3. Industry's commitment to environmental issue6/81) JRAIA’s position on Japanese Government Environment Policy

JRAIA will work towards the realization of Carbon Neutrality while considering S+3Es.
① HVAC&R industry’s basic stance towards Carbon Neutrality : Aim to expand the use of heat pump technology and products that are also highly efficient from theperspective of utilizing renewable energy.
 Use the designated products to reduce HFCs as much as possible and explore the possibility of safe useof lower GWP, e.g. “Green refrigerants” such as natural refrigerants and ultra low-GWP refrigerants.

② Direction of response to Carbon Neutrality in HVAC&R sector： Basic principle : S + 3Es

Balanced target setting and target-driven activities on Safety plus Environment performance, Energy
efficiency and Economic feasibility are important.
 Safety(S) : Ensure safety together with users(consumers), installers and other relevant stakeholders
 Environment performance(E) : Convert to lower GWP refrigerants from an environmental point of view.
 Energy efficiency(E) : Improve the efficiency of equipment systems from the perspective of improving
energy efficiency (directly linked to the reduction of CO2 emissions).
 Economic feasibility(E) : A reasonable price (cost) that balances the above three items is essential topromote market diffusion.
