１－1．Control of fluorocarbons○Measures for production, consumption and import of CFCs and HCFCs have been taken
for protecting Ozone layer and proper implementation of the Montreal Protocol by theOzone Layer Protection law since 1988.
○Production and consumption of ODSs other than HCFCs have been phased-out by
2005. HCFCs such as R22 will be phased-out by 2020.
○However, the Montreal Protocol does not require prohibition use of those equipmentusing HCFCs, and they will be used even after 2020.

１－2．Stock increase of HFCs
○Stocked fluorinated gases have been increased in the market as CFCs converted to thealternatives since 2000 and which is a main cause of emission increase of HFCs.
○Immediate action on reduction of the stocked fluorinated gases in the market will beneeded by converting to low-GWP and/or non-HFCs.

2-1 Overview○ The ozone layer protection law was revised on July 4, 2018,
and announcement (Promulgation) was done.
○ This legal revision might fit in with Kigali amendment.
○ Revised ozone layer protection law is going to enforce fromthe day when Kigali amendment in Montreal Protocol comes
into the force.
○ A ratification country of Kigali amendment were up beyond
39, and it will be carried out from January 1, 2019.

２－３．Reduction obligation under the amendment○The amendment to the Montreal Protocol imposes mainly reduction on its calculated levelof production and consumption (production + import – export) HFCs under certain
amount.
○For the developed countries including Japan, reduction from the baseline (average 20112013) will commence in 2019 and phase down to more than 70% after 2029 and beyond.
○ Japan will be in compliance with the reduction steps by 2025 according to the estimatedamount of use indicated below.

２－４．Procedure （expected）
Japanese Baseline setting process
Baseline has to be calculate from Production, Import and Export of averageamount of 2011-2013
1. July-August
Ministry of Economy Trade and Industry (METI) issued an order to datacollecting from HFC’s Producers, Importers and Exporters report of theirhandled HFC’s from 2011 to 2013. They have to report to METI until 1 ofAugust.
2.August-September
METI will calculate the baseline from these collecting reports, and refer tothe Industrial Structure Council and the Central Environment Council.
Japan will decide the Baseline by GWPton and reducing rate of HFC’s.

２－４．Procedure （expected）
Set Baseline for individual companies
October - November
METI will consult with the every HFC’s manufactures, importers andexporters. And they will report of handled HFC’s quantities from 2011 to2018. And also they will declare of GWP amount that is average of
selected arbitrary consecutive 3 years from 2011 to 2018 and apply tomake it the baseline of the company. METI should calculate all companies
declared amount.
December
METI will set the baseline and notice to each company. After that METI
gives permission of manufacturing and import.

Development of optimization technologies and evaluation method
for the next generation refrigerant/refrigeration and air
conditioning equipment
2018 budget 2.2 million US$

Project Purpose / Overview
At the meeting of the Montreal Protocol in October of 2016, Kigali amendment had decided, which had the obligation to stepby-step reduction of production and consumption of HFC, which does not destroy the ozone layer but has a high greenhouseeffect, was resolved . In this amendment, developed countries agreed to reduce HFC by 85% by 2036.
It is difficult to achieve this goal with refrigerant substances (used with air conditioners etc.) using existing CFC substitutes, and
it is inevitable to switch to alternative substances. For next-generation refrigerant substances that compatible with energy
efficiency and low temperature chamber effect, there are issues such as having combustibility, and risk assessment forpractical use is indispensable.

For this reason, we will arrange for a development base for energy-saving refrigeration air conditioning equipment and the likecorresponding to new refrigerant. By establishing a risk assessment method for next-generation refrigerant substances, andconducting air-conditionning equipment evaluation under the practical circumstances.
Achievement goal
By establishing a risk assessment method for the next generation refrigerant and aiming at international standardization in the5 years from FY2018 to FY2022, the next generation refrigerant / refrigeration air conditioning equipment etc. that can achieveenergy saving / low temperature chamber effect etc. We will accelerate development. (In FY2029, we aim to reduce CO2
equivalent to about 1.49 million tons / year by refrigerant conversion.)
