The Japan Act on Rational Use and Proper Management of Fluorocarbons became effective in April 2015. It includes measures regarding the promotion of low-GWP/non-HFC alternatives for designated products, the phase-down of HFCs, and the reduction of refrigerant leakage from equipment during use. Manufacturers and importers of HFCs are subject to a phase-down of 40% reduction of HFC use by 2020 and 52% reduction by 2025. Equipment manufacturers have target GWP values set based on the lowest GWP (weighted average by volume) among designated products in the market. There are currently no required GWP targets for fire protection agents.
