Automaker Rankings Revisited—Does Volkswagen Now Have the “Dirtiest Tailpipe”?

, vehicles analyst

Last year, we released our semi-regular report card on the auto industry, the Automaker Rankings, where Volkswagen tied for 3rd place behind Hyundai-Kia and Honda.

I’ve talked here, here, and here about the EPA National Ambient Air Quality Standards (NAAQS) update to the ozone standard.  Today is the last day of the EPA’s public comment period (to which I have submitted a comment). So I thought it would be a good time to do a quick review of the top five reasons the ozone standard should be strengthened in order to provide an adequate margin of safety for the most vulnerable populations—including the elderly, children, and those with lung diseases.

EPA’s Clean Air Scientific Advisory Committee Comes to Agreement on Ozone Standard Recommendation

, lead analyst, Center for Science and Democracy

Today the EPA’s chartered Clean Air Scientific Advisory Committee (CASAC) agreed on a recommendation to Administrator McCarthy regarding an update to the ambient air pollution standard for ozone (To get up to speed on the ozone standard update process, see my previous post on the topic).
