To achieve decarbonized societies, we strive to reduce CO2 emissions through energy conservation and cleaner power consumption. In addition, we at the Group pursue manufacturing practices that incorporate energy and resource conservation (what we call Eco Manufacturing).
We are reducing emissions steadily every year to achieve our targets, exercising energy conservation and using cleaner electricity from renewable energy sources.
In FY2021, we achieved a 50% reduction compared with FY2016 levels through energy-saving initiatives that include ongoing capital investment in energy-saving equipment and efforts to expand solar power generation facilities.
We aim to achieve 100% renewable electricity at sites in Japan by fiscal 2024. We intend to achieve this target by continuing to improve energy efficiency, while also utilizing renewable energy-derived J-Credit Scheme*1 and self-consignment*2 provided our own energy solutions business.
As part of our Eco Manufacturing initiative, we have improved facilities, invested in equipment, and installed optimized equipment at our operating sites. Several examples are shown below.
We introduced fan inverter controls and cooling water controls as energy-saving measures for HVAC equipment. We also reviewed systems controls, enacted measures against air leaks, and adjusted discharge pressure to optimize compressor operation. These efforts resulted in a 1,931MWh (1.2kt-CO2) reduction in power consumption compared with the previous year.
Based on the action plan through fiscal 2021, we pursued energy conversion (electrification), transformer upgrades, and HVAC system replacement at each operating site. As a result, we reduced power consumption by 4,566MWh (2.3kt-CO2) compared with the previous year.
Fourteen sites in Japan, China, Italy, and Indonesia use electricity generated in-house via solar power.
In FY2021, we continued to invest in renewable energy facilities at each site in accordance with our action plan. We made new installations at the Aso Plant (Kumamoto, Japan) and the Indonesia Plant. We also expanded facilities at the Yamaga Plant (Kumamoto, Japan) and the Shanghai Plant in China. In total, we estimate new renewable energy power generation of 1,225MWh for FY2021.
As a result, our annual power generation from in-house power generation is 2,564Mwh.
In the Kansai area of Japan, we continued procurement through centralized power purchasing that incorporates internal carbon pricing. Overseas, we began procuring electricity in Malaysia as an additional area after the Netherlands.
The amount of electricity purchased from these renewable energy sources totaled 49,280MWh.
