SB 1383 Short-Lived Climate Pollutants

SB 1383, the Short-Lived Climate Pollutant Strategy, aims to divert 75% of organics in California from landfill and recover 20% of surplus edible food for human consumption by 2025. Regulations became effective on January 1, 2022.  The goal of SB 1383 is to reduce short-lived climate pollutant greenhouse gases (GHGs), like methane, which contribute to global climate change. SB 1383 specifically targets methane emitted from the waste sector, which is produced from the anaerobic decomposition of organic waste in landfills.

SB 1383 requires every Californian – residents, businesses, schools, apartments, government facilities and more – to ensure that organic waste is sorted correctly to prevent it from being landfilled. To learn more about how this regulation applies to different groups within Marin County, click the tiles below.  For a list of what waste goes where for your area, see our Who is My Hauler page.

Single-Family Residents

Residents of single-family homes, condos, and apartments with fewer than five units with landfill collection service must also subscribe to and utilize recycling and compost service. Please call your hauler to start service.

Multi-Family Residents

Your property manager or owner is required to subscribe to recycling and compost collection service. The recycling and compost containers must be as convenient to access as landfill containers and must be labelled with proper signage. If your property does not have compost service, please contact your property manager. Property Managers can learn more about their requirements in our SB 1383 At Work tab above.

Remember to STOP & SORT!

Please remember to “stop and sort” and pay close attention to the accepted and prohibited materials for each waste stream.

Property Managers and Owners

As a property manager or owner, you are required to establish and promote recycling and composting programs to comply with SB 1383 requirements. This includes the following:

Compost Service

State law mandates that multifamily buildings must provide compost service to all tenants. Contact your hauler to set up service.

This requires that building managers must:

  1. Subscribe to compost and recycle collection service.
  2. Place color-coded and labeled compost and recycle containers
  3. Ensure that materials are sorted into the proper bins.
  4. Periodically inspect bins and provide feedback to tenants, employees and contractors about incorrectly placed items.

Waste Sorting Education

  1. Educate employees, contractors, tenants, and subtenants about the law annually.
  2. Inform tenants no later than 14 days after move-in and at least 14 days prior to move-out about the rules.
  3. Post prominent signs on or near the collection containers. Visit our Posters and Labels page to download free posters for to your community.

Collection Container Convenience

Recycle and compost containers must be as convenient to access as landfill containers.

  1. Recycle, compost, and landfill containers must be in general vicinity of one another to make it easy for tenants to properly sort their waste.
  2. In common areas (besides restrooms), wherever there is a landfill receptacle, there must also be recycle and compost receptacles.


SB 1383 applies to all local education agencies including K-12 public and charter schools, school districts, and County offices of education.

California is home to more than 10,000 K-12 schools and 6 million students. Local education agencies (LEAs) play a vital role in fighting climate change and protecting the environment for future generations.

Local education agencies are required to maintain mandatory commercial recycling and organics recycling (compost) programs, including ensuring that schools have properly labeled recycling and composting containers to collect bottles, cans, paper, cardboard, food waste, and other recyclable materials. SB 1383 builds upon these efforts by expanding the definition of organic waste to include food scraps, landscape and pruning waste, fibers, wood, and more.

School staff and administrators must subscribe to organic waste collection service and educate employees and students about organic waste prevention.

Staff and administrators must periodically:

School staff and administrators must provide containers to collect organic waste and recyclables in all areas where landfill containers are provided, except in restrooms.

However, a school is not required to provide an internal collection container if a specific material type is not generated in a particular room (e.g., food waste in a classroom). Containers must conform to the proper color and labeling requirements.
