Environmental Vision FY2020 Results (Major Initiatives) Evaluation
Targets of Eco Action Plan 2030

Zero-Carbon Society

  1. 1)The Scope 1 and 2 emissions have decreased 7.6% from the base year (fiscal 2019) mainly due to a significant decline in sales of beverage containers and other packages amid the COVID-19 pandemic. We will continue with our energy-saving efforts, including the replacement of production equipment.
  2. 2)The emissions from supply chain (Scope 3) have declined 6.0% due to lower production as well. There have also been effects of various resource-saving initiatives such as developing more lightweight containers.


  1. 1)Reduce CO2 emissions from our operations (Scope 1 & 2)
    by 35% (compared to FY2019)
  1. 2)Reduce CO2 emissions from the supply chain (Scope 3)
    by 20% (compared to FY2019)

Zero-Waste Society

  1. 1)The consumption of exhaustible resources has decreased 18% from the base year (fiscal 2013). This is largely due to lower production, while we have been working on reducing product weight and improving yield rates (lowering defective rates) to achieve the target.
  2. 2)We seek to reduce the consumption of fossil resources by using recycled plastic from used bottles for creating new PET bottles and plant-based resin for other plastic containers.


  1. 1)Reduce the use of exhaustible resources(1)
    by 30% (compared to FY2013)
  1. 2)Reduce the use of fossil resources(2)for plastic products
    by 40% (compared to FY2013)
    • 15% reduction by decreasing product weight and switching materials
      (compared to FY2013)
    • Increasing the ratio of recycled and plant-based plastics
      by 30% (compared to FY2013)
  1. 3)All packaging to be recyclable or reusable

Society Coexisting with Nature

  1. 1)The release and transfer amount of chemicals subject to the PRTR Law has declined 18% from the base year (fiscal 2013). Although there was a deviation from the target for several years because of production process control for certain products, we have achieved the target with various improvement efforts, such as excluding toluene from printing ink (the annual 9% reduction in fiscal 2019 significantly improved the progress).
  2. 2)Water withdrawal has increased 3%. While the use of water has decreased at domestic facilities, the expansion of overseas operations has pushed up the total amount compared to the base year.
  3. 3)We manage plastic pellets with the guidelines we have set for all group companies to prevent plastic pellet from escaping from our facilities. Meanwhile, we have participated in the Clean Ocean Material Alliance, which consists of a wide range of business operators across the supply chain.


  1. 1)Reduce environmental risk and environmental pollutant
    • 15% cut in the release and transfer amount of chemical substances
      under the Pollutant Release and Transfer Register Law (PRTR Law)
      by FY2022 (compared to FY2013)
  1. 2)Promote biodiversity conservation
    • 30% cut in water consumption in operations (compared to FY2013)
  1. 3)Promote communication with external parties
    • Action to address marine plastic pollution (prevention of litter)
      and the disclosure of relevant information
  • Note:
  • 1.An exhaustible resource is a natural resource that is not replenished by natural processes as fast as humans consume it.
  • 2.Fossil resources include crude oil and natural gas.

Toward a Zero-Carbon Society

As part of our efforts to address climate change, we have initiated several measures to achieve carbon neutrality. In fiscal 2021, we started a multifaceted review of sourcing and use of energy at the Osaki Forest Building (Shinagawa, Tokyo), where Toyo Seikan Group Holdings and other major group companies are headquartered, and at the Corporate R&D (Yokohama, Kanagawa), the basic research lab of the Group.

CO2 Emissions from Operations (Scope 1 & 2)

In fiscal 2020, total carbon emissions from the Group’s facilities in Japan and abroad decreased 8% from the previous year to 1,381 thousand tons.

The emissions from the domestic facilities declined by 111 thousand tons from the year earlier as a result of lower production, replacement of air compressors, periodic repair of melting furnaces and other energy-saving activities, while those from overseas facilities decreased by 2 thousand tons year on year.

We continue to engage in cutting carbon footprint in fiscal 2021 through energy-saving efforts, including replacing equipment, streamlining production lines and improving production efficiency.

Changes in CO2 Emissions from Operations(1)(2)(3)

Changes in CO2 Emissions from Business Activities
  • Note:
  • 1.In May 2021, we raised our reduction targets.
  • 2.The 35% reduction compared to FY2019 is equivalent to a 45% reduction compared to FY2013 (the previous 30% reduction target was compared to FY2013).
  • 3.The figures for the previous years have been retroactively revised due to a change in the electricity grid emissions factor and the addition and correction of data for certain facilities.

Greenhouse Gas Emissions from Supply Chain (Scope 3)

The Toyo Seikan Group calculates the amount of greenhouse gas emissions from the upstream and downstream of the supply chain (Scope 3) as well as the amount of emissions from its operations (Scope 1: direct emissions from fuel combustion, and Scope 2: indirect emissions from electricity consumption). Under our environmental vision Eco Action Plan 2030, we aim to reduce the Scope 3 emissions 20% by fiscal 2030 compared to fiscal 2019.

In fiscal 2020, the Scope 3 emissions associated with our domestic operations accounted for approximately 80% of the total emissions from the Group’s domestic operations and supply chain. Of the total Scope 3, the emissions from purchased products (Category 1) accounted for approximately 73%, followed by disposal of sold products (Category 12) and capital goods (Category 2). This indicates that reducing emissions related to purchased products (e.g. material procurement) is becoming more and more important. We will continue to work together with material suppliers on reducing product weights and using more recycled and plant-based materials.

More Use of Renewable Energy

As part of our efforts to reduce greenhouse gas emissions from operations, we have been introducing solar power systems to our facilities. Two domestic facilities, Tokan Kogyo's Komaki Plant and Toyo Kohan's Kudamatsu Plant, began to operate the system in December 2020 and in February 2021, respectively. Outside Japan, Toyo Filling International in Thailand launched the system in August 2020. We will step up the introduction of renewable energy as a key measure to address global warming going forward.

Promoting Modal Shift - Recognized as Eco Ship Mark Certified Business

We have committed ourselves to more efficient transportation with less environmental impact by making active efforts to build an efficient truck transportation system and promote modal shift.

In April 2021, Toyo Seikan and Toyo Mebius have been certified as Eco Ship Mark Businesses for 2020 in the Eco Ship Modal Shift Project, led by the government and shipping companies in Japan. The project gives certifications to shippers and logistics companies that are actively engaged in reducing emissions by shifting to ocean transport, which is highly efficient and environmentally friendly. In 2020, the two group companies were recognized for changing the transportation method from truck to ocean for part of their product shipments (approximately 400 truckloads annually) between the Kansai and Kyushu areas in Japan.

We as a whole group will continue to advance our commitment to reducing environmental impact for the creation of a sustainable world.

Achieving a Zero-Waste Society

Our group companies produce packaging containers and materials by processing raw materials from exhaustible resources, such as metal and petroleum. We therefore believe we have a great responsibility for an efficient use of resources through reducing material input and waste and recycling materials. Under the Eco Action Plan 2030, we are taking measures to achieve the 30 % reduction target for the use of exhaustible resources toward a zerowaste society.

In addition to our ongoing efforts to develop more lightweight containers, we are also working on expanding the use of recycled materials. Using more recycled metals in our cans and more recycled or plant-derived resins in our plastic containers will help us achieve the targets of the action plan and eventually help solve social issues. These activities should not only lead to an effective use of resources but also reduce emissions from the material production process, and they are also important from the perspective of combating climate change.

Certification of Eco-friendly Products

The Toyo Seikan Group has been working on developing, manufacturing and selling low environmental impact products, considering their entire lifecycle. We have certified several products of the Group as Eco-friendly Products based on our group-wide standards for evaluation in the stages of raw material procurement, production, transportation, consumption and disposal/recycling. As of the end of September 2022, a total of 70 items have been certified as Eco-friendly Products.

Click here for the list of our Eco-friendly Products (available only in Japanese).

Going forward, we expect that the development and commercialization of eco-conscious products will contribute to achieving the targets of Eco Action Plan 2030. We will strive to develop products keeping in mind the reduction of waste and recycling at their end of life so that they will be widely accepted in the market.

Achieving a Society Coexisting with Nature

Risk Management of Production Facilities

Harmful substances and waste liquid that flow out of plants have a long-lasting adverse impact on the surrounding environment. While group companies have been individually implementing risk management with their environment management systems, we are now further enhancing our risk management framework. We identify equipment and facilities that carry high risks of environmental accidents based on the degrees of deterioration in facilities and the characteristics of substances handled by individual plants. The management of piping and storage tanks are given special attention since a leakage from such equipment would have a material impact.In fiscal 2021, we established environmental risk management guidelines common to all group companies to launch a group-wide risk management system.

Addressing Marine Plastic Pollution

Engagement through Clean Ocean Material Alliance

In January 2019, the Clean Ocean Material Alliance (CLOMA) was established with a wide range of business operators participating to address marine plastic pollution, an emerging global challenge. The CLOMA is aimed at promoting a new 3R (reduce, reuse, recycle) initiative toward more sustainable use of plastic products and the development and introduction of alternative materials through public-private collaboration. Toyo Seikan Group Holdings has joined the alliance as a managing partner since the preparation phase and has been working as a key member of a subcommittee of CLOMA to share information and enhance the network with partners from across industries.

In 2020, CLOMA formulated an action plan to advance plastic recycling as a countermeasure against marine plastic pollution. Another four companies of our group: Toyo Seikan, Tokan Kogyo, Nippon Closures, and Mebius Packaging, have also joined the alliance to implement measures to achieve the action plan. In working groups that are relevant to their business domains, the companies are tackling new challenges to reduce additional marine plastic litter to zero by 2050.

Strong Commitment to Plastic Pellet Loss Prevention

Plastic pellets with a size of several millimeters, which are used to make plastic products, could become marine plastic litter if they escape from the plant site. We have been taking measures to prevent the particles dropped on the ground from flowing out the site, including placing metal net on the storm drain. In 2019, to further ensure appropriate pellet management aimed at zero pellet loss, we formulated the Group’s Guidelines for Preventing Plastic Pellet Loss. The relevant group companies have started implementing the guidelines under their respective environment management systems by identifying potential leakage points, taking preventive measures, and conducting daily management processes and auditing.

Cleanup Efforts with Litter Picking App “PIRIKA“

For communicating our cleanup efforts, we have used a litter collection app “PIRIKA” to post articles about our activities on the web since fiscal 2019. In fiscal 2020, a total of 457 people across the Group joined the program and picked up 3,909 liters of waste. In addition to the activities in the surrounding areas of our facilities, we also joined programs led by local communities and organizations. Ryukyu Seikan, a group company in Okinawa, joined the “Beach Cleanup” organized by the Tourism Association in Nago City, and was certified as a community contributor. Meanwhile, Toyo Seikan Group Holdings participated in the “Arakawa River Clean Aid” in Tokyo for the first time.

We will continue with our commitment to cleanup activities more related to the communities in which we operate, in cooperation with regional partners.

FY2020 Topics

Investing in Plastic Recycling Venture, R Plus Japan

Toyo Seikan Group Holdings has set up a joint venture, R Plus Japan Ltd., together with 12 companies from the plastics value chain, including Suntory MONOZUKURI Expert Ltd., TOYOBO CO., LTD. and Rengo Co., Ltd., for plastic recycling business. The new company started up in June 2020, aiming to create and commercialize an eco-friendly, efficient plastic recycling system that is under development based on the technology of Anellotech Inc., a US biochemical venture. R-Plus Japan is working toward practical application of the system by 2027 through the cross-industry cooperation.

The company mainly serves three functions in this project: fundraising, supporting development activities, and driving commercialization. It has increased the number of investing partners to 29 (as of July 2021) to secure funds, while working on development support activities, including analyzing materials and sending the samples to Anellotech as well as sharing information on competing technologies. The Toyo Seikan Group is supporting the project by joining the taskforce for technology to conduct technical research and other activities.

Combining the technologies we have developed across the Group over many years, we will fulfill our responsibility as a member of the value chain to contribute to solutions to plastic issues, working toward a sustainable future.

Participation in Ellen MacArthur Foundation

The Toyo Seikan Group has joined the Ellen MacArthur Foundation (EMF) in the United Kingdom as the fourth Japanese company and as the first packaging manufacturer, aiming to gain knowledge about the circular economy and to explore opportunities to collaborate with other corporations. The EMF is a charity founded in 2010 with the aim of accelerating the global transition to a circular economy through partnerships with businesses, governments and research institutions.

Through workshops hosted by the EMF and joint projects with member companies, we will make proposals for various packaging solutions suited for different regions and countries by taking advantage of our strengths as a comprehensive packaging company, thereby contributing to the realization of a circular economy. We are currently working on a proposal for “aTULC Compact Line,” a can making system that requires less space for installation and has less impact on the environment.

Please refer to the details of aTULC and the aTULC Compact Line through the following link.

Toyo Seikan Receives Appreciation from Saitama Government for Zero Carbon Commitment

Toyo Seikan's Kuki Plant and Saitama Plant jointly received a letter of appreciation from the Saitama prefecture government for their contribution to "Zero Carbon Saitama," a carbon offsetting initiative in the prefecture.

Through its activities to upgrade equipment and improve production efficiency during the period from 2011 to 2014, Toyo Seikan has obtained carbon credits (net reduction in emissions) of approximately 159 thousand tons of CO2 equivalent, far exceeding the reduction target set in the initiative, and decided to donate these credits in response to the call of the local government. The company will continue with its efforts to be a corporation that helps create a sustainable society.
