Awareness of risks and opportunities in climate change, risk management

【Climate change adaptation and risk management for the stable supply of products】

The Tokai Carbon Group is a B-to-B materials manufacturer targeting companies as customers, and the materials and components we manufacture are the starting point of the everyday production activities of our customers. To fulfill our responsibility as a company within the supply chain of our customers, we believe it is important to continue the stable supply of our top-quality products.
Our Group is aware of the risk that climate change poses to the stable supply of our products. We have verified the impact of typhoons and flooding brought about by climate change in the short term and medium term, and are taking steps such as implementing flooding countermeasures at our high-priority offices and, in our main businesses, spreading the risk among multiple domestic bases. We have incorporated the cost of climate change risk countermeasures in our facilities budget planning, and will implement further measures in future based on our plans. We predict risk due to climate change, and incorporate this into our Business Continuity Plan (BCP) in our aim to alleviate the risk.
At Tokai Carbon, the Board of Directors supervises climate change risk, and the board member in charge of risk reports important matters to the Board of Directors as necessary. As with other important risks, climate change risk is managed within the company’s overall management process.

Membership in external organizations

【Japan Chemical Industry Association (JCIA)】

We participate in the activities of the Association as a member of JCIA,. The purpose of JCIA is to promote the development of chemical industry through research on various issues such as technology, labor, environment, and safety in the chemical industry. In the environmental field, JCIA agreed to "Low Carbon Society Execution Plan" compiled by Japan Business Federation. The chemical industry as a whole has announced a target of reducing greenhouse gas emissions (1.5 million tons of CO2 emissions compared to FISCAL 2005 in FISCAL 2020). As a member of the JCIA, we are working to reduce CO2 emissions and conserve energy in order to achieve this goal.

【Japan Carbon Association】

Japan Carbon Association is an organization of carbon products manufacturers to further develop the carbon products and the industries. President of Tokai Carbon has been appointed as a chairman of this association. In recent years, we have been working together with our peers to reduce CO2 emissions, as it is essential to consider climate change mitigation in conducting corporate activities.

  • *1 Data collection period: From April to March each year.
  • *2 The data collection period for Categories 1-3 and 5-15 under Scope 3, for which data collection was commenced in 2019, is from January to December. References for the calculation of Scope 3 include “Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (ver. 2.3)” (Ministry of the Environment and Ministry of Economy, Trade and Industry (METI)) and “Database on Emissions Intensities for Calculating Greenhouse Gas Emissions, etc. through a Supply Chain (Ver. 2.6)” (Ministry of the Environment and METI), as well “Greenhouse Gas Emission Factors by Power Operators” released by the Ministry of the Environment.
  • *3 Calculated by multiplying the total amount of main raw materials purchased by the applicable emission intensity.
  • *4 Calculated by multiplying the purchasing price of capital goods by the applicable emission intensity.
  • *5 Calculated by multiplying the volume of waste disposal by type and the volume of recycling by the applicable emission intensity.
  • *6 Calculated by multiplying the number of employees by the number of operating days and the applicable emission intensity.
  • *7 The scope of reporting is the Graphite Electrodes Segment. The figure was calculated by multiplying the energy consumption of products and the sales volume by the applicable emission intensity and adding CO2 emission from the products in use.
  • *8 The scope of reporting is the Graphite Electrodes Segment.
