Response to Climate Change

Basic approach

Recognizing climate change as an important issue, our group has been working from an early stage to reduce CO2 emissions at our domestic and overseas production sites, such as by launching the "CO2 Reduction Project" in fiscal 2010.

In addition, in order to "visualize" the environmental impact of a product over its entire life cycle, including procurement of raw materials, production, use, disposal, and recycling, we continue to conduct LCA (life cycle assessment) of our products and publish the results. At the same time, by providing products with low environmental impact, we are contributing to the reduction of CO 2 emissions from our customers' products themselves. We will continue to reduce the environmental impact of our entire supply chain by striving to reduce CO 2 emissions from our products.

We believe that efforts from a longer-term perspective are necessary in order to respond to the social situation where demands on companies are becoming more active, such as recent global trends in climate change response, carbon neutrality, and SDGs initiatives. In January 2022, we formulated the sustainability vision "ASV2050/2030" as medium- to long-term goals looking toward 2050. We will accelerate our efforts to achieve carbon neutrality in 2050.

CO 2 emissions reduction target in asv2050/2030

ASV2030 aims to reduce CO2 emissions (domestic) by 35% compared to FY2020 to 50,000t-CO2, and CO2 emissions (overseas) to 95,000t-CO2, a 35% reduction compared to FY2030 BAU. Masu. To achieve this, we will take various measures in three areas: "reducing energy consumption," "low-carbon energy use," and "low-carbon electricity use," with the aim of achieving further reductions.

Results in 2022

CO2 emissions

In fiscal 2022, the total amount produced by the group was 182,538 tons (down 8.9% compared to the previous year), which was a decrease compared to the previous year both in Japan and overseas. This is due to a decrease in production volume, changes in production items, and efforts to reduce CO 2 emissions.

Changes in CO 2 emissions and basic unit of sales
CO2 emissions

Scope of calculation: All domestic bases and major overseas production affiliates

  • For CO 2 emissions related to electricity (domestic), emissions coefficients for each electricity company published each year are used.
  • CO 2 emissions related to electricity (overseas) are calculated using country-specific emission factors listed in the IDEA database.

energy usage

In fiscal 2022, the total amount for the group was 85,221kL (5.0% decrease compared to the previous year), which was a decrease compared to the previous year both domestically and overseas. This is due to lower energy usage due to reduced production. On the other hand, the energy consumption rate (the amount of energy required to produce 1 ton of product) remained unchanged due to a decline in operating rates.

Scope of calculation: Domestic major manufacturing facilities/factories and domestic affiliated companies; overseas, major overseas production affiliated companies.

Compliance with TCFD

In November 2020, we endorsed the TCFD (Task Force on Climate-related Financial Disclosures). We will enhance and accelerate our environmental initiatives, including measures to address climate change, and promote information disclosure in line with TCFD recommendations.
