Greenhouse gases, criteria air pollutants, and toxic air contaminants.

The California Global Warming Solutions Act of 2006 designates the State Air Resources Board as the state agency charged with monitoring and regulating sources of emissions of greenhouse gases. The act authorizes the state board to include the use of market-based compliance mechanisms. The act requires the state board to approve a statewide greenhouse gas emissions limit equivalent to the statewide greenhouse gas emissions level in 1990 to be achieved by 2020 and to ensure that statewide greenhouse gas emissions are reduced to at least 40% below the 1990 level by 2030. The act requires the state board, when adopting rules and regulations to achieve greenhouse gas emissions reductions beyond the statewide greenhouse gas emissions limit and to protect the state's most impacted and disadvantaged communities, to follow specified requirements, consider the social costs of the emissions of greenhouse gases, and prioritize specified emission reduction rules and regulations. This bill would additionally require the state board to consider and account for the social costs of the emissions of greenhouse gases when adopting those rules and regulations. The bill would authorize the state board to adopt or amend regulations that establish a market-based compliance mechanism, applicable from January 1, 2021, to December 31, 2030, to complement direct emissions reduction measures in ensuring that statewide greenhouse gas emissions are reduced to at least 40% below the 1990 level by 2030. The bill would authorize the state board to adopt no-trade zones or facility-specific declining greenhouse gas emissions limits where facilities' emissions contribute to a cumulative pollution burden that creates a significant health impact. This bill would require the state board, in consultation with affected air pollution control and air quality management districts, to adopt air pollutant emissions standards for emissions of criteria air pollutants and toxic air contaminants at industrial facilities that are subject to a market-based compliance mechanism. The bill would prohibit the state board from allocating allowances as part of a market-based compliance mechanism to industrial facilities that do not meet the air pollutant emissions standards for criteria air pollutants and toxic air contaminants. This bill would require the state board, in ensuring that statewide greenhouse gas emissions are reduced to at least 40% below the 1990 level by 2030, to adopt the most effective and equitable mix of emissions reduction measures and ensure that emissions reduction measures collectively and individually support achieving air quality and other environmental and public health goals.
