CFC reduction measures in the cleaning process 1991 In Japan

 Japan was 132,000 tons in 1986 and 8 In 1996, 164,000 tons of CFCs were consumed. This was equivalent to about 10% of the world's total consumption. And about half of it was used for cleaning electronic components and other items.

　The reason why Japan is said to be at a disadvantage compared to Europe and the United States in reducing CFC use is that the development of alternatives to CFCs for cleaning has lagged behind the development of other alternatives. About 40% of CFCs used in Europe are for aerosol applications, and it was relatively easy to switch to LPG (liquefied natural gas) and CFC substitutes. In the U.S. as well, about 40% is used for refrigerants such as air conditioners, and the amount could be reduced considerably through measures to prevent gas leaks.
