Purpose of Dairy/Livestock Working Group

Short-lived climate pollutants (SLCPs) are powerful climate forcers that remain in the atmosphere for shorter periods of time than carbon dioxide but can be tens to thousands of times more potent. Senate Bill 605 (Lara, Chapter 523, Statutes of 2014) and 1383 (Lara, Chapter 395, Statutes of 2016) directed ARB and other agencies to develop and implement strategies to reduce the three main SLCPs: methane, black carbon, and hydrofluorocarbons. Senate Bill 1383 contains detailed requirements for the reduction of methane emissions from landfills and the dairy and livestock sector. To facilitate development of measures to reduce dairy and livestock emissions, SB 1383 requires ARB to work with a broad range of stakeholders to identify and address technical, market, regulatory, and other challenges and barriers to the development of dairy methane emissions reduction projects. In keeping with this requirement, ARB, the California Department of Food and Agriculture, the California Energy Commission, and the California Public Utilities Commission convened a Dairy and Livestock Working Group.
