Climate change initiatives
Reducing greenhouse gases
The Group considers environmental problems such as climate change to be important issues for management to address. Based on this awareness, we defined practicing ESG management as one of the challenges in our 2030 Vision announced in May 2021, and set environmental, social, and governance KPIs respectively as well as specific targets in Medium-Term Management Plan (2021-2025), which we are working systematically and continuously to achieve.
We will actively engage in eco-friendly business practices, which include reducing greenhouse gas emissions, while also working actively to contribute toward solutions for climate-related social issues through businesses such as renewable energy.
Additionally, in December 2021 we declared our support for the recommendations of the TCFD (Task Force on Climate-related Financial Disclosures) and also joined the TCFD Consortium. The Group is making information disclosures according to the TCFD Framework.

Engaging in renewable energy-related business
The Group contributes to the spread of renewable energy by assisting with the installation of solar power plants, self-owned power lines for wind power generation, and through efforts such as designing, constructing, and performing maintenance on biomass boilers.
Photovoltaic plants
The Group provides EPC (engineering, procurement, and construction) services for solar power plants, and also proposes and supplies enterprise solar power generating facilities for internal use in companies.
Specific services include support for the introduction of large-scale solar power generation (mega-solar) utilizing the feed-in tariff scheme, and support for the rooftop or proximity installation of in-house solar power generating equipment for industrial facilities and other buildings with electric power supply needs. We offer comprehensive solutions that incorporate storage battery utilization and other elements.

Wind power generation
We provide integrated services for building self-owned power lines in both offshore and onshore wind power generation, and Engineering, Procurement and Construction (EPC) for transformer facilities. Specifically, for self-owned power lines we contribute to wind power generation business by using the Earth Shuttle Method to lay pipes that reach all the way to the sea floor while protecting the natural environment in the pipeline process, and employing hard-to-find specialist technicians called cable jointers who we develop and train on our own in line extension and connection processes.
Biomass boilers
We provide construction and maintenance services for various biomass boilers that play a part in recycling systems.
Specifically, we take materials such as woody biomass that have a high moisture content and have been traditionally regarded as waste products and enable their utilization as biomass resources. These resources are used to produce steam, supply heated water, perform drying, supply heated water for air conditioning, and to operate high-efficiency power generation systems.
