Basic approach

The Glasgow Climate Pact was adopted at the 26th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP26) in 2021, with the aim of addressing the global issue of climate change. The Pact incorporates a commitment to strive to keep the rise in average global temperatures within 1.5°C, which would have a less severe impact than the earlier target of 2°C, by utilizing the latest scientific know-how, and it thus set a de facto goal for the world to work toward. The Pact confirmed that the next 10 years will be vitally important for realizing this, and that it is important to reduce overall global CO2 emissions by 45% by 2030 compared to 2010, and to cut emissions to net zero by 2050.

Toyobo group recognizes climate change as a very significant social issue that will have a critical impact on our business. We support the “Paris Agreement*” and "Glasgow Climate Pact" and aim to achieve carbon neutrality by the fiscal year 2051, consistent with the global 1.5°C target.

We also believe that it is important to collaborate with our customers, business partners, industries, local communities, the national government, and society as a whole in order to resolve climate change issues. Our group engages in discussions and dialogue with various stakeholders and works collaboratively to realize the net zero emissions and the goals of the Paris Agreements.

  • The Paris Agreement is a global framework adopted in COP21 in 2015 to reduce greenhouse gas emissions after 2020. For the first time in history, it is a fair agreement involving all countries and including the goal of keeping temperature rise below 2 degrees Celsius, and preferably 1.5 degrees Celsius.


President & Representative Director, CEO & Co-COO has the highest responsibility for climate change-related issues. The Board of Directors receives regular reports on climate change policies and significant matters discussed by the Sustainability Committee and provides supervision and guidance. The Sustainability Committee, chaired by the President & Representative Director, CEO & Co-COO, handles company-wide issues and risks, including climate change issues. In fiscal 2023, the Sustainability Committee met four times, and in response, the Board of Directors was reported five times, including regular reports and extraordinary reports. Following a resolution at the Board of Directors, we announced Sustainable Vision2030 in May 2022, and in April 2023, we officially joined the GX League, which was established by the government of Japan.


With regard to Scope 1 and 2*1 greenhouse gas (GHG) emissions associated with our business activities, we have set ourselves the target of realizing net zero emissions by fiscal 2051. In response to the growing momentum toward the realization of a decarbonized society, the Board of Directors passed a resolution to raise our intermediate-term target for fiscal 2031 to a target of reducing emissions by at least 46% compared to fiscal 2014 in May 2022.

In order to contribute toward realizing the decarbonized society, we are proceeding with efforts to reduce GHG emissions from the entire value chain deriving from activities that are related to our own business, while also working to expand the contribution that we make toward reducing GHG emissions through our products and services.

Approved by SBTi

In December 2022, the Toyobo group's targets of reducing GHG emissions by fiscal 2031 have been validated by the Science Based Targets (SBT*2) initiative.

Science Based Targets

The targets approved by SBTi are as follows.

Category Target Progress (Results in FY2023)
Scope1, 2 27.0% reduction in GHG emissions by FY2031 over FY2021 0.9% reduction from FY2021 level
Scope3*3 12.5% reduction in GHG emissions by FY2031 over FY2021 107.2% increase from FY2021 level

The target for Scope 1 and 2 corresponds to a reduction of GHG emissions by at least 46% by fiscal 2031 compared with fiscal 2014.

Scope1: Direct emissions from owned or controlled sources
Scope2: Indirect emissions from the use of purchased electricity, heat, and steam
A target to reduce greenhouse gas emissions in line with what is considered to be a state-of-the-art climate-science requirement to meet the Paris Agreement targets
Scope 3: Indirect GHG emissions other than Scope 1 and 2. The SBT validation is concerned with emissions from purchased goods and services and use of sold products.


Scope 1 and 2

The three site (Tsuruga, Iwakuni and Inuyama) account for approximately 70% of GHG emissions from our business activities (Scope1 2).

As regards the results in fiscal 2023, total Scope 1 and 2 GHG emissions came to 894 thousand tonnes CO2, 26.4% reduction from FY2014. While sales increased by 6.4%, GHG emissions remained at roughly the same level as in fiscal 2022 because we were implementing energy-saving activities and measures to enhance production efficiency.

The highest rank in“Business Operator Classification Evaluation System”

The “Business Operator Classification Evaluation System” is an initiative led by the Ministry of Economy in Japan. It divides all business operators, which submit regular reports under the Act on Rationalizing Energy Use, into four stages: S (energy saving is excellent), A (general), B (stagnation), and C (requires attention).

Under the system, four companies, including TOYOBO CO., LTD, TOYOSHINA FILM CO., LTD., TOYO CLOTH CO., LTD., and JAPAN EXLAN COMPANY, LIMITED achieved energy-saving targets through the introduction of energy-saving equipment and received S-class evaluations.

:For four years in a row since FY2020

As regards the results in fiscal 2023, total Scope 3 GHG emissions came to 5,290 thousand tonnes CO2, an increase of approximately 55% compared to the previous year. The main reason for the rise is a leap in the category 1 and 11 emissions. The category 1 emissions increased compared to fiscal 2022 due to the impact of soaring raw material cost and raw fuel prices. The increment in category 11 was mainly caused by a big leap in emissions from VOC treatment equipment which TOYOBO group provided worldwide. Sales of the equipment for Lithium-Ion Battery (LIB) separator plants were strong due to increased demand for LIB because of the global shift to EV. Accordingly, the emission of the category 11 was increased.

Category GHG emission Thousand tonnes-CO2
1. Purchased goods and services 2,055
2. Capital goods 55
3. Fuel- and energy-related activities (not included in Scope 1 or Scope 2) 113

Formulating roadmap for Carbon Neutrality

We have formulated a decarbonization strategy with a roadmap for Scope 1 and 2 emissions reduction aimed at realizing carbon neutrality. Based on the strategy, we have raised our intermediate-term target for fiscal 2031 to a target of reducing emissions by at least 46% compared to fiscal 2014, and we are proceeding with emissions reduction activities. As we expand our business toward fiscal 2031, our production volume will increase, and GHG emissions may increase in the future under a business-as-usual (BAU*) scenario. With the roadmap, we are targeting reductions in Scope 1 and 2 in fiscal 2031 by at least 46% compared to fiscal 2014 through energy optimization measures that involve energy conservation (including increased production efficiency), fuel conversion(away from coal), and adoption of renewable energy.

Key elements Contribution
Fuel conversion Approximately 40%
The others
・energy conservation (including increased production efficiency)
・Introduction of renewable energy
Approximately 60%

Roadmap for Carbon Neutrality

Energy efficiency and conservation

TOYOBO CO., LTD. has set a shared goal of improving energy-efficiency* by 1.0% or more annually. In fiscal 2023, TOYOBO CO., LTD. achieved the target through various energy-saving efforts. Specifically, this was due to the addition of waste heat recovery systems at in-house power plants and production lines, and the introduction of energy-saving equipment. Besides, the three sites (Tsuruga, Iwakuni, and Inuyama), which emit particularly large amounts of GHG in TOYOBO group, have set even higher targets and are actively working to reduce their use of energy.

In addition, TOYOBO group hold monthly meetings of the Energy Use Efficiency Committee. The committee consists of members from our main business sites and plants. They monitor the energy conservation activities of individual site and provides training on energy conservation (sharing knowhow, etc.). Additionally, each committee member conducts simple audits (“Energy-saving patrols”) at each factory site as appropriate to maintain and improve the level of activity.

  • Energy consumption per sales and production volume in accordance with Japan's act on rationalizing energy use

Fuel conversion (away from coal)

We are also implementing a transition toward low-carbon energy use, by switching to fuels with lower carbon contents for our in-house electricity generating equipment and installing additional gas co-generation system* equipment. We will begin by renewing our in-house thermal power generation plant at the Iwakuni Production Center, converting the fuel from coal to liquefied natural gas and RPF.*2 Major reductions in GHG emissions, approximately 80 thousand tonnes CO2, are expected from the operation, scheduled for fiscal 2024. We also added a gas co-generation system at Inuyama Plant and started operation in August 2023. It has improved the energy-efficiency of Inuyama Plant as a whole. We are carrying out GHG reduction measures including fuel conversion at other business sites as well.

  • Gas co-generation systems are systems that use natural gas to generate electricity, with the waste heat being harnessed to produce steam and hot water that are used in manufacturing processes, for supplying hot water, for air conditioning, etc.
  • An acronym for “Refuse-derived Paper & Plastics Densified Fuel,” solid fuel made mainly from used paper and waste plastic

Introduction of renewable energy

We are proceeding with the installation of photovoltaic power generation at each of our business sites, making use of roof spaces and unused land. In March 2023, Inuyama Plant began operating a photovoltaic power generation facility, which generated approximately 50MWh amounts of electricity in fiscal 2023. Utsunomiya Plant is also scheduled to begin operations of solar power generation facilities and other plants and offices are also considering the introduction of the system.

Solar power generation equipment installation at the Inuyama Plant


1,608 solar panels (power output approximately 500kW)
installed on the rooftop of Inuyama Plant

Inuyama Plant has proclaimed the slogan “Aiming for a Sustainable Plant” and is striving to improve energy efficiency, adopt energy-conserving facilities, and put renewable energy to use. In March 2023, the plant used a power purchase agreement (PPA*) arrangement to install a new solar power generation facility of approximately 500 kW. The factory also working to raise awareness of our employee by installing monitors in our offices that allow us to check power use and generation in real time. In the future, the plant is planning to implement other GHG reduction measures such as fuel conversion, and will continue to consider and introduce various initiatives to realizing to be a sustainable plant.

  • Businesses borrow roofs and idle land for facilities owned by enterprises, etc., and install power generation facilities free of charge. Electricity generated by enterprises, etc., is used in facilities, thereby reducing electricity rates and CO2 emissions.

Voice of the person in charge
This was the first time our company had tried a PPA, so we got the cooperation of a range of people, and the manufacturer of the solar power generation facilities, our company headquarters and the manufacturing division within the plant all worked together. It was a particular struggle connecting these facilities while giving consideration to the effect it would have on our existing electrical system. When it started generating electricity without a hitch, our hard work was paying off even more as it leads to reduced electric charges which continue to soar.

Initiatives related to the entire value chain

Reduction of Scope 3 emissions

TOYOBO group aims to reduce Scope3 and is implementing reduction measures mainly for Category 1*1 and Category 11*2 emissions, which account for a particularly large share of Toyobo group's Scope 3 emissions.

In Category 11, we have introduced new technologies and energy-saving technologies to VOC recovery equipment*3 to reduce the use of utilities (steam, electricity, etc.), thereby reducing GHG emissions and, at the same time, reducing the burden on environment.

Reduction of Scope 3 emissions

Emissions from activities (such as manufacturing) relating to purchased goods and services
Emissions from use of sold products
Equipment that removes VOC, Volatile Organic Compounds, by an adsorptive method, an absorptive method, or a chilling method, and recovers VOC as a liquid organic solvent. CO2 emission from VOC decomposition is zero. Moreover, the recovered organic solvent can be reused. VOC is a generic term for volatile organic compounds such as toluene, ethyl acetate, and dichloromethane. It causes atmospheric pollution / air pollution and is responsible for asthmatic and other health-related problems.

Expanding our avoided emissions

Most of the Toyobo group's products are materials or intermediate goods and many of these products contribute toward reducing GHG emissions. Typical examples of them include reverse-osmosis membranes (RO membranes) used in seawater desalination, and VOC treatment equipment, which controls emissions of VOC (volatile organic compounds) that are feared to have an adverse effect on atmospheric pollution / air pollution and the human body. We are making calculations to quantitatively understand GHG avoided emissions* of these products throughout their life cycles.

In fiscal 2023, in order to unify the internal calculation rules and expand the range of products subject to calculation, we developed our own guidelines that summarize methods for calculating GHG avoided emissions, etc. We have formulated the guidelines in accordance with the "Guidelines for Assessing the Contribution of Products to Avoided Greenhouse Gas Emissions" of the Institute of Life Cycle Assessment, Japan, and calculate avoided emissions according to the guidelines. We also refer to the “Guidelines for Quantifying GHG emission reductions of goods or services through Global Value Chain” issued by the Ministry of Economy, Trade and Industry in Japan.

We will expand our contribution to reducing GHG emissions by increasing sales of these products help to reduce GHG emissions.
For more information on avoided emissions calculation, please refer to the following sections.

  • GHG emissions that can be reduced by our customers' use of our products compared with conventional technologies.

Energy-saving initiatives in logistics

Our annual goal is a 0.5% year-on-year reduction in CO2 emissions per unit of transportation in relation to logistics.

In the Logistics Department, we launched the Green Logistics Promotion Project in 2006, and as well as working to improve quality and cost rationality, we are also continuously working on environmental conservation such as energy saving, resource saving, and prevention of global warming. Up until now, we have implemented a variety of measures in order to reduce the environmental impact of logistics. These measures include shortening transportation distances by using the nearest port to our production sites, and using efficient stacking and bulk transport of cargo in order to reduce the number of vehicles used. We are also actively promoting the usage of ship and rail transportation which have lower specific energy consumption than truck transportation, together with lower CO2 emissions.

We have been introducing a logistics system since 2019. Based on dispatch simulations, we worked to further improve loading efficiency by optimizing the allocation of vehicles and we were able to reduce CO2 emissions.

As a result of these efforts, we were able to reduce CO2 emissions per unit of transportation by approximately 5% in fiscal 2023 compared to the previous year.

Strengthening climate change measures

Structure to achieve carbon neutrality

In April 2021, Toyobo established the Carbon Neutral Strategies Council and the Carbon Neutral Strategies Cross-Functional Team (CN-CFT) to formulate and promote strategies to achieve carbon neutrality.

In order to make steady progress towards the realization of carbon neutrality, we also established working groups (WGs), with members from different units across the entire company, within the CN-CFT.
In fiscal 2023, the structure was reviewed, and a new Climate Change and Biodiversity Committee was established. We will promote companywide climate change responses with a view to internationally applicable sustainability standards.

WGs' main initiatives

  • Promotion of obtaining SBT certification
  • Formulation of the roadmap for Carbon Neutrality for Scope 1 and 2 emissions reduction (covering the period through to fiscal 2051)
  • Introduction of internal carbon pricing system

Introduction of internal carbon pricing system

On April 1, 2022, we introduced an internal carbon pricing (ICP) system in which the company use its own standards to set a theoretical price on each tonne of GHG emissions for reference in making capital investment. By using the ICP system as a yardstick for evaluating investment decisions, we will accelerate making investments not only in low or net-zero emission facilities and energy-saving technologies, but also in relevant equipment and facilities for research and development.

Outline of Toyobo's ICP system

Internal carbon pricing fee (tax) 10,000 yen for each tonnes of CO2
Targets of investment Capital investment in facilities with fluctuating CO2 emissions
How to use it Based on the internal carbon pricing fee, calculating CO2 fluctuation by the proposed facilities (including facilities for research and development) as costs. The calculations will be made in accordance with capital investment plans.

Disclosure based on TCFD

Recognizing the scale of the impact of climate change on our group and stakeholders, we have identified “a decarbonized and circular society“ as one of our materialities. In January 2020, we announced our support for the recommendations made by the Task Force on Climate-related Financial Disclosures (TCFD), and have been working on initiatives and disclosures that follow them.

In fiscal 2023, we expanded the scope of our scenario analysis to all our businesses. Based on the below 2℃ scenario (decarbonization scenario) and the 4°C scenario (warming progression scenario), we extracted the risks/opportunities of our group specializing in climate change. We have estimated the financial impact of risks and opportunities that we recognize as particularly important. For details, please refer to the integrated report.

Development of technologies that contribute to the realization of a decarbonized society



Osmotic power generation using high-salinity geothermal water, a source of renewable energy, has been receiving public attention. Toyobo has developed a forward osmosis (FO) membrane for the power plant core used in this method, and it has been used in osmotic power generation plants of Danish venture firm SaltPower.
In April 2023, it was installed at Nobians saltworks in Denmark and is now in operation.

Geothermal water osmosis power generation uses the high osmotic pressure of geothermal water with high salt concentrations pumped from underground. Compared with solar and wind power, the weather and time of day does not affect geothermal power generation. In addition, it does not emit harmful substances such as nitrogen oxides and sulfur oxides normally emitted during combustion.

Find more information about the other technologies here.

Collaboration with Stakeholders

Toyobo group believes that it is important to collaborate with our customers, business partners, industries, local communities, the national government, and society as a whole in order to resolve climate change issues. Our group engages in discussions and dialogue with various stakeholders and works collaboratively to realize the net zero emissions and the goals of the Paris Agreements.

Communication and Collaboration with business partners

Our group has established CSR Procurement Guidelines and asks our suppliers to cooperate in initiatives that support the development of a sustainable society throughout the supply chain. At the guidelines, we ask our suppliers to maintain and strengthen their environment activities, including initiatives aimed at solving the following climate change issues.

  • To strive to reduce greenhouse gas (CO2 and other gases) emissions, and mitigate climate change
  • To strive for effective use of resources and energy savings such as improving the efficiency of water and energy use

In addition, our procurement department conducts CSR procurement survey based on the guidelines to monitor the status of efforts to reduce GHG emissions and other initiatives. As a result of the survey, we ask suppliers to make improvements if they have any problems. For the latest survey results and countermeasures (corrective measures), please refer to the following sections.
