Q3. What is the effective date of the rule?
Note: The Cal e-GGRT help system includes general instruction on using the California GHG reporting tool. However, the help system may not explain differences between California and U.S. EPA reporting requirements. Please refer to the ARB reporting website for California-specific reporting requirements and additional help.

The effective date is 60 days after the rule is published in the federal register. The Mandatory Reporting of Greenhouse Gases Rule was published in the federal register on October 30, 2009 and thereby the effective date is December 29, 2009.
