TOK Co., Ltd. (Headquarters: Itabashi-ku, Tokyo, President: Keisuke Yoshikawa) has achieved a 49.2% reduction in CO2 emissions as of FY2025 under its "TCN47 (TOK CARBON NEUTRAL 47)" initiative, which targeted a 47% reduction compared to FY2019 levels. This realizes the initial FY2030 goal five years ahead of schedule.
This outcome is the result of the introduction of renewable energy and the accumulation of continuous, site-led energy-saving improvements.
Following this success, TOK is launching a new project, "TCN55+," aiming to reduce CO2 emissions by 55% by FY2030.
## Background of TCN47
In recent years, demands for corporate decarbonization in response to climate change have rapidly increased, making the reduction of CO2 emissions a critical management issue in the manufacturing sector as well.
Particularly, companies are required to set mid-to-long-term reduction targets based on SBT (Science Based Targets) and manage emissions across the entire supply chain (Scopes 1, 2, and 3).
- Scope 1: Direct greenhouse gas emissions by the company (e.g., fuel use)
- Scope 2: Indirect emissions from the consumption of purchased electricity, heat, etc.
- Scope 3: Emissions throughout the supply chain, including raw material procurement, logistics, product use, and disposal
It should be noted that the reduction targets for the "TCN47" initiative cover Scope 1 and Scope 2.
Against this backdrop, TOK set the "TCN47" goal of reducing CO2 emissions by 47% by FY2030, using FY2019 as the base year, and has promoted efforts company-wide.
## Results and Success Factors of TCN47
The biggest factor behind this achievement lies in the initiatives at our Yamanashi plant.
This plant achieved a CO2 reduction of approximately 134 tons annually, accounting for about 90% of the total reduction volume.
Major measures implemented include the following:
- Introduction of solar power generation systems
- Switching to LED lighting
- Updating to high-efficiency air conditioning equipment
This outcome is the result of the introduction of renewable energy and the accumulation of continuous, site-led energy-saving improvements.
Following this success, TOK is launching a new project, "TCN55+," aiming to reduce CO2 emissions by 55% by FY2030.
