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. It aligns the company with environmental laws and helps secure financing from ESG-focused investors.
ESG Ratings are assessments given to companies or financial instruments based on their adherence to ESG criteria. The current major challenge faced by companies is the quality and comparability of these ratings. ESG ratings 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.
ESG ratings are used as inputs for EUR 3,787 billion (i.e 48% of total assets under management), according to ESMA ESMA Call for evidence on market characteristics of ESG Rating, June 2022.
The Proposal for a regulation of the European Parliament and the Council on the transparency and integrity of Environmental, Social and Governance (ESG) rating activities aims to enhance the reliability and comparability of ESG ratings by introducing a common regulatory approach to improve the transparency and integrity of ESG ratings providers' operations and prevent potential conflicts of interest.
Some aspects of the new ESG rating regulation: a) Under the new regulation European Securities and Markets Authority (ESMA) will be responsible for developing the secondary legislation/ Regulatory Technical Standards (RTS) which will further clarify the responsibilities of authorised ESG Ratings providers under the new regime; b) Providers must publish on their website the methodologies, models and key rating assumptions they use in their ESG rating activities.
ESG scores are an essential tool for EDP, facilitating the measurement of the company’s ESG risk, ESG performance and long-term ESG value creation, contributing to the continuous improvement of its operations, and fostering trust and confidence among investors and other stakeholders. We follow the ESG rating providers which allow us to disclose the ESG ratings/scores on the table below.

The DJSI allow the creation of portfolios of companies that fulfill 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.
The Data Providers/Index Providers are one of the main providers of non-financial information. The ESG rating market is very dynamic and these providers of non-financial information increasingly offer a diverse set of products and services to investors (e.g. ESG ratings, sustainability indices, controversy alerts, etc.).
