The California Supreme Court was asked by the Center for Race, Poverty and the Environment along with other environmental justice groups to terminate the proposed greenhouse gas emissions cap-andtrade program. The advocates are interested in seeing the state Supreme Court review an appellate court decision which permitted the program to proceed, after a trial court injunction had halted implementation. Environmental justice groups say that the program would result in higher pollution on low-income communities. Environmental groups oppose specific measures in the cap-and-trade program, particularly the trading of off-sets which they believe would unfairly impact low income communities and communities of color. Also, the Center for Biological Diversity, Global Justice Ecology Project, and other groups sent a letter to Governor Jerry Brown (D-CA) on July 28 asking the governor to reject the current cap-and-trade plan due to its potential effects on low income communities.
