Here’s a quick test you can run on any fund that calls itself “impact.” Ask one question: impact on what, exactly? If the answer is a shrug and a nice photo of a wind farm, you’ve found the problem Europe’s markets regulator just went after.
On 12 October, ESMA (the European Securities and Markets Authority, the EU’s markets watchdog) published two new notes on impact and climate transition claims. People are already calling them the ESMA impact claims guidance. So what do they actually say? Here’s the short version. If you market a fund or a bond as doing good, you’d better explain how. And you’d better measure it.
So what did ESMA actually publish?
Two short documents, which ESMA calls thematic notes. One covers positive impact claims made through funds and bonds. The other covers climate transition claims across funds, bonds and benchmarks.
They’re also part of a series. The first note, in July 2025, dealt with ESG credentials like labels, ratings and certificates. Then came a note on ESG strategies in early 2026. These two are numbers three and four.
Now the honest part: none of this is new law. ESMA says the notes “do not create new regulatory requirements.” Instead, they remind firms that what they say about sustainability has to be “clear, fair and not misleading.” Think of it as a regulator clearing its throat, loudly, in front of the whole room.
Every note in the series leans on four principles. Claims should be accurate, accessible, substantiated and up to date. ESMA also lists the classic ways a claim goes wrong: cherry-picking, exaggeration, omission, vagueness and even misleading imagery. So yes, that stock photo of a forest could be part of the problem.
The ESMA impact claims part, in plain English
Investor impact vs. investee impact
This is the big one. ESMA found that firms often mix up two different things. Investee impact is the good a company does, like a clinic that treats patients. Investor impact is the difference your money made, for example whether that clinic opened because you funded it.
But those aren’t the same thing. A fund can own shares in a great company without changing anything about it. According to ESG Today’s write-up, ESMA warns that blurring the two may make a claim misleading. If you want a refresher on the basics, our guide to social impact investing walks through it.
The do’s and don’ts
So what does ESMA want to see? First, name the environmental or social problem you’re targeting. Next, explain how the impact will happen and how you’ll track it, with KPIs on outputs, outcomes or impact. Then be clear about your ambition on intentionality (did you set out to do good?) and additionality (would it have happened anyway?).
The don’ts are short and a little brutal. Don’t use exclusion screens or ESG risk scores as a stand-in for impact. That’s the exact gap we covered in where screening ends and impact begins. And don’t call something “impact” just because of its sector or asset class. In other words, owning a solar company doesn’t make you an impact fund by default.
Why the transition part matters too
Transition claims are the “we’re getting greener over time” kind. They look forward, and ESMA admits they come with real uncertainty, since they depend on things like technology and public policy. But uncertainty isn’t an excuse to be vague.
This isn’t a niche issue, either. As of early 2026, 413 funds used transition-style words like “improve,” “progress” or “net-zero” in their names. Together they held roughly EUR 230 billion. In fact, the number of UCITS funds (the standard EU retail fund type) using those words jumped from 220 to 334 in a year.
The transition note includes a nice pair of examples. The good one: a fund aiming to cut the carbon intensity of its portfolio by 30% by the end of 2029, against a 2024 baseline. It names the metric and the emission scopes. It also says plainly that this isn’t a real-economy target. The poor one: a fund promising 80% of its money goes to “transition leaders,” while never saying what a transition leader is.
Our favorite line is a simple don’t. Don’t present a cleaner portfolio as if it equals cleaner air. Selling a polluter’s shares to someone else makes your numbers look better, but it doesn’t stop a single tonne of emissions.
Okay, but should you care about ESMA impact claims?
If you’re an everyday investor, yes, a little. These notes hand you a ready-made checklist. Ask any “impact” or “transition” fund four things. What problem are you solving? How does my money change anything? What’s the number you track? And how did you do last year?
That last question is where plenty of firms go quiet. ESMA found fewer examples of firms reporting regularly on progress against their own targets. It’s the same reason we tell readers to look past headline ESG ratings and ask for the actual numbers.
For us in Armenia and other emerging markets, there’s a practical angle too. If your social enterprise or green project hopes to raise money from European funds, expect sharper questions. Investors will want your KPIs, your baseline and a clear story of what changes because of them. Honestly, that’s good news. Projects that already measure their results will stand out.
The question we’d keep asking
Is this the end of impact-washing? No. The notes are guidance, not fines, and ESMA says it isn’t prescribing any level of ambition. They also sit next to the ongoing review of SFDR, the EU’s main sustainable-finance disclosure rulebook. ESMA says more notes will follow as needed.
Still, the ESMA impact claims notes change the default question. It’s no longer “does this sound good?” Instead, it’s “can you prove it?” And that’s a question every fund, and every founder chasing impact money, should be ready to answer.
