Through the Bipartisan Infrastructure Law, school systems such as the Palmyra-Eagle district have used federal grants to buy a handful of buses fitted with such tech...

Groups concerned about air pollution and public health are asking the city councils of Long Beach and Los Angeles and their respective Harbor Commissions to pass major restrictions on air pollution from ships. The "Ports for People" ordinance would require agencies to take steps to reduce pollution from cargo ships by 50% from 2019 levels by 2030, and to achieve 100% zero-emission shipping at the ports by 2040.

In some cases, air-quality tests at some facilities found, “It was no better to be inside than to be outside,” according to a researcher.

Every year, wildfires across the western U.S. and Canada send plumes of smoke into the sky. When that smoke blows into southwestern Idaho’s Treasure Valley, it blankets Boise-area residents in dirty air.

Air pollution from wildfire smoke — a brew of pollutants, water vapor, and fine debris — is a growing public health problem.

Data collected from six facilities in 2021, including two in the Missoula area, showed that in some buildings indoor and outdoor air quality were almost identical on smoky days.
