Net-zero / carbon-neutrality target

Weighted
4.2/7
3

JERA has a JERA Zero CO₂ Emissions 2050 commitment. The report states that JERA aims to achieve net-zero CO₂ emissions from domestic and overseas operations by 2050, using a “smart transition” approach combining renewable energy and zero-CO₂-emission thermal power.

Interim decarbonisation target

Weighted
5.6/7
4

JERA has interim domestic decarbonisation targets for FY2030 and FY2035. By FY2030, JERA aims to decommission all inefficient coal power plants, conduct ammonia substitution demonstrations at high-efficiency coal plants, promote renewable energy centred on offshore wind, and reduce thermal power carbon emission intensity by 20% based on Japan’s FY2030 long-term energy supply-demand outlook. By FY2035, JERA aims to reduce domestic business CO₂ emissions by at least 60% compared with FY2013.

JERA discloses Scope 1, Scope 2 and Scope 3 emissions in its pre-financial data. FY2024 Scope 2 emissions were 177 thousand tCO₂ under both location-based and market-based methods, while Scope 3 emissions were 32,390 thousand tCO₂. Scope 3 is broken down by category, including Category 1 purchased goods and services: 160 thousand tCO₂, Category 2 capital goods: 888 thousand tCO₂, Category 3 fuel- and energy-related activities: 20,376 thousand tCO₂, and Category 11 use of sold products: 10,625 thousand tCO₂.

Renewable / OSW growth commitment

Weighted
7/7
5

JERA’s 2035 growth strategy sets a target of 20 GW renewable energy development output by FY2035, with renewable energy identified as one of the three strategic pillars alongside LNG and hydrogen/ammonia. The report also shows current renewable energy development capacity of approximately 4.6 GW as of June 30, 2025. For OSW specifically, JERA Nex bp is described as a strategic offshore wind platform with approximately 13 GW net potential generating capacity, and JERA and bp have agreed to invest up to US$5.8bn by the end of 2030.

Absolute emissions progress vs baseline

Weighted
4.8/8
3

JERA uses FY2013 as the baseline for its domestic decarbonisation pathway. The report shows domestic business CO₂ emissions of approximately 180 million tCO₂ in FY2013 and 126 million tCO₂ in FY2024, with a commitment to reduce domestic business CO₂ emissions by at least 60% by FY2035 and reach net-zero CO₂ emissions by 2050.

EU Taxonomy / regulatory alignment

Weighted
3/5
3

No clear EU Taxonomy disclosure is provided in the JERA Integrated Report. This is understandable because JERA is a Japan-based energy company rather than an EU-headquartered issuer. Instead, the report references frameworks such as TCFD, TNFD, GRI Standards, Japan’s Environmental Reporting Guidelines 2018, and the International Integrated Reporting Framework.

Water and environmental compliance

Weighted
2.4/4
3

JERA reports environmental management in terms of reducing CO₂ emissions, preventing air and water pollution, biodiversity conservation and compliance with environmental laws and regulations in each country and region. The TNFD-related analysis also identifies water as a key natural-capital dependency and impact across coal procurement, LNG procurement, thermal power, solar, wind and biomass power generation.

Asset-level OSW project evidence

Weighted
8/10
4

JERA Nex bp’s offshore wind portfolio includes operating assets and development projects with approximately 13 GW net potential generating capacity. External JERA Nex bp information states that this includes around ~1 GW of operational offshore wind projects, 7.5 GW of development projects, and 4.5 GW of secured leases. The report also identifies JERA’s past and current OSW activity: participation in Taiwan’s first commercial-scale offshore wind projects Formosa 1 and 2, completion of Japan’s first large-scale offshore wind project Ishikari Bay New Port, and selection as operator for multiple Japanese offshore wind projects including Oga, Katagami and Akita City. JERA’s official project page also states that Formosa 2 consists of 47 fixed-bottom offshore wind turbines off Taiwan’s north-western coast.

Marine ecology and biodiversity mitigation

Weighted
4.8/8
3

The report does not provide detailed OSW asset-level marine ecology mitigation comparable to Vattenfall’s Hollandse Kust Zuid or Iberdrola’s Baltic Eagle examples. However, JERA reports nature-related risk assessment using the TNFD LEAP approach, including identification of priority locations through IBAT and other tools, and analysis of dependencies/impacts for wind power generation, including land use, underwater areas, water consumption, pollution, solid waste and disturbance.

Nature-positive / biodiversity target

Weighted
1.6/4
2

JERA participates in Japan’s 30by30 Alliance for Biodiversity, which aims to conserve more than 30% of land and sea areas by 2030 and support a path toward a nature-positive future. The report states that JERA applies the mitigation hierarchy, avoidance, minimisation and restoration, when constructing and replacing power plants. It also reports that Kurihama Forest at Yokosuka Power Station, a 10.5-hectare green space, was certified as an OECM in FY2024, and that a 2024 survey identified 32 plant species and 235 animal species at the site.

Circularity and end-of-life wind asset mgmt

Weighted
2.4/4
3

The report gives limited wind-specific circularity evidence. It identifies recycling and resource recovery as part of JERA’s natural capital and recognises solid waste as a nature-related impact across relevant business activities, but it does not disclose a quantified wind-blade, turbine-component, or OSW end-of-life circularity target.

Low-carbon materials / embodied carbon

Weighted
1.6/4
2

The report provides strong evidence on low-carbon fuels, especially hydrogen, ammonia and CCS/CCUS, but limited evidence on low-carbon construction materials such as steel, concrete, cables or foundations for OSW. JERA completed the world’s first demonstration test substituting 20% ammonia at a large-scale commercial coal-fired power generator and is preparing for commercial operation; it also started commercial use of electricity generated by 100% hydrogen-fuelled zero-CO₂-emission thermal power for Toho Studios. For OSW embodied carbon, no quantified low-carbon steel/concrete commitment was found in the report.

M14Governance & Accountability

Supplier screening and due diligence

Weighted
4.8/8
3

JERA reports responsible procurement and supplier-related governance mainly through compliance and human rights due diligence. The report states that JERA is committed to responsible procurement considering CSR and ESG factors, including quality assurance, procurement cost management, legal compliance, safety assurance and business continuity planning. It also states that JERA is establishing a human-rights due diligence framework based on the UN Guiding Principles on Business and Human Rights, the OECD Due Diligence Guidance, and Japan’s guidelines on responsible supply chains. In FY2024, JERA conducted a company-wide employee survey covering areas such as the supply chain and human rights.

External validation, assurance and ratings

Weighted
7.2/12
3

JERA’s Integrated Report references GRI Standards, TCFD and TNFD recommendations, and the report notes that FY2024 environmental data marked with a star has been externally assured. It also provides links to an Independent Assurance Report on Environmental Data. Externally, JERA states that it has been responding to the CDP climate change questionnaire since 2022, but Not clearly disclosed in the reviewed materials.
