Top takeaways from the latest IPCC report

By | Published: April 16, 2014

(This post originally appeared on EDF Voices)

Yesterday, the United Nations’ Intergovernmental Panel on Climate Change (IPCC) released its last report in a three-part series that makes up the fifth assessment report (AR5) on the latest data and research on climate change. The reports have been issued approximately every five years since 1990.

This latest round of reports began in September 2013 with anupdate on the latest science behind climate change (known as Working Group I). Last month, the second report was released and discussed climate change impacts, adaptation, and vulnerability already observed and projected in the future (known as Working Group II).

The new report released yesterday (known as Working Group III) discusses actions to limit the magnitude and rate of climate change, termed mitigation. Over 400 experts from over 50 countries were involved in the development of the report, which was accepted by representatives from 195 nations.

Here are 5 key findings from the new lPCC report:

1. Global emissions of heat-trapping gases from human activities have continued to rise. Emissions are dominated by carbon dioxide (mainly from fossil fuel combustion and industrial processes), which account for 78% of total greenhouse gas emissions from 1970 to 2010 (when other gas emissions are weighted to incorporate warming capability relative to CO2). Greenhouse gas emissions have grown more rapidly between 2000 and 2010 than in previous decades despite a recent push to limit emissions; economic and population growth are driving these increases and continue to outgrow emission savings from energy improvements.

2. Action to limit the magnitude and rate of climate change is needed immediately. Climate conditions are changing rapidly as shown in Working Group I, and the impacts to society and ecosystems are unequivocal, consequential, and increasing as shown in Working Group II. Scenarios to limit warming to 2ºC (3.6ºF) relative to preindustrial levels require drastic cuts in greenhouse gas emissions by mid-century through large-scale changes in energy systems and land-use practices. The longer we delay action, the more expensive it will be.

3. It is key to reduce energy demand, deploy low-carbon technologies, and better conserve and manage forestry and agriculture. There is a range of technological and behavioral options for sustainable climate actions; nearly one thousand scenarios were analyzed in the report.

  • Near-term reductions in energy demand through efficiency enhancements in transport, buildings, and industry sectors are cost-effective, provide flexibility for decarbonizing in the energy supply sector, reduce risks in energy supply, and prevent future lock-in to carbon-intensive infrastructures.
  • Behavioral and lifestyle changes—such as lower energy use in households, buying longer-lasting products, changing dietary habits, and reducing food waste—can considerably lower greenhouse gas emissions alongside technological and structural changes. Further development and implementation of low-carbon energy and/or carbon removal technologies is important.
  • Renewable energy technologies—such as wind, hydro, and solar power—have finally achieved a level of maturity to enable large-scale deployment. However, steep challenges exist, including varying costs, regional circumstances, and the existing background energy system.
  • The best climate actions for forestry include afforestation, sustainable forest management, and reducing deforestation. For agriculture, best practices include cropland and grazing land management, and restoration of organic soil. Sustainable agriculture practices can also promote resilience to climate change impacts.

4. Effective actions will only be achieved by international cooperation. Climate change is a global problem because most heat-trapping gases accumulate over time and mix globally. Therefore, emissions by an individual, community, company, or country, affect the globe. The number of institutions for international cooperation is increasing, and sharing knowledge and technologies with other nations speeds up finding solutions. The issue is complicated by the fact that different countries’ past and future contributions to atmospheric greenhouse gas levels are different, as is their capacities to implement actions to limit climate change and build resilience.

5. Co-benefits strengthen the basis for undertaking climate action. Measures to limit energy demand (efficiency, conservation, and behavioral changes) and renewable alternatives can reduce the risk of energy supply, improve public health and the environment by limiting pollution, induce local and sectoral employment gains, support good business practices, improve security of energy supply at the national level, and eradicate poverty. Adverse side effects, such as reduced revenue from coal and oil exporters, can be to a certain extent avoided by the development of carbon capture and storage technologies.

The IPCC will conclude the AR5 in October 2014 with a final report that summarizes the three-part series, recapping the major findings of the physical science of climate change, its effects on society and ecosystems, and actions to avert catastrophic climate change.

There are many ways YOU can help promote climate actions, such as supporting the U.S. to continue its emission-reducing efforts like the EPA’s power plant standards.

6 key insights from the latest IPCC climate report

By | Published: April 1, 2014

(This post originally appeared on EDF Voices)

Since 1990, the United Nations’ Intergovernmental Panel on Climate Change (IPCC) has released a series of reports that assess the latest data and research on climate change.

The reports are issued approximately every five years. In September 2013, the IPCC issued its newest round of reports by sharing the latest science, concluding with more confidence than ever that humans are responsible and that weather will likely get even more extreme, along with many other key findings.

The newest report, released today, looks at impacts, adaptation and vulnerability. Next month comes the thirdreport in the 3-part series that makes up the IPCC’s 5thAssessment Report (IPCC AR5); it focuses on mitigation—that is, actions to limit the magnitude and rate of climate change.

Over 600 scientists and experts from at least 70 countries were involved in writing this latest installment of the IPCC AR5, which is referred to as Working Group II. Representatives from 195 nations had to approve of the Summary for Policymakers document line-by-line.

The report’s content focuses on three topics:

  • Impacts: effects of climate change on people, society, and ecosystems
  • Adaptation: actions to limit our risks to climate change
  • Vulnerability: the susceptibility of the human and natural worlds to climate change

Here are six key findings from the new IPCC report:

1.       Climate change is now everywhere. Impacts have been found on every continent and across all oceans. Both human and natural systems are experiencing the far-reaching and ever-growing effects: water resources are shrinking; terrestrial, freshwater, and marine species have changed their ways of life; major crop yields have decreased; and heat-related deaths have risen.

2.       Humans and ecosystems are both vulnerable. Climate events such as heat waves, droughts, floods, and wildfires alter ecosystems; disrupt food production and water supply; damage infrastructure and settlements; cause sickness and mortality; and adversely affect mental health and human livelihood. However, people who are socially, economically, culturally, politically, institutionally, or otherwise marginalized are especially vulnerable.

3.       Food security, water resources, human health, ecosystems, and the economy are all at stake. While the degree of risks varies based on climatic and non-climatic factors, scientists are confident that human and natural systems are threatened with continued warming. ‘Runaway’ warming (a global temperature increase of 4˚C (7.2˚F) above preindustrial levels—we are currently at 0.86˚C (1.5˚F)) could make normal activities like growing food or working outdoors impossible in many regions.

4.       Many global risks of climate change are concentrated in urban areas. Heat stress, extreme precipitation, inland and coastal flooding, landslides, air pollution, drought, and water scarcity pose risks in urban areas for people, assets, economies, and ecosystems.

5.       Building resilience is critical to limiting risks… Even the most rigorous mitigation tactics still won’t eliminate some additional warming. The upshot: there are countless opportunities for local, state, and national governments to plan and implement adaptation efforts, and also opportunities for public and private engagements. The down side: several barriers to adaptation still exist (such as legal and financial constraints), and if heat-trapping gas emissions remain unabated and the Earth warms by 4˚C (7.2˚F), the impacts may grow larger than our capacity to adapt.

6.       …but cutting heat-trapping gas emissions is essential. Delaying mitigation actions will likely reduce options for climate-resilient pathways, and make them much less affordable. Fortunately, we can solve two problems at once; examples of actions that build resilience and cut gas emissions include: improved energy efficiency and cleaner energy sources; reduced energy and water consumption in urban areas through greening cities and recycling water; sustainable agriculture and forestry; and protection of ecosystems for carbon storage and other ecosystem services.

Energy Efficiency and Carbon Pollution Standards: Double Dividends for Climate and Consumers

By | Bio | Published: March 27, 2014

The U.S. Environmental Protection Agency (EPA) has embarked on a vital effort — accompanied by extensive outreach to states, power companies, environmental organizations, and other stakeholders, including you — to establish the nation’s first limits on carbon pollution from fossil fuel-fired power plants.

EPA was directed to take this critical step for public health and the environment in the President’s Climate Action Plan that was released last summer. Protective and well-designed Carbon Pollution Standards will provide important benefits for all Americans.

Fossil fuel-fired power plants emit 40 percent of the nation’s carbon pollution, as well as significant amounts of mercury, acid gases, and pollutants that contribute to smog and particulates.

That’s why it is critical to get these rules right, and to mobilize common sense solutions proven in red and blue states alike in reducing carbon pollution from the power sector.

Of all the available ways to reduce carbon pollution, one of the most cost-effective and time-tested approaches is to reduce demand for fossil fuel electricity through end-use energy efficiency (EE).

EE measures encompass countless improvements, large and small, in the ways we use electricity in our offices, factories, and homes. All of those improvements can add up to big savings, not only in our monthly energy bills but in the total amount of fossil generation needed to power our society.

Dozens of states and power companies are already investing heavily in EE, and have built up decades of experience in measuring and verifying the many benefits it can yield for consumers and for the environment.

Incredible Potential to Cut Emissions and Save Money by Reducing Wasted Electricity

States and power companies around the country have been implementing EE programs for decades, and have increased their efforts in recent years as experience with the benefits of EE has grown.

26 states in diverse regions of the country, from Arizona and Colorado in the Southwest to industrial Midwest states like Ohio and Illinois, now have “energy efficiency resource standards” or similar policies that require utilities to achieve a certain amount of energy savings each year.

State spending on EE programs increased by 28 percent between 2010 and 2012.

As EE policies and investments have grown, so have energy savings.

In 2011, state EE programs saved a total of 22.9 million megawatt-hours — roughly equivalent to the entire annual output of seven 500 megawatt coal-fired power plants.

These savings increased 22 percent since 2010 and, importantly, count only those savings achieved in the first year these EE measures are in place.

Because most EE measures continue to yield energy savings years or even decades after they are installed, the cumulative savings from these state EE programs are much larger.

A recent study by the American Council for an Energy Efficient Economy found that EE programs and policies are a key reason why residential and commercial electricity demand has remained stable since 2007.

As impressive as these developments are, they only scratch the surface of what could be achieved if we were to fully unlock the potential for EE to save energy and reduce emissions.

An exhaustive 2009 analysis by McKinsey & Company, for example, found that rigorous investment in cost-effective EE could reduce the country’s total energy consumption by 23 percent in 2020.

Energy savings on this scale would yield massive emission reductions — about 700 million metric tons of carbon dioxidein 2020 alone (more than 30 percent of power sector emissions today) – and at a cost per kilowatt-hour saved that is about 85 percent less than the average retail price of electricity.

The report also estimated that realizing these energy savings would create about 600,000 to 900,000 jobs through 2020.

Other national and regional studies have similarly found that EE represents a tremendous “win-win” opportunity for our climate, for families and consumers, and for the economy as a whole.

In 2012, for example, the Southwest Energy Efficiency Project (SWEEP) issued a report focusing on the potential benefits of scaling-up EE programs in six Southwestern states (Arizona, Colorado, Nevada, New Mexico, Utah, and Wyoming).

Based on the track record of “best practice” EE programs around the country, SWEEP found that these six states could reduce their electricity demand in 2020 by more than 20 percent while achieving net benefits of about $20 billion – amounting to $2,650 for every household in the region (largely in the form of lower energy bills).

Investments in EE at this scale would also create about 30,000 additional jobs in the region by 2020, and increase wages and salaries by more than $1 billion.

At the same time, these EE measures would reduce carbon pollution by more than 30 million metric tons in 2020, (a 16% reduction relative to expected emissions in 2020), while also reducing thousands of tons of pollutants that contribute to smog, acid rain, and harmful particulate pollution.

EE and the Carbon Pollution Standards

If you’ve read my colleague Megan Ceronsky’s earlier blog, you’ve already heard about section 111(d) of the Clean Air Act.

That section provides bedrock authority for EPA to issue Carbon Pollution Standards for existing power plants.  It also provides a broad, flexible framework for states and companies to deploy EE and other flexible approaches to reducing carbon pollution from the power sector.

Under section 111(d), EPA and the states will work together to reduce emissions from existing power plants.  EPA will issue “emission guidelines” that identify the “best system of emission reduction” for carbon pollution from existing power plants and the emission reductions achievable using that system.  The states then have the responsibility to develop plans that implement standards consistent with those guidelines.

Just a few weeks ago, Kate Konschnik, Policy Director of the Environmental Law Program at Harvard Law School, released a report that makes a strong legal case for considering EE as part of the “best system of emission reduction” that underpins EPA’s emission guidelines.

As Konschnik argues, the Clean Air Act grants EPA broad authority to consider flexible measures such as EE as a part of the best system of emission reduction for carbon pollution:

[B]ecause it is adequately demonstrated and cost-effective, imposes minimal environmental costs, and reduces overall energy requirements.

Moreover, as Konschnik points out, methods for quantifying and verifying EE-related energy savings and emission reductions are well-developed.

Over the last two decades, at least 35 states and two regional transmission organizations have adopted protocols for measuring and verifying energy savings from EE projects. These savings are now widely used as the basis for critical regulatory proceedings and market functions, including establishing utility rates, compensating EE in regional capacity markets, and carrying out long-term regional resource planning.

In addition, EPA has already allowed several states to credit emission reductions resulting from EE and renewable energy towards compliance with national air quality standards. EPA has also issued detailed guidance to the states on analytical approaches and tools that could be used for future programs.

Ensuring Smooth Implementation of EE in the Carbon Pollution Standards

Under traditional emissions trading programs such as the Regional Greenhouse Gas Initiative (RGGI) or California’s cap-and-trade system, the emission reduction benefits of EE are readily observed as emissions from power plants drop.

Under these programs, no separate system for tracking emission reductions from EE is necessary.  As a recent report by RGGI confirms, these programs are also funding significant investments in EE programs that have already helped 815,000 families.

However, some states may choose to directly incentivize EE through policies that credit individual projects and programs for their impacts on energy savings and emissions.

For this reason, EDF has worked with experts in the field to study how measurement and verification for such EE crediting systems could work in a way that is environmentally rigorous and administratively streamlined, and that builds on extensive state and regional experience with existing EE programs.

We recently submitted a report to EPA, developed by the Analysis Group, that lays out one possible framework for ensuring both desirable outcomes:

  • Rigorous measurement and verification of EE projects, and
  • Consistent methods for determining emission reductions that are attributable to EE projects

This framework recognizes the diverse approaches to measurement and verification of EE that are in use around the country. But in developing this framework, we were also struck by the significant progress that a number of organizations have made in developing best practices and consensus protocols for evaluating EE projects.

One example is the Department of Energy’s Uniform Methods Project (UMP), which has organized a multi-stakeholder process to develop rigorous yet streamlined measurement and verification protocols for different types of EE projects.

To date, UMP has released protocols addressing seven major EE project types and five “cross-cutting” evaluation issues. Eight more protocols are expected to be finalized in the coming months.

Other notable efforts to develop and encourage best practices in the field include:

EE: Ready for Prime Time

EE represents a historic opportunity to achieve extensive reductions in emissions of carbon pollution and other power sector pollutants that directly harm public health and the environment.

In many cases, EE measures will actually save families and businesses money over time and help strengthen the economy.

Decades of state and utility experience in designing and implementing EE programs have demonstrated that the benefits of EE are real, and that the policies and tools needed to incentivize EE and measure its effects are available.

EPA should fully mobilize the potential of EE by exercising its authority to consider EE in the design of the Carbon Pollution Standards, and by providing guidance to the states to facilitate the inclusion of EE in state plans implementing those standards.

The Supreme Court and Climate Pollution: What is – and is not — at stake

By | Bio | Published: February 24, 2014

(This post originally appeared on EDF Voices)

Today, the Supreme Court will hear oral argument in a case challenging EPA’s interpretation that the Clean Air Act permit program requiring new and rebuilt industrial sources to deploy leading pollution control technology for each pollutant subject to regulation under the Act applies to greenhouse gases, just as these requirements have limited other airborne contaminants for over three decades.

The case is Utility Air Regulatory Group v. EPA (No. 12-1146). 

What’s at stake: Innovation in Addressing Climate Pollution and Clearing the Air about Climate Obstructionism

This case is remarkable for what is not at stake, as well as for what is.

While the Supreme Court is considering only a single legal question of the numerous issues that were raised, this case has important implications.

Exempting climate pollution from these specific provisions of the Clean Air Act would harm innovation, because they were carefully designed by Congress to spur the development of new pollution prevention and control techniques for industrial sources. Putting a stop to these legislatively-crafted incentives to innovation in precisely the area where we so urgently need innovation – in addressing climate-destabilizing pollution — would be a damaging loss and risks “locking in” new high emitting and long lived industrial infrastructure. Such an exemption for climate pollution is patently contrary to Congress’s specific command, in the statutory provisions at issue here, that these innovation-spurring requirements apply to “each pollutant subject to regulation under the Act”.

Climate obstructionists will undoubtedly twist the meaning of the case to suggest broader implications, despite the court's decision to review only one narrow question. While the Administration is judiciously carrying out its responsibilities under the Clean Air Act to address climate pollution – in accordance with the authority that was twice affirmed by the United States Supreme Court — climate obstructionists will use this case to sow havoc and attack the U.S. Environmental Protection Agency. Indeed, these forces have already attacked EPA by unsuccessfully litigating virtually every aspect of EPA’s first generation climate protections in court over a span of many years. Unfortunately, they will continue to attack EPA in the public square invoking the polarizing rhetoric that most Americans associate with divisive Beltway politics – not real world solutions.

What is not at stake in this case is the EPA’s determination that six greenhouse gases –carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride –endanger the health and welfare of current and future generations. This is the bedrock for EPA’s manifest authority to adopt climate protections for cleaner cars and cleaner freight trucks, for reducing the potent methane leaked and vented from oil and gas development activities in the same way that Colorado has adopted methane emissions standards, and for cutting the massive carbon pollution from power plants — the nation’s single largest source of carbon pollution and one of the largest in the world.

The history behind the case

For the past four years, big polluters and litigants such as the Attorney General of Texas have been suing the U.S. Environmental Protection Agency over all aspects of EPA’s climate protections for America – including the science-based endangerment finding, and the historic Clean Cars Standards that are saving Americans money at the gas pump while strengthening our nation’s energy security and reducing pollution. By contrast, the U.S. Automakers have consistently supported the clean car standards.

These dozens of lawsuits were considered together by the U.S. Court of Appeals for the D.C. Circuit – which upheld EPA’s climate protections and rejected the legal challenges. In 2012, a three Judge panel of that court held that EPA’s interpretation of the Clean Air Act was “unambiguously correct.” Then-Chief Judge David Sentelle, appointed to the Court by President Ronald Regan, was a member of the three Judge panel that unanimously affirmed EPA’s action.

Opponents filed numerous petitions seeking review by the Supreme Court, which refused to entertain most of their challenges.

Instead, the Court granted review of a single question – whether, under the terms of the Clean Air Act, EPA’s regulation of climate pollution from cars triggered the requirement for pre-construction permits limiting the climate pollution discharged by large, new and rebuilt industrial sources of that pollution in the same way these requirements have applied to other air pollutants from these sources for over 35 years.

Bottom line

We need all available safeguards under the Clean Air Act to address the urgent challenge of climate change – including the advanced pollution control measures required as an essential protection in construction permits for large industrial sources. These measures are vital if we hope to minimize industrial climate pollution.

Further, one of the principal legal theories being advanced by petitioners would have adverse consequences for EPA’s long-standing interpretation of the law – spanning the Presidencies of Ronald Regan, George H.W. Bush and George W. Bush – that has expansively applied the protections of the Clean Air Act’s pre-construction review permit program to all regulated air pollutants. This line of attack, designed to narrow the air pollutants subject to these limits, would call into question the application of the program to pollutants such as hydrogen sulfide, fluorides and sulfuric acid mist.

Finally, we need to tell the truth to the public, to policymakers and to the highest Court in the land that EPA is judiciously carrying out its responsibilities under the nation’s clean air laws to protect human health and the environment from climate pollution. We must take a stand against the sharply polarizing rhetorical excess leveled at EPA. For the real world solutions that have won far reaching support, look no further than the cleaner cars on the road today that are strengthening our energy security, saving families hard earned money at the gas pump, and cutting carbon pollution.

This is why EDF will be at the Supreme Court today.

Editor’s Note: Environmental Defense Fund is a party to the case before the Supreme Court and participated in the presentation of oral arguments when the case was before the U.S. Court of Appeals for the D.C. Circuit.  A coalition of states and NGO allies are also vigorously defending these clean air protections against legal attack — including California, Connecticut, Delaware, Illinois, Iowa, Maine, Maryland, Massachusetts, New Hampshire, New Mexico, New York, Oregon, Rhode Island, Vermont, Washington, and the city of New York.

We’re on the Road to Cleaner, More Fuel-Efficient Trucks

By | Published: February 18, 2014

America started down the road toward cleaner, more fuel-efficient freight trucks today.

President Obama, joined by leading freight truck manufacturers and major fleet owners, announced plans to draft a second generation of fuel efficiency and greenhouse gas standards for America’s heavy-duty trucks.

The new standards will build on the successful first round, which are yielding far-reaching benefits for America’s security, economy and environment.

As the President said in his 2014 State of the Union Address:

We’ve partnered with businesses, builders, and local communities to reduce the energy we consume. When we rescued our automakers, for example, we worked with them to set higher fuel efficiency standards for our cars.  In the coming months, I'll build on that success by setting new standards for our trucks, so we can keep driving down oil imports and what we pay at the pump.

Opportunity

Climate pollution from our nation’s freight trucks is projected to increase by more than 130 million tons between now and 2040 – the largest increase in emissions from any single end-use, according to the Energy Information Administration.

Recent analyses, however, indicate that rigorous second generation fuel efficiency and greenhouse gas standards for new freight trucks can cost-effectively reduce this climate pollution, improve our nation’s energy security, and save truckers money.

Consider this:

  • By 2025, strong second generation truck standards could reduce fuel consumption by up to 40 percent compared to 2010. That’s more than 800,000 barrels of oil savings per day beyond what’s achieved by current standards.
  • Most technologies needed to achieve this reduction have payback periods of three years or less.

Making our nation’s fleet of trucks more efficient is also good for consumers.

Improving efficiency means cutting the costs associated with transporting goods. That means companies can sell those goods for less, which in turn means that American families will save money.

A recent report by the Consumer Federation of America found:

  • Net savings of $250 to consumers, rising to $400 per household in 2035 as fuel prices and transportation services increase.

Solutions

Cost-effective, made-in-America solutions are available to help achieve these important environmental, economic and energy security benefits.

Rigorous second-generation clean trucks standards can help deploy these made-in-America technologies.

Strong standards are also critical to spur investment and innovation leading to the next generation of clean truck solutions.

For instance:

Just yesterday, Walmart unveiled “Jetson,”a prototype tractor-trailer powered by a revolutionary combination of a microturbine, battery storage, and electric motor, with advanced aerodynamics and a carbon-fiber trailer.

Broad-Based Support

These common sense solutions have resulted in broad support.

Many of the same companies that stood with the President today also collaborated on the first generation clean trucks standards.

Among those supporting the President today included the nation’s major manufacturers and fleets such as Conway, Cummins, Eaton, Wabash National, Waste Management and the American Trucking Association.

Proven Success

These second generation clean truck standards build on a foundation of success — including first and second generation clean cars standards and first generation clean trucks standards.

Manufacturers are meeting these standards in advance of compliance deadlines, doing so for lower costs, and delivering substantial, real-world benefits.

For example, here are some compelling achievements by passenger cars and trucks as a result of efficiency standards:

  • Since October 2007, per driver greenhouse gas emissions in the U.S. have dropped by 20 percent, according to the University of Michigan’s Eco-Driving Index.
  • EPA estimates that between model years 2004 and 2012, average carbon dioxide emissions from cars decreased by 18 percent, and fuel economy increased by 22 percent.
  • 28 percent of projected model year 2013 vehicle production already meets the model year 2016 carbon dioxide emissions targets, and about 5 percent of projected 2013 production could meet the 2025 carbon dioxide emissions targets, according to EPA’s fuel economy trends report.

The cleaner cars and freight trucks being made in America today show that when our nation works together we can achieve lasting progress for our economy and our environment.

Environmental Defense Fund stands ready today to work with President Obama, freight truck and trailer manufacturers, and fleet owners on common sense policies to advance and secure the transformative cleaner freight trucks of tomorrow.

Powerful Testimonies at EPA Hearing on Carbon Pollution Standards for Power Plants

By | Bio | Published: February 10, 2014

If you were busy watching the Winter Olympics, you may have missed another important–if slightly smaller–event that happened last Thursday:

The U.S. Environmental Protection Agency (EPA) held a hearing in Washington, D.C. on the proposed carbon pollution standards for new power plants.

U.S. power plants are one of the largest sources of carbon pollution in the world. Carbon pollution is the main reason for climate change.

EPA’s proposed standards will set the first-ever national limits on carbon pollution from new fossil fuel power plants.

I had the privilege of testifying on behalf of EDF and its 750,000 members.

It was uplifting to hear testimony from so many diverse groups in support of these historic proposed standards.

Among those testifying were:

  • U.S. Senator Sheldon Whitehouse of Rhode Island
  • Moms Clean Air Force, on behalf of hundreds of thousands of moms across America
  • Public health groups
  • Environmental justice groups
  • Veterans and national security groups
  • Groups representing clean energy companies
  • Latino groups
  • Faith groups

and many more …

But climate change is an issue that threatens communities and families across America.

That’s why it was especially touching to hear the personal stories of how climate change impacts people, including one woman from Virginia who testified about raising a daughter with asthma, about the financial impacts of the disease–and about how the costs of pollution are not borne by the emitters, but by the public–and by families like hers.

Carbon pollution is a problem that we can fix.

Consider these facts:

  • Clean energy continues to grow, and it is clear that America can generate affordable, clean electricity.
  • Wind generation increased by more than 40 percent in the United States between 2011 and October of 2013.
  • In April of 2013, the United States had a record month for wind power with generation of more than 17,000 gigawatt hours.
  • In 2012, rooftop solar panels cost approximately one percent of what they did 35 years ago.
  • Since 2008, as the cost of a solar module dropped from $3.80 per watt to 80 cents per watt, solar deployment has jumped by about 10 times.
  • U.S. solar jobs grew 20 percent last year. The industry now supports more than 140,000 jobs.
  • Renewable energy is expected to account for 28 percent of the growth in electricity generation from 2012 to 2040.

At the hearing, some opponents of EPA’s common-sense standards testified, representing groups like the American Petroleum Institute and the American Coal Council.

They repeated claims we have heard time and again about clean air standards costing too much or technology not being available.

We have heard similar claims in the past—claims that were subsequently disproved—about scrubbers and mercury controls.

EPA has found that carbon pollution controls, like carbon capture and storage, are adequately demonstrated for new coal-fired power plants—and that finding is based on an extensive body of technical information.

It is clear from the more than four million people who have weighed in with EPA in support of these standards that many Americans are ready for a clean energy future, and believe it is imperative that we address the largest source of carbon pollution in our country.

You can help the fight to limit the carbon pollution from power plants by urging EPA to adopt strong standards. You can submit comments to EPA through our EDF website.

Reality check: Society pays for carbon pollution and that's no benefit

By | Bio | Published: February 4, 2014

This open letter, co-authored by Jeremy Proville and first published on EDF Voices, was written in response to a New York Times article citing Dr. Roger Bezdek’s report on “The Social Costs of Carbon? No, The Social Benefits of Carbon.”

Dear Dr. Bezdek,

After seeing so many peer-reviewed studies documenting the costs of carbon pollution, it’s refreshing to encounter some out-of-the-box thinking to the contrary. You had us with your assertion that: “Even the most conservative estimates peg the social benefit of carbon-based fuels as 50 times greater than its supposed social cost.” We almost quit our jobs and joined the coal lobby. Who wouldn’t want to work so selflessly for the greater good?

Then we looked at the rest of your report. Your central argument seems to be: Cheap fuels emit carbon; cheap fuels are good; so, by the transitive property of Huh?!, carbon is good. Pithy arguments are fine, but circular ones aren’t.

First off, cheap fuels are good. Or more precisely, cheap and efficient energy services are good. (Energy efficiency, of course, is good, too. Inefficiency clearly isn’t.) Cheap energy services have done wonders for the United States and the world, and they are still doing so. No one here is anti-energy; we are against ruining our planet while we are at it.

The high cost of cheap energy

Yes, the sadly still dominant fuels—by far not all—emit carbon pollution. Coal emits the most. Which is why the cost to society is so staggering. Forget carbon for a moment. Mercury poisoning from U.S. power plants alone causes everything from heart attacks to asthma to inhibiting cognitive development in children. The latter alone is responsible for estimated costs of $1.3 billion per year by knocking off IQ points in kids. All told, coal costs America $330 to 500 billion per year.

Put differently, every ton of coal—like every barrel of oil—causes more in external damages than it adds value to GDP. The costs faced by those deciding how much fossil fuel to burn are much lower than the costs faced by society.

None of that means we shouldn’t burn any coal or oil. It simply means those who profit from producing these fuels shouldn’t get a free ride on the taxpayer. Conservative estimates indicate that carbon pollution costs society about $40 per ton. And yes, that’s a cost.

Socializing the costs is not an option

As someone with a Ph.D. in economics, Dr. Bezdek, you surely understand the difference between private benefits and social costs. No one would be burning any coal if there weren’t benefits to doing so. However, the “social benefits” you ascribe to coal are anything but; in reality they are private, in the best sense of the word.

If you are the one burning coal, you benefit. If you are the one using electricity produced by burning coal, you benefit, too. To be clear, these are benefits. No one disputes that. It’s how markets work.

But markets also fail in a very important way. The bystanders who are breathing the polluted air are paying dearly. The costs, if you will, are socialized. Society—all of us—pays for them. That includes those who seemingly benefit from burning coal in the first place.

Your claim that what you call “social benefits” of coal dwarf the costs is wrong in theory and practice. In theory, because they are private benefits. As a matter of practice because these (private) benefits are very much included in the calculations that give us the social costs of coal. What you call out as the social benefits of coal use are already captured by these calculations. They are part of economic output.

Our indicators for GDP do a pretty good job capturing all these private benefits of economic activity. Where they fail is with the social costs. Hence the need to calculate the social cost of carbon pollution in the first place.

So far so bad. Then there’s this:

Plants need carbon dioxide to grow, just not too much of it

In your report, you also discuss what you call the benefits of increases in agricultural yields from the well-known carbon dioxide fertilization effect. It may surprise you to hear that the models used to calculate the cost of carbon include that effect. It turns out, they, too, in part base it on outdated science that ought to be updated.

But their science still isn’t as old as yours. For some reason, you only chose to include papers on the fertilization effect published between 1902 and 1997 (save one that is tangentially related).

For an updated perspective, try one of the most comprehensive economic analysis to date, pointing to large aggregate losses. Or try this Science article, casting serious doubt on any claims that carbon dioxide fertilization could offset the impacts on agricultural yields from climate change.

Farmers and ranchers already have a lot to endure from the effects of climate change. There’s no need to make it worse with false, outdated promises.

Coal lobby speaks, industry no longer listens

It’s for all these reasons that, to borrow the apt title to the otherwise excellent New York Times story that ran your quote: “Industry Awakens to Threat of Climate Change”. And it’s precisely why the U.S. government calculates the social cost of carbon pollution. Yes, sadly, it’s a cost, not a benefit.

To our readers: Want to get involved? The White House has issued a formal call for public comments on the way the cost of carbon figure is calculated, open throughFebruary 26. You can help by reminding our leaders in Washington that we need strong, science-based climate policies.

New Truck Efficiency Standards Are Great News for American Innovation

By | Bio | Published: January 31, 2014

We've partnered with businesses, builders, and local communities to reduce the energy we consume. When we rescued our automakers, for example, we worked with them to set higher fuel efficiency standards for our cars. In the coming months, I'll build on that success by setting new standards for our trucks, so we can keep driving down oil imports and what we pay at the pump.

- 2014 State of the Union Address

First, here’s the bad news:

Climate pollution from America’s heavy trucks is projected to increase by more than 130 million tons between now and 2040. That’s expected to be the largest increase in emissions from any single source.

The average new heavy-duty diesel truck sold last year got slightly less than six miles per gallon.

Most of these trucks travel upwards of 120,000 miles and burn more than $80,000 worth of fuel per year.

This inefficiency has real costs for our economy. We import millions of barrels of oil to fuel heavy-duty trucks. Businesses, both small and large, spend billions on the fuel needed to move freight. You and I pay for this too, when we buy those products.

Now here’s the good news:

It doesn’t have to be this way. We have the tools today that we need to change this.

We have the technology to decrease freight truck emissions. We can cut 20 percent off our current trajectories by 2030, and go much further by 2040.

In fact, a recent analysis by the American Council for an Energy-Efficient Economy found that it’s realistic to expect new trucks to achieve something approaching a 40 percent fuel consumption reduction, compared to 2010 trucks, within the next decade,

Well-designed federal standards can foster the innovation necessary to bring more efficient and lower emitting trucks to market. Manufacturers need to be confident in market demand in order to develop and launch efficiency improvements. Scaled production can drive down costs, further enhancing the payback truck fleets will experience through lower fuel bills.

EDF has set out a blueprint for rigorous greenhouse gas and fuel efficiency standards. Through smart, well designed policies and American innovation, we can cut climate pollution and save fuel costs while strengthening our security and winning the race to deploy clean energy technologies in the global marketplace.

Many companies already have developed — and are bringing to market — the tools we need to meet a strong standard.

Examples include:

Eaton, a manufacturer of truck transmissions — they’ve launched a powertrain package that can improve fuel efficiency by up to six percent.

Cummins, Inc. and Peterbilt Motors Co., which build truck engines and manufacture trucks, respectively – they partnered last year to build a truck that uses 50 percent less fuel than typical long-haul tractors, according to an article in the Indianapolis Star. It averaged 9.9 miles a gallon in road tests. They did this through a suite of improvements; including capturing otherwise wasted thermal energy.

Smart Truck Systems, a supplier of aerodynamic products to the trucking industry – they have a product that can cut fuel consumption from tractor-trailer combination trucks by over 10 percent through advanced aerodynamics.

Also available to us:

To understand the positive economic potential of adopting strong truck fuel efficiency standards, we only need to look back to the start of this month.

On January 1st, our nation’s biggest trucks became subject – for the first time ever – to fuel efficiency standards. These standards cover trucks from large pick-ups to tractor-trailers. They will cut climate pollution by almost 300 million tons while saving truck operators $50 billion.

For combination tractor-trailer trucks, these standards will cut annual fuel costs by more than $18,000 at today’s prices. The fuel savings will pay back the increase in upfront costs in less than five months.

Companies that rely on trucking to move goods stand to benefit significantly too. These companies will see a decrease of around eleven cents in the total cost-per-mile to move freight. Across their supply chain, large freight shippers will save millions of dollars each year because of this rule.

These are real savings that businesses, big and small, are starting to see in their bottom line today.

These first generation standards were created with the broad support of the trucking industry and many other key stakeholders. Among the diverse groups that supported the standards were the American Trucking Association, Engine Manufacturers Association and the Truck Manufacturers Association, the United Auto Workers — and of course EDF.

But this is just the beginning.

With the right political and commercial will, we can build on the partnership created during the development of the current standards to find common ground on the next phase of truck efficiency rules.

We can do this in a way that enables American businesses to thrive, cuts the need for imported oil by hundreds of millions of barrels a year, and slashes climate pollution by more than 100 million tons a year.

That’s why it was great to hear President Obama’s call to action in the State of the Union Address about the next phase of truck standards. We already knew that we could do it – now it looks like we will.

The Silver Bullet Of Climate Change Policy

By | Bio | Published: January 24, 2014

(This post originally appeared on Forbes)

By Bob Litterman and Gernot Wagner

Whenever the conversation turns to climate change, someone is sure to opine that there’s no silver bullet. The issue is simply too complex to have one solution. When you focus on all the changes that need to occur to reduce greenhouse gas emissions globally it seems like a multifaceted approach is the only way forward.

Most of the world’s vexing problems share that feature. Mideast peace, nuclear non-proliferation, Eurozone stability, and plenty of other national security problems have no single right plan of attack. Some past plans might have brought us tantalizingly close to a seeming solution, but then reality started interfering once again, reconfirming the complexity of it all.

Climate change must surely be in that category. No single country, no single technology, no single approach can seemingly solve this one for us once and for all. Picking a single technology will almost inevitably end in some form of disappointment. Bureaucrats, the saying goes, ought not to try to pick winners. Leave that to venture capitalists for whom failure is a way of life. For every Apple and Facebook, there are dozens who never make it out of the garage. And clean technology doesn’t yet even have a single Apple and Facebook as the standout approach revolutionizing the field.

It turns out, though, that how you frame the issue is crucial. If you think like an engineer there are dozens of challenges. If you think like an economist, there is one. It’s guiding the ‘invisible hand’. How can you create the appropriate incentive to decrease the pollution that’s causing climate change? For that, the government need not be in the business of picking winners at all. What it should—and can—do is identify the loser that’s been clear for decades: greenhouse gas pollution. And the solution is equally clear: create incentives to reduce emissions by pricing it. If we make this one change, most other actions that are needed will follow.

That’s what the European Union has done by capping carbon emissions from its energy sector, including large industrials, covering almost half of total carbon emissions. That’s what California is doing with over 80 percent of its total global warming emissions. It’s what China is experimenting with in seven city and regional trials, including in Beijing and Shanghai. All these systems put a price on greenhouse gas pollution.

On the other side of the ledger, there are still much larger incentives to consume fossil fuels in many other countries. The International Energy Agency estimates that global subsidies are well over $500 billion. These subsidies, which incentivize emissions, sadly dwarf the paltry incentives to reduce them. Free marketeers, small government advocates, and others who dislike distorting government subsidies should be appalled at the tax money poured into fossil fuels.

There’s one simple principle that’s been around in economics for so long that no economist worth his or her degree would question the conclusion: increase the price, watch the quantity demanded go down. It’s such a universal truism that economists call it the “Law of Demand.” Generations of graduate students have estimated the effects of price on demand for anything from the generic widget to demand for car miles driven. People may be irrational at times, but one thing that we know for sure is that they respond to incentives.

Everything we know from decades of the study of human behavior would lead us to believe that carbon pollution will go down as the price on emissions increases. The only interesting question is by how much.

The prescription then for anyone seriously concerned about climate change is simple: price carbon to the point where its now unpriced damages are incorporated into the price, and get out of the way. It’s simple. It works. It’s conservative to the core.

It’s also a silver bullet solution if there ever was one.

A Milestone in a Vitally Important Clean Air Act Case Before the Supreme Court

By | Published: January 23, 2014

This week, we saw another milestone in a vitally important Supreme Court case about the Clean Air Act and our environment.

On Tuesday, EDF and a coalition of environmental groups joined with the U.S. Environmental Protection Agency (EPA) and 15 states in filing briefs to defend EPA’s rules requiring new and rebuilt industrial sources to use cost-effective technology to limit climate pollution.

(The states are New York, California, Connecticut, Delaware, Illinois, Iowa, Maine, Maryland, Massachusetts, New Hampshire, New Mexico, Oregon, Rhode Island, Vermont, and Washington, plus the City of New York. You can read all the briefs here.)

In October, the Supreme Court denied review of EPA’s historic endangerment finding and clean cars standards, and granted review of a single question: whether EPA permissibly concluded that the regulation of greenhouse gas emissions from motor vehicles triggered the application of the Clean Air Act’s Prevention of Significant Deterioration (PSD) and Title V permitting programs to sources of greenhouse gases.

The permitting programs at issue – PSD and Title V – ensure that large new industrial sources use modern cost-effective solutions to mitigate climate pollution in the same way they have effectively addressed other pollutants under the nation’s clean air laws, and facilitate compliance with the entire range of Clean Air Act programs.

The Clean Air Act is clear that both programs apply to large sources emitting “any air pollutant,” and EPA’s regulations have required PSD and Title V permits for large sources of air pollutants subject to regulation for decades.

The petitioners in this case and those filing amicus briefs on their behalf, many of whom are tied to a $900 million effort to obstruct progress on climate and clean energy, want to upend these long-standing protections.

In the process, they present readings of the Clean Air Act that would exclude common-sense modern pollution controls for climate pollution — as well as hydrogen sulfide, sulfuric acid mist, and other air pollutants long regulated under our nation’s clean air laws.

The central theme in their arguments? Someday, EPA might apply these clean air protections to too many emissions sources.

So let’s take a look at greenhouse gas permitting over the last three years:

  • As of this writing, approximately 140 permits have been issued nationwide.
  • Permits cover industries ranging from iron and steel plants to cement plants to power plants.
  • Almost all states are handling their own greenhouse gas permitting.

Meanwhile, EPA is carefully considering next steps for greenhouse gas permitting requirements, including options for lowering the number of sources that might require permits in the future.

The next milestones in the case are coming up soon. Reply briefs are expected on February 15, and the Court will hear oral argument on Monday, February 24.

In the meantime, you can read more about the case here.
