California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

California has already cut anthropogenic black carbon emissions by more than 90% since the 1960s, and existing measures are projected to cut mobile source emissions by 75% and total anthropogenic emissions by nearly 60% between 2000 and 2020.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
