Environmental Initiatives Policy
Since its foundation, the Chiyoda Group has strived to embody its corporate philosophy of “Energy and Environment in Harmony” and has been promoted business activities.
In the transition period to a low-carbon society that the international community is aiming for, starting with the Paris Agreement, we recognize that climate change countermeasures through our business are important management issues. To address this global issue, we will create new innovations with digital innovation technology using the engineering technology we have cultivated, and play a role in a carbon cycle society.
We established Greenhouse Gas(GHG) Emissions Reduction in order to take on the mission of realizing a sustainable society that balances social and economic values.
In order to continue to promote a carbon-recycling society through our business, we will continue to strengthen our efforts for renewable energy, and in addition to taking on the challenge of providing energy through the hydrogen supply chain and establishing a decentralized / complex utility business. We will realization of decarburization and recycling with technological development .
We agreed with the recommendations of the Task Force on Climate-related Financial Information Disclosure (TCFD) , we will actively disclose information in line with the TCFD recommendations.
TCFD Initiatives
In 2019, the Company declared its support for the Task Force on Climate-related Financial Disclosures (TCFD) recommendations. We participated in the Ministry of the Environment’s “Project to Analyze Scenarios of Climate Risks and Opportunities in Accordance with TCFD” and conducted scenario analysis on climate change. As we proceed, we will enhance our analysis for use in our management strategies while disclosing information in line with TCFD recommendations.
Please refer to the following for our scenario analysis.

Impact Calculations
A countermeasure policy, based on impact calculations implemented in our business strategies (global environment, digital transformation, redefining Chiyoda’s engineering value)
●4ºC scenario; No promotion of carbon taxes or carbon cycles, and continued dependence on fossil fuels
●2ºC scenario; Promotion of low carbon and carbon cycles, greater demand for green energy facilities, and accelerated implementation of hydrogen and CCU

Case study of project
Construction of the Largest Mega Solar Power Plant in Tokai Region
●Contributing to Reductions in CO2 Emissions
We completed construction of Pacifico Energy’s Toyota Mega Solar Power Plant in Toyota City, Aichi Prefecture, in March 2020, nearly two and a half years after breaking ground in October 2017. With an annual projected power output of 74 million kWh and the ability to generate electricity for approximately 21,000 households, this mega solar power plant is the largest of its kind in the Tokai region spanning Gifu, Aichi, and Mie prefectures. Through the use of cleaner energy in the form of solar power, we will contribute to reducing CO2 emissions by approximately 40,000 tons* per year.
●Preserving the Landscape of Local Communities
In constructing the Toyota Mega Solar Power Plant by the Yahagi River, we worked with local companies to preserve the pristine landscape of the river’s watershed while ensuring the safety of the local community by installing a resilient disaster-prevention facility. As the land consisted of slopes of 20° or greater, we utilized 3D design to ensure that there were no shadows or gaps when installing the solar panels. The project came to fruition through our technological expertise combined with the united efforts of customers, local affiliates, and government agencies. The Company will continue to work with customers on renewable energy projects in the future to support the goal of a decarbonized society.

●Stable Supply of Renewable Energy
The use of renewable energy generated through solar and wind power is increasing in line with the growing drive toward a decarbonized society. Storage batteries, connected to power systems controlling power generation, energy transmission and distribution, store excess energy for discharge when required and resolve the issue of unfavorable weather conditions and the natural environment adversely affecting the stability of energy supply.
Continuing with this initiative, we are constructing the North Toyotomi Transformer Station Storage Battery System in Toyotomi, Teshio District, Hokkaido, the largest and most advanced energy storage battery system in the world, supplying energy through wind power.
●Providing Safety and Security to Local Communities
For this project, we actively participated in festivals and events and worked together with local communities to ensure the safety and security of the area. For example, following the Hokkaido Eastern Iburi earthquake in September 2018, which resulted in the entire region of Hokkaido Prefecture losing power for several days, the site manager acknowledged an urgent request from local dairy farmers and used the generator from the project to provide power, which enabled them to continue working without sustaining too much damage. As we proceed, we will continue to devote our attention to safety and the environment to support the realization of a sustainable society, while striving to meet customer and community requirements.

Chiyoda and euglena - Aiming for a carbon-neutral society together
In October 2018, Chiyoda Corporation (Chiyoda) completed construction of a bio-diesel fuel production demonstration plant for euglena Co., Ltd. (euglena) in the Keihin coastal area of Tsurumi-ku, Yokohama, and the facility has supplied bio-diesel fuel for buses etc since April 2020. Since its completion, Chiyoda, euglena and Chevron Lummus Global Applied Research Associates (process licensor) have pursued a bio-jet fuel that meets international standards. In March 2021, we successfully produced a bio-jet fuel conforming to ASTM D7566 Annex 6 standards * and are aiming for its use in aviation later this year.
Raw materials for the bio-jet fuel consist of oil and fat used in cooking oil, derived from the microalga euglena gracilis (Japanese name: euglena), which greatly reduces jet aircraft CO2 emissions.
Chiyoda will continue contributing to the realization of a carbon-neutral society by applying our engineering expertise accumulated from industrial plant construction over many years.
