Memorandum <br />25 March 2025 <br />Page 6 <br />The Short-Lived Climate Pollutant (SLCP) Reduction Strategy and SB 1383 <br />Promulgated in 2016, California Senate Bill (SB) 1383 set a statewide target to reduce organic <br />waste disposed of in landfills of 50 percent by 2020 and 75 percent by 2025. In addition, SB <br />1383 requires recovering at least 20 percent of disposed edible food for human consumption by <br />2025. As organic waste is a primary substance that generates LFG, diverting organic waste from <br />landfills can reduce LFG emissions. <br />The Short-Lived Climate Pollutant (SLCP) Reduction Strategy, adopted by CARB in 2017, is <br />California’s plan for reducing emissions of high global-warming potential gases with short <br />atmospheric lifetimes. SLCPs include methane, hydrofluorocarbons, and anthropogenic black <br />carbon. In accordance with SB 1383, the SLCP Reduction Strategy has set the following targets <br />for statewide reductions in SLCP emissions: <br />• 40 percent below 2013 levels by 2030 for methane and hydrofluorocarbons; and <br />• 50 percent below 2013 levels by 2030 for anthropogenic black carbon. <br />The SLCP Reduction Strategy also provides specific direction for reductions from dairy and <br />livestock operations and from landfills by diverting organic materials. <br />California On-Road Vehicle Emission Regulations <br />The State of California has established statewide emission and fuel economy regulations for <br />vehicles that align with or supersede the national standards. The key state regulations related <br />to vehicles emissions are as follows: <br />• The Pavley Regulations (AB 1493), as amended in 2009, required a 30 percent reduction <br />in state GHG emissions from new passenger vehicles from 2009 through 2016. <br />• The Advanced Clean Cars Program extends the Pavley Regulations beyond 2016 and <br />established a technology mandate for zero-emission vehicles (ZEVs). <br />• The Advanced Clean Cars II Program requires all new passenger cars, trucks, and sport <br />utility vehicles sold in California to be ZEVs by 2035. <br />• Executive Order N-79-20 established a goal that 100 percent of in-state sales of new <br />passenger cars and light-duty trucks will be zero-emission by 2035, which is supported <br />by the Advanced Clean Cars II Regulations.
