Air pollution and health

Air pollution particles from coal-fired power plants are more harmful to human health than many experts realized, and it’s more than twice as likely to contribute to premature deaths as air pollution particles from other sources, new research demonstrates. In the study, published in the journal Science, colleagues and I mapped how U.S. coal power plant emissions traveled through the atmosphere, then linked each power plant’s emissions with death records of Americans over 65 years old on Medicare. Our results suggest that air pollutants released from coal power plants were associated with nearly half a million premature deaths of elderly Americans from 1999 to 2020. It’s a staggering number, but the study also has good news: Annual deaths associated with U.S. coal power plants have fallen sharply since the mid-2000s as federal regulations compelled operators to install emissions scrubbers and many utilities shut down coal plants entirely. In 1999, 55,000 death...

A nationally representative survey of 8,027 Americans shows that across all racial demographics, overall interest in purchasing electric vehicles is high. Among those surveyed, 33% of white respondents, 38% of Black respondents, 43% of Latinos and 52% of Asian Americans say they would “definitely” or “seriously consider” purchasing or leasing an EV as their next vehicle. The survey was conducted by Consumer Reports, with input from the nonprofit advocacy groups GreenLatinos, the Union of Concerned Scientists and EVNoire and administered between Jan. 27 and Feb. 18, 2022, by NORC at the University of Chicago, an objective, nonpartisan research organization. Electric vehicles are critical for reducing transportation emissions, but communities of color currently adopt this key technology at lower rates than white drivers. This survey, for which I was an adviser, helps to shed light on some of the reasons for this disparity. Cleaner air for all Air pollut...

Cooks love their gadgets, from countertop slow cookers to instant-read thermometers. Now, there’s increasing interest in magnetic induction cooktops – surfaces that cook much faster than conventional stoves, without igniting a flame or heating an electric coil. Some of this attention is overdue: Induction has long been popular in Europe and Asia, and it is more energy-efficient than standard stoves. But recent studies have also raised concerns about indoor air emissions from gas stoves. Academic researchers and agencies such as the California Air Resources Board have reported that gas stoves can release hazardous air pollutants while they’re operating, and even when they’re turned off. A 2022 study by U.S. and Australian researchers estimates that nearly 13% of current childhood asthma cases in the U.S. are attributable to gas stove use. Dozens of U.S. cities have adopted or are considering regulations that bar natural gas hookups in new-construction h...
