Acting on a December 2016 Executive Order of Governor Gerry Brown, the California Office of Environmental Health Hazard Assessment released the first in a series of reports which will examine the impact of the state’s climate change programs on communities designated as “disadvantaged”.  The February report,  Tracking and Evaluation of Benefits and Impacts of Greenhouse Gas Limits in Disadvantaged Communities: Initial Report   measuring the effects of  the Air Resources Board’s Cap-and-Trade Program, which regulates greenhouse gas emissions from industrial facilities and other sources.  The report is largely based on 2014 emissions data, and warns that “limited data does not yet allow for comprehensive analysis of the impacts of Cap-and-Trade on disadvantaged communities”.   Initial findings however, are that  major industrial facilities are disproportionately located in disadvantaged communities;  there is a moderate correlation between GHG and other air pollutants, with refineries showing the strongest correlation.   California maintains  a planning and enforcement tool,  CalEnviroScreen, the “ first comprehensive, statewide environmental health screening tool” in the U.S.  In late January, California Air Resources Board   announced the appointment of its first Assistant Executive Officer for Environmental Justice, with a mandate to ensure that environmental justice and tribal concerns are considered in air pollution policy-making and decision- making.
