SB 1383: Reducing Climate Pollutants from Waste

Senate Bill 1383 and the County Ordinance 

In September 2016, the State set methane emission reduction targets for California in Senate Bill 1383, intended as a statewide effort to reduce emissions of short-lived climate pollutants (like organic waste) in various sectors of California’s economy. Implementing the statewide plan under SB 1383 will reduce short-lived, harmful, super pollutants with significant warming impacts, and is essential to achieving California’s climate goals.

SB 1383 establishes statewide targets to reduce the amount of organic waste disposed of in landfills (50% reduction by 2020 and 75% by 2025). It also sets a goal to rescue at least 20% of currently disposed of edible food by 2025 and redirect that food to people in need. The California Department of Resources, Recycling, and Recovery (CalRecycle) worked to develop regulations to achieve the goals of SB 1383. These new regulations were finalized by CalRecycle on November 4, 2020, and take effect in January 2022. In October 2021, the County passed an ordinance for areas located within Unincorporated San Mateo County in accordance with SB 1383.

Types of Organic Waste 

The State defines “Organic waste” as food, landscape, and pruning trimmings, lumber, wood, manure, cardboard, paper products, printing and writing paper, and other plant and animal-based products. Organic waste in landfills produce 20% of the state’s methane, a climate super pollutant 84 times more potent than carbon dioxide. Organic waste, such as food scraps, yard trimmings, paper, and cardboard, make up half of what Californians send to landfills.

Compliance with SB 1383

For Residents:

  • Residents are required to participate in their jurisdiction’s organics curbside collection service.

Please refer to the Dense vs Low Populated Areas Map. All unincorporated county areas shown in green on the map above are considered Densely-Populated Areas and will need to comply with the requirements of SB 1383. Residential customers in these areas are required to have curbside cart collection services of organics.  Commercial customers can self-haul or subscribe to curbside services. The areas shown in yellow on the map above are considered Low-Populated Areas which are exempt from the SB 1383 mandatory residential curbside services and are  not subject to the same regulations due to its low population density (less than 75 people per square mile).
