*Southwire uses a subscription software solution to consolidate GHGs (CO2, CH4, N2O, HFCs, PFCs, SF6 and NF3) into CO2e. Global Warming Potential (GWP) values for natural gas, propane, etc. are based on the IPCC Fifth Assessment Report, 2014 (AR5). All sites are under operational control.
†Our subscription software consolidates GHGs (CO2, CH4, N2O, HFCs, PFCs, SF6 and NF3) into CO2e. Factors in the system are either based on US EPA eGRID factors (electricity) or in-country equivalent or the best estimate for international sites; GWP values for natural gas, propane, etc. are based on the IPCC Fifth Assessment Report, 2014 (AR5). All sites are under operational control.
*Information obtained from utility bills, estimates used where data unavailable; Energy consumption calculated based on 1,025 Btu/cf natural gas (2013 average per US Energy Administration), 91,420 Btu/gal propane (Alternative Fuels Data Center, 2014), 1,054.2 Joules/Btu, 3.6 MJ/KWh
