Climate Change and Human Health – The Win-Win of Tackling Air Pollution

, senior climate scientist

The World Health Organization estimates that an alarming 7 million people die prematurely each year as a result of air pollution. To help tackle this issue, this year’s World Environment Day (June 5) is shining a spotlight on this environmental threat and the multiple benefits derived from tackling it. To learn more, I spoke with Sandra Cavalieri, the Coordinator of the Health Initiative of the Climate and Clean Air Coalition’s Secretariat who is contributing to World Environment Day.

Air Pollution Should be Monitored Using the Best Available Science: Meh, Says the EPA

, Research Analyst

Air pollution causes serious harm to our society – from coughing, to smog in the air, to a visit to the emergency room. And the only way to mitigate the threat of air pollution is to use the best available science and technology to measure it accurately. The Environmental Protection Agency (EPA) appears to disagree. The agency has quietly finalized a rule that ignores its mission to protect human health and the environment by instead focusing on saving industry money.

Illinois’ Energy Future: Less Coal, More Renewables

, lead Midwest energy analyst

Yesterday the Illinois Environmental Protection Agency submitted a proposal to set stricter air pollution limits in the ongoing state rulemaking over Dynegy-Vistra’s fleet of coal-fired power plants in Illinois.

The proposal is a good thing for lowering harmful air pollution. Dynegy-Vistra has also discussed the possibility of retiring some of its remaining coal-fired units in the near future.

¿Quién respira el aire más contaminado por emisiones de vehículos en California?

, Senior vehicles engineer

Existe una gran disparidad en la exposición a la contaminación entre los grupos raciales y étnicos de muchos lugares de EE.UU. Vivimos en una sociedad desigual donde la contaminación del aire es una de las desigualdades menos visibles, pero que impacta tremendamente  la salud humana. Cuantificamos la exposición a la contaminación vehicular en California por grupo demográfico y encontramos que afroamericanos, latinos y asiáticos, así como las personas de bajos ingresos están mucho más expuestos que las comunidades blancas y afluentes.

Air Pollution from Vehicles in California: People of Color Bear the Biggest Burden

, Senior vehicles engineer

Cars, trucks, and buses are a significant source of air pollution in California. But how much pollution is attributable to these vehicles and who is exposed to this pollution? To help answer these questions, I’ve used a computer model to estimate the amount of fine particulate matter air pollution (known as PM2.5) created by using on-road vehicles (cars, trucks, and buses). The findings are troubling, both because they show that people of color are exposed to higher levels of harmful air pollution and because this result is likely not to be a surprise to many Californians (full report available in English and Spanish). The study supports the claims many have been making for decades – that on average, African American, Latino, and Asian Californians are exposed to more PM2.5 pollution from cars, trucks, and buses than white Californians. In fact, these groups are exposed to PM2.5 pollution 43, 39, and 21 percent higher, respectively, than white Californians.
