A conservative science adviser to the T’s administration is casting doubt on longstanding research linking fossil fuel pollution to early deaths and health problems, worrying environmental experts.

At a meeting to review air pollution science compiled by staffers at the Environmental Protection Agency this week the advisory board chairman, Tony Cox – a consultant and statistician who has worked for the industry and criticized EPA standards – questioned whether soot from coal plants and cars can be directly blamed for asthma and cardiopulmonary problems.

Cox pushed staffers to specify what percentage of health problems are directly caused by the pollution or are just associated with it, a figure that the US government has not required in order to restrict pollutants that are known to harm people.

His comments appeared to confirm the fears of scientists who say the US government is now aiming to discredit research to bolster rollbacks of climate change and health regulations. The T’s administration is working to rescind rules for power plants, cars and oil and gas drillers.

“It’s really all a facade at this point,” said Christopher Frey, a scientist and professor at North Carolina State University who was chairman of the committee under the Obama administration from 2012 to 2015. “Almost everything that could have been changed to weaken the process has been changed, including how members have been appointed and the timeline.”

The EPA’s acting administrator, Andrew Wheeler, has appointed representatives from state-level agencies and industry to the science review committee, called the Clean Air Scientific Advisory Committee. EPA political leaders also disbanded two panels of experts on soot and smog.

EPA leaders have said the changes are meant to provide more balance in the advisory groups and to ensure regulations are not overly burdensome. The agency is also moving to restrict what kind of science it can consider in writing regulations for industry, excluding studies that cannot share the health information of participants or be reproduced.

The advisory committee was meeting as part of a regular review of the science behind clean air standards.

The process for updating air standards would normally take about three years, Frey said, but the EPA wants to shorten that to one year. Where there were 42 experts examining the science on air pollution and specifically on particulate pollution and smog, there are now seven, he noted.

A group of former members of the panel focused on soot wrote a 134-page letter to Cox this week documenting their many concerns that his committee does not have the expertise or time to adequately assess the science.

In these critical times …
… help us protect independent journalism at a time when factual, trustworthy reporting is under threat by making a year-end gift to support The Guardian. We’re asking our US readers to help us raise one million dollars by the new year so that we can report on the stories that matter in 2019. Small or big, every contribution you give will help us reach our goal.
The Guardian’s editorial independence means that we can pursue difficult investigations, challenging the powerful and holding them to account. No one edits our editor and no one steers our opinion.
In 2018, The Guardian broke the story of Cambridge Analytica’s Facebook data breach; we recorded the human fallout from family separations; we charted the rise of the far right, and documented the growing impact of gun violence on Americans’ lives. We reported daily on climate change as a matter of urgent priority. It was readers’ support that made this work possible.
As 2019 approaches, we would like to ask for your ongoing support. We believe that independent journalism has the power to drive change and build hope. And there are reasons for hope, from the inspiring wave of youth activism around gun violence to the wins of the #metoo movement; from a new dynamism countering the far-right to the most diverse (and yet still nowhere near diverse enough) Congress in American history that took shape after the recent midterms. People long to feel hopeful again, and rigorous journalism that is empirically sourced and emphatically delivered can be a powerful catalyst for change.
We’re in this together – with your support we can keep exposing the truth. We hope to pass our goal by early January 2019. We want to say a huge thank you to everyone who has supported The Guardian so far.
