 One of the biggest issues is leakage from equipment.
 Leakage of both at disposal and in use are more than 80%.

7. JRAIA’s Vision and Activities on Environmental Conservation
 JRAIA has 3 main pillars.
 Each pillar links the laws( yellow bars) related to each factors.

EQUIPMENT
Energy Saving
Emission control on aCO2 basis

REFRIGERANTS
Direct Emission Control· Promotion of recovery· Measures against leakage(proper management ofrefrigerants)· Reduction of amountcharged into equipment

ALTERNATE
REFRIGERANTS
Acceleration to shift
to new refrigerants· Use of non HFC
refrigerants· Research of low GWP
