California aims to slash emissions of methane, hy-drofluorocarbons and black carbon 40 percent to 50 percent by 2030, under a draft plan state air quality regulators released April 11. 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 waste in landfills; reduce fugitive methane emission from oil and gas systems; and accelerate the use of refrigerants with low-global warming and the adoption of more efficient refrigeration systems.
