The Ministry of Economy, Trade and Industry of Japan (METI) and the New Energy and Industrial Technology
Development Organization of Japan (NEDO) have been subsidizing research to obtain basic information on
mildly flammable refrigerants, since 2011. In addition, a research committee was set up by the Japan Society of
Refrigerating and Air Conditioning Engineers to assess the risks associated with mildly flammable refrigerants.
The Japan Refrigerating and Air Conditioning Industry Association and the Japan Automobile Manufacturers
Association are presently conducting definitive risk assessments, and the results are being discussed by the research
committee. This report is a brief introduction to the 2012 progress report.
