Financial entities across the EU are scrambling to interpret ESMA’s latest thematic notes on sustainability claims, and many are getting the fundamentals wrong. These misconceptions aren't just academic, they're leading to disclosure gaps that expose firms to greenwashing allegations and investor skepticism.
ESMA's guidance on impact and climate transition claims arrives when sustainability-related communications have become both ubiquitous and suspect. The notes don't create new regulatory obligations, but they clarify expectations that many CFOs and reporting officers have misunderstood. Here's what you need to correct before your next disclosure cycle.
Myth 1: Impact Claims Just Need a Positive ESG Score
Reality: Market participants understand positive environmental or social impact differently and attach different levels of ambition to their impact claims, according to ESMA's analysis. A fund with a high ESG rating isn't automatically making an impact claim, and simply adding an ESG score to a disclosure doesn't satisfy impact communication expectations.
ESMA expects you to explain three distinct elements: what difference you expect to make, how you aim to generate that positive impact, and how you'll measure results. If your current disclosure says "this fund supports sustainable development" without specifying whether you're measuring carbon reduction, employment outcomes, or water conservation, and without explaining your measurement methodology, you're not meeting the clarity standard.
The distinction matters because impact investing implies intentionality and measurability. Your disclosure needs to connect investment decisions to specific outcomes, not just portfolio composition.
Myth 2: Transition Claims Are Safe Because They're Forward-Looking
Reality: Climate transition claims are often forward-looking and subject to uncertainty, but that uncertainty doesn't excuse vague communication. ESMA's note highlights that transition claims depend on future actions, assumptions, and external factors, which means you need to disclose those dependencies, not hide behind them.
If you're claiming a portfolio is "aligned with net-zero transition," you must communicate what the transition ambition is, how it's expected to be implemented, and how progress will be assessed. This includes relevant assumptions, data limitations, and dependencies on factors outside your control.
Consider a bond marketed as supporting climate transition. If achievement depends on the issuer implementing specific operational changes by 2027, on carbon pricing reaching certain thresholds, or on technology availability, those conditions aren't footnotes. They're material to the claim itself.
Myth 3: Non-Regulatory Communications Have More Flexibility
Reality: ESMA's thematic notes specifically address non-regulatory communications, marketing materials, fund factsheets, website content, and investor presentations. The principle of clear, fair, and not misleading communication applies regardless of whether you're filing a mandatory regulatory disclosure or publishing a sustainability brochure.
The notes provide practical do's and don'ts illustrated through concrete examples based on observed market practices. ESMA isn't giving you leeway in marketing materials; it's closing the gap where firms have treated non-regulatory communications as less rigorous disclosure channels.
Your investor relations team can't make claims in a pitch deck that your regulatory filings don't support. If your SFDR disclosures are cautious and hedged but your fund marketing promises definitive impact, you've created a compliance exposure.
Myth 4: Following SFDR Means You're Already Compliant
Reality: ESMA's notes align with SFDR principles but don't prescribe a particular approach or level of ambition in the context of the ongoing SFDR review. They're observations intended to support your understanding of existing expectations, not a checklist that guarantees compliance.
SFDR establishes disclosure obligations for financial market participants. ESMA's thematic notes address how you communicate about sustainability, the clarity and balance of your claims, not just whether you've ticked required disclosure boxes.
You can file every mandatory SFDR template and still fail the "clear, fair and not misleading" standard if your communications create false impressions about impact or transition progress. The notes push you to evaluate whether investors receiving your disclosures would understand what you're actually claiming and what evidence supports it.
Myth 5: These Are Just Recommendations Without Enforcement Teeth
Reality: While the thematic notes don't create new regulatory requirements, they establish ESMA's expectations for market practices. National competent authorities across the EU use ESMA guidance when evaluating whether communications comply with existing obligations.
When an investor complaint or supervisory review questions whether your sustainability claims are misleading, authorities will reference these notes as evidence of what "clear and balanced" communication looks like. You're not facing a binary compliant/non-compliant assessment; you're being measured against evolving supervisory expectations.
The notes are part of ESMA's wider series promoting greater transparency and consistency in sustainability-related disclosures, following previous guidance on ESG credentials and ESG strategies. This isn't a one-off publication, it's a sustained regulatory focus that's shaping how supervisors evaluate your disclosures.
What to Do Instead
Start with a disclosure gap analysis focused specifically on impact and transition claims. Pull every external communication where you reference positive impact or climate transition, not just regulatory filings, but fund factsheets, marketing materials, and website content.
For each claim, map it to the three-part test: What difference do you expect to make? How will you generate that outcome? How will you measure results? If you can't answer all three with specificity, revise the claim or remove it.
For transition claims, document your assumptions explicitly. If your 2030 decarbonization pathway assumes specific policy changes, technology availability, or issuer actions, state them. If you're relying on third-party data with known limitations, disclose those limitations in the same communication as the claim, not buried in methodology appendices.
Create a sustainability claims review process that runs parallel to your legal and compliance review. Before any external communication goes out, someone needs to verify that sustainability language meets ESMA's clarity expectations. This isn't a legal review, it's a substantiation review.
Finally, stop treating impact and transition as marketing categories. They're disclosure categories with evidentiary requirements. If you can't substantiate the claim with your current measurement systems, you're not ready to make it publicly.
