Japan’s Life Cycle Management Approach
towards 2050 Carbon Neutrality Goal
10th July, 2024

Yuichiro Iseki

Deputy Director, The Office of Fluorocarbons Control Policy, MOEJ

Today’s topics

1. Japan’s HFC emissions year-on-year decrease in 2022
2. Importance of preventing leakage emissions and addressing bank issues
3. IFL’s activities

Time series of HFCs emissions in Japan
 In 2022, HFC emissions posted 46.1 Mt-CO2 eq., 1.6% decrease compared tothe emissions in 2021, after the growing trend since 2004.

Breakdown of HFC emissions
 HFC emissions in 2022 account for 4.1% of total GHG emissions in Japan.
 92.8% of HFC emissions come from the refrigeration.

HFC emissions at life cycle stage
 More than 70% of HFC emissions come from commercial use : 41% of Commercial
Refrigerators, 32% of Commercial AC.
 For the emissions from commercial use, regulated by Fluorocarbon Emissions ControlAct, leakage during use was larger than emissions at disposal.

HFC emission reduction target for 2030
 HFC emission reduction target for 2030: 52% reduction from 2013 level To achieve the target, 69% reduction from 2022 level is required.

Carbon Neutrality by 2050 in HFCs sector in Japan
 Carbon Neutrality by 2050 in HFC sector through promoting its life cycle
management and its phase-down.
 Steady implementation of the Kigali Amendment to the Montreal Protocol.
 Development of low-GWP refrigerants and promotion of natural refrigerants.
 Leakage prevention of fluorocarbons in RAC equipment usage.
 Recovery and proper management of fluorocarbons from RAC equipment.
 International cooperation on fluorocarbons reduction.

About the fluorocarbons bank and IFL
 Global cooling demand is expected to increase dramatically.
 Even with production/consumption control of HFCs under the Kigali Amendment,
HFC emissions are expected to increase to about 2,000 Mt-CO2eq (WMO/UNEP2018).
 Japan-led Initiative on Fluorocarbons Life Cycle Management (IFL) is actively working
to promote Refrigerant Life Cycle Management.
