ESG US/UK/EU/China: A Board of Directors Compass

Amid the ongoing geopolitical fragmentation, a board of directors with international operations can no longer manage its ESG compliance off a single framework. Look at four major jurisdictions — the US, the UK, the EU, China — and it’s hard to miss that each is now on an openly divergent track: federal rollback, consolidation through internal governance, mandatory simplification, and gradual codification. This is not a minor technical disagreement between regulators; it exposes directors to legal risks that are, in some cases, directly opposed depending on the jurisdiction in which they sit or invest. Understanding this fragmentation has become a governance prerequisite, on par with financial risk oversight or reputational risk management. This article offers a jurisdiction-by-jurisdiction reading to help directors arbitrate between compliance, financial materiality, and litigation risk management.

1. United States: federal deregulation and a fiduciary-duty battleground

The US landscape in 2026 is defined by federal regulatory retreat combined with a rising wave of private litigation. The Securities and Exchange Commission formally proposed, on May 29, 2026, to rescind in its entirety the 2024 climate-related disclosure rule, which never took effect because of litigation before the US Court of Appeals for the Eighth Circuit (SEC official statement). SEC Chair Paul Atkins justified the move by arguing that disclosure obligations should be guided strictly by financial materiality rather than by an implicit attempt to dictate corporate behavior. This federal deregulation, however, does not exempt multinational boards from a differentiated compliance map: several US states maintain their own climate-reporting requirements, and US subsidiaries of European groups remain subject to the CSRD once they cross the applicable thresholds — a dual-track reality that Ksapa detailed early on when it first mapped how SEC rules compare with CSRD, ESRS and IFRS, and later revisited when analysing how EU and US climate disclosure regimes diverge in scope and ambition.

A second, more structurally significant front is playing out in federal courtrooms on fiduciary duty under the Employee Retirement Income Security Act (ERISA). The ruling handed down by Judge Reed O’Connor in Spence v. American Airlines marked a turning point: the court found that the airline had breached its duty of loyalty by allowing BlackRock to exercise proxy voting and shareholder engagement shaped by ESG considerations, without sufficient oversight from the plan’s fiduciary committee. The final judgment, issued on September 30, 2025, awarded no monetary damages for lack of demonstrated financial harm, but it imposed a permanent injunction barring American Airlines from allowing any proxy voting motivated by non-pecuniary considerations (Bloomberg Law analysis). This precedent opens the door to further private litigation against fiduciaries of retirement plans who delegate voting policy without documented oversight — a risk that runs directly counter to the expectations European institutional investors place on the very same boards, where the absence of a responsible-voting policy is increasingly treated as a governance red flag rather than a safe default.

For a board sitting across both US and European mandates, this divergence is not academic. It calls for an explicit, jurisdiction-specific differentiation of shareholder-engagement policy and retirement-plan governance, documented and justified case by case rather than driven by a single global ESG principle — an exercise Ksapa has examined through the lens of applying Total Cost of Ownership thinking to ESG investment, which distinguishes the strategic value of ESG programs from administrative overreach poorly calibrated to actual risk. This US recalibration also sits within a broader climate of regulatory fragmentation: Ksapa’s own reporting-harmonization work, warned years ago that without coordination between national and regional regulators, the world risked ending up with sharply divergent reporting standards across major markets — a prediction that has largely materialized, as detailed in Ksapa’s overview of global ESG reporting standards taking shape. More recently, the SEC’s threat to restrict the use of IFRS accounting standards by foreign issuers over their sustainability content illustrates how far this fragmentation now extends beyond disclosure rules into the architecture of global capital markets themselves, a dynamic Ksapa examined closely in its analysis of the SEC’s threat to global market access. On governance mechanics specifically, the board-level oversight structures already tested under the CSRD — dedicated sustainability committees, defined accountability lines, systematic reporting to the full board — remain broadly transferable to a US context, provided they are reframed around financial materiality rather than double materiality, as Ksapa outlines in its guidance on the critical role of boards of directors in CSRD implementation.

2. United Kingdom: consolidation through internal governance rather than statute

The United Kingdom is charting a distinct course — neither aligned with the American retreat nor with binding EU-style codification. Rather than legislating a new mandatory climate-reporting regime, the UK is consolidating a market-led framework built around internal board governance. The central provision driving this shift, Provision 29 of the UK Corporate Governance Code (2024 edition), now requires boards to make a formal declaration on the effectiveness of their material internal controls, both financial and non-financial. The provision applies to financial years beginning on or after January 1, 2026, with the first effective reporting expected in 2027, as confirmed in the current version of the UK Corporate Governance Code published by the Financial Reporting Council.

Contrary to a comparison sometimes drawn with the US Sarbanes-Oxley Act, Provision 29 requires no external auditor attestation: the board itself formulates its declaration based on its own risk review and control framework, operating on a “comply or explain” basis. In parallel, the UK government is establishing an interim, non-statutory oversight regime for sustainability-assurance practitioners, run by the Financial Reporting Council, ahead of a future statutory regime — a deliberately graduated, profession-led architecture rather than one imposed directly by law, as detailed in Macfarlanes’ corporate law update.

For boards of groups with both UK and EU operations, this approach demands a dual reading. On one hand, the material-controls declaration must be underpinned by ESG data governance robust enough for directors to personally stand behind it — an exercise that closely mirrors the double-materiality oversight responsibilities already tested under the CSRD, where the board’s fiduciary duty of loyalty and care extends explicitly to climate and human-rights risk oversight, as Ksapa lays out in its analysis of board duties on ESG: managing climate and human rights risks. On the other hand, the absence of a UK equivalent to the CSRD’s binding disclosure regime means UK subsidiaries of continental groups are, strictly on UK-only grounds, exempt from an obligation their parent company continues to carry at the consolidated group level — a gap boards must document explicitly in their governance mapping, echoing points Ksapa raised when comparing the CSRD and EU ESRS standards with other reporting regimes companies must reconcile. This governance-led model — regulation through board accountability rather than statutory disclosure mandates — represents a genuine third path, distinct from both the US federal retreat and the EU’s binding, if recalibrated, codification.

3. European Union and China: two codification tracks advancing at different speeds

Where the US is dismantling and the UK is consolidating through governance, the EU and China share a structural commonality: both continue to advance toward binding legal reporting obligations, without abandoning them, but with significantly adjusted timelines and scope.

On the European side, the Omnibus I simplification package, formally adopted and published in the Official Journal of the European Union on February 26, 2026, substantially recalibrated the CSRD and the CSDDD without repealing either. Member states have one year from entry into force to transpose the directive into national law. Critically, the European Commission adopted revised, shorter ESRS standards on July 3, 2026, alongside a new voluntary reporting standard for companies outside the CSRD’s scope, and introduced an explicit cap on the information large companies can request from value-chain partners (official European Commission announcement). Ksapa has tracked this trajectory closely — from its early breakdown of the 12 ESRS standards driving CSRD reporting, through its assessment of how the CSDDD is being recalibrated under the provisional political agreement, to a more critical read of why businesses are now divided over the diluted directive — particularly its abandonment of a harmonized civil-liability regime, a meaningful retreat from the directive’s original ambition. National due-diligence laws that predate the EU directive, from France’s duty of vigilance to Germany’s LkSG, continue to generate their own case law in parallel, and Ksapa observes that mediation is increasingly emerging as a pragmatic alternative to litigation in a growing share of these disputes, as explored in its ten-year review of corporate due diligence and whether mediation is the missing piece.

On the Chinese side, the trajectory is one of steady, deliberate escalation. China’s three stock exchanges — Shanghai, Shenzhen, and Beijing — have put in place mandatory ESG reporting guidelines for large-cap and dual-listed issuers effective from 2026, building on the foundational disclosure standards published by China’s Ministry of Finance in December 2024. Over 400 large listed companies are required to publish their first mandatory sustainability report covering the 2025 financial year, with full-framework rollout targeted for 2030 (China Briefing analysis). Ksapa followed the publication of China’s first climate standard closely, noting that China’s ESG reporting architecture is evolving rapidly from conceptual frameworks toward genuinely enforceable requirements, creating both risk and opportunity for multinationals with Chinese operations or supply chains, as detailed in its analysis of China’s Climate Standard: CSDS in Action. This progressive codification echoes the earlier call for coordinated global standards that Ksapa raised years before any of these frameworks existed, in its foundational piece on why global ESG reporting standards needed to be harmonized rather than developed in silos.

For a board, this dual codification dynamic requires a different prioritization exercise than the one triggered by US retreat or UK governance-led consolidation: the question is no longer whether a binding obligation will exist, but how to anticipate its timeline and stringency, and how to build data architecture once, for reuse across multiple frameworks rather than duplicating collection efforts jurisdiction by jurisdiction.

What this means for board governance

The practical takeaway for an internationally active board is not to select a single global ESG standard to apply uniformly, but to build a differentiated compliance governance model, mapped and justified jurisdiction by jurisdiction. That means cataloguing, subsidiary by subsidiary, the regime that actually applies — federal deregulation paired with a distinct fiduciary-duty risk in the United States, board-led internal-controls declarations in the United Kingdom, binding but recalibrated codification in the European Union, and steadily escalating mandatory disclosure in China — rather than steering compliance from a single top-down ESG principle. It is this differentiated approach, rather than a unified global standard, that will let directors turn regulatory fragmentation from an unmanaged risk into a genuinely governed one.
