Since its establishment in 1897, Meidensha has produced a range of technologies, products, and services and contributed to the development of a sustainable society in its role as a manufacturing company. In particular, we are deeply involved with decarbonization and reduction of carbon through power generation systems that utilize renewable energy sources such as solar, wind, and small to medium hydroelectric, as well as energy solution services such as smart grids. Through these environmentally conscious products, we aim to contribute to the achievement of a sustainable society and we are working to reduce greenhouse gas emissions from business activities.
Under the direction of the President, who is the Chief Executive Officer, the Executive Officer (Environment) oversees the environmental management of the entire Meiden Group, while the Environmental Manager in Charge of EMS promotes maintenance and improvement of the environmental management system.
As the highest decision-making body with regard to environmental activities, the Meiden Group Environmental Committee, which is chaired by the Executive Officer (Environment), identifies issues including risks posed by climate change and deliberates concerning environmental targets, action plans, and emergency response, etc., as well as determining environmental management direction. As part of its role, the Environmental Committee refers important matters to the Executive Committee and the Board of Directors, etc., to initiate activities based on executive-level decision-making.
Direct emissions from in-house use of fuel, etc.
Indirect emissions from power or heat purchased from an outside source
Scope 1: Direct Emissions
Combustion of fuel (town gas and oil, etc.) and release of greenhouse gasses (SF6 and CFCs, etc.)
Scope 2: Indirect Emissions
Combustion of fossil fuel to generate electricity (electricity company) that is consumed by the company
* Renewable energy produces zero emissions
* Japanese emissions: The amounts of fuel oil and fuel gas are calculated referring to the "List of Calculation Methods and Emission Factors in the Calculation, Reporting and Publication System" published by the Ministry of the Environment. The amount of electric power is calculated referring to the "Emission Factor List by Electricity Power Company" published by the Ministry of the Environment.
* Overseas emissions: The amounts of fuel oil and fuel gas are calculated referring to the emission coefficient by country published by the GHG protocol. The amount of electric power is calculated referring to the average coefficient by country in 2010-2012 published by the International Energy Agency (IEA).
* Energy consumptions per unit are emissions (t-CO2) divided by net sales (million yen).
* Energy consumptions per unit are energy consumption (crude oil equivalent, kL) divided by net sales.
The Meiden Group is conducting strategic capital investment in order to reduce greenhouse gas emissions from energy consumption, such as by replacing lighting and air conditioning equipment with highly efficient models. Furthermore, we are working to improve operation of equipment by enabling visualization of power consumption and strictly managing power consumption, particularly at night and on holidays.
In fiscal 2019, our domestic CO2 emissions decreased due to pursuing energy-efficiency measures such as work efficiency and improving the operation of air conditioners and compressors, and the initiation of new electricity procurement using non-fossil fuel certificates. Furthermore, CO2 emissions per sales unit improved over fiscal 2017.
Going forward, we will further streamline energy usage through capital investment and operation.
Since November 2019, Meidensha has procured electricity from substantially renewable energy sources for the R&D Center and Osaki Kaikan Hall in combination with FIT*1 and non-fossil fuel certificates*2, which carry tracking information for the subsidiary, M WINDS Co., Ltd.’s Choshi Shiosai Wind Farm. Through non-fossil fuel certificates containing tracking data, we are able to link electricity that is consumed by the R&D Center and Osaki Kaikan hall to the environmental value of energy produced by the Choshi Shiosai Wind Farm, demonstrating that we produce net zero CO2 emissions. In this way, electricity consumption by Meidensha’s R&D Center and Osaki Kaikan hall produces net zero emissions.
Furthermore, using non-fossil fuel certificates with tracking information makes it possible to conform with the international initiatives RE100, which has the goal of obtaining 100% of the electricity required for business activities from renewable energy sources. This expand our options to effectively utilize existing wind farms.
As demand for electricity from renewable energy sources is rapidly increasing, with the aim of decarbonization, Meidensha will continue to work to reduce our environmental impact and provide products and services that contribute to a sustainable society.
*1 Feed-in tariff (FIT) system: A system to require electricity companies to purchase electricity generated from renewable energy sources (solar, wind, hydro, geothermal, biomass) for a certain period of time. The system was launched in July 2012 in order to promote the use of renewable energy.
*2 Non-fossil fuel certificate: A certificate issued by the Ministry of Economy, Trade and Industry that certifies the environmental value of electricity that does not create CO2 emissions, such as electricity from renewable energy sources. Trading commenced through Japan Electric Power Exchange in May 2018, and a demonstration experiment that included tracking information (information that clearly states the type and location of energy source) in certificates commenced in March 2019.
Kofu Meidensha Electric Mfg. Co., Ltd. acquired the highest five-star rating for BELS for its newly constructed EV factory on its premises.
BELS is a third-party rating system that indicates the energy efficiency features of buildings. It uses a five-star rating system to objectively rate energy efficiency based on primary energy consumption.
The new EV factory acquired the highest rating due to its 250-kW photovoltaic equipment and 100-kW battery, walls and window glass with exceptional insulation properties, optimized HVAC and lighting, etc.
The Meiden Group’s emissions of greenhouse gasses other than CO2 include SF6 gas, which is used for lightning arresters and circuit breakers, etc., and CFCs, which are used as refrigerants in air conditioners.
With regard to SF6 gas, which contributes greatly to the greenhouse effect, we are working to reduce emissions and conducting technical investigations and trials of substitute gasses. Furthermore, in order to reduce CFC emissions, we are promoting stricter management and replacement of air conditioners.
The transport division is conducting product transport efficiency reforms such as mixed loads and modal shift, as well as initiatives to reduce CO2 emissions from transport. There are many issues relating to product transport, including diversification of forms of delivery, but going forward, we will work to reduce CO2 emissions by promoting efficient transportation.
Meidensha is working to calculate greenhouse gas emissions, including indirect emissions in the upstream and downstream supply chain in addition to those produced in the course of its business activities.
Meidensha is facing the issue of producing a large proportion of its emissions from “use of sold products” (scope 3, category 11) and “purchased goods and services” (scope 3, category 1). We are promoting environmental measures throughout the entire supply chain, including reducing downstream greenhouse emissions through environmentally considerate product design and reducing upstream impact through green procurement.
