Recentky I came out of Safeway and walked into a cloud of exhaust fumes coming from a parked car. Now the hot weather is coming, out of the woodwork come the drivers who keep their cars idling just for the AC. Please turn off your engines! Roll down the windows or do your waiting inside one of the air conditioned stores. According to an EDF study: “every 10 minutes your engine is off, you'll prevent one pound of carbon dioxide from being released.”

Here is more info on idling cars and smog:

I'm especially concerned by unhealthy pollution and smog arising from micro-particulates and complex hydrocarbons in diesel engine exhaust, particularly trucks, construction equipment, and public transport like diesel buses and locomotives.

I would urge the Bay Area Air Quality Management District (BAAQMD) to take aggressive regulatory action to reduce and then eliminate oil-fueled diesel engine use in the Bay Area --- through strict standards backed by annual user-paid exhaust testing, along with an aggressive and realistic(!!!) plan to eliminate oil-fueled diesel engines with practical and economically viable alternatives, particularly compressed natural gas (CNG), which presently is being used in newer VTA hybrid buses. Gasoline-powered hybrid tech also could be a fallback option. Pure EV power only makes practical sense in very limited numbers of heavy vehicle applications.
