EPA Administrator Wheeler Worsens Particulate Pollution Review Process

, Research Director, Center for Science and Democracy

In April, EPA Administrator Andrew Wheeler rejected the recommendations of his hand-picked science advisors on the particulate matter and ozone standard updates. Now, we again see him choose to meet a political deadline at the expense of a scientifically sound process. The bottom line is that Administrator Wheeler has made a small, inadequate, and unprecedented addition to what is still a very broken process of updating our National Ambient Air Quality Standard for particulate matter.

As Methane Levels in the Atmosphere Soar, Trump Administration Moves to Gut Regulations

UPDATE (August 29, 2019): Today the Environmental Protection Agency issued a new proposed rule that would loosen safeguards on methane, a powerful greenhouse gas. This proposal would allow increased methane emissions from oil and gas operations and weaken efforts to fight climate change. Rachel Cleetus, policy director for the Climate and Energy program at UCS, responds to this latest development.


 

Until recently, carbon dioxide has earned top billing among global warming gases. Emitted when fossil fuels burn, it remains the most prevalent heat-trapping emission driving climate change. Its concentration in the atmosphere has now reached levels unseen for three million years, helping to usher in an unprecedented decline in plant and animal species, according to a recent major United Nations report. Recent science is adding another gas to the marquee: methane. Just as we are learning how desperately we need to curb this gas, the Trump administration wants to kick the oil and gas industry’s methane standards to the curb.

Who Breathes the Dirtiest Air from Vehicles in the Northeast and Mid-Atlantic?

, Senior vehicles engineer

Most people know that cars, trucks, and buses  from our highways and city streets are a significant source of air pollution.  While pollution from transportation impacts all communities in the region to some degree, the people who face the greatest exposure to transportation pollution are those who live near highways, along major freight corridors, and in urban areas.

Climate Change and Human Health – The Win-Win of Tackling Air Pollution

, senior climate scientist

The World Health Organization estimates that an alarming 7 million people die prematurely each year as a result of air pollution. To help tackle this issue, this year’s World Environment Day (June 5) is shining a spotlight on this environmental threat and the multiple benefits derived from tackling it. To learn more, I spoke with Sandra Cavalieri, the Coordinator of the Health Initiative of the Climate and Clean Air Coalition’s Secretariat who is contributing to World Environment Day.

Air Pollution Should be Monitored Using the Best Available Science: Meh, Says the EPA

, Research Analyst

Air pollution causes serious harm to our society – from coughing, to smog in the air, to a visit to the emergency room. And the only way to mitigate the threat of air pollution is to use the best available science and technology to measure it accurately. The Environmental Protection Agency (EPA) appears to disagree. The agency has quietly finalized a rule that ignores its mission to protect human health and the environment by instead focusing on saving industry money.
