Enacted by	California State Legislature
Introduced by	Arnold Schwarzenegger?
Date signed	2006
Status	in force

Assembly Bill 32 (Global Warming Solutions Act of 2006) established a statutory framework to reduce greenhouse gas emissions in California. The law set economy-wide limits and directed state agencies to design regulations, market mechanisms, and reporting systems to achieve those limits. It has influenced policy debates involving United States Environmental Protection Agency, California Air Resources Board, European Union Emissions Trading Scheme, and stakeholders across energy sector and transportation.

Background and Enactment

Assembly Bill 32 arose amid national and international developments including the Kyoto Protocol, debates in the United States Congress, and state-level initiatives like California Global Warming Solutions Act. The measure was enacted within the political context of the 2006 United States elections and policy leadership claims by Arnold Schwarzenegger alongside legislative actors in the California State Assembly and California State Senate. Legislative compromise reflected input from advocacy groups such as Natural Resources Defense Council, Sierra Club, and industry representatives including Pacific Gas and Electric Company and Chevron Corporation. The law paralleled initiatives in jurisdictions like the European Union and British Columbia, creating linkages to international carbon markets and regulatory design debates seen in the Regional Greenhouse Gas Initiative.

Key Provisions and Targets

The statute codified a statewide emissions cap aimed at returning California to 1990 greenhouse gas levels by 2020 and directing further reductions thereafter. It authorized the California Air Resources Board to adopt regulations, including market-based mechanisms, compliance schedules, and reporting requirements. The act required preparation of a Scoping Plan outlining measures across sectors such as electric power industry, automotive industry, agriculture, and industrial manufacturing. It established enforcement authorities and directed coordination with agencies like the California Energy Commission and California Public Utilities Commission.

Implementation and Regulatory Framework

Implementation depended on rulemaking by the California Air Resources Board, which issued a Scoping Plan and subsequent amendments to develop cap-and-trade, fuel standards, and reporting systems. Regulatory tools included mandatory emissions reporting facilitated through registries, compliance instruments interoperable with systems like the Western Climate Initiative, and linkage agreements with programs such as the Quebec cap-and-trade program. The law required integration with programs overseen by United States Environmental Protection Agency where federal preemption and cooperative federalism considerations emerged. Administrative procedures involved environmental review under California Environmental Quality Act and economic analyses by agencies such as the Legislative Analyst's Office (California).

Emissions Reduction Measures and Programs

Key programs implemented under the statute included a statewide cap-and-trade system administered by California Air Resources Board, the Low Carbon Fuel Standard influenced by work at the California Energy Commission, vehicle emissions standards aligned with California Air Resources Board regulations, and energy efficiency programs involving Pacific Gas and Electric Company and Southern California Edison. Sectoral measures addressed California Department of Food and Agriculture practices, California Department of Transportation planning, and industrial emissions controls informed by agencies like United States Department of Energy. Market elements enabled allowances, offsets, and auction mechanisms interacting with entities such as Wall Street firms and regional utilities.

Legal Challenges and Litigation

Litigation followed enactment and regulation, with challenges brought by trade associations, municipal entities, and industry groups to agencies' rulemaking authority and market design. Cases reached state courts and intersected with federal litigation concerning Clean Air Act preemption and United States Supreme Court precedents. Plaintiffs included utilities and businesses opposing aspects of cap-and-trade, while defendants comprised California Air Resources Board and state officials defending statutory interpretation. Outcomes in appellate rulings and settlements shaped rule adjustments and procedural practices for regulatory adoption.

Economic and Environmental Impacts

Evaluations by academic institutions and agencies assessed the law’s impact on emissions trajectories, air quality, and economic metrics such as employment, gross state product, and sectoral competitiveness. Studies from University of California campuses, think tanks like RAND Corporation, and agencies including the California Environmental Protection Agency examined co-benefits such as reductions in particulate matter and ozone precursors, and costs implicated in energy prices and compliance expenditures. The program influenced investment in renewable energy firms, grid modernization involving California Independent System Operator, and innovation among automakers like Tesla, Inc. and legacy manufacturers adapting to fuel and emissions standards.

Criticism and Legislative Developments

Critiques emerged from conservative policymakers, business groups, and some environmental justice advocates over allowance allocation, offset integrity, and localized pollution burdens. Legislative responses included amendments, funding authorizations, and oversight hearings in the California State Legislature, with proposals to refine market mechanisms and direct revenue toward programs administered by agencies such as the California Climate Investments initiative. Subsequent legislative acts and ballot measures have interacted with the original statute, prompting ongoing debates among entities like Public Advocates Office (California), California Chamber of Commerce, and community organizations representing frontline communities.
