By introducing cogeneration systems, Sanyo's factories and large-scale buildings utilize the exhaust heat generated through independent power generation to produce steam and hot water, which is then used for cooling and warming of production processes and facilities. The usage of the exhaust heat improves energy-use efficiency in production processes and thus contributes to energy conservation.
SANYO Semiconductor Co., Ltd. and SANYO Semiconductor Manufacturing Co., Ltd. are promoting the introduction of energy-saving equipment and facilities into their manufacturing sites, including turbo freezers, high-efficiency transformers, and free cooling systems. A free cooling system is one that allows water that is normally sent through a mechanical chiller during the summer, to be chilled by outside air with a cooling tower during the winter and cooler months. Since the chiller is not used in the winter, a lot of energy can be saved.

SANYO Electric Logistics Co., Ltd. offers logistics solution services for storage, loading, shipping, and delivery using the 3PL system^*1. To reduce greenhouse gas emission, the company aims to realize comprehensive and consolidated distribution, and to do so utilizes the network that connects its bases and relevant companies to practice shared delivery and round-trip transportation which transports goods both outbound and inbound. The Sanyo group reduced its annual CO₂ emissions by about 700 tons in fiscal 2008, by promoting a modal shift from trucking to rail and sea transport, for the shipping of products from Tottori and Kanto (Gunma), where the company’s main manufacturing facilities are located, to Hokkaido and Kyushu. Sanyo’s Commercial Solutions Company has constructed a modal shift transport system together with Yamato Transport Co., Ltd., for the shipping of large commercial products such as kitchen equipment and refrigerated showcases between Koshigaya City, Saitama and Fukuoka City, Fukuoka.
The Sanyo group also reduced its annual CO₂ emissions by about 1,300 tons in terms of total effect, by reducing the use of truck transport within Japan, through the unloading of imported products at ports closest to the regions where they are consumed.

*1 3PL: 3rd Party Logistics. Practice of outsourcing services in which all corporate logistics functions are commissioned to one logistics agent.

The Sanyo Group intensively promotes energy-saving activities at the headquarters buildings, Sanyo office buildings, and leased buildings, such as setting air-conditioner thermostats at the specified temperature (28°C or higher for summer and 20°C or lower for winter), practicing "Cool Biz" and "Warm Biz," and turning off air conditioners, lighting, and monitors when not in use. Through air-conditioning control during summer (June - October) and winter (December - March), estimated CO₂ reduction of approximately 2,000 tons is expected.

Further, in fiscal 2008 Sanyo again responded to the “CO₂ Reduction/Light Down Campaign” and turned off 42 neon signs on buildings of the Sanyo Group. From fiscal 2009, the company expects to create an annual CO₂ reduction effect of about 270 tons, by turning off 33 large neon signs after 8 p.m., throughout the year.

The Sanyo Group is striving to develop and disseminate clean energy technology using solar power and has introduced solar power generation systems at 10 major facilities in Japan to play a role in reducing CO₂ emissions. Solar Ark, Sanyo's large-scale photovoltaic power generation facility in Gifu Plant, which started operation in December 2001, has 5,046 solar panels covering the exterior surface. Its 630kW generating capacity is one of the largest generation capacities in the world, and approximately 590,000kWh was generated in fiscal 2008. The generated power is supplied to the plant via a substation located on the premises.
