The power sector is the biggest source of emissions globally, but the rapid growth of wind, solar, and nuclear generation are at last pushing power sector emissions into decline, analysts say.

The fastest growing type of offset on the global carbon market subsidizes the distribution of efficient cookstoves in developing countries to reduce greenhouse gas emissions, but a new study finds that the stoves’ carbon saving credits are vastly overestimated, by a factor of 10.

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere.

Air conditioning doesn't just cool the air – it can also reduce the risk of harm from bushfire smoke, new research suggests.

Exposure to air pollutants, even at very low concentrations, was associated with adverse changes in cardiometabolic risk factors in a recent Finnish study.

Air pollution is the main environmental cause of early death, and new research from experts in Canada and the United States finds that, in about 75 years, climate change will see the number of air quality alerts in the U.S. to quadruple.

A Rutgers Health researcher collaborates to develop a microscopic technique that zeroes in on the poorly explored world of nanoplastics, which can pass into one’s blood, cells and brain.

Many electric vehicles are powered by batteries that contain cobalt — a metal that carries high financial, environmental, and social costs.

An international team of scientists led by DRI found evidence of Southern Hemisphere heavy metal pollution preserved in Antarctic ice cores from early Andean cultures and Spanish Colonial mining that predates the Industrial Revolution by centuries.

Environmental epidemiologists at Columbia University Mailman School of Public Health, in collaboration with an interdisciplinary team of researchers at Oregon State University, Pacific Northwest National Labs, and Mt. Sinai School of Medicine, report on the findings of a new study of air pollution exposures collected using personal wristband monitors worn by pregnant individuals in New York City matched with data from a questionnaire.
