CO₂ Reduction through Initiatives at Operational Sites

Canon thoroughly tackled the reduction of CO₂ emission during operation. Through the group-wide actions including painstaking energy management and regular checks of equipment status and operating settings, we pursue the improvement of energy efficiency.

Greenhouse Gas Emissions at Operational Sites

Through the efforts of the Energy Cost Reduction Working Group, coupled with the rigorous streamlining of production processes and other actions by our operational sites to reduce energy use and adopt renewable energy, GHG emissions at operational sites were kept at 1,001 thousand t‑CO₂e. In 2026, we will push ahead with efforts to reduce CO₂ emissions, mainly by saving energy and utilizing renewable energy sources at our business locations.

Greater Energy Efficiency at Production Sites

Reducing Power Consumption in Production Using Factory Green Cost Management (GCM)

At Canon, we use “GCM” to refer to the management framework we have developed that targets parallel reductions in costs and CO₂ emissions, alongside decarbonization efforts based on the development of green technologies. Within this framework, we focus on "factory GCM" initiatives that aim to reduce the power used at the production stage. In factory GCM, a factory's energy data is automatically collected and plotted in graphs (visualization of electricity) through established systems, which has facilitated not only the instant identification of wasteful operations (analysis of reduction potential), but also the systematic accumulation of data across the entire company, thereby enabling the immediate discovery of appropriate reduction measures (expansion of reduction measures).

The factory GCM system is being gradually rolled out across Canon production sites, with installation completed in 2025 at six major sites in Japan that use large amounts of electricity.

This initiative has yielded more sophisticated energy management at production sites, with the rollout demonstrating concrete results.

For example, we used the system to discover wasteful operations involving certain production equipment, which resulted in a 10% reduction in power consumption. Canon aims to further improve energy efficiency across the Group by rolling out the system to overseas sites in 2026 as well as in Japan.

Comment from a Production Site with a Newly Introduced System

The rollout of a factory GCM system in our workplace has enabled us to visualize energy consumption and put an analysis method in place, fostering an environment where anyone can easily work on improving the energy consumption of our equipment. As a result of everyone working together on-site to take action to reduce consumption, we are moving forward quickly and effectively with improvements. Furthermore, this initiative has sparked awareness on the manufacturing frontlines about coming up with ideas and putting them in practice to improve not only energy consumption but the environment as a whole.

Through these efforts, we will build a corporate culture of realizing sustainable manufacturing.

Energy Cost Reduction Working Group

Canon created the Energy Cost Reduction Working Group in 2014 as a horizontally integrated organization to take Group-wide action on reducing energy consumption. The working group has promoted reduced energy consumption by undertaking a thorough-going analysis of the required operating environment for production equipment in the on-site manufacturing process and using its findings for instance to reduce equipment operating time, cut out excess use of pressurized air and cooling water, and adjust air conditioner settings. Measures that prove effective are adopted for horizontal rollout to Japan and overseas production sites. Moreover, staff members from our corporate headquarters in charge of this initiative perform a diagnosis of energy performance during visits to production sites all over the world. There, they check the operating status and settings of production equipment and then use their observations to make improvements to the operating efficiency of facilities and equipment and provide staff with relevant on-site training.

Since its launch, this initiative has resulted in Canon-wide energy savings of 277,066 kL (crude oil equivalent).
