The Ozone Layer Protection Act (Law No. 53 of May 20, 1988) aimed to control the production and import of designated CFCs under the regulations and endeavor to shift such CFCs to alternative ones that do not cause depletion of the ozone layer.
The Ozone Layer Protection Act was amended in July 2018 and will enter into force in April 2019.
Under the revised Ozone Layer Protection Act, Japan will accelerate the shift of alternative CFCs to green coolants, refrigerants that do not deplete or negatively impact the ozone layer. The amendment sets a ceiling on the production and consumption of HFCs, set guidelines to allocate production quota per producer as well as regulate exports and imports. The consumption levels are projected to be below the Kigali cap at least until 2029, when the Kigali cap lowers significantly.
