Not one regime
A US manager or corporate looking for the applicable climate disclosure rule finds several partial answers rather than one.
State requirements. Certain states have enacted their own climate reporting requirements, with thresholds based on revenue and on doing business in the state. Their reach extends well beyond companies headquartered there.
Foreign regimes. A US manager marketing into Europe, or a US corporate with European operations or listed securities, may fall within European sustainability reporting and marketing rules regardless of where it is based.
Investor requirements. Large asset owners impose their own reporting obligations contractually. For many managers this binds earlier and harder than any regulation.
Antifraud. Whatever the disclosure framework, statements made to investors are subject to securities antifraud law. A sustainability claim that cannot be substantiated is a misstatement risk, and this is the most consistent source of enforcement exposure.
The practical consequence
The disclosure question is not "what does the regulator require" but "what have we told investors, what can we substantiate, and which regimes reach us". The second and third have answers today.
Building something durable
- Inventory commitments already made: in marketing materials, side letters, questionnaires, and fund documents. These are the enforceable ones
- Assess extraterritorial reach specifically, rather than assuming a US-domiciled structure is out of scope
- Build data collection at the portfolio level to a standard that can be audited; retrofitting it is expensive
- Keep the substantiation file: methodology, sources, and the basis for each claim
- Write commitments you can meet; the difference between an aspiration and a commitment must be visible in the language
Where this is heading
Requirements are diverging rather than converging, and a manager operating across jurisdictions should expect to report to more than one framework for the foreseeable future. The efficient response is a single internal data set built to the strictest applicable standard, from which each report is produced — rather than parallel processes that will eventually contradict each other.
