Subpart A of Part 98 - Global Warming Potentials by Reporting Year (100-Year Time Horizon)
In addition to the global warming potentials (GWPs) from Table A-1 that should be used for reporting for Reporting Year (RY) 2014 onwards, the tables below include the GWPs that should be used for prior Reporting Years (RY2013 and RY2010-12). Table A-1 includes GWPs for the following classes of compounds:
- Chemical-Specific GWPs
- Fully Fluorinated GHGs
- Saturated Hydrofluorocarbons (HFCs) With Two or Fewer Carbon-Hydrogen Bonds
- Saturated Hydrofluorocarbons (HFCs) With Three or More Carbon-Hydrogen Bonds
- Saturated Hydrofluoroethers (HFEs) and Hydrochlorofluoroethers (HCFEs) With One Carbon-Hydrogen Bond
- Saturated HFEs and HCFEs With Two Carbon-Hydrogen Bonds
- Saturated HFEs and HCFEs With Three or More Carbon-Hydrogen Bonds
- Fluorinated Formates
- Fluorinated Acetates
- Carbonofluoridates
- Fluorinated Alcohols Other Than Fluorotelomer Alcohols
- Unsaturated Perfluorocarbons (PFCs)
- Unsaturated Hydrofluorocarbons (HFCs) and Hydrochlorofluorocarbons (HCFCs)
- Unsaturated Halogenated Ethers
- Fluorinated Aldehydes
- Fluorinated Ketones
- Fluorotelomer Alcohols
- Fluorinated GHGs With Carbon-Iodine Bond(s)
- Other Fluorinated Compounds
