Trump EPA Doing Something to Actually REDUCE Pollution from Trucks

, senior vehicles analyst

Today, EPA Administrator Andrew Wheeler announced an advanced notice of proposed rulemaking (ANPRM) to set more stringent pollution standards on heavy-duty trucks. This follows up on the 2018 announcement of the administration’s “Cleaner Trucks Initiative” and represents the only step thus far the administration has made to actually, you know, do its job and reduce pollution.

Air Pollution from Cars, Trucks, and Buses in the US: Everyone is Exposed, But the Burdens are not Equally Shared

, Senior vehicles engineer

 Air pollution has significant impacts to public health and the cars, trucks, and buses on America’s roads contribute to this problem. While we are all exposed to this pollution, there are significant differences in the average exposure to this air pollution by different racial groups in the U.S. and exposure also varies greatly depending on where in the U.S. you live.

¿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.

New Study Shows Electric Vehicles Can Have Significant Climate and Air Quality Benefits Compared to Gasoline Cars

, Senior vehicles engineer

A new study from the University of Minnesota shows that plug-in electric vehicles have both an air quality and global warming emissions benefit when they are charged using electricity generated from natural gas or renewable sources. However, the research finds that using electricity from coal-fired power plants in an EV is likely to have worse emissions than an average gasoline vehicle. This result isn’t surprising, but it’s also important to put in context. Many regions in the US use very little coal to generate electricity and the fraction of electricity in the US produced from coal has been dropping – meaning many EVs are delivering emissions benefits today and have the potential to deliver even more in the future.
