Deep Dive

The European Securities and Markets Authority (ESMA) has just dropped a draft of its Regulatory Technical Standards (RTS) under the EU’s ESG Rating Regulation. These proposed rules aim to bring more clarity, transparency, and trust to the world of ESG ratings, an area that has seen rapid growth but little oversight, until now.

It all started back in 2021, when ESMA raised alarms about the lack of regulation surrounding ESG ratings. With billions of euros flowing into sustainable investments, ESMA was concerned that investors had no way of knowing just how reliable or consistent these ratings were. The EU responded by introducing its Sustainable Finance Strategy, with one of its key objectives being to clean up the ESG ratings market. The result? A regulation now in place, and ESMA tasked with designing the rules that would bring order to the chaos.

What exactly do these draft RTS propose, you might ask? The short answer is a lot of safeguards and requirements designed to create a more structured, transparent, and reliable ESG ratings landscape. Here are the key highlights:

• A Clearer Path for Authorization: For the first time, ESG rating providers will have clear guidelines on what they need to submit when applying for official recognition or authorization. Whether they’re based in the EU or outside, providers will be required to meet the same set of standards for transparency and accountability. Non-EU providers, however, will face some extra hoops to jump through when seeking recognition.
• Keeping Conflicts of Interest in Check: One of the biggest concerns with ESG ratings has been the potential for conflicts of interest. ESG ratings agencies may also offer consulting or advisory services, creating the risk of bias in their assessments. The proposed rules require providers to separate their ESG ratings activities from other services—no more dual roles. ESMA is emphasizing that this separation must be real, not just a box-ticking exercise, to ensure that the integrity of the ratings process isn’t compromised.
• More Transparency with Disclosures: Transparency is at the heart of the proposed rules. ESG rating providers will need to disclose their methodologies, rating models, and key assumptions behind their ratings. This isn’t just a technical detail, it’s essential for helping users understand how ratings are formed and for making sure that ESG assessments can be compared across providers.

The consultation period for these draft rules is now open until June 20, 2025, and ESMA is keen to hear from anyone with a stake in the ESG ratings market. Whether you’re a rating provider, a financial market participant, or an issuer who’s been rated, this is your chance to weigh in on the regulatory framework that could shape the future of ESG ratings in the EU.

After the consultation wraps up, ESMA will carefully consider all the feedback and work toward publishing a final report. The aim is to have the finalized draft RTS submitted to the European Commission by October 2025.

This is more than just regulatory housekeeping. The changes ESMA is proposing have the potential to reshape the entire ESG ratings ecosystem. By putting stricter rules in place, ESMA is setting the stage for a market where ratings are more transparent, reliable, and trustworthy—key factors for investors and market participants. For those involved in sustainable finance, this regulatory overhaul is an opportunity to help ensure that ESG ratings can live up to their potential in guiding responsible investment decisions.

As the EU takes these steps to clean up the ESG ratings market, the hope is that it will help build stronger investor confidence in sustainable investments, ultimately supporting Europe’s wider green finance goals and aiding the transition to a more sustainable economy. This is a space to watch closely, as the coming months will likely bring more clarity, better standards, and, most importantly, more trust in ESG ratings.
