Results and discussion
Any other information on results incl. tables
See attachment for infrared (IR) spectrum of HFPO. Average cross-section in the absorbance range of ozone (1000 - 1100 cm-1) was >0.148, indicating that the radiative forcing does not need to be corrected for confounding by ozone absorbance. Instantaneous radiative forcing was used directly. The instantaneous radiative forcing is 0.260 W∙m-2∙ppbV-1. Assuming an atmospheric lifetime range of 90 years, the 100-year GWP of HFPO is 6200.
Applicant's summary and conclusion
- Conclusions:
- The 100-year GWP of HFPO is 6200.
- Executive summary:
Potential effects of HFPO on climate were addressed by calculation of 100-year integrated global warming potential (100-year GWP). A high-resolution infrared spectrum was taken using a protocol following EPA method 320. Integrated IR cross-section and radiative forcing were calculated using the approach of Pinnock et al (J. Geophys. Res., 100, 23227-23238). Atmospheric lifetime was determined in this study to be 90 years (reported elsewhere in this dossier, see section "Phototransformation in air"). GWP was calculated for this study summary using the WMO 1998 model with updated CO2 response and forcing. The integrated instantaneous radiative forcing was 0.260 W∙m-2∙ppbV-1. The 100-year GWP is 6200. A 20-year GWP of 6400 was also determined.
No testing guideline has been promulgated to determine global warming potential. However, the infrared cross-section data were collected according EPA method 320, and the radiative forcing and GWP were calculated by methods accepted by IPCC. Therefore, this study is classified as reliable without restrictions.
