Years of research about the people who work in the federal government finds that most of them are devoted civil servants who are committed to civic duty without regard to partisan politics.
Reducing particle pollution can save thousands of lives, but states need more data to inform better controls. An atmospheric scientist explains what data and actions are needed.
On Feb. 7, 2024, the EPA strengthened the federal limit for annual levels of fine particulate air pollution, or PM2.5. Many serious health effects have been linked to PM2.5 exposure.
In Sackett v. EPA, a suit filed by two homeowners who filled in wetlands on their property, the Supreme Court has drastically narrowed the definition of which wetlands qualify for federal protection.
Fossil fuel power plants can avoid most emissions by capturing carbon dioxide and pumping it underground. But to be a climate solution, that carbon has to stay stored for thousands of years.
After the Supreme Court overturned the Obama administration’s strategy for reducing power plant carbon emissions in 2022, the Biden administration is taking a narrower but still ambitious approach.
A new study reveals wide disparities among state-issued Clean Water Act fines, and even among federal fines from regions to region. A law professor explains why it may be illegal.
