Study is the first to examine social disparities in location of emissions
California law requires 25 percent of the revenue from the state’s cap-and-trade program, designed to limit emissions of greenhouses gases like carbon dioxide, to be invested in measures that benefit disadvantaged communities. But a newly published study by San Francisco State University, the University of California, Berkeley and others comparing emissions before and after the program began in 2013 found that disadvantaged communities are not yet benefitting — and have actually seen an increase in pollutants.
