Mitsubishi Motors Corporation has won a US Environmental Protection Agency (EPA) 2007 Climate Protection Award in recognition of its contribution to protection of the global climate for the power-saving automotive air conditioning unit that it developed in collaboration with Mitsubishi Heavy Industries.

The EPA cited the significant reductions in power consumption the unit achieves as a result of improvements to the air conditioner itself and to its control system. In the joint project, MHI developed a new compressor and other components and undertook developmental testing of the system. MMC, for its part, fitted the air conditioner to an Outlander SUV model and boosted the operational efficiency of the system by making improvements to the vehicle body and to the control system and was also responsible for practical utility testing.

The power-saving automotive air conditioner clears the 30% improvement target in air conditioner system efficiency called for under the improved mobile air conditioning (I-MAC) research programme launched by the Society of Automobile Engineers (SAE) and the EPA in 2004.

The EPA awards are made to individuals, bodies, corporations and governmental organisations in recognition of exceptional technological achievements in the field of climate protection.

The award system was introduced in 1998 following the adoption of the Kyoto Protocol in 1997.

MMC will introduce an Outlander model fitted with the power-saving air conditioner in North America this autumn.
