California ARB releases concept paper for public review on reducing short-lived climate pollutants

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. They are powerful climate forcers that remain in the atmosphere for a much shorter period of time than carbon dioxide. Their global warming potential (GWP) can be tens to thousands of times greater than that of carbon dioxide.

Senate Bill 605 (Lara, Chapter 523, Statutes of 2014) requires ARB, in coordination with other state agencies and local air districts, to develop a SLCP Strategy by the end of 2015, to further reduce SLCP emissions in California.

The Concept Paper presents initial ideas that will be considered and evaluated in the coming months by ARB staff, in coordination with other agencies, as it develops a SLCP Strategy pursuant to SB 605.

The concepts included in this discussion draft do not represent commitments at this time, nor do they comprise an exhaustive list of elements or considerations that may be included in the Strategy or shape its development. The intent of the paper is to elicit new ideas and refine strategies to reduce emissions of SLCPs throughout the state.

The Concept Paper will be discussed at a 27 May public workshop. The comments received on the Concept Paper will inform the development of a draft Strategy that ARB expects to release for public comment later this summer. ARB welcomes broad participation among stakeholders, experts and interested parties throughout this process.
