Fuel cell system uses electricity and heat generated by the chemical reaction of hydrogen and oxygen as a household energy source. Because these fuel cells enable concurrent use of electricity and heat and thus offer high energy efficiency, the system can reduce CO₂ emissions by 45% and primary energy consumption by 32% from the average level of conventional energy sources for households (based on research by Panasonic). If all Japanese households were to employ the fuel cell system, the GHG reduction effect would be equivalent to the forestation of a land area 30 times that of the Tokyo Metropolis.^* As of March 31, 2007, approximately 200 systems are in operation since the delivery of the first system to the Japanese prime minister's official residence in February 2005.

• * Based on annual CO₂ emissions from one household (estimated by Panasonic) and the National Census of fiscal 2006 (by the Ministry of Internal Affairs and Communications, Japan)
