Scientists to EPA: Stop Sidelining Science in the Air Pollution Standard Update for Particulate Matter

, Research Director, Center for Science and Democracy

More than 200 air quality and public health experts have penned a letter expressing concern about the limited scientific input into an air pollutant standard update. The 206 scientists are deeply troubled by recent actions of the EPA on its update to the health-based standard for particulate matter, a pollutant comprised of tiny solid particles that has been linked to respiratory and cardiovascular effects and early death.

Scientists Cut Out of EPA’s Particulate Pollution Standard Setting

, Research Director, Center for Science and Democracy

In the latest of several moves targeting EPA air pollution protections, the Trump administration appears to have cut scientists out of a process for reviewing particulate pollution standards.  The move breaks with a longstanding process for how the agency gets independent scientific review into its decisionmaking on air pollution protections. Without such expertise involved, EPA won’t have the best available scientific input to keep people safe from air pollution, as the law requires.

Back to Bad Air: The Trump EPA’s Attack on Science and Our Health

, Research Director, Center for Science and Democracy

When he was first appointed, EPA Administrator Scott Pruitt vowed to bring the agency “back to basics” by focusing on clean air and water. One could be forgiven for assuming this meant he intended to preserve and strengthen America’s air pollution protections. That’s why it’s so jarring to see how severely his actions have undermined them. Read more >

The Wall Street Journal Gets it Wrong on EPA Scientific Integrity…Again

, science and policy analyst, Center for Science and Democracy

The Wall Street Journal ran an opinion piece yesterday titled “A Step Toward Scientific Integrity at the EPA” written by long-time critic of the EPA and purveyor of anti-science nonsense, Steven Milloy. His piece commends Administrator Pruitt on his recent dismissals of EPA advisory committee members, and questions the independence of advisory committees, like the EPA’s Science Advisory Board (SAB) and Clean Air Scientific Advisory Committee (CASAC), claiming that they contain biased government grantees and have made recommendations on ozone and particulate matter that aren’t supported by science. His arguments are twisted and unfounded, but are not surprising based upon his history working for industry front groups that attempt to spread disinformation to promote a science agenda benefitting powerful interests.

On Cars, Trucks, and Beauty in the Backcountry: 4 Lessons from a Summer Roadtrip

, , senior vehicles analyst

For my big summer vacation this year, I spent over a week traveling the mountain west, crossing four states (South Dakota, Wyoming, Montana, Idaho), traversing eight national monuments and parks, and racking up over 2300 miles. Because even when I’m on vacation I can’t stop thinking about transportation, I thought I’d share a few observations from the trip: Read more >
