Continuous Improvement of Responsible Care Activities

Mitigation of Climate Change


Due to consumption of large amounts of fossil fuels such as oil and coal since the Industrial Revolution, greenhouse gas (GHG) emissions, including carbon dioxide emissions, are increasing and global warming is progressing. With the progression of climate change due to global warming, there is concern that various adverse effects on people's lives and the ecosystem will increase, such as increases in natural disasters including heavy rains and floods, reduction of food and water resources, and occurrences periods with intense heat and outbreaks of infectious diseases due to heat waves.

The Paris Agreement, which went into effect in 2016, aims to reduce the rise in average temperature well below 2°C (2°C target) as a long-term international goal in order to slow the progress of climate change and shift to a decarbonized society. In addition, it is stated that further efforts will be made to suppress the rise in average temperature up to 1.5°C. We support the Paris Agreement, position "mitigation of climate change" as one of the materiality factors, we have set a mid-term target (Scope1 + 2) of "reducing GHG emissions by at least 30% from FY2018 level by FY2027" aiming for achievement of carbon neutrality in 2050.

We also support the Japanese government's efforts to curb global warming, and comply with “Act on Promotion of Global Warming Countermeasures” and "Act on the Rational Use of Energy". In addition, we announced our support for recommendations of Task Force on Climate-related Financial Disclosures (TCFD).

In accordance with our Responsible Care Basic Policy, our Group will actively work to reduce greenhouse gases emissions in business activities and contribute to the mitigation of climate change through the provision of eco-friendly products and services.

Reduction of GHG Emissions (scope 1 + 2)

We set GHG emissions (Scope1 + 2) reduction target of “reducing by at least 30% from FY2018 level by FY2027” aiming for achievement of carbon neutrality in 2050.

As for GHG emissions, in accordance with the "Act on Promotion of Global Warming Countermeasures", we collect data on the emissions of carbon dioxide (CO2) and other GHG from all of our business establishments, including our plants, laboratories, and head office and submit this data to the national government. In addition, in order to examine the appropriateness of the calculation method, we have undergone a third-party verification since FY2018.

In FY2022, while dinitrogen monoxide (N2O) emissions increased owing to nitric acid plant trouble, etc., emissions decreased due to the suspension of melamine production and conversion of boiler fuel at the Onoda Plant, resulting in a decrease from FY2021.

Going forward, aiming to achieve FY2027 target, we will continue to consider various initiatives such as energy saving by upgrading to energy-efficient equipment and updating aging facilities, etc., emission reduction of nitrous oxide from nitric acid plants, fuel conversion, and CO2 fixation.

Understanding GHG Emissions through the Supply Chain (Scope 3)

We have calculated indirect GHG emissions (Scope 3) through the supply chain from raw material purchase to customer use and disposal. In addition, in order to examine the appropriateness of the calculation method, we have undergone a third-party verification, and in FY2022, category 6 and 11were verified.

Scope 3 of FY2022 was calculated and found to be accounted for 67% by purchased products and services (Category 1). Compared to FY2021, Category 1 increased due to the increasing demand caused by the global economic recovery from the impact of the COVID-19.

We have participated in the Ministry of the Environment Green Value Chain Platform, and the status of Scope 3 calculation is also disclosed at

Initiatives to Reduce Energy Consumption (Production, research and office)

In accordance with the "Act on the Rational Use of Energy", we collect data on the amount of energy consumed at all of our business establishments and submit this data to the national government, along with data on our energy consumption rate. Our energy consumption (crude oil equivalent) in FY2022 decreased by 16% compared to that of previous fiscal year.

Initiatives to Reduce Energy Consumption (Logistics)

As a cargo owner, we work together with Nissan Butsuryu Co., Ltd., a group company which handles our logistics operations, to promote the rational use of energy for transportation. In FY2022, the amount of energy consumption in crude oil equivalent decreased from the previous fiscal year, and the energy consumption rate was improved.
We have received the Eco Rail Mark certification in 2018, and we will continue striving to improve our energy consumption rate through measures such as promoting modal shifts, replacing vehicles with energy-saving and practicing eco-driving.

TOPICS:Introduction of Solar-power Generation System in Biological Research Laboratories

In October 2020, in response to Saitama Prefecture Global Warming Strategy Promoting Ordinance, the Biological Research Laboratories introduced self-consumed solar-power generation system as an initiative to reduce GHG emissions. Solar panels are installed on the roofs of the research buildings, which is expected to reduce greenhouse gas emissions by approximately 70 tons-CO2 per year. We will continue to promote our efforts to reduce GHG emissions.
