Climate 411

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.

Litigation by Coal Interests Attacks EPA’s Landmark Clean Car Standards

By Pamela Campos / Published: April 19, 2013

Yesterday, coal interests petitioned the United States Supreme Court to review and overturn the nation’s landmark climate pollution standards for passenger cars and trucks.

These Clean Car standards are already reducing greenhouse gas emissions, while driving down our dependence on foreign oil and saving American families money at the gas pump.

They are broadly supported by the U.S. auto manufacturers, the United Auto Workers, national security experts, the Consumers Union, and numerous states.

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit unanimously upheld these common-sense standards on June 26, 2012. But some coal interests want to turn back the clock on actions that the courts have already deemed “unambiguously correct.”

Yesterday, in its petition to the High Court, the “Coalition for Responsible Regulation” attacked the foundation of our nation’s Clean Car standards. (You can read more about this industry group here)

These seriously misguided legal claims attack the critical societal benefits of the Clean Car standards for model years 2012 to 2016 and a second round of Clean Car standards for model years 2017 to 2025.

Together, the Clean Car standards will almost double the current fuel economy performance of cars on American roads – to an unprecedented fleet wide average of 54.5 miles per gallon by 2025.

That increase in fuel economy will be a huge financial benefit for American families. They’ll save an average of more than $8,000 in fuel costs over the life of a new car and ensure our country will see $1.7 trillion dollars in fuel savings.

For families purchasing a model year 2025 vehicle, this will be equivalent to lowering the price of gas by approximately $1 a gallon.

The Clean Car standards will also reduce carbon dioxide pollution by more than 6 billion metric tons over the life of the program – comparable to the total emissions from the United States in 2010.

These standards will reduce oil consumption by an estimated 2 million barrels a day in 2025 – as much as half of what we import from OPEC each day.

But we won’t have to wait until 2025. We’re already seeing significant efficiency improvements.

EPA’s preliminary data for model year 2012 cars shows the largest annual fuel economy improvements since EPA first began tracking this kind of data back in 1975. And in March 2013, the average fuel-economy sticker value of new vehicles sold in the U.S. was a record-high 24.6 mpg.

All of this is happening without loss of consumer choice, as more SUVs, minivans, and pickups beat the 20 mile per gallon benchmark, and new technologies such as hybrids are more commonly available.

In other words, our automotive industry can — and is — meeting the challenging of providing fuel efficient, low emitting passenger cars that consumers want to buy.

That’s why automakers are not appealing the case.

In fact, the Alliance of Automobile Manufacturers – an association of 12 vehicle manufacturers including Chrysler, Ford, and General Motors – supports the clean cars standards.

Here’s what their spokeswoman, Gloria Bergquist, said when EPA’s greenhouse gas rules were upheld last summer:

Automakers are already producing almost 300 highly fuel-efficient models, so we have made a huge investment in technologies and want to sell these models in high numbers.

It’s time for these obstructionist coal interests to end the litigation. America is moving forward, together, with innovation that will strengthen our nation’s security, our economy and our environment.

Tier 3: What It Means and Why It Matters

By Mark MacLeod / Published: April 4, 2013

By now, you’ve probably seen lots of news headlines talking about the proposed updated Tier 3 standards.

Tier 3 is the shorthand term for national vehicle emissions and fuel standards that will help us make big strides towards cleaner, healthier air. They are designed to reduce the soot, smog and other types of dangerous pollution that come from the tailpipes of our cars and trucks.

The U.S. Environmental Protection Agency (EPA) just announced the proposed standards to enthusiastic responses from everyone from health advocates to automakers (including EDF, of course).

What exactly are the Tier 3 standards, and why are they so important? Here are answers to some common questions:

What’s the story behind the Tier 3 standards?

Cars and trucks are one of the biggest sources of air pollution in America. For years, EPA has been looking for ways to reduce the pollution associated with those motor vehicles.

In 2000, they created standards that would attack the air pollution problem at two of its sources at the same time – by reducing impurities in gasoline, so what you put into your car is cleaner, and by improving cars’ emission systems, so what comes out of your car is cleaner.

They called these standards Tier 2.

Now, EPA is proposing to update the standards. The new, improved version – called Tier 3 – will keep the proven approach of treating vehicles and fuels as an integrated system.

Starting in 2017, the new proposal would strengthen the earlier standards in order to reduce the pollutants from both gasoline and auto emissions standards in the most cost-efficient ways possible.

The proposed Tier 3 standards are also designed to work in harmony with America’ new clean car standards, which will improve fleet-wide fuel efficiency in new cars to 54.5 miles per gallon by the year 2025, and with California’s state standards, which are already stricter than the national average.

How exactly would the Tier 3 standards work? 

Cars and light trucks are the second largest emitters of oxides of nitrogen and volatile organic compounds in the U.S. Those are the primary pollutants that form ozone.

According to EPA, the proposed Tier 3 standards would slash the level of those pollutants by 80 percent.

The proposed Tier 3 standards would also establish a 70 percent tighter particulate matter standard. Particulate matter, more commonly known as soot, is one of the most dangerous types of air pollution. It has been linked to asthma attacks, bronchitis, heart attacks and other types of heart and lung diseases.

The proposed Tier 3 standards would reduce other noxious types of air pollution as well, including carbon monoxide, benzene and butadiene. They would reduce fuel vapor emissions to near zero.

At the same time, the proposed Tier 3 standards would reduce the amount of sulfur in gasoline by more than 60 percent, to no more than 10 parts per million of sulfur on an annual average basis by 2017.

Lower sulfur levels in gasoline will allow vehicles to run more efficiently.

It also means we’ll see immediate benefits once the proposed standards go into effect in the year 2017. That’s because older cars that are already on our roads will emit less tailpipe pollution –right away — thanks to the cleaner gasoline. (The cleaner emissions systems will be built into new cars, and we’ll see those additional benefits emerge more gradually as Americans buy those cars to replace their old ones).

What are the benefits of Tier 3?

Tier 3 would be good for public health and for the economy

By the year 2030, EPA estimates that Tier 3 would:

  • Prevent up to 2,400 premature deaths every year
  • Prevent 3,200 hospital admissions and asthma-related emergency room visits every year
  • Prevent tens of thousands of cases of respiratory illnesses in children every year

EPA also estimates that by 2030, Tier 3 would prevent 1.8 million lost school or work days each year, and would provide total health-related benefits worth up to $23 billion per year.

How much will Tier 3 cost?

We can reduce tailpipe pollution and provide healthier, longer lives for millions of Americans for less than a penny per gallon of gas.

How will America’s gasoline standard compare to other countries?

The proposed Tier 3 standards for sulfur levels in gasoline are similar to levels that are already required – and being achieved – in Europe, Japan, South Korea, and several other countries (as well as California, here in the U.S.).

Do businesses support Tier 3?

Many businesses do support updating the standards, including automakers and the emissions control industry.

Tier 3 would provide greater regulatory certainty for automakers; a national standard means the auto industry can build a car that can be sold anywhere in the country.

On the day the proposed standards were announced, Michael Stanton, president and CEO of the Association of Global Automakers said:

We have been anxiously awaiting this rulemaking because it is good for the environment and will help harmonize the federal and California programs for both vehicles and fuel …  With 15 million new vehicle sales a year, automakers need predictable national fuel quality at the retail pump. Ultra-low sulfur gasoline is already available in California, Europe, and Japan and will enable automakers to use a broader range of technologies to meet the significant environmental challenges facing the industry.

Gloria Bergquist, Spokeswoman for Alliance of Automobile Manufacturers said:

This is a big step forward for this country to catch up to the clean fuels available in other industrialized nations. Automakers have already reduced vehicle emissions by 99 percent, and we’re working to go further while also delivering high quality, affordable vehicles to our customers.

And the United Auto Workers said:

This is one of the most cost-effective ways for us to get cleaner and healthier air while strengthening our domestic auto sector and creating thousands of new jobs … The proposed rule is a win for our economy and a win for public health.

Who else supports Tier 3?

Even before EPA unveiled its proposal, state and local officials, national recreation groups, health groups and the public – as well as the automakers and the emissions control industry — all announced their support for updating the standards.

EPA has compiled a list of what all those supporters are saying. It’s a very long list. You can read it here.

What happens next?

EPA will hold two public hearings about the proposed Tier 3 standards, the first on April 24th in Philadelphia and the second on April 29th in Chicago.

EDF will be sending experts to testify at both those hearings, and we’ll report back from them. EPA will also begin accepting public comments soon.
