California Aims to Slash Potent GHGs by 2030

The proposal is the latest iteration of the California Air Resources Board’s strategy to target short-lived climate pollutants, greenhouse gases with far more heat-trapping potential than carbon dioxide.

Building on the state’s existing climate and air pollution programs, the plan proposed new measures to reduce emissions of black carbon, or soot, from off-road and non-mobile sources, including forests; cut methane emissions from dairy operations in half; eliminate the disposal of organic ...
