The Sanyo Group continues its efforts to reduce environmental impact in business activities with prevention of global warming, waste reduction, recycling of resources, and chemical substance control measures as top priority issues.
With the aim of achieving "Carbon Neutral" status , the Sanyo Group strives to reduce CO2 emissions from all of its business activities, including manufacturing, development, and sales.
For fiscal 2007, gross CO2 emissions were 636,000 tons which is approximately 1% lower compared to the previous fiscal year. However, primarily due to a lower domestic production rate of electronic information equipment, the total CO2 emissions per basic unit of production output for all domestic manufacturing facilities*1 was approximately 4%higher than the previous fiscal year.
Through intensively promoting reduction of energy consumption of manufacturing equipment and air conditioners and efficiency enhancement/streamlining of the production process, Sanyo’s manufacturing facilities work to minimize electricity/fuel consumption and maximize reduction of CO2 emissions in the production process. Further, Sanyo is expediting introduction of fuels causing relatively low CO2 emissions,such as natural gas and LNG (liquid natural gas), and new energy sources, including solar cells, cogeneration (natural gas), and waste heat utilization.
In the future, to address global warming, Sanyo will work to control CO2 emissions by improving energy efficiency in the production process as well as expanding the use of rechargeable batteries and solar cells.
*1 CO2 emissions per Basic Unit of Production Output = CO2 emissions ÷ [gross production output ÷ corporate goods price index published by the Bank of Japan]

* For the CO2 emission factor for electricity purchased each fiscal year, the factor for all power source average (generating end) announced each fiscal year by the Federation of Electric Power Companies of Japan is used. However, since the CO2 emission factor for fiscal 2007 has not been announced yet, the emission factor for fiscal 2006 was temporarily used, which is 0.410 kg-CO2/kWh.
* Data in this table is calculated based on the GHG protocol. It should be noted that the data for each fiscal year is not absolute, because the number of facilities covered varies from year to year due to M&A.
In the manufacturing process of semiconductors and related products, the Sanyo Group uses greenhouse gases other than CO2, such as perfluorocarbon (PFC), sulfur hexafluoride (SF6),and hydrofluorocarbon (HFC). These gases account for approx. 12% of the total greenhouse gas emissions. Sanyo works to reduce consumption and emission of these gases and is expediting their replacement with other substances.
Specifically, regarding PFCs, in the semiconductor cleaning process Sanyo has implemented gas conversion from hexafluoroethane (C2F6) to perfluoropropane (C3F8) which has relatively small Global Warming Potential*2. In addition, Sanyo is proactively considering shifting to carbonyl fluoride (COF2) which causes very little greenhouse gas after reaction. As a result, for fiscal 2007 the emission of greenhouse gases other than CO2 was 5%
