As expressed in our Group Vision that includes "harmony with the natural environment," the Asahi Kasei Group places high priority on environmental initiatives. The Group Policy regarding global environmental measures is shown below.

The Asahi Kasei Group's Global Environmental Policy

1. Building a low-carbon society

  • (1) Taking into account Japan's Plan for Global Warming Countermeasures and Nippon Keidanren's "Proposal on Japan's long-term growth strategy under the Paris Agreement," the Asahi Kasei Group aims for greenhouse gas emissions related to its business activities to meet reduction targets by 2030.
  • (2) The Asahi Kasei Group will promote energy conservation across the full range of our business activities with the aim of preventing global warming and conserving limited resources.
  • (3) The Asahi Kasei Group will develop a plan to reduce CO2 (Scope 3) emissions from its supply chain.
  • (4) The Asahi Kasei Group will help create a low-carbon society incorporating our proprietary technologies, contributing to the reduction of global greenhouse gas emissions by providing products, technologies, and services to the global market.

2. Preserving water resources

The Asahi Kasei Group will contribute to preserving global water resources through our water purification membrane module business, water recycling service business, and the sale of water quality monitoring equipment and wastewater treatment products. It will measure the quantity of its water intake while striving to maintain and improve the efficiency of its water usage.

3. Recycling

The Asahi Kasei Group will promote the reduction of environmental impacts and the efficient utilization of resources and energy throughout the entire life cycle in its business activities in order to contribute to a circular economy. Specifically, it will promote the 3Rs of reduction, reuse, and recycling, and increase the usage of resources and energy with lower environmental impacts as well as renewable resources and energy.

4. Achieving harmony with nature

The Asahi Kasei Group will give due consideration to the conservation of natural capital and biodiversity, and promote the reduction of environmental impacts of its business activities. We will also monitor and carefully manage our use of land and biological resources.

5. Overseas plants

The Asahi Kasei Group will create monitoring items that enable environmental management practices equivalent to those at its plants in Japan.

6. Supply chain

The Asahi Kasei Group will proactively collaborate with members of its supply chain to undertake the abovementioned activities.

Management framework

The Group's global environmental measures are part of our Responsible Care program, and we have established a management system based on ISO 14001 requirements.
See below for the Responsible Care (RC) promotion framework.

By 2030, emissions reduction of 30% or more (from fiscal 2013)
Clean power generation
Maintain use of biomass fuel at 60% or more by energy content in mixed combustion at the biomass power plant in Nobeoka

2. Energy management target

Management target
Improve unit energy consumption by an annual average of at least 1% over a 5-year period

3. Water resource preservation activity target

Our target is shown in the response to question W8.1a of the CDP Water Security Questionnaire 2021 posted on the Water Resource Preservation page.
