【 摘 要 】

Japan has been a leading country who has taken on emission reduction measures of fluorocarbon gases. This paper introduces experience and modality of Japan's fluorocarbon control policy, particularly of the latest revision enforced by Act on Rational Use and Proper Management of Fluorocarbon. The act obliges owners of air conditioning/refrigeration units (here in after "equipment") deal with fluorinated gases emissions both in usage phase and in decommissioning phase. This paper explains modality of the provisions stipulated in the act focusing on stakeholders of building, with explanation of supplemental efforts made voluntarily. It is explained that supplemental measures are vital in addition to the obligation, for the sake of ensuring the fluorocarbon emissions reduction measures completed. Besides, this paper explains in regard to expected greenhouse gases reduction by refrigerant leakage prevention in usage phase. Under Japan's fluorinated gases control policy, owners of equipment must conduct inspection of each unit once a designated period to prevent leakage of fluorinated gases, as well as calculating and reporting seepage emissions of fluorinated gases used for refrigerant to government if it is more than a threshold. This obligation makes owners of equipment conscious of leakage emissions of fluorinated gases used for refrigerant, which result in leakage prevention. As effects of leakage prevention of fluorinated gases in building sector in Japan, both the estimated significance of emission reduction in retailing sector and results of the policy implementation in building sector are shown. Japan's fluorocarbon emission control policy has been characteristic in world. Sharing the experience could contribute to setting up further HFCs emissions reduction measures, especially in Asia region where emissions of fluorinated gases used for refrigerant are expected to increase.
