “underscores the fundamental nature of climate change — that we are creating dangerous uncertainties” and there are various explanations for this finding, notably that an unusual amount of heat has been stored in the deep ocean, rather than at the surface.

Chairman Smith also claimed that Hurricane Sandy was not caused by climate change. Scientists, including Kevin Trenberth of the National Center for Atmospheric Research, Bob Corell from the American Meteorological Society and Jeff Masters of Weather Underground and formerly of NOAA, confirm that Sandy’s damage was increased by rising seas, warming oceans, and was consistent with scientists’ climate predictions based on a warming artic. Just as we can’t say that steroids caused any one home run by Barry Bonds, steroids sure helped him hit more and hit them farther, and now climate change is increasing the likelihood of extreme of weather events, giving us weather on steroids.

Lastly Chairman Smith says that greenhouse gas regulations would hurt our economy. He does not account for the economic costs of inaction on climate change that many studies say outweigh the cost of action. Three of the most costly weather disasters in the US, Hurricanes Katrina and Sandy, and the 2012 Midwest drought, have happened in the past 6 years, costing $128 billion, $62 billion and $35 billion respectively. American taxpayers are footing a large portion of this cost including $12 billion from Sandy and $16 billion from Katrina under the National Flood Insurance Program, and $11 billion in crop insurance claims from the 2012 drought. These costs will only continue to increase as the effects of climate change become more apparent.

I appreciate that Chairman Smith is writing about climate change because it is a critical national debate. As chairman of the House Science Committee, however, he should start that discussion by acknowledging the most important and sound scientific facts: Climate change is real, it is caused by pollution from human activity, and it will become increasingly expensive for the US and the world.

The Not-So-Strange Bedfellows on Tier 3 Clean Car Standards

By Mandy Warner / Published: May 20, 2013

Most Americans rely on cars every day — cars that transport us to work and school, but that emit harmful soot, smog, and other dangerous air pollutants that impact human health.

We’ve posted before about a new way to clean up that pollution – the Tier 3 standards.

EPA has introduced these modern clean air standards to reduce harmful emissions from two sources — new cars and gasoline.

These complementary standards will ensure healthier, longer lives for millions of Americans – all for less than a penny a gallon.

Like so many other clean air issues, this one has brought together a strong, diverse coalition of groups in support of the updated, common-sense standards.

Supporters include car companies, manufacturers, environmental justice groups, health groups and medical professionals, labor, states, environmental groups, faith groups, and advocates for consumers.

EPA recently held two public hearings about the Tier 3 standards, in Philadelphia and Chicago.

We posted earlier about strong support for these clean air standards in Philadelphia. And EDF’s Graham McCahan testified on our behalf in Chicago, and said the turnout and support for Tier 3 was impressive there too. (You can read Graham’s testimony here).

Representatives of many of those other diverse organizations testified at the public hearings as well, in support of the Tier 3 clean air protections for Americans.

Here are a few quotes from the testimony:

Tier 3…is yet another example of the auto industry working with the Federal government, the state of California and other stakeholders to develop a harmonized approach that benefits all fifty states. It builds upon the successes we’ve had in the 2012­­–2016 and 2017­–2025 national greenhouse gas and fuel economy programs. It stays true to the simple principle of providing the cleanest vehicles to everyone throughout this great country.

The emission reductions that would result from the Tier 3 program proposed by EPA will benefit the citizens in every state and locality across the country…State and local air pollution agencies are relying on EPA to adopt the Tier 3 rule.

Low sulfur gasoline not only enables advanced technologies to achieve intended emission benefits, it has an immediate and significant effect on the 250 million vehicles on the road today, lowering emissions and helping states achieve attainment of ozone National Ambient Air Quality Standards (NAAQS).

  • Chrysler Group LLC

Our analysis estimates that by 2030, these standards under consideration today will prevent more than 2,500 premature deaths and more than 15,000 asthma attacks each year.

Building cleaner, more fuel-efficient cars creates jobs by sending money otherwise spent on fuel back into the U.S. economy, and also through the development and production of new, more efficient vehicle components. The Tier 3 standards will only bolster the auto industry’s ability to meet a strong fuel efficiency standard and generate these net positive economic outcomes.

These compelling testimonials are just a few of the comments made in favor of the Tier 3 standards.

If you didn’t have a chance to testify, you can still make your voice heard by sending an email to EPA. EDF has created a website to make it easy for you to stand up for the Tier 3 standards.

When America works together, we can achieve vital public health protections for our families and our communities – and create a stronger nation.

EDF Goes Back to Court to Support Climate Pollution Reductions

By Peter Zalzal / Published: May 8, 2013

Another high-profile clean air case played out yesterday in the U.S. Court of Appeals for the District of Columbia Circuit.

A three-judge panel heard oral arguments in a lawsuit filed by the state of Texas and some industry petitioners.

The lawsuit challenges EPA’s efforts to ensure smooth, uninterrupted permitting for large new industrial sources of climate pollution in Texas.

EDF was part of a coalition of clean air advocates that filed two briefs in the case. We filed in support of EPA, along with Conservation Law Foundation, Natural Resources Defense Council, and Sierra Club.

At issue in the case are State Implementation Plans, or SIPs as they’re commonly known.

Here’s some background on the case

U.S. clean air laws require that large new industrial sources obtain construction permits providing for cost-effective modern solutions to mitigate climate pollution. The states are empowered to provide those permits – through their SIPs.

In 2010, EPA found that 13 states, including Texas, lacked the ability to carry out that requirement.

All those states except Texas worked with EPA to ensure permitting authority was in place. That allowed large new industrial sources in those states to obtain the needed construction permits.

In an August 2, 2010 letter to EPA, Texas wrote that it:

ha[d] neither the authority nor the intention of interpreting, ignoring, or amending its laws in order to compel the permitting of greenhouse gas emissions.

That brings us to the lawsuits.

Here’s a look at what happened in court yesterday

Judges Judith Rogers, David Tatel, and Brett Kavanaugh heard oral arguments.

The judges closely questioned Texas and industry petitioners about the impact of the court’s recent decision in another case that we’ve written about.

In that challenge to the Endangerment Finding, before the same court, judges upheld EPA’s first-generation climate protections.  The decision in that case said that EPA’s interpretation of the Clean Air Act was:

unambiguously correct

In light of that earlier ruling, EPA argued that its actions were necessary to ensure that sources in Texas could get permits.

That became one of the main points of discussion during oral arguments yesterday – as the judges pressed Texas and the industry petitioners to describe how EPA’s actions caused them any injury.

What’s at stake in the case

This case is part of an extensive suite of litigation Texas has mounted to oppose some of America’s most important climate protections.

Those protections include:

  • EPA’s finding that greenhouse gases endanger human health and the environment
  • EPA’s Clean Cars standards, which will save consumers money, reduce pollution, and help protect our nation’s energy security
  • EPA’s requirement that large sources of greenhouse gas emissions deploy modern pollution controls

If successful in this case, the upshot of Texas’s actions would be to eliminate any authority from which new industrial sources in the state of Texas could obtain permits addressing their greenhouse gas emissions – permits which these sources need for lawful construction.

Texas is suing even though EPA has taken great pains to create a reasonable and fair process:

  • EPA has acted in the most limited, surgical fashion to ensure businesses in Texas can obtain permits consistent with the nation’s clean air laws.
  • EPA has provided federal authority only for climate pollution, and Texas is administering the balance of the requirements.
  • Even with respect to greenhouse gases, EPA has urged Texas to take delegated authority over permitting.

Unfortunately, as Texas continues to devote scarce public resources to suing over the common-sense climate protections of U.S. clean air laws, communities in Texas are already suffering from the weird weather linked to climate change – like last year’s debilitating drought.

And in an ironic twist, at the same time that Texas is using public resources to fight common-sense climate pollution standards, Texas leads the nation in wind power — a zero-emitting resource.

In 2012, wind power led the entire nation in the overall deployment of new electricity generating resources, with 13,124 megawatts.  Much of that came from the Heartland — Texas, Iowa, Oklahoma, Kansas and Colorado.

That means Texas is looking at a … well … Texas-sized economic opportunity – as well as an opportunity for climate progress.

What a shame they’re choosing to waste their time and money in court instead.

Linkage Approval Boosts Cap-and-Trade Momentum

By Erica Morehouse / Published: April 24, 2013

(This was originally posted on EDF’s California Dream 2.0 blog)

Don’t look now, but California’s cap-and-trade program is going global.

With California Air Resources Board (CARB) approving linkage between California and Quebec’s cap-and-trade programs today, these two programs will now be able to trade emissions allowances across borders starting in 2014.  CARB’s action comes on the heels of California Governor Jerry Brown’s recent decision to approve the linkage, which will increase the size of California’s cap-and-trade market by 20 percent. More importantly, linkage will boost California’s clean energy economy by creating a broader market for innovative, low-carbon technologies.  The linkage is also a shot in the arm for global efforts to cut greenhouse gas emissions, and it sends a positive signal to other jurisdictions that are working on building their own carbon markets and might ultimately seek to join with California and Quebec.

This linkage comes at a moment when momentum for carbon market development has been building around the world. Many other regions, including Europe, Australia, South Korea, and the Northeastern U.S., have instituted or are currently developing carbon markets. Australia also announced plans last August to phase-in a linkage with the EU system starting in 2015.

California Governor Jerry Brown also recently returned from a trip to China where he signed an agreement with their Minister of Environmental Projection to help reduce air pollution and an agreement with Guangdong Province to share best practices related to cap-and-trade, clear evidence that if we want to get serious about climate change, California or one region can’t do it alone.

Before full linkage is possible, it’s often helpful for governments to develop ‘unofficial links’ in the form of partnerships to share policies, best practices, and goals. This cooperation – which California and Quebec have had since 2007 – is important and beneficial for the overall growth, rigor and integrity of carbon markets. The California cap-and-trade system uses a similar platform to the RGGI system in the Northeastern U.S., and the California system has been carefully crafted based on lessons learned from the EU ETS.

It took many steps to get to this point, but with a first joint cap-and-trade auction now scheduled for early 2014, California and Quebec are finally there. CARB’s approval of linkage is a big milestone for California and the nation, and another strong signal of California’s leadership in fighting climate change, while moving the nation further down the path to a clean energy economy.
