Decarbonization in business activities

70% reduction in GHG emissions by 2030

We are stepping up to the challenges of energy savings, electrification and renewable energy in pursuit of reductions to GHG emissions in our business activities.

Reductions to GHG emissions in our business activities(Scopes 1 and 2)

Energy savings

Fiscal 2030 targets

Fiscal 2030 target: Double energy efficiency (compared to fiscal 2015 levels)

In the area of energy savings, as a general rule we will build our own new facilities in ZEB* (Net-Zero Energy Building), and in existing facilities we will continue to invest in energy conservation and update facilities in a planned manner. In existing facilities, we will continue to invest in energy conservation equivalent to 15% of energy costs over more than 10 years and systematically replace equipment. We aim to achieve the goal of doubling the energy efficiency of our business operations by 2030, which is the goal set forth in EP100.

* ZEB: Refers to Zero Energy Buildings that are designed to achieve net zero primary energy consumption yearly, by improving the energy-saving performance with insulation and energy-efficient equipment, and creating energy through solar power generation or similar means.


Fiscal 2030 targets

CEV conversion rate 100%

In the area of electrification, we are promoting the use of clean energy vehicles (CEVs), aiming to achieve a 100% adoption rate for company vehicles and a 30% adoption rate for personal cars of employees, who are allowed to use those vehicles for work purposes, by 2030.

Renewable energy

Fiscal 2025 targets

Renewable energy rate 100%

In the area of renewable energy, we aim to achieve a 100% utilization rate of renewable energy by leveraging the value of such energy derived from the renewable energy power plants developed and operated by the Group.

In fiscal 2020, the amount of electricity generated by the Group exceeded that used, and as of March 31, 2023, the Group operated renewable energy power plants with a total capacity of 612 MW (including in-house consumption), which is 1.57 times as large as the Group’s power consumption. We will continue to expand the development and operation of renewable energy power output, mainly solar power generation, aiming to operate 2,500 MW as of 2030.

Contributing to the expansion of power generation by creating our own renewable energy

Achieving RE100

The Group was a step ahead of other companies in commencing development of renewable energy power generation, and in 2000 led off with the installation of large-scale wind and solar power generation systems in its own facilities, while also undertaking development at the hotels, factories and other locations it owns and operates. Since the establishment of the FIT program (*1) in 2012, we have been working to expand the amount of renewable energy generated, and from fiscal 2020 we have been promoting the switch to electricity generated by our own renewable energy power plants for use at our own facilities.

We created a scheme for self-sufficiency for renewable energy-generated electricity as a measure to realize RE100 by utilizing the non-fossil fuel energy certificates (*2) system that started in fiscal 2020. In fiscal 2022, we made the electricity purchased by the Company in Japan 100% renewable energy from our own power plants on a non-consolidated basis. For fiscal 2023, we aim to use 100% renewable energy for all electricity purchased by the entire Group, as well as overseas power purchases. Beyond that, we aim to achieve RE100, which includes our in-house power generation.

  • *1 FIT program: A feed-in tariff program for renewable energy
  • *2 Non-fossil fuel energy certificates: The “environmental value” (e.g., no greenhouse gas emissions) of power derived from renewable energy sources, etc., is separated out and made tradable. With tracking, it is possible to identify the power plant from which the environmental value originated.
