EPA Head Lies about Fuel Economy Fines in Push for Weaker Car Standards

, senior vehicles analyst

In an interview with Bloomberg Media on February 4th, EPA Acting Administrator Andrew Wheeler stated that manufacturers have paid $77 million in fines for not complying “with the current Obama numbers,” going on to say that “it’s incorrect to say that the automobile manufacturer can comply with the Obama numbers. We want a more realistic number.”

In waging this war on “the Obama numbers”, Andrew Wheeler is waging a war on facts in order to increase pollution from passenger cars and trucks and force consumers to pay more at the pump, lining the pockets of the oil industry with whom he has met repeatedly in his short tenure at EPA.

¿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.
