| 摘要： | This study provides a first-of-its-kind, mass-based measurement of R134a emissions from heavyduty MAC systems. This groundbreaking effort also collected key information regarding the characteristics of these systems, and provides a foundation for improved emission inventories and for continued reduction of GHG emissions from the heavy-duty vehicle sector in both California and throughout the United States. R134a is one of the most common refrigerants used in mobile air conditioning (MAC) systems today, and is a powerful greenhouse gas that may contribute to climate change. Specifically, R134a (1,1,1,2-tetrafluoroethane) has a global warming potential (GWP) of 1,300. ARB has estimated that total R134a emissions from all MAC systems in California (including light-duty vehicle systems) came to approximately 4 million metric tons of CO2-equivalent (CO2E) in 2004. / Supplementary Notes: Sponsored by California State Air Resources Board, Sacramento.
