CO₂ Reduction

Breakdown of CO₂ emissions

CO₂ accounts for most of the greenhouse gases released by TAMRON. As regards the sources of CO₂ emissions (excluding distribution and logistics), electricity usage accounts for 98%, followed by heavy oil at 1%. Given this mix, our energy saving activities focus on electricity.

Change in CO₂ emissions

In 2022, Tamron set the target of reducing CO₂ emissions by 6% compared with 2015 levels. In addition to the in-house consumption of renewable energy through solar power generation at the Foshan Plant in China and other sights, since May 2022 non-fossil fuel certificates have been issued for roughly 30% of the electricity used at the head office, achieving net-zero CO₂ emissions for the portion of electricity self-generated and covered by the certificates. Tamron Optical (Foshan) Co., Ltd. in China has also purchased I-REC applying to part of its electricity usage, achieving net-zero CO₂ emissions for the portion covered by the purchases. In part due to those effects, overall we were able to achieve our targets with a reduction of 15.1%, exceeding the target reduction.

Ascertaining CO₂ emissions in the supply chain (Scope3)

In order to realize a low-carbon society, not only activities within TAMRON but also efforts throughout the supply chain including upstream and downstream are important. To promote our efforts, we have grasped indirect greenhouse gases (Scope 3) related to business activities in the supply chain.

Ascertaining CO₂ Emissions in the Supply Chain (FY2022)

Initiatives to Reduce CO₂ emissions

In 2017, Tamron Optical (Foshan) in China began installing solar power generation systems. At the end of 2020 additional generating systems were installed, and in 2022 CO₂ emissions were reduced by around 580 tons, which corresponds to roughly 2.5% of the emissions produced by the Foshan Plant. In addition, since May 2022 Tamron has subscribed to the Green Basic Plan^*1 that involves the issuance of non-fossil fuel certificates covering roughly 30% of the electricity used at the head office. Tamron Optical (Foshan) Co., Ltd. also purchased I-REC^*2 certificates covering part of its electricity usage in 2022. Combined, approximately 4,300 tons of CO₂ were reduced to effectively zero. In 2023, we have set the target of reducing CO₂ emissions by at least 9% compared with 2015 levels, and will make every effort to achieve this target CO₂ Reduction Effect in 2022.

*1 Green Basic Plan: A RE100-compatible effective renewable energy option that combines FIT non-fossil fuel certificates (with tracking) for the average electric power of all power sources provided by TEPCO Energy Partner, Inc. and non-FIT non-fossil fuel certifications (with information about power source attributes) specific to renewable energies.
*2  I-REC: Renewable energy-based electricity certificates certified and issued according to the rulebooks and electronic tracking systems based on them provided by the Netherlands-based non-profit organization I-REC Standard.

Tamron is participating in the “Electrical and Electronics Industry Low Carbon Society Action Plan,” an initiative to combat global warming.
