Abstract: HFC-134a has been widely used in China’s mobile air conditioning sector and thus ranks the first in the contribution of Chinese HFCs emissions that is intentionally produced and applied. Relevant legislation and regulations have been promulgated by the European Commission and United States in order to control the consumption and emission of fluorinated greenhouse gases, including HFC-134a. Choosing alternative technologies with low global warming potential (GWP), China’s mobile air conditioning will have huge emission mitigation potential in the future. Furthermore, with the diversity in demand of mobile air conditioning system, and with both the advantages and disadvantages existing in the current alternatives, such as HFO-1234yf, HFC-152a, and CO2, it should be made that comprehensive considering of economic cost, marketization feasibility and safety risk of adopting the alternative technologies and as well as environmental standards. Developing HFC-134a phase-out policy and positively promoting research and application of substitute and alternative technologies should be done in the future, in order to actively respond to the action of accelerating the elimination of HFC-134a by international community, and to implement the action of phasing down global HFCs announced in the “US-China Joint Announcement on Climate Change”in 2014.

Key words: mobile air conditioning, HFC-134a, alternative technology, phase-out policy
