The Air Resources Board (ARB) is working on reducing greenhouse gas (GHG) emissions from multiple sectors of California’s economy, as part of the implementation of AB 32, the Global Warming Solutions Act. Grouping these GHG sources into major “economic sectors” allows ARB to better define, organize, and control them. This page contains information regarding sector control measures, reduction strategies, working groups, protocols and other pertinent information. These activities are a continuing process so this page will be updated and hyperlinked as new information becomes available.
The agriculture sector includes on-farm GHG emissions from animals and from crop management. On-farm sources include GHGs from animal wastes, energy use, crop residue burning, livestock, soil management practices, and anaerobic decomposition of organic matter. Follow the links below for more detailed information.
The energy sector includes two overarching strategies for obtaining GHG reductions from electricity and natural gas that reduce energy use, and supply-side strategies that lower GHG emissions associated with electricity generation. Energy efficiency will be California’s most effective tool for achieving GHG reductions and has made strong commitments to renewable energy. Follow the links below for more detailed information.

California’s forests play a critical role in the State’s carbon balance, with the unique capacity to remove CO2 from the air and store it long-term as carbon. The forest sector is the only sector that provides a net removal of GHGs. Below you can find more information related to forest protocols and work groups.
High Global Warming Potential (GWP):
This sector consists of a broad range of sources that emit GHGs that have hundreds to thousands of times the climate impact as CO2. High global warming potential substances are largely used as refrigerants in stationary and mobile source air conditioning and refrigeration. However, high GWP gases are also used as foam-blowing agents, in electrical transmission, as fire suppressants, and in various consumer products. Follow the links below for more detailed information.

Local Initiatives and Land Use:
State, regional, local, and non-governmental stakeholders must work together to prioritize and create policies, programs, incentives, guidance, and funding to assist local actions to help meet California’s climate change goals. These will be developed on an ongoing basis. Currently, there are many supporting agencies and programs available to assist local governments in their efforts to reduce GHGs. Below you will find various links to activities related to local actions.

Industry and Manufacturing:
The industry and manufacturing sector covers a broad and diverse range of small and large industrial sources. Maintaining the economic health of California’s business and industry while continuing to reduce criteria, toxic, and GHG emissions is vitally important. Most emission reductions from the industrial sector will be realized through the cap-and-trade program which will include large industrial sources. Below you can find industrial GHG reduction activities.
Oil & Gas/Refining:
This sector is a subset of the industry sector. ARB is in the process of developing refinery and oil & gas measures. Below you can find GHG reduction activities related to oil & gas, refining and fuels.
The transportation sector is integral to the people and economy of California. To achieve GHG emission reduction goals, it is vital that we build on our past successes in reducing criteria and toxic air pollutants from transportation and goods movement activities. GHG emission reductions will come from cleaner vehicle technologies, lower-carbon fuels, and reduction of vehicle use or vehicle miles traveled. Follow the links below for more detailed information.

Issues related to managing and utilizing California's waste resources are diverse and interconnected. Decisions addressing these issues will directly impact how quickly we achieve greenhouse gas (GHG) and waste reduction goals. The Waste Management Sector (Waste Sector) includes all municipal and commercial solid waste-related activities (e.g., collection, processing, recycling, remanufacturing, treatment, or disposal) from generation to final disposition of the material within California. This sector includes market development programs such as the State's environmentally preferable purchasing program. Follow the link below for more detailed information.
Water use requires significant amounts of energy. Approximately one-fifth of the electricity and one-third of the non-power plant natural gas consumed in the state are associated with water delivery, treatment and use. The water sector targets reducing energy requirements associated with providing reliable water supplies and reducing the amount of non-renewable electricity associated with conveying and treating water. Other activities focus on providing sustainable funding for implementing these actions. Follow the links below for more detailed information.
