ESG Ratings
As consumer demand for clean energy grows, demonstrating sustainability fosters customer loyalty and strengthens our green-focused positioning. Presenting sustainable performance is vital for regulatory compliance, attracting green investments, and building a positive reputation — aligning the company with environmental laws and helping secure financing from ESG-focused investors.
ESG ratings are assessments given to companies or financial instruments based on their adherence to Environmental, Social and Governance criteria. They have gained increasing influence in global capital markets, as investors, borrowers, and issuers rely on them to make well-informed, sustainable investment and financing decisions.
The Regulation (EU) 2024/3005 on the transparency and integrity of ESG rating activities entered into force on 8 January 2025 and applies to authorised ESG rating providers from 2 July 2026. It establishes a common regulatory framework to enhance the reliability and comparability of ESG ratings across the EU, by requiring providers to:
- operate under ESMA authorisation and supervision;
- publish their methodologies, models and key rating assumptions;
- implement structural safeguards to prevent conflicts of interest between rating and advisory activities.
ESG scores are an essential tool for EDP, enabling measurement of the company's ESG risk exposure, sustainability performance and long-term value creation. They contribute to the continuous improvement of our operations and foster trust and confidence among investors and other stakeholders. We disclose below the ratings and scores from providers whose methodologies permit public disclosure.

In the latest S&P Global Corporate Sustainability Assessment (CSA) (2025 Methodology), EDP achieved a total ESG Score of 87/100, ranking in the 96th percentile among the 250 companies assessed in the Electric Utilities (ELC) industry—significantly above the industry average of 41 points. The scores across the three dimensions were: Environmental 89/100 (96th percentile), Social 86/100 (93rd percentile), and Governance & Economic 83/100 (97th percentile).
EDP achieved maximum scores of 100/100 in the criteria Community Relations, Transparency & Reporting, Privacy Protection and Materiality, and 99/100 in Climate Strategy—one of the most heavily weighted criteria (11/100), alongside Product Stewardship (13/100) and Human Capital Management (8/100). Data availability was rated as Very High, with disclosure rates of 99% for mandatory public disclosure and 100% for additional disclosure.
The company also improved its performance in areas such as waste and pollutants, water management, and risk and crisis management. EDP has already achieved an 88% reduction in water consumption, surpassing its 2025 target of 78%. Circular economy practices and digitalisation initiatives have supported a continuous reduction in waste over the past four years.
Today, around 90% of EDP’s total electricity generation comes from renewable sources, a profound shift compared with 2005, when 80% of generation relied on fossil fuels. The company’s decarbonisation trajectory is equally significant: emissions intensity decreased from 230 gCO₂/kWh in 2019 to 45 gCO₂/kWh in 2025, with a target of 15 gCO₂/kWh by 2028, while revenues from coal are now close to zero.
EDP remains committed to achieving carbon neutrality by 2040, supported by a €12 billion investment plan for 2026–2028, fully allocated to Renewables and Electricity Networks. From a financial perspective, green financing already represents 81% of total debt, with a target of over 90% by 2028—well above the 60% green financing target set for 2026, which has already been exceeded.
Based on the 2025 CSA assessment, EDP was included in the S&P Global Sustainability Yearbook 2026 (released on 18 February 2026) with the distinction Top 5%. Out of more than 9,200 companies assessed globally, only 848 were included in the Yearbook, and just 64 achieved the Top 5% distinction. EDP is one of only six Electric Utilities worldwide to receive this recognition and the only Portuguese company in this elite group within the sector.
Notably, only two Electric Utilities globally achieved the highest distinction of Top 1% (Redeia and Terna), placing EDP in the second-highest level of recognition within the Yearbook.
EDP’s long-standing inclusion in the Dow Jones Best-in-Class Indices since 2006 reflects its consistent commitment to the energy transition, technological innovation and tackling climate change.

Out of 27 criteria, EDP excelled in 8, scoring 100 points each: Market Opportunities, Water Related Risks, Innovation Management, Materiality, Policy Influence, Environmental Reporting, Social Reporting, and Corporate Citizenship/Philanthropy.

On December 9, EDP was selected for the DJSI World and Europe indices. This highlights EDP's leadership in ESG aspects.
The strongest ESG areas were Governance & Economic (+7 points) and Social (+4 points). EDP ranked in the top 2 for environment, top 3 for governance & economic, and top 4 for social. In 8 out of 27 criteria, EDP achieved the maximum score, being “Best in Class.”
This index rigorously evaluates companies' sustainability performance and market trend adaptation. EDP scored 85 points, 4 points lower than in 2017, yet 39 points above the industry average. EDP excelled in the social dimension with the industry's highest score of 89 points.
In the integrated utilities category, EDP dropped from first to second, and in the global electrical industry ranking, from second to fourth. Contributing to this drop were criteria like Customer Relationship Management and Operational Eco-Efficiency.
The inclusion of a company in these indexes brings it many benefits, both of a tangible and intangible nature. In addition to a public recognition of leadership in strategic areas of economic, environmental, and social dimensions, there is also the important recognition by those who are using ESG data, like asset owners, asset managers, regulators, and banks.
In general terms, it gives us brand reputation, contributes to reinforcing employee relations, retains talent and improves our stakeholder relations. In particular, the effort of entering the Dow Jones Sustainability Indexes also allows the design of clear and precise objectives in terms of sustainable operations.
The constant evaluation of the company and the updating of the criteria creates undeniable rigor in all areas of operations for the Group.
The company’s practices, assessed for inclusion in indexes, include such areas as:
- Value Creation (creating value for the Shareholder, increase in productivity and efficiency; commitment to focusing on the Client);
- Efficient use of resources;
- Environmental and Biodiversity Protection;
- Integrity;
- Dialogue with stakeholders (open and transparent relationships with clients, investors, suppliers, and employees; credible reporting on the company’s performance in all areas);
- Human Capital Management (implementing systems to ensure the health, safety and welfare of employees, the promotion of the development of capabilities, and the rejection of abusive and discriminatory practices);
- Promoting access to energy;
- Support for Social Development.

The DJSI allow the creation of portfolios of companies that fulfil certain sustainability criteria better than most of their peers within a given industry.
The DJSI benchmarks are comprised of three geographical breakdowns: DJSI World, DJSI Regions, and DJSI Countries. Indices within these geographical divisions use different starting universes and different percentiles to mark the cutoff point in selecting the most sustainable companies.
