Greenhouse-gas emissions reductions

COSEL aims to reduce its CO₂ emissions by at least 30% in FY 2030 vs. FY 2020.
We launched a project to reduce electric power use, which accounts for a large share of energy consumption, under which we are actively promoting energy-conservation activities (such as adoption of energy-saving machinery and conserving electricity).
We also are making active progress on switching to renewable energy. The R&D Cetner is powered 100% by renewables.
We are making progress on switching air conditioning from GHP air conditioners, which use fossil fuels, to highly energy efficient EHP.
We will continue to promote further activities to conserve energy and prevent global warming through means that include the adoption of renewable energy-based power and reducing use of fossil fuels.

*1 Emissions coefficients for FY 2022 CO₂ emissions have been revised.

Use of renewable energy

In 2002, we installed 60 kW solar panels on the roof of the new Head Office building, which generate approximately 60,000 kWh per year (reducing CO₂ emissions by approximately 25 t-CO₂.) In 2004 we installed 50 kW solar panels on the roof of the Tateyama Factory. Following installation of additional units in 2007 and 2011, the solar panels at the Tateyama Factory now generate approximately 200,000 kWh per year (reducing CO₂ emissions by approximately 100 t-CO₂.) We also have installed internal power generation display monitors so that employees can check the amount of power generated at any time.
