The Role of ESG Reporting in Long-Term Business Valuation
Updated September 2, 2026 · 4 min read
- ESG reporting requirements diverged sharply in 2026: the US SEC voted to rescind its climate disclosure rule, while the EU’s CSRD stayed in force but got a much narrower scope.
- The EU’s Omnibus package raised CSRD thresholds to 1,000+ employees and €450M+ turnover, cutting the number of covered companies by roughly 90%.
- Even where mandates shrink, ESG reporting still affects business valuation through investor expectations, supply-chain requirements, and access to capital.
- Companies still voluntarily reporting are increasingly doing it for competitive and financing reasons, not just compliance.
ESG reporting requirements took very different paths in the US and EU during 2026. The SEC voted in May 2026 to propose fully rescinding its climate disclosure rule — a rule that was adopted in 2024, immediately stayed, and never actually enforced. The EU’s Corporate Sustainability Reporting Directive (CSRD), by contrast, remains legally in force, but a 2026 “Omnibus” simplification package cut its scope dramatically.
What Changed in 2026, Side by Side
| Jurisdiction | 2026 status | Key detail |
|---|---|---|
| United States (SEC) | Rescission proposed May 29, 2026 | Rule was never enforced after being stayed shortly after its 2024 adoption |
| European Union (CSRD) | Remains in force, scope narrowed | Omnibus package raised thresholds to 1,000+ employees / €450M+ turnover |
| EU CSDDD (due diligence directive) | Also narrowed | Part of the same Omnibus I package |
The EU’s threshold change alone is estimated to reduce the number of companies covered by both directives by roughly 90% — a dramatic scope reduction while keeping the underlying reporting framework intact for the largest companies.
Why ESG Reporting Still Matters for Valuation
Regulatory retreat doesn’t erase the business case. Even companies no longer legally required to report climate and sustainability data face pressure from three other directions:
- Investor expectations — many institutional investors kept their own ESG screening criteria regardless of what regulators require.
- Supply-chain requirements — large companies still covered by CSRD often push reporting requirements down to smaller suppliers contractually, even if those suppliers aren’t legally mandated to report.
- Access to capital — sustainability-linked loans and green bonds typically still require some form of ESG disclosure regardless of statutory mandates.
The Compliance Cost Argument
| Argument | 2026 reality |
|---|---|
| “Rules are shrinking, so reporting cost drops” | True for smaller/mid-size firms newly excluded from CSRD scope |
| “No mandate means no need to report” | Partially true — but investor and supply-chain pressure often persists independently |
| “US companies can ignore ESG entirely now” | Risky assumption for companies with EU operations, EU customers, or EU-based investors |
Who Still Needs to Pay Attention
Any company with meaningful EU revenue, EU-based large customers, or EU operations still needs to track CSRD compliance even after the Omnibus scope reduction — the largest companies remain fully in scope. US-only companies without EU exposure have genuinely more breathing room after the SEC’s proposed rescission, though voluntary reporting pressure from investors hasn’t disappeared.
One-Minute Recap
- SEC proposed fully rescinding its (never-enforced) climate disclosure rule in May 2026.
- EU’s CSRD stayed in force but now covers roughly 90% fewer companies after the Omnibus threshold change (1,000+ employees, €450M+ turnover).
- Investor, supply-chain, and financing pressure keep ESG reporting relevant even where mandates shrink.
- EU-exposed companies still need to track compliance closely; US-only companies have more flexibility now.

Is the SEC climate disclosure rule still in effect?
No. It was adopted in 2024, stayed almost immediately, and never enforced. In May 2026 the SEC voted to propose fully rescinding it.
Is the EU’s CSRD still mandatory in 2026?
Yes, but with a much narrower scope. A 2026 Omnibus simplification package raised the thresholds to companies with 1,000+ employees and over €450 million in annual turnover, cutting the number of covered companies by roughly 90%.
Do smaller companies still need to do ESG reporting?
Legally, many smaller companies are now excluded from CSRD after the 2026 threshold changes. Practically, some still report voluntarily due to investor expectations or because a larger customer requires it contractually.
Does ESG reporting still affect company valuation?
Yes, through investor screening criteria, access to sustainability-linked financing, and supply-chain requirements from larger partners — even in jurisdictions where legal mandates have shrunk or disappeared.
What is the EU Omnibus package?
A 2026 EU legislative package that simplified and narrowed the scope of both the CSRD (sustainability reporting) and CSDDD (due diligence) directives, raising the size thresholds for which companies must comply.
Should a US-only company stop worrying about ESG reporting?
It has more legal flexibility now that the SEC has proposed rescinding its climate rule, but investor and financing pressure for voluntary disclosure hasn’t disappeared, especially for companies seeking sustainability-linked capital.
