Air toxic emissions from on-road mobile sources are significant contributors to the degradation of air quality in urban and dense population centers. Research led by the United States Environmental Protection Agency (EPA) identified more than 1162 hazardous air pollutants (HAPs) in the exhaust and evaporative emissions from on-road mobile sources.

A new study shows what it will take for the plastics industry to become completely sustainable: lots of recycling combined with the use of CO2 from the air and biomass. 

Carbon dioxide emissions from wildfires, which have been gradually increasing since 2000, spiked drastically to a record high in 2021, according to an international team of researchers led by Earth system scientists at the University of California, Irvine.

North Carolina State University researchers used satellite imagery and field sensors to estimate worldwide changes in plant leaf growth due to global warming.

Air pollution is an existential threat to millions of Americans with asthma and other health issues. 

Using commercial, high-resolution satellite images and artificial intelligence, an international team including NASA scientists mapped almost 10 billion individual trees in Africa’s drylands in order to assess the amount of carbon stored outside of the continent’s dense tropical forests. 

Two banned insecticides known to linger in the atmosphere have been all but eliminated from North America’s Great Lakes region, a study finds.

A new study from Tulane University which compared popular diets on both nutritional quality and environmental impact found that the keto and paleo diets, as eaten by American adults, scored among the lowest on overall nutrition quality and were among the highest on carbon emissions.

New research led by Scripps Institution of Oceanography at UC San Diego has confirmed that coastal water pollution transfers to the atmosphere in sea spray aerosol, which can reach people beyond just beachgoers, surfers, and swimmers.

Municipal wastewater treatment plants emit nearly double the amount of methane into the atmosphere than scientists previously believed, according to new research from Princeton University.
