The California Environmental Quality Act (CEQA) is a California statute passed in 1970 and signed in to law by then-Governor Ronald Reagan, shortly after the United States federal government passed the National Environmental Policy Act (NEPA), to institute a statewide policy of environmental protection. CEQA does not directly regulate land uses, but instead requires state and local agencies within California to follow a protocol of analysis and public disclosure of environmental impacts of proposed projects and, in a departure from NEPA, adopt all feasible measures to mitigate those impacts. CEQA makes environmental protection a mandatory part of every California state and local (public) agency's decision making process. It has also become the basis for numerous lawsuits concerning public and private projects. CEQA has been criticized for being "abused" (used for reasons than environmental ones) to block, downsize, delay, or gain other concessions from new development. CEQA has even been used to block or delay projects that have positive environmental impacts, such as solar plants, wind turbines, bike lanes on pre-existing roads, and denser housing. One study found that 85% of CEQA lawsuits were filed by organizations with no record of environmental advocacy and 80% of CEQA lawsuits targeted infill development. CEQA has also been used to block homeless shelters and affordable housing projects, and unions have used CEQA lawsuits or threats thereof to force developers to use union workers. Policy The CEQA statute, California Public Resources Code § 21000 et seq., codifies a statewide policy of environmental protection. According to the act, all state and local agencies must give major consideration to environmental protection in regulating public and private activities, and should not approve projects for which there exist feasible and environmentally superior mitigation measures or alternatives. CEQA process overview CEQA mandates actions all state and local agencies must take to advance that policy. Specifically, for any project under CEQA's jurisdiction with potentially significant environmental impacts, agencies must identify mitigation measures and alternatives by preparing an Environmental Impact Report, and must approve projects with feasible mitigation measures and the environmentally superior alternative. The California Natural Resources Agency promulgates the CEQA Guidelines, California Code of Regulations Title 14 § 15000 et seq., which detail the protocol by which state and local agencies comply with CEQA requirements. Appendix A of the CEQA Guidelines summarizes this protocol in flowchart form. CEQA originally applied to only public projects, but California Supreme Court interpretation of
