Clearinghouse of Non-CO₂ Greenhouse Gas Emission Control Technologies

Background:

This is the home page for ARB's Clearinghouse of Non-CO₂ Greenhouse Gas Emission Control Technologies. You will find on these pages useful information to help you research decisions regarding available technologies and approaches for controlling emissions of greenhouse gases other than carbon dioxide, such as methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF₆) and black carbon (BC).

This index of technologies is based on the report entitled (click link to download):

"Clearinghouse of Technological Options for Reducing Anthropogenic Non-CO₂ GHG Emissions from All Sectors" (pdf - 2,588 KB)

and follows that report's organization, as indicated by level of indentation. Chapter numbers refer to chapters in body of that report, and links provide the information available at the indicated level of organization. Please review the report for additional information.
