As part of its groundbreaking plan to tackle air-polluting, climate-warming emissions, the California Air Resources Board has adopted six new rules for manufacturers, shippers, and truckers. Starting in 2010, vehicles that go in for a tune up or oil change will be required to fully inflate their tires; trucks and trailers must be fitted with fuel-saving devices; cargo ships will be disallowed from idling at ports; the chemical sulfur hexafluoride will be banned; and both the greenhouse gas perfluorocarbon and propellants in spray cans will be more strictly regulated. The board also adopted standards for using California’s forests to offset carbon. Hopefully there will be some forests left.
