Cal e-GGRT Help

Q7. Which greenhouse gases (GHGs) are covered under 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 rule will require reporting of anthropogenic GHG emissions covered under the United Nations Framework Convention on Climate Change (UNFCCC); carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFC), perfluorochemicals (PFC), and sulfur hexafluoride (SF₆), as well as other fluorinated gases (e.g., nitrogen trifluoride and hydrofluorinated ethers). These gases are often expressed in metric tons of carbon dioxide equivalent (mtCO₂e).
