Global warming is a huge challenge for the survival of humanity. SF6 as a super greenhouse gas is facing the end of being eliminated. (CF3)2CFCN and C5F10O as the substitute for SF6, the evaluation of the impact on climate change depends on the calculation of GWP. In this work, we introduced and summaried the calculation and testing principles of GWP. Further, the radiative efficiencies of (CF3)2CFCN and C5F10O were calculated by using the revised Pinnock curve based on the Oslo line-byline (LBL) model and density functional theory. Finally, we calculated the the global warming potential of (CF3)2CFCN and C5F10O based on the experimental values of the atmospheric lifetime and radiative efficiencies. The results show that the contribution of (CF3)2CFCN to climate change is significantly lower than that of SF6.
