The JAL Group has announced it will voluntarily participate in trials of a Japan-only emissions trading scheme set up by the Japanese government. The trial scheme runs from FY2008 to FY2012, the financial years ending March 31. Companies that volunteer to participate in the scheme must set themselves CO2 emission reduction targets for their business operations in Japan for every financial year during the 5-year period. Targets are submitted by each company for approval by the Japanese government. Companies that manage to achieve their CO2 emission reduction targets and exceed them can trade credits with other companies in the scheme that have not managed to meet their own targets. JAL has set itself for each fiscal year a target for cutting the CO2 emissions per available seat kilometre (ASK) of its Japan domestic fleet, when compared to 1990 levels. This includes all domestic operations by JAL and JAL Group airline subsidiaries. The airline group is targeting a 16 per cent cut in CO2 emissions per ASK of its domestic fleet each year up until FY2012. The percentage targets will be calculated by comparing the base fiscal year of 1990 to the average CO2 emissions per ASK of three-year periods up to and including each financial year.
