7. Conclusions
1 To reduce ODS emissions originating from fluorocarbons1. To reduce ODS emissions originating from fluorocarbons and GHGs, NEDO has carried out many projects based on the roadmap prepared by the Japanese government for
l 20over nearly 20 years.
2. NEDO is not only developing different kinds of refrigerating y p g g gand air conditioning systems using natural refrigerant (CO2, ammonia, air, etc.). It also is assisting in the practical application of freezer showcases using CO2-basedapplication of freezer showcases using CO2 based refrigerant in supermarkets and convenience stores through research, development and demonstration activities.
3. NEDO is carrying out technology development of commercial air conditioning equipment that uses low-GWP refrigerant (CO2, HFO-123yf, HFO-1234ze, etc.) and is evaluating the performance and safety of the refrigerant. We also consider that the results will be embodied inWe also consider that the results will be embodied in amendment of laws in the future .
