• Clearinghouse of Non-CO2 GHG Control Technologies - The California Air Resources Board (ARB) has posted a clearinghouse of non-CO2 GHG control technologies on its website. The technologies can be used to reduce emissions of non-CO2 greenhouse gases, such as methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride and black carbon.

Construction Permit Application Assistance

Starting on July 2, 2007, construction permit applications must include potential greenhouse gas emissions for the project. Applications received without this information will be considered incomplete and the permit(s) cannot be issued until the information has been received. Please note that the Linn County and Polk County air permitting programs are also subject to the same requirements. The following form (Form GHG) has been developed by the Department for the reporting of Greenhouse Gas Emissions for projects:
