As directed by SB97, the Natural Resources Agency adopted Amendments to the CEQA Guidelines for greenhouse gas emissions on December 30, 2009. On February 16, 2010, the Office of Administrative Law approved the Amendments, and filed them with the Secretary of State for inclusion in the California Code of Regulations. The Amendments will become effective on March 18, 2010. 


The Natural Resources Agency would like to express its deep appreciation to the numerous organizations, agencies and individuals that participated in the development of the CEQA Guidelines Amendments since the enactment of SB 97 in 2007. Your advice, comments and support contributed to the development of amendments that will prove practical and useful, and which will encourage consistency in the analysis and mitigation of greenhouse gas emissions. That so many dedicated their time and energy over such a long period of time is a testament to the importance of these CEQA Guidelines Amendments. 

The adopted text of the Amendments, as well as key documents from the Agency's rulemaking process, are provided below. Text revisions are marked as follows: new additions are underlined and deletions are indicated by strikeout.
