With a view to helping realize sustainable, low-carbon societies, the Toray Group is pursuing initiatives for reducing greenhouse gas emissions. Toward this end, the Group worked to save energy by improving manufacturing processes and introducing cogeneration in accordance with its Fourth Medium-Term Environmental Plan, which was launched in fiscal 2011. The Group will be working to meet new targets for reductions in greenhouse gas emissions in fiscal 2016 and beyond.
Toray Energy Conservation Activities
Toray has set a goal of reducing its per-unit energy consumption by 2% annually. In fiscal 2015, Toray reduced energy consumption by 1.6% year-on-year and improved its per-unit energy consumption by 0.04% year-on-year, bringing it down now to 13.8% below the base year of fiscal 1990. The reduction was achieved due to productivity improvements combined with steady implementation of energy conservation initiatives at plants, as well as energy conservation diagnostics performed by the Company’s own energy efficiency specialists.

Promoting Energy Conservation Diagnostics

The Toray Group organizes energy conservation teams to help carry out energy conservation diagnostics at plants according to a plan. In fiscal 2015, these activities were conducted at four of Toray’s plants, along with six group company plants at in Japan and one outside Japan. The energy saved during the year was equivalent to about 25,400 tons of CO2.
Toray’s Efforts to Fight Global Warming
Under the Fourth Medium-Term Environmental Plan, which covered fiscal 2011–2015, Toray systematically worked to reduce greenhouse gas emissions, with the goal of maintaining greenhouse gas emissions at least 10% below the 1990 level. In fiscal 2015, Toray reduced its CO2 emissions by 32,000 tons year-on-year. Greenhouse gas emissions were down 1.4% year-on-year at 2.12 million tons, which was 17% below the 1990 level, continuing to meet the reduction target.
Moving forward, Toray will endeavor to meet its reduction targets despite the higher production volumes projected due to business growth.

Gas Cogeneration and Mixed Combustion of Biomass Fuel
Expanded biomass fuel facilities at Toray’s Tokai Plant
The Toray Group is systematically switching to natural gas and installing cogeneration systems to conserve energy. In fiscal 2015, Toray’s Mishima Plant began operation of a cogeneration system.
The Group is also focusing on the use of biomass fuel made from wood chips for power generation. Toray’s Tokai Plant is expanding the mixed combustion of wood chips for its private boiler power generation facility, to reduce CO2 emissions from boiler operations.
These measures are projected to reduce approximately 40,000 tons of CO2 emissions annually in fiscal 2016.
Greenhouse Gas Emissions (Toray Group in Japan)
Toray and its group companies in Japan worked to curb global warming with the goal of reducing emissions by 15% on a per-unit-of-sales basis by fiscal 2015 compared to the fiscal 1990 level.
Greenhouse gas emissions were down 0.4% in fiscal 2015 compared to the previous fiscal year. Greenhouse gas emissions per unit of sales improved by 0.3 points compared to the previous fiscal year and were 16% below the base year.

Greenhouse Gas Emissions (Toray Group)
Fiscal 2015 greenhouse gas emissions for the Toray Group worldwide were 5.5 million tons-CO2 equivalent, an increase of 5.2% compared to the previous year. All Toray Group manufacturing companies and plants will continue to work to achieve the Group’s goal of reducing the per-unit energy consumption rate by 2% each fiscal year.

Initiatives to Protect the Ozone Layer
Toray successfully ceased using chlorofluorocarbons (CFCs) in all manufacturing processes in 1994. The Company has also stopped purchasing CFCs for use in refrigeration equipment and will finish upgrading refrigeration equipment that uses CFCs by fiscal 2019.
