Memorandum 25 March 2025 Page 7 • The Advanced Clean Trucks regulation requires between 40 and 75 percent of new medium- and heavy-duty vehicles sold in California to be ZEVs or near-zero-emissions vehicles by 2035. • The Low-Carbon Fuel Standard (Executive Order S-1-07), as amended in 2019, requires a 20 percent reduction in the carbon intensity of California's transportation fuels by 2030. • SB 375 establishes regional GHG emissions reduction targets from passenger vehicles for 2020 and 2035 by requiring metropolitan planning organizations to develop and implement Sustainable Communities Strategies that align regional transportation planning efforts with regional housing allocation needs. • The Truck and Bus Regulation, as amended in 2014, requires heavy-duty diesel vehicles that operate in California to reduce TAC emissions from their exhaust. As of January 1, 2023, nearly all trucks and buses are required to have 2010 or newer model year engines, to reduce particulate matter and oxides of nitrogen emissions. • The Tractor-Trailer GHG Regulation (13 CCR 1956), adopted by CARB in 2008, requires tractors and trailers to use aerodynamic technologies and low rolling resistance tires, to reduce fuel use and emissions. California’s Climate Change Scoping Plan In December 2008, CARB adopted the Climate Change Scoping Plan to identify how the state can achieve its 2020 climate action goal under AB 32. In 2017, CARB updated the Scoping Plan to identify how the state can achieve its 2030 climate action goal under SB 32 and substantially advance toward its 2050 climate action goal under Executive Order S-3-05. The 2017 Scoping Plan includes the regulatory programs identified above, such as the Advanced Clean Cars Program, Low-Carbon Fuel Standard, Renewable Portfolio Standard Program, energy efficiency standards, SLCP Reduction Strategy, and Cap-and-Trade Program (CARB, 2017b). In December 2022, CARB adopted the 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan), which outlines a roadmap to achieve targets for carbon neutrality and reduce anthropogenic GHG emissions by 85 percent below 1990 levels no later than 2045 (CARB, 2022). Building on the 2017 Scoping Plan, the 2022 Scoping Plan evaluates the progress made toward meeting the 2030 GHG emissions reduction target that was established in SB 32 and identifies a technologically feasible, cost-effective, and equity-focused path to achieve carbon neutrality by 2045 or earlier. In December 2022, CARB adopted the 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan), which outlines a roadmap to achieve targets for carbon neutrality and reduce
