EPA’s Authority to Limit Carbon Pollution from Power Plants Is Well Established and Widely Recognized

Gavel_iStock000003633182Medium(This post was written by EDF attorney Megan Ceronsky and legal fellow Peter Heisler)

The bedrock legal authority underlying the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan is broadly recognized — by our nation’s highest court, states, power companies, academic experts and the EPA General Counsel serving during the President George H.W. Bush administration.

Our recent Climate 411 post chronicles the Supreme Court’s decisions affirming EPA’s authority to address carbon pollution from power plants under section 111 of the Clean Air Act.

In Massachusetts v. EPA (2007), the Court held that carbon dioxide is a pollutant under the Clean Air Act.  Then, in AEP v. Connecticut (2011), the Court explicitly recognized EPA’s authority to limit emissions of carbon dioxide from power plants pursuant to section 111, and acknowledged the agency’s ongoing efforts to do so.

Even before AEP was decided, however, legal researchers and academics had identified section 111 as a promising avenue for regulating carbon pollution from power plants and industrial facilities:

  • A 2009 report by the Congressional Research Service found that “Section 111 appears to provide a strong basis for EPA to establish a traditional regulatory approach to controlling greenhouse gas emissions from large stationary sources.”
  • A 2010 paper by Duke University’s Nicholas Institute for Environmental Policy Solutions observed that “[S]ection 111 appears to provide the EPA with the best means to create a system that … implements a cost-effective program that delivers meaningful emissions reductions, is consistent with both the statutory language of the Act and legal precedent, and is politically viable.”
  • A 2011 survey of the academic community found “widespread agreement” that “[section] 111 authorizes the use of many types of flexible approaches” to regulating carbon pollution.

Indeed, states, power companies, and other stakeholders have all recently analyzed and supported EPA’s authority to limit carbon pollution from power plants:

  • Kentucky recognized EPA’s role in setting the benchmark that states will have to meet under section 111.
  • Pennsylvania said that section 111 was the “most appropriate” provision for regulating carbon dioxide emissions from power plants.
  • The nine Northeastern and Mid-Atlantic states participating in the Regional Greenhouse Gas Initiative “recommend[ed] that EPA use its authority under section 111 of the Clean Air Act to ensure significant overall reductions in carbon emissions.”
  • Fifteen states from across the country agreed that “EPA needs to seize [the] opportunity [for pollution reduction] because Section 111(d) standards are to be based on the ‘best system of emission reduction,’” including energy efficiency and renewable energy.
  • The Clean Energy Group, whose members include some of the largest generators of electricity in the country, noted that “EPA has significant discretion under section 111(d) in determining both the appropriate level of the standards for existing power plants, as well as the form of the regulations.”

Environmental law experts have also analyzed and endorsed EPA’s authority to regulate carbon pollution from power plants:

  • UCLA Law Professor Ann Carlson said “[I]t is important to be clear here: the President is required to issue the rules, required by law and by the interpretation of the law by the highest Court in the land.”
  • Harvard Professor Jody Freeman called critics’ claims to the contrary “weak,” explaining that “[t]he record clearly shows that Congress intended to ensure that harmful pollutants from existing power plants could not entirely escape regulation. These emissions qualify for regulation under 111(d) because they are not covered elsewhere in the law and account for nearly 40 percent of the nation’s total emissions of carbon dioxide, the principal driver of global warming.”
  • E. Donald Elliott, EPA General Counsel under President George H.W. Bush, noted that “the Supreme Court and other courts have upheld EPA’s authority to address this issue,” and “[a] system-wide approach provides needed flexibility and reduces costs, as well as encouraging investment in lower-emitting generation. EPA has wisely left the states a lot of discretion rather than mandating specific measures as some had wanted…”
  • Carol Browner, EPA Administrator during the Clinton administration, wrote that “EPA has authority under the 1990 Clean Air Act, an authority affirmed by the U.S. Supreme Court, to set these public health protections against carbon pollution.”

Finally, Leon G. Billings, who was the principal staff author of the Clean Air Act of 1970, shared his personal knowledge of the statute:

Critics of the move say that President Obama is making an end run around Congress, stretching the law to achieve by executive action what he could not accomplish through the legislative branch … This is flat wrong. More than four decades ago, Congress expressed its clear desire to regulate pollution from power plants, in the form of the Clean Air Act. I know, because I worked on the legislation, including the key part of the act — Section 111 — that the Obama administration is using to justify its move.

The legal community broadly recognizes EPA’s authority and obligation to address carbon pollution emitted by power plants. This is perhaps unsurprising, as all these statements simply echo what the Supreme Court has already held — that EPA’s efforts to reduce carbon pollution from power plants are firmly grounded in the law.

The cheapest way to cut climate pollution? Energy efficiency

This blog post was co-authored by Lauren Navarro, California Senior Manager, Clean Energy and Kate Zerrenner, an EDF project manager and expert on energy efficiency and climate change.

On June 2, the U.S. Environmental Protection Agency made a historic announcement that will change how we make, move and use electricity for generations to come.

For the first time in history, the government proposed limits on the amount of carbon pollution American fossil-fueled power plants are allowed to spew into the atmosphere.

There are two clear winners to comply with the plan while maintaining commitment to electric reliability and affordability: energy efficiency and demand response.

We’re already seeing pushback from some of our nation’s big polluter states, such as West Virginia and Texas. But the truth is that while the proposed limits on carbon are strong, they’re also flexible.

In fact, the EPA has laid out a whole menu of options in its Clean Power Plan – from power plant upgrades, to switching from coal to natural gas and adopting more renewable energy resources. States can choose from these and other strategies as they develop their own plans to meet the new standards.

That said, there are two clear winners on the EPA’s menu that offer low-cost options for states that seek to comply with the plan while maintaining their commitment to electric reliability and affordability: energy efficiency and demand response.

Energy efficiency our lowest-hanging fruit

Simply saving energy is the most cost-effective way to reduce demand and carbon pollution from power plants. The cheapest, cleanest and most reliable electricity, after all, is the electricity we don’t use.

The benefits of energy efficiency are vast. It helps people and businesses save money, it boosts job creation (as many as 274,000, one source estimates), and it reduces harmful power plant pollution.

From a utility perspective, energy efficiency improves the reliability of our electric grid and lowers costs for infrastructure maintenance.

Plus, in states such as Texas and California, which face extreme drought, energy efficiency can save scarce water sources. Remember that coal-fired power plants are thirstyand less water is consumed when these plants are used less (or not at all).

Half of the states already have mandatory energy-efficiency targets, so we have the knowledge and experience across the country to advance this undeniably beneficial resource.

Same as taking all cars off road

McKinsey & Co. estimates that by 2020, the United States could reduce its annual energy consumption by 23 percent by adopting energy-efficiency measures. This could save us more than $1 trillion dollars and cut greenhouse gas emissions by more than a gigaton—the equivalent of taking the entire U.S. fleet of passenger vehicles and light trucks off the road.

That’s why Environmental Defense Fund is working with policymakers, investors and utilities throughout the country to understand the full benefits of energy efficiency, and to explore paths for implementation, for when they’re crafting state plans under EPA’s new Clean Power Plan.

Demand response: everyone wins

Demand response is another way to introduce greater efficiency into the nation’s electricity system and help reduce carbon emissions. It’s an invaluable tool that can help conserve electricity when supplies run thin, and to bring more clean energy onto the grid.

On a hot summer day, for example, when electricity demand is high, utilities can ask permission of select customers to lower their thermostats a couple of degrees. In exchange, these customers receive credit on their next electricity bill.

It also helps utility companies better manage stress on the electric grid and it can help them integrate wind, solar and other renewables to replace aging coal-fired power plants.

Demand response relies on people, not power plants, to meet energy demand and reduce carbon pollution from our electricity sector.

Proven strategies

In Southern California, for example, they’re about to replace a large chunk of electric capacity – at least 550 megawatts – from the recently closed San Onofre Nuclear Generation Station with renewable energy, energy storage – and demand response. This will help minimize a need for gas-fired plants and other polluting facilities that might replace the nuclear plant.

Best of all, demand response is more affordable than building new power plants. In fact, if just 50 percent of Southern California Edison’s customers participated in time-of-use rates – a type of demand response program – energy demand would plummet so much that 66 percent of San Onofre’s former generating capacity would no longer be needed.

As a bonus, customers across the territory would also collectively see cost savings of $357 million, a 15-percent decrease.

As a result of smart decisions such as the one involving the San Onofre plant, California’s utility sector’s greenhouse gas emissions have and will continue to decline. This proves that demand response can and should be a core tenet in the nation’s push to diversify its energy mix and cut pollution in order to usher in a clean, sustainable and healthy future.

As EPA Administrator Gina McCarthy noted last week, these clean energy solutions are not new ideas. They’re based on proven technologies and approaches that “are already part of the ongoing story of energy progress in America.”

“We’re not doing cutting-edge work here, folks,” she said. “We are just opening the door to cutting-edge.”

Saving Billions While Cutting Climate Pollution

More fuel efficient, lower emission heavy trucks are good for business, good for consumers, and good for combating climate change. By deploying existing and emerging technologies to improve truck efficiency, the U.S. can save billions in fuel expenses while cutting harmful climate pollutions by millions of tons.

EDF is calling on the Obama Administration to set new fuel efficiency and greenhouse gas standards for heavy trucks that cut fuel consumption by 40 percent compared to 2010 levels. These standards would apply for freight trucks and heavy-duty work trucks, such as box delivery trucks, bucket trucks, beverage delivery trucks and refuse trucks.

Analysis by leading environmental and energy efficiency advocates, including EDF, demonstrates that bold heavy truck standards are technically feasible and will be effective in cutting oil consumption and climate pollution.

Strong standards will be good for American business and consumers too.

EDF and Ceres examined how strong standards would affect the cost of moving freight by trucks. The results are unequivocal — strong standards will save companies money.

For example, an owner of a new tractor-trailer unit stands to save between $21,000  and $36,000 during the first year the truck is in service.

By 2030, the combination of both phases of standards will cut fuel use by 1.4 million barrels per day and reduce carbon pollution by 270 million metric tons, compared to the fuel use and emissions that would occur without fuel efficiency improvements.

Companies stand to save nearly $8 billion dollars in 2030 too, as the cost-per-mile to move freight will decrease by $0.07 a mile as a result of the second phase rules alone.

By 2040, these savings could grow to $25 billion annually, as the net effect of the second phase of the standard alone could be to reduce the per-mile cost of moving freight by 21 cents.

Our finding of significant financial benefits of strong fuel efficiency and GHG standards is consistent in magnitude with previous analysis. A recent report by the Consumer Federation of America looked at similar Phase 2 standards and found net savings of $250 to consumers, rising to $400 per household in 2035 as fuel prices and transportation services increase.

With such savings at hand, a natural question is why do we need new standards in the first place? We need new standards because well-designed federal standards foster the innovation necessary to bring more efficient and lower emitting trucks to market.

Strong standards break down barriers that keep technologies from moving from the test track to the assembly line.

Manufacturers need to be confident in market demand in order to develop and launch efficiency improvements. Strong standards give them the certainty they need.

Fleets are often weary of investing in advanced technologies; as such capital investments could put them at a disadvantage if fuel prices drop suddenly, like they did in 2008. For-hire trucking fleets also directly pass on a large percentage of their fuel bill through fuel surcharges to their customers, thus distorting the economic incentive to invest in efficiency.

Manufacturers and fleets can benefit significantly from strong standards. As the EDF analysis demonstrates, manufacturers will have a market for more valuable equipment; while fleets will achieve significant overall savings.

In fact, this is just the type of impact we are seeing from the first phase of heavy trucks standards, which went into effect at the start of this year. Fleets and Manufacturers are praising the rule and new, cost-effect offerings have come onto the market.

Moving forward on strong heavy-truck efficiency and emissions standards is a step that our country needs to take.

A First Look at the Clean Power Plan: Protecting Public Health and Cutting Carbon Pollution

Source: Flickr/ Rupert Ganzer

Source: Flickr/Rupert Ganzer

Earlier this week, our nation took a ground-breaking step by proposing to finally establish carbon pollution limits on existing power plants — the single largest source of climate-destabilizing pollution in the U.S. and one of the largest in the world.

We have national limits on the other air pollutants emitted by these plants, including mercury and arsenic and smog-forming pollutants — and we urgently need to secure strong limits on carbon pollution.

Here’s a first look at the proposed Clean Power Plan and its “building blocks” — the opportunity for state leadership, the profound public health benefits for our communities and families, and the good news about cost savings for customers.

The Proposed Pollution Reductions

The Clean Power Plan would reduce carbon pollution from existing fossil fuel-fired power plants by approximately 30 percent by 2030, and could curb emissions by as much as 27 percent by 2020.

EPA looked at the existing power plants in each state, and evaluated four time-tested, cost-effective emission reduction pathways:

  1. The potential to improve power plant efficiency
  2. The potential to rely more on lower-emitting power plants such as combined cycle natural gas and less on higher-emitting power plants
  3. The potential to deploy zero emitting generation resources like wind and solar
  4. The potential to capture end-use energy efficiency opportunities.

EPA then added up these four “building blocks” to calculate the reduction that a State could achieve on average in its overall emission rate over 2020-2029 (the “interim” target), and what rate could be achieved in 2030:

State Flexibility & Innovation

Under the Clean Power Plan, states will control their own future.

States have the flexibility to deploy the emission reduction policies and pathways that make the most sense for them, maximizing cost-effectiveness and co-benefits for their citizens, so long as they achieved the required emission reductions.

Some states might choose to build their compliance plans around existing Renewable Energy Standards and energy efficiency programs. Others might choose to put in place an emission reduction trading program between power plants. Still others might choose to collaborate with other states to submit joint plans and capture the cost-effective emission reduction opportunities available across state boundaries.

Public Health Benefits

The public health benefits of the Clean Power Plan are extensive and will help ensure healthier and longer for our loved ones who suffer from heart and lung ailments, and for our children.

EPA’s analysis shows that the reductions in carbon pollution and the associated reductions in sulfur dioxide, oxides of nitrogen, and particulate matter that will happen as a result will generate health benefits of $55 to $93 billion per year in 2030.

The pollutants that contribute to the soot and smog that make people sick will be reduced by more than 25 percent in 2030 — avoiding 2,700 to 6,600 premature deaths and 140,000 to 150,000 asthma attacks per year.

From the soot and smog reductions alone — ignoring the important reductions in carbon pollution achieved — Americans will see 7 dollars in health benefits for every dollar invested through the Clean Power Plan.

Cleaner power will ensure healthier and longer lives for millions of Americans.

Electricity Rates & Reliability

EPA’s analysis also shows that there will be sufficient power generation capacity across the United States under this framework to meet demand.

The flexibility provided to States will allow them to design plans to secure reductions in carbon pollution without any risk to power reliability.  As has been true for the past 40 years, we will reduce air pollution and maintain reliable power.

Because the Clean Power Plan will spur investments in demand-side energy efficiency, in 2030 electricity bills are expected to be 8 percent lower than they would have been without the plan.

Under the Clean Power Plan we will have cleaner, safer power, lower electricity bills, cleaner air, and healthier lives.

Cleaner power for a stronger America.

Power plant rule a tipping point for clean energy economy

By Cheryl Roberto, Associate Vice President, Clean Energy Program

For those of us (and all of you) who’ve been urging the government to implement meaningful climate policy, the release yesterday of a plan to cut carbon emissions from power plants has been a long time coming. But it finally came.

The U.S. Environmental Protection Agency’s proposed carbon pollution rule for existing fossil-fueled power plants – also known as the Clean Power Plan – are a huge win for our climate.

We also think it could go down in history as the tipping point in our nation’s transition to a clean energy economy. Here’s why:

Old, dirty power plants will be retired

The nation’s fleet of coal-fired power plants is the single largest source of carbon pollution in the U.S. and one of the largest in the world. Placing carbon regulations on this source of electricity for the first time in history will transform our energy system.

Utilities have acknowledged that it doesn’t make economic sense to pour money into retrofitting and retaining older, less-reliable coal-fired power plants when they need to focus investments on newer and more reliable plants.

This means that many of the most highly-polluting coal-fired power plants that provide electricity to our homes and businesses today will be retired. It presents a unique opportunity for clean energy solutions to fill the gap in generating capacity.

It may be one of the largest market opportunities in history to drive…clean energy on a national level.

Increasing our use of homegrown, renewable power sources and investing in proven tools such as energy efficiency, smart grids and demand response (which compensates electricity customers for conserving energy) will help fill this gap while reducing our reliance on fossil fuels that pollute the environment and contribute to climate change.

States will lead the way

EPA’s approach provides clear guidance for what limits and metrics must be met, but leaves states the flexibility to design solutions to meet those requirements as they see fit. This will encourage all states (even those which do not embrace the climate challenge) to look at clean energy technology as an attractive option when they seek to comply with the law.

Federal limits on carbon pollution from existing power plants are exactly the clarity states need to lead us to clean, reliable and affordable energy for all Americans – now and in the future.

Entrepreneurs, investors ready to jump in

What’s more, the new EPA plan – once it’s final – will give entrepreneurs, corporations and venture capitalists the market signal they need to go full steam ahead with low-carbon innovations. It may be one of the largest market opportunities in history to drive the development and implementation of clean energy on a national level.

At Environmental Defense Fund, we’re right in the middle of many of these promising solutions, working with state legislators and regulators to clear outdated rules that mire us in the past and discourages innovators.

Paving the way for a cleaner, healthier future

We’re working with financial institutions to develop new funding opportunities for clean energy investments that will help raise the estimated $10.5 trillion needed over the next two decades to transition our world to a clean energy economy.

We’re working with energy research pioneer Pecan Street Inc.in Austin, TX to test customer energy management solutions such as rooftop solar, home energy storage, learning thermostats and time-of-use energy pricing (which incentivizes people to use electricity during periods of low, or “off-peak” energy demand).

And we’re pushing to make energy efficiency a cornerstone of America’s energy policy.

It may not be as sexy as fuel cells and solar panels, butbuilding a more efficient energy system — from power plants to transmission lines to homes and buildings — is the most affordable and cleanest path forward.

The United States is expected to spend about $2 trillion over the next two decades to replace our outdated electric infrastructure. These new regulations are a step in the right direction toward ensuring that these investments are spent on our future and not entrenching us in our past.

EPA’s proposed rule means good jobs, economic development and a healthier planet.

And as a pioneer at the forefront of this movement, EDF is determined to make sure we stay on track.

Study: Climate change may push hurricanes farther north, south

A satellite image of Irene, a Category 1 hurricane, as it made landfall in North Carolina in August of 2011. Source: NASA/NOAA GOES project

The hurricane season of 2014 just kicked off, and with two devastating storms wreaking havoc along the northeastern United States coast over the last few years, it’s no wonder everyone’s on edge.

We’re concerned about hurricanes becoming more frequent and intense, and about the worsening storm surge caused by a rise in sea levels. But flying under the radar is a fourth link between hurricanes and climate change: how climate change affects the location of hurricanes.

new study led by researchers at the National Oceanic and Atmospheric Administration, the Massachusetts Institute of Technology and Princeton University found that hurricanes have been shifting pole-ward at a rate of 30 to 40 miles per decade over the last 30 years.

It means they are moving closer to major population centers such as Washington, New York and Boston.

The likely cause? Human-caused climate change.

The migration of hurricanes has “potentially profound consequences for life and property,” the authors of the study warn in an article published recently in the journal Nature.

Increasing hazard exposure and mortality risk from tropical cyclones may be compounded in coastal cities outside the tropics, while being offset at lower latitudes.”  

Linking climate change to hurricane location

This finding is an important advancement in scientists’ understanding of how climate change has already contributed to extreme weather events. Research shows that the rise in global temperatures already causes more warm days, heat waves, and heavy rainfall.

Detecting trends in hurricane activity has been difficult, however, due to inconsistent and often unreliable historical data.

To get around this data challenge, the scientists at NOAA, MIT and Princeton developed a new technique that relies on a dependable subset of the data, and which teases out natural events such as El Niño to detect a distinct relationship between hurricane activity and climate change.

Their conclusion: Hurricanes are drifting toward the poles most likely due to an expansion of the Hadley Cell, a permanent atmospheric circulation feature that carries heat from the tropics to the Earth’s temperate zones.

Scientific understanding is that the Hadley Cell expansion is a result of the increase in heat-trapping gases in the atmosphere from human activities. So as we continue to drive cars, generate electricity at fossil-fueled power plants, cut down trees, and farm – we are indirectly pushing hurricanes farther north and south.

The new study is groundbreaking not only because it uses a novel technique, but also because it links a hurricane trend to climate change.

What we know so far

So where are we today with hurricanes and climate change?

Scientists studying hurricanes:

  • Have found no observed trend in frequency
  • Have not been able to detect trends in intensity  and duration
  • Are confident that human-caused sea level rise is contributing to storm surge
  • Expect the frequency of intense storms to increase in the future
  • Have now detected a robust trend in location shifts that is likely due to human activity

This new research presented in Nature suggests that hurricanes are migrating toward the poles and may devastate densely populated coastal regions that had previously, for the most part, been spared such storms.

It’s yet another reason why we must act now to curb carbon pollution and limit climate change.
