Climate-related Organizations to Which We Belong

In December 2020, デュエルビッツ ボーナスel announced that it supports the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).

TCFD

TCFD Consortium

As a member of the Global CCS Institute and the Carbon Recycling Fund Institute, we actively acquire the latest information on CCUS (Carbon dioxide Capture, Utilization and Storage) technology and work on technological development and research on CO2 separation, capture, recycling and sequestration for future practical use.

  • Global CCS Institute

The Global CCS Institute is an international think tank whose mission is to accelerate the deployment of carbon capture and storage (CCS), a vital technology to tackle climate change and deliver climate neutrality. The institute is headquartered in Melbourne, Australia, with offices in Tokyo, Washington DC, Brussels, Beijing and London.

  • Carbon Recycling Fund Institute

The Carbon Recycling Fund Institute aims to address the global warming issue and improve the energy access throughout the world. The institute promotes innovation in carbon recycling by public relations and sponsoring the research and development in the field.

In addition, each of the following industry groups to which the KOBELCO Group belongs has formulated a Commitment to a Low Carbon Society. We will contribute to the achievement of the targets set out in the Commitment to a Low Carbon Society of each industry group to which we belong by pursuing energy savings and CO2 reduction in production processes.

Industry groups Industry targets for reducing CO2 emissions from production processes in the Commitment to a Low Carbon Society
FY 2020 target FY 2030 target
The Japan Iron and Steel Federation Eco Process: Reduction*1 of over 3 million tons versus BAU*2 Eco Process: Reduction of 9 million tons versus BAU
Japan Aluminium Association Reduction of 1.0 GJ/t energy intensity per unit of rolled volume versus BAU in FY 2005 Reduction of 1.2 GJ/t energy intensity per unit of rolled volume versus BAU in FY 2005 (best effort target)
Japan Copper and Brass Association Reduction of 4% energy intensity versus BAU with production activity volume of 380,000 tons Reduction of 6% energy intensity versus BAU with production activity volume of 380,000 tons
The Japan Society of Industrial Machinery Manufacturers Average annual improvement of at least 1% energy consumption per unit (kL/¥100 million) Reduction of 10% in CO2 emissions versus FY 2013
Japan Construction Equipment Manufacturers Association Reduce the manufacturing energy consumption rate by 8% from the 5-year average of 2008 to 2012. Reduce the manufacturing energy consumption rate by 17% from the actual achievement of 2013.
  • *1 The Japan Iron and Steel Federation prioritizes 3 million tons of reduction arising from energy conservation and other voluntary actions by steelmakers. For waste plastics and other recycled materials, the emission reduction counts only a decrease resulting from the increase in the volume of these materials collected compared to FY2005.

    *2 BAU (Business As Usual): emissions of greenhouse gases, or emissions per unit, assuming no additional measures are taken

Relationship with Industry Associations

The President and CEO of デュエルビッツ ボーナスel has been appointed as vice chairman of the Japan Iron and Steel Federation, and デュエルビッツ ボーナスel is actively and deeply involved in the activities of the industry organizations to which it belongs.

デュエルビッツ ボーナスel’s officers and employees have been appointed to various committees of industry associations related to climate change. They are actively involved in industry association activities such as setting goals, following-up the results and summary, sharing information, and attending meetings organized by industry organizations to exchange opinions with government officials.

デュエルビッツ ボーナスel has taken the following steps to ensure consistency with the positions of industry associations. When business associations discuss matters related to public policy, relevant committees present draft proposals. As デュエルビッツ ボーナスel’s officers and employees are appointed as members of various committees related to climate change, they share the proceedings of these committees within the company to confirm whether they are in line with デュエルビッツ ボーナスel’s position and policy. If there are any inconsistencies, they make adjustments through the committees. We also constantly exchange information with industry groups on デュエルビッツ ボーナスel’s climate change strategies and targets in order to ensure consistency with their positions and targets. Through this process, we ensure デュエルビッツ ボーナスel’s climate change strategy is aligned with the efforts of industry associations.
