Global Warming Prevention : Activities in FY2007
Olympus emits greenhouse gases as a result of the use of energy in its business operations, and also from the use of CFC substitutes.One of our most important tasks is the suppression of greenhouse gas emissions to prevent global warming, which is becoming more serious. We are now energetically working on the prevention of global warming.
Results for FY2007
Energy-related CO2 emissions (per unit of sales) reduced by 39% compared with FY1990 level
Energy-related CO2 emissions (per unit of sales) were reduced by 39% relative to the FY1990 level. Though energy consumption was higher because of increased production, we continued our efforts to reduce CO2 emissions through various initiatives in the FY2007. These included improvements to clean room operating methods at the Utsugi Research Institute, and the conversion of facilities at the Tatsuno Plant to operate on LPG, which emits less CO2, instead of fuel oil. Of particular importance was the acceleration of initiatives, including an energy conservation survey, at our plants in China, which account for around 50% of CO2 emissions from all Olympus Group manufacturing sites.
At the global level, we aim to achieve our current targets for emissions per unit of sales by fiscal 2010. We will also work to reduce total CO2 emissions by taking a more aggressive approach, including intensive energy conservation measures targeting production processes, and the use of clean energy resources.
Change in Emissions of CO2 from Energy Systems and CO2 Emissions per unit Sales
Note1: Change of all manufacturing sites only
Note2: The Greenhouse Gas Protocol conversion coefficients are as follows.
Japan: Calculations for items other than electric power were based on the conversion coefficient stipulated in the Greenhouse Gas Emission Methodology and Reporting System. Conversion coefficients published each year by the Federation of Electric Power Companies of Japan were used for electric power. The electric power figures for FY2007 were calculated using the FY2006 coefficient.
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 down 48% year-on-year
Some of the propellants that we use in dust-blowing systems, as cleaning agents, and in semiconductor etching processes are classified as greenhouse gases. In FY2007, we achieved our target for the reduction of non-energy greenhouse gas emissions with a 48% year-on-year reduction to the equivalent of 3,027 tons of CO2. The use of cleaning agents was reduced by 37% year-on-year through conversion to alternative gases with lower greenhouse coefficients. Also, the amount of greenhouse gases in gases used in semiconductor etching processes was significantly reduced (86% year-on-year) through the installation of substance removal systems.
Change in CO2 emissions from non-energy-systems
Note3: Calculated using the figures stipulated in the enforcement order for the Law Concerning the Promotion of the Measures to Cope with Global Warming
