This paper describes the comparison of the total equivalent warming impact (TEWI) of R744 and R134a mobile a/c systems. TEWI calculations were performed using experimental results obtained at typical idling and driving conditions instead of model predictions as in the published literature. The results show that for most of the regions in Europe, Japan and the US, the R744 system has a much lower TEWI than the R134a system that was tested.
