Description of characterization Factor Converts LCI data to carbon dioxide (CO 2 ) equivalents Note: global warming potentials can be 50-, 100-, or 500-year potentials. Converts LCI data to trichlorofluoromethane (CFC-11) equivalents. Converts LCI data to hydrogen (H+) equivalents. Converts LCI data to phosphate (PO
