Climate Change
Asahi Kasei Group's Carbon Neutrality Policy
In accordance with its Group Mission, the Asahi Kasei Group is committed to contributing to life and living for people around the world. The Asahi Kasei Group has long been aware that climate change is a global issue that will have a significant impact on both the natural environment and society, and we see it as our mission to use the chemistry expertise we have cultivated since our founding to deal with this issue leveraging our combined strength.
In May 2021, the Asahi Kasei Group adopted a policy for carbon neutrality as described below.
Greenhouse gas (GHG) emissions targets for the Asahi Kasei Group*
- 2050
- Carbon neutral
- 2035
- Emissions reduction of 40% or more (from fiscal 2013)
- 2030
- Emissions reduction of 30% or more (from fiscal 2013)
- *Scope 1 (direct GHG emissions) and Scope 2 (indirect emissions use of electricity, heat, and steam supplied by other companies), absolute quantity
Initiative Policy
In addition to reducing GHG emissions from our own business activities, we believe that it is also important to help to reduce GHG emissions in society1 through our diverse array of technologies and businesses to deal with climate change. The materiality also set forth our commitment to "Decarbonization," and in April 2021, we launched the Green Solution Project. We are studying the creation of new businesses to help society become carbon neutral.
In April 2022, we launched a Carbon Neutrality Project2 to share and discuss scenario analysis and consolidate efforts to achieve our 2030 GHG emissions reduction targets and carbon neutrality by 2050.
Regarding "Care for Earth," we are committed to addressing climate change issues group-wide, both in terms of (1) reducing the amount of our own GHG emissions and (2) contribution to reducing the amount of GHG emissions in society through our businesses and technologies.

Reducing GHG Emissions
Concrete measures to reduce GHG emissions and their projected impacts
We are targeting a reduction in GHG emissions by at least 30% by 2030 as compared to fiscal 2013, and by at least 40% by 2035 as compared to fiscal 2013, with a goal of becoming carbon neutral by 2050. Measures will be advanced as described below.
In the first stage, by 2030 we aim to reduce our GHG emissions by approximately 300 thousand tons by adopting low-carbon methods for in-house power generation, by 100 to 200 thousand tons through the purchase of non-fossil fuel power, and by 100 to 200 thousand tons by curtailing emissions from our manufacturing processes. We will also promote GHG emissions reductions through transformation of our business portfolio, etc.
In the second stage through 2050, we will work toward greening both electricity and steam and the promotion of process innovation through practical application of technologies developed by Asahi Kasei, such as alkaline water electrolysis and CO2 separation and recovery. In addition, we will promote further transformation of our business portfolio, etc., and move forward with reductions toward attainment of our objectives.
- GHG emissions
Scope 1 and 2 GHG emissions
All production sites of Asahi Kasei Corp. and its consolidated subsidiaries under management control are subject to calculation of Scope 1 and Scope 2 GHG emissions of the Asahi Kasei Group, and GHG emissions from generation of electricity and steam sold outside the Asahi Kasei Group are included.
In fiscal 2023, our Scope 1 GHG emissions were 2.38 million tons of CO2-eq, and Scope 2 GHG emissions were 0.79 million tons of CO2-eq
, bringing the total of Scope 1 and 2 to 3.17 million tons of CO2-eq
This is a reduction in GHG emissions of approximately 38% compared to the 5.11 million tons of CO2-e released in the baseline year of 2013.

Efforts to Reduce CO2 Emissions
Renewable energy
Asahi Kasei Group has jurisdiction over 9 hydroelectric power plants in the Nobeoka/Hyuga region, which provide approximately 2% of the Group’s (Japan and overseas) electricity use. Generation of the equivalent amount of purchasing electricity would result in approximately 20 thousand tons* of CO2 emissions annually.
We also have a biomass power generation facility.
- * Using Japan's Ministry of Economy, Trade and Industry and Ministry of the Environment, Order No. 3 of 438 g CO2/kWh.
- Sources of electricity usage, FY2023 (global)
The table below shows the amount of renewable energy purchased and generated.1
Type of energy | Unit | FY2023 |
---|---|---|
Hydroelectric power generation | MWh | 56,701![]() |
Solar power generation | MWh | 256![]() |
Biomass-based2 generation | MWh | 55,550![]() |
Purchased non-fossil certificates3 | MWh | 161,114![]() |
Biomass-based2 steam | GJ | 317,192![]() |
- 1Hydroelectric power generation with no environmental value under the FIT system is excluded from the tally.
- 2The calculation is made by multiplying the amount of electricity and steam generated by the input ratio of biomass fuel in the co-combustion power generation of biomass and coal.
- 3Purchased non-fossil certificates include purchases for the Asahi Kasei Group.

Using Renewable Electricity in the Homes Business
As part of its efforts to address climate change, Asahi Kasei Homes joined the RE Initiative in 2019, aiming to achieve sustainable urban living through both a decarbonized society and resilience, and it became the first Japanese home builder to successfully achieve this.
Asahi Kasei Homes has progressed with its target to procure 100% of the electricity consumed for its business activities from renewable energy sources, successfully achieving RE100 in fiscal 2023, well ahead of the 2038 target set at the time of our participation.
Domestic energy saving in logistics
The Asahi Kasei Group promotes environmentally friendly railway shipment.
Product shipments for our operations in Japan amounted to some 0.9 billion ton-kilometers in fiscal 2023―an 10% decrease from fiscal 2022―generating approximately 72 thousand tons of CO2 emissions―a 6% decrease. In cooperation with the transport firms contracted for shipment, a wide range of measures are employed to reduce energy consumption and alleviate the environmental effects of physical distribution. We also actively participate in initiatives as a shipper, such as the “eco-transportation system” executed by local governments.
We have received Eco-Rail Mark certification in recognition of our preferential shipment of products by rail, an ecological mode of transport which results in lower CO2 emissions for a given weight and distance than many other means of transportation.
Domestic promotion of low emission vehicles
The Asahi Kasei Group is phasing in low-pollution vehicles for use in marketing and within plant grounds. In fiscal 2023, some 93% of company-owned vehicles were low-pollution vehicles.
