Gunma Manufacturing Division

To contribute to global environment conservation, the Gunma Manufacturing Division that manufactures Subaru vehicles is actively engaged in efficient use of energy through carrying out efficient, step-by-step capacity increase.

Initiatives for Prevention of Global Warming

CO2 emissions in FY2017 was 298,674 tons-CO2.
We will continue efforts in energy conservation and contributions in preventing global warming.

Changes in CO2 Emissions

Note:
After FY2016, the transitional data for CO2 emissions is presented in the values calculated and reported based on the Act on Promotion of Global Warming Countermeasures.

Initiatives for Zero Landfill

The amount of waste material discharged in FY2017 was 105,856 tons.
The amount for landfill was 0 tons, continuing zero landfill from FY2002.
We will continue to improve recycling and reduce waste material discharge.

Changes in Waste Material Discharge and Landfill

Note:
Subaru definition of zero landfill
Total volume of landfill waste (amount directly sent to landfills + amount sent to landfills after intermediate processing) is less than 0.5% of the total waste volume (industrial waste + industrial waste subject to special control + general waste from business activities) excluding metals

Initiatives for Pollution Prevention

In order to maintain harmony with the local society and the lush natural environment, we promote initiatives such as managing exhaust gas and effluent and reducing environmental risk as well as activities for preventing occurrences of environmental accidents and pollution.
We will continue our efforts for a target of zero that includes exceeding standards.

Environment-related Measurements for FY2017

Voluntary standards for air, water quality, noise, vibrations, etc. are set and are managed to be 20% higher than the legal standards.

Water quality measurements

All measurement results were compliant with Water Pollution Prevention Law, Gunma prefectural regulations, and Ota-Oizumi pollution prevention agreements.

Saitama Manufacturing Division

Industrial Products Division had promoted creating an environmental management system (EMS), including the supply chain, and reducing environmentally hazardous substances.
Creating an EMS based on certification (ISO14001, Eco Action 21, etc.) from external organizations continues toward a 100% compliant system, with 133 suppliers, including new transaction partners, becoming certified.
Efforts had been made to perform various surveys and reduce environmentally hazardous substances in order to comply with various regulations such as EU directives.

Please note that going forward, Industrial Products Co., Ltd., our affiliate, will continue to promote these efforts.

Utsunomiya Manufacturing Division

We will strive to work toward environmental issues such as global warming prevention efforts, in order to fulfill our social responsibilities as corporate citizens developing/manufacturing aircrafts, etc.

Initiatives for Prevention of Global Warming

Again in FY2017, energy conservation activities were promoted by managing energy use at each work site, which led to reduction in total CO2 emissions.
Unnecessary energy use was reduced by implementing an energy conservation patrol at all factories and work sites.
For equipment/facility improvements, a switch to LED lighting and updating to energy saving air conditioners are still ongoing.
The CO2 total emissions base unit was a 6% reduction from FY2007 levels.
We will continue further efforts in energy conservation and contributions in preventing global warming.

Initiatives for Pollution Prevention

In order to maintain harmony with the local society and the lush natural environment, we promote initiatives such as managing exhaust gas and effluent and reducing environmental risk as well as activities for preventing occurrences of environmental accidents and pollution.
Ground operation of helicopters at the South Plant have been moved to the apron as far away as possible from the site boundaries in consideration of reducing noise to the neighboring houses.
We will make efforts to reach our voluntary standards and to keep environmental accidents and complaints on and off-site to zero.

Environment-related Measurements for FY2017

All measurement results were compliant with Water Pollution Prevention Law, Utsunomiya City sewer regulations that are applied to each area and Handa environmental protection agreements, and have cleared our voluntary standards that are 20% higher.

We have set our voluntary standards for all measurements (air, water quality, noise and vibrations) to be 20% higher than the legal standards.

Signing of the Environmental Protection Agreement with Handa City

We previously had a pollution prevention agreement focusing on conventional pollution prevention with Handa City. On February 22, 2011, based on a request by the city, we signed an environmental protection agreement that expanded our activities to focus further on the environment such as energy conservation and waste.
