Carbon Neutrality Initiatives

We began working for carbon neutrality at Group business sites from an early stage, and have actively introduced solar power generating systems through onsite and off-site PPA.

In the future, we aim to further increase our percentage of off-grid power consumption by introducing storage batteries, and will prepare for the risk of high renewable energy power prices.

Active introduction of renewable energy

  • At the end of fiscal 2023, we achieved 100% introduction of renewable energy at 150 business sites where the Company contracts directly with power suppliers.

Results from renewable energy generation and off-grid energy consumption following introduction of off-site solar power generating systems (including off-site PPA)

  • For the solar power generating systems that we have been installing since fiscal 2012, installation was completed at 73 business sites where such installation is possible at the end of 2023.

      Amount of renewable energy generated: 14,465 MWh

      (including FIT)

Off-grid renewable energy consumption results following introduction of off-site solar power generating systems (PPA)

  • Introduction of off-site PPA in cooperation with Daigas Energy Co., Ltd. in November 2023

      Off-grid renewable energy consumption (expected): 2,129 MWh

  • Introduction of off-site PPA in cooperation with The Kansai Electric Power Co., Inc. in April 2024

      Off-grid renewable energy consumption (expected): 2,156 MWh

Off-grid Solar Power Consumption (MWh per Year) and GHG Emissions Reduction (t-CO2 per Year)

Installation of EV charging systems

  • Installed at a total of 82 stores by the end of fiscal 2023 Installation at 20 stores in fiscal 2024 (total installed: 102 stores)

 

Notes:

  1. Charging stands (details) Rapid charging: 3 stores, normal charging: 99 stores
  2. Rapid charging will be installed as soon as preparation of the necessary infrastructure is completed.

Introduction of storage batteries

  • Introduction of lithium-ion batteries linked with solar power, serving also as a BCP measure Introduced at 32 business sites as of the end of fiscal 2023.

 

Note:

  1. kW internal power conditioner type (Can sustain continuous       power usage of approx. 900 W for 12 hours.)

Introduction of BEMS

  • We are introducing demand control devices, and using automatic air conditioner control to reduce energy consumption and perform energy management. Introduced at 70 business sites (as of March 2024)

Acquisition of ZEB* (net zero energy building) certification

  • At present, we are acquiring ZEB certification for new stores that are at the planning stage. We are also studying whether acquisition of Nearly ZEB certification is possible at existing stores.

 

ZEB                 

Reduction to 0% with energy generation + energy savings

Nearly ZEB       

Reduction to 25% or less with energy generation + energy savings

ZEB Ready       

Reduction to 50% or less with energy savings

* ZEB: Buildings that utilize advanced architectural designs to reduce energy burdens, actively utilize natural energy, and introduce high-efficiency equipment to achieve large energy savings while maintaining the quality of the interior environment. Renewable energy is then added to increase energy independence as much as possible and reduce the annual primary energy consumption budget to zero.
