Dealing with climate change

ISK Group Aiming for Carbon Neutrality by 2050

With climate change becoming a major worldwide issue, the ISK Group has identified dealing with climate change and reducing environmental impacts as priority issues (materiality) and aims to become carbon neutral by 2050.

Disclosure based on TCFD Recommendations

ISK has announced its support for the Task Force on Climate-Related Financial Disclosures (TCFD)* recommendations.

*TCFD (Task Force on Climate-Related Financial Disclosures): The TCFD recommends that companies evaluate the financial impact of the risks and opportunities posed by climate change on their business management and provide disclosure on the four areas of governance, strategy, risk management, and metrics and targets.

Governance

Concrete efforts in response to climate change are carried out by our Climate Change Team. This team operates under the Sustainability Promotion Committee, which reports directly to the President.
The team comprises people from factory management, manufacturing divisions, administrative department, and ISK affiliates.
The efforts and measures the team comes up with are deliberated on at Sustainability Promotion Committee meetings held at least twice a year, and those approved are consulted on and passed by the Board of Directors.
The progress of activities by the Sustainability Promotion Committee, including the Climate Change Team, is reported every three months to the Board of Directors, which supervises these activities.

Strategy

Chosen Climate Change Scenarios

Referencing climate change scenarios published by the IEA (International Energy Agency) and IPCC (Intergovernmental Panel on Climate Change), we selected scenarios of a rise of 1.5–2°C and 4.0°C. Recognizing that climate change’s impact on business becomes more evident in the medium- and long-term, we analyzed the impact of climate change until 2050, as the time horizon.
Analysis of the scenario for fiscal 2023, we extends to the organic chemicals business. All businesses of the ISK Group (inorganic chemicals/organic chemicals) were analyzed under the scenarios.

4℃ scenario: Maximum emissions scenario with no climate policy and development dependent on fossil fuels
(IEA STEPS, SSP2-4.5, RCP8.5)

1.5–2℃ scenario: Scenario with sustainable development and climate policy to keep temperature rise under 2℃ compared to pre-industrial levels but to also aim to keep it to 1.5℃ or less
(IEA NZE 2050, IEA SDS, SSP1-2.6, RCP2.6)

Scenario Analysis Results

The ISK Group used external information to analyze the main climate change risks and opportunities in our business, and gathered future forecast data related to each risk and opportunity.
Based on this, we considered the risks and opportunities that arise from the transition to the carbon neutral society under each of the 1.5–2°C and 4°C scenario. We then analyzed the major risks and opportunities that could impact our business up until 2050.
As a result, for the 1.5–2°C scenario, we identified risks such as greatly increased operating costs due to the imposition of a carbon tax on CO₂ emissions.
Therefore, recognizing the importance of reducing CO₂ emissions across the entire ISK Group, we will proceed with various planned measures towards achieving carbon neutrality by 2050.

Risk Management

One of the eight priority issues (materiality) that the ISK Group has identified is “dealing with climate change and reducing environmental impacts.”
In recognition of the urgency of climate change, the ISK Group has established the Climate Change Team under the Sustainability Promotion Committee. This team identified climate change risks, the results of which are assessed and controlled by the Sustainability Promotion Committee. When necessary, matters are reported to the Corporate Risk Management Committee.

Indexes and Targets

For Scope 1 and 2 GHG (greenhouse gas) emissions, in addition to those disclosed last year at ISK Group companies in Japan, we also calculated those at overseas group companies so as to understand emissions for the entire ISK Group. Scope 3 (supply chain) emissions were also calculated in order to grasp the overall state of GHG emissions from ISK Group business activities. To reduce Scope 2 GHG emissions, the Yokkaichi Plant has begun including renewable energy from biomass in the electricity that it purchases.

Drawing a Road Map to Carbon Neutrality

The Yokkaichi Plant, our flagship production base, has been using a coal-fired cogeneration system to achieve optimal energy costs in manufacturing. But because of the occurrence of extreme weather events due to climate change, reducing CO₂ emissions has become a priority issue. We have therefore drawn a road map to carbon neutrality for the ISK Group in Japan through multistage CO₂ reductions, with the Yokkaichi Plant at the center of this effort.
We aim to systematically reduce CO₂ emissions (Scope 1 and Scope 2) 30% by 2030 compared to fiscal 2019. This will be achieved, for example, by replacing coal for boilers with low-carbon fuels, rebuilding manufacturing systems, thoroughly saving energy, using renewable energy, capturing CO₂ in various processes, and improving facilities. Towards achieving carbon neutrality in 2050, in addition to the measures mentioned above, we will aim to dramatically reduce emissions through innovative technologies, and explore the development and implementation of decarbonization technologies such as CCUS (carbon capture,utilization, and storage).
