The California Air Resources Board (ARB) has released , for public review, a concept paper to initiate discussion on the development of a Short-Lived Climate Pollutant Reduction Strategy. Short-lived climate pollutants (SLCPs) include methane, tropospheric ozone, black carbon, and fluorinated gases.

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. Carbon-reduction policies significantly improve air quality.
