Global Warming Prevention : Activities in FY2006
Olympus emits greenhouse gases in the course of our activities, including the use of energy in our production processes. We regard the reduction of greenhouse gas emissions as one of our most important priorities, and we are contributing actively to the prevention of the increasingly serious problem of global warming.
Results for FY2006
Energy-related CO2 emissions (per unit of sales) reduced by 37% compared with FY1990 level
At 105,349 tons, gross energy-related CO2 emissions were marginally higher than the previous year's level due to increased production in China. However, emissions per unit of sales were 37% below the FY1990 level, indicating that we are on track toward achieving our target for FY2010. We are reducing energy-related CO2 emissions in our Japan-based facilities with the aim of reaching our FY2010 target of ±0 relative to the FY1990 level.
We installed new environmental equipment at our Mishima plant in FY2006. And we also continued our day-to-day efforts to reduce energy consumption and improve production efficiency. We will continue working actively to achieve our FY2010 target by saving energy throughout our entire production processes.
Change in Emissions of CO2 from Energy Systems and CO2 Emissions per unit Sales
* Change of all manufacturing sites only
* Greenhouse Gas protocol conversion coefficient is as follows.
Japan: Calculated using the conversion coefficient officially announced by the Ministry of the Environment in 2006 and one announced by the Federation of Electric Power Companies of Japan. Conversion coefficient for electric power in FY2005 employed the coefficient announced in FY2005 instead of one in FY2006.
Overseas: Calculated using the Greenhouse Gas (GHG) protocol conversion coefficient officially announced(http://www.ghgprotocol.org)
Reducing of Non-Energy Greenhouse Gas Emissions
Non-energy CO2 emissions up 8% year-on-year
Some of the propellants we use for dust-blowing systems, in cleaning agents, and in semiconductor etching processes are classified as greenhouse gasses. In FY2006, greenhouse gas emissions for non-energy purposes increased by 8.2% a year-on-year basis to the equivalent of 5,958 tons of CO2.
The use of greenhouse gases in dust blowing systems was reduced by 27.9% year-on-year through volume reductions and conversion to alternative gases with lower greenhouse coefficients. However, there was a temporary increase in the volume of cleaning agents used because of facility adjustments resulting from the relocation of the Sakaki Plant. We are working to achieve our FY2010 target by reducing the amounts used, studying alternative technologies, and developing new technologies, including substance removal systems.
