California Restricts Pollutants from Cow Flatulence to Diesel Emissions

California on Monday moved to restrict air pollutants from sources as diverse as diesel trucks and cow flatulence, the latest of several efforts in the most populous U.S. state to reduce emissions leading to climate change.

Under a bill signed Monday by Democratic Governor Jerry Brown, the state will cut emissions of methane from dairy cows and other animals by 40 percent and black carbon from diesel trucks and other sources by 50 percent.  The bill also mandates the state to reduce emissions of fluorinated gases, or hydrofluorocarbons used in refrigeration.

The measure comes on the heels of several climate-change bills signed in recent weeks by Brown, including one that by 2030 will mandate an overall reduction of greenhouse gas emissions to 40 percent below the level released in 1990.
