A recent report by the state Air Resources Board showed that a Chevron refinery in Richmond fills the No. 1 spot for worst greenhouse gas emitters.
And the Chevron refinery in El Segundo has the No. 4 spot.
The BP refinery in Carson is No. 3
No. 6 is the Exxon refinery in Torrance.
But it seems that Chevron's emissions are getting the most attention. A group called Act for Climate Justice plans to protest in front of Chevron's San Ramon headquarters on Monday Dec. 7, coinciding with the first day of the international climate change negotiations in Copenhagen.
Despite producing millions of tons of emissions -- as any large petroleum refinery would do -- Chevron says it's also concerned with the environment and has been recognized for its efforts.
The whole global warming debate is an interesting international phenomenon that pits politician against activist, government against government, refinery against scientist, scientist against politician, and so on.
