|States adopting the California regulations.|
San Jose Mercury News. California Deputy Attorney General Mark Melnick defended California’s regulations establishing limits on carbon-dioxide emissions from new light-duty vehicles (LDV) starting in 2009 in US District Court on Friday.
A coalition of automakers filed suit against the regulations, approved in 2004, that would cut CO2 emissions from new vehicles by up to 30% by 2016. (Earlier post.) Automakers are challenging the rules as a de-facto mandate on fuel-economy standards, which only the federal government can set.
The state attorney general’s office has urged U.S. District Court Judge Anthony Ishii to rule immediately, while automakers want to proceed to a trial that is scheduled to start Jan. 30. Ishii took more than two hours of arguments Friday and said he would take the state’s motion under submission.
The limits on tailpipe greenhouse gas emissions is an important component of the larger state effort to reduce greenhouse gas emissions. California is the 12th largest emitter of greenhouse gases in the world.
The state Assembly recently passed, and Governor Schwarzenegger is expected to sign, AB 32, the California Global Warming Solutions Act of 2006, which is intended to bring statewide emissions of greenhouse gases from stationary (i.e., industrial and power-generating) sources back down to 1990 levels by 2020—an estimated cut of 25%.
