New analysis: Americans across the country suffered from high ozone pollution levels of this summer

By Taylor Bacon / Published: October 20, 2021

In addition to checking the temperature and the chance of rain before leaving home, many people have been forced to add a new indicator to their daily weather check – air quality.

Ground-level ozone pollution – more commonly known as smog – reached dangerous levels across the U.S. this summer. EDF’s new analysis found that almost every state experienced unhealthy levels of it, with millions of Americans exposed to dangerous air pollution.

The current national standard for ground-level ozone pollution is 70 parts per billion. As you can see from the maps above, 45 states had at least one day between March and August with levels that exceeded that limit.

However, there is a substantial and growing body of scientific evidence that shows serious health effects from ground-level ozone exposure at levels below the current standard. When the data is expanded to consider ground-level ozone levels greater than 60 parts per billion, which would be a health-based standard more consistent with the scientific evidence, the picture of summer ozone levels is even more concerning – all but one state (Hawaii) had at least one day with levels that exceeded that amount.

Our analysis also found:

  • The Western U.S. experienced the worst ozone levels in the country this summer. California, Arizona and Colorado experienced the most high-ozone days between March and August.
  • 343 counties recorded at least one high-ozone day. San Bernardino, California recorded the most exceedances – 112 high-ozone days between March and August, including almost every day in July and August.
  • More than 31 million people live in the 24 counties that had more than 20 high-ozone days between March and August, including Denver County in Colorado, Maricopa County in Arizona, and Los Angeles County in California.
  • If you use the more health-protective standard of 60 parts per billion, a majority of days between March and April had unhealthy ozone levels across the Western U.S.
  • In Arizona, under the 60 parts per billion standard, 89% of days between March and August had unhealthy ozone levels somewhere in the state.

There were many wildfires this summer and wildfire smoke is one of the sources that can contribute to elevated levels of ozone pollution. EPA establishes standards based on health science alone, and the agency has long had policies in place that allow states to account for truly exceptional events. Our analysis includes all recorded high ozone readings and does not exclude any high ozone days

Where the U.S. stands going into COP26

By Danielle Arostegui / Published: October 12, 2021

After a year-long delay from the pandemic, COP26 — the next UN meeting aimed at accelerating global action on climate change — is right around the corner. As a newly rejoined Party to the Paris Agreement under the leadership of President Biden, the United States will be arriving under much different circumstances than the last COP. But will other countries see the U.S. participation and its new commitments as credible? Will the United States be positioned to push global ambition to the levels needed to beat the climate crisis? The answers to those critical questions depend on how much policy progress the U.S. can make at home.

In April, the United States renewed its commitment to meeting global climate targets, including through an ambitious new nationally determined contribution (NDC) that pledges to reduce U.S. emissions by 50-52% from 2005 levels by 2030. While highly ambitious, multiple analyses have demonstrated that this goal is also achievable, lending much-needed credibility to the U.S. pledge. Since then, the Biden administration has unveiled a series of actions intended to move the country towards achieving that goal.

Critically, one of the largest and most significant components of the president’s plan to tackle climate change is a piece of legislation that is currently in active stages of negotiation in Congress. Getting this bill and the included climate investments across the finish line will be crucial to meeting our climate goals. On top of that, the U.S. must also ratchet up regulatory climate action at the federal and state level to meet our 2030 pledge, as incentives and investments alone won’t be enough to slash emissions at the pace and scale needed.

So what has the U.S. accomplished since announcing its new NDC in April and what is still on the table? Here is where progress stands.

Beyond R&D: Climate innovation policy can help the U.S. meet the moment

By Natasha Vidangos / Published: September 27, 2021

Together with Third Way, EDF co-hosted a Climate Week 2021 event on how U.S. climate innovation policy can accelerate a cleaner, stronger and more equitable economy. Here are four big takeaways.

(Caption: Speakers included Mandela Barnes, Lieutenant Governor, Wisconsin; Chris Deschene, Board Member, National InterTribal Energy Council; Jason Walsh, Executive Director, BlueGreen Alliance; Jetta Wong, Senior Fellow, Information Technology and Innovation Foundation, and President, JLW Advising. The event was moderated by Natasha Vidangos, Senior Director, Climate Innovation and Technology at EDF, and Josh Freed, Senior Vice President, Climate and Energy Program at Third Way.)

Climate innovation is a powerful tool that can create high-quality jobs, improve the quality of life for all communities and catalyze the breakthroughs needed to reach net-zero emissions by no later than 2050. To take advantage of the full opportunity, however, we need strong policies and approaches now that can deliver on all of these challenges, as a recent Climate Week event hosted by Environmental Defense Fund and Third Way made clear.

Innovation in climate technologies includes many stages of development, from research and development through to demonstration and deployment. The U.S. is poised to make major investments in this area to combat climate change: President Biden has pledged to deliver the largest-ever federal investment in clean energy innovation, and the infrastructure and reconciliation packages currently under negotiation in Congress contain large amounts of funding, including specific investments in demonstration and deployment of key technologies. But these investments can feel abstract. What would a strong push for climate innovation mean for U.S. workers and communities, and how can we design these policies to deliver the maximum benefits for all?

Here are four major takeaways from the event, which brought together perspectives from government, labor and advocacy.

Four Reasons Petitions for Supreme Court Review of Climate Pollution Standards for Power Plants Should Fail

By Ashley Maiolatesi / Published: September 24, 2021

This coming Monday, the Supreme Court will consider hundreds of petitions for review, which ask the Court to take up cases for full consideration during its new term. Among the petitions for review are four from coal companies and states asking the Court to review the D.C. Circuit decision overturning the Trump administration’s rule weakening regulations of carbon pollution from power plants. For multiple reasons the four petitions lack merit.

The Clean Power Plan, adopted in 2015, established the first-ever national limits on climate pollution from existing power plants. In 2019, the Trump administration adopted regulations to repeal the Clean Power Plan and replace it with the “ACE” rule – which did virtually nothing to limit pollution.

This January the D.C. Circuit struck down this attempt, issuing a narrow opinion that explained how ACE misinterpreted specific language in section 111 of the Clean Air Act.

In the months since the D.C. Circuit’s decision, neither the Clean Power Plan nor the Trump administration’s weak replacement rule has been in effect, meaning that no power plants or operators have experienced harm under either rule. Additionally, EPA has been working from a clean slate on new safeguards that will reflect current information about our rapidly changing power sector. Despite this, and the fact that no one is subject to any compliance obligations under the Clean Power Plan or ACE, coal companies and 21 states are asking the Supreme Court to reverse the D.C. Circuit opinion and issue a statutory interpretation that limits EPA’s ability under the Clean Air Act to protect the public from climate pollution.

Effectively, they are asking the Court for an “advisory” opinion — a free-floating legal opinion untethered to any current dispute but intended to constrain future behavior. EDF is part of a coalition of environmental organizations that – along with almost two dozen states and cities, power companies and business associations – opposes this challenge.

Rather than take up this case in order to consider legal theories in the abstract, the appropriate course would be for the Court to allow EPA to complete its new rulemaking, which will be subject to judicial review once finalized. At that time, reviewing courts will be able to assess EPA’s actual application of its Clean Air Act authority in the context of real compliance obligations and a factual record that reflects current realities.

Here are four key reasons that the petitioners’ pleas for Supreme Court review should fail:

We need to go big to solve the climate crisis

The environmental integrity of emissions reductions depends on scale and systemic changes, not on sector of origin of the emissions

We urgently need to reduce greenhouse gas emissions far beyond current climate pledges, even if these were fully attained. But there’s a completely doable way to make major progress, near to hand.

Natural climate solutions can provide 20% of all the emissions reductions we need by 2050 to keep average global warming under 2 C. Stopping tropical deforestation, allowing tropical forests to regenerate and restoring degraded lands are the most important methods, particularly in the next decade. Letting countries or companies that exceed ambitious targets trade their surplus emissions reductions to those who fall short would permit much greater global emissions reductions than not trading. Countries could reach their targets more quickly, and trading would create more incentive to protect and restore land.

Some researchers and policy makers have held that nature-based solutions, such as stopping deforestation, are too risky. A forest you protect today could burn down tomorrow. But in fact, this problem exists with all emissions reductions, not only those based in terrestrial carbon. And nature-based solutions are worth considering as many of the highest quality and highest value emissions reductions that are feasible in the coming years.

A new article in Environmental Research Letters by scientists and economists from the Environmental Defense Fund and Princeton University shows that the best way to execute emissions reductions – whether they are from protecting forests or cutting down on fossil fuel –is to go big.
