Overview

Say too much, and you may face a greenwashing lawsuit. Say too little, and you’ll be accused of hiding your impact.

This is the paradox of corporate sustainability in 2026. Across jurisdictions, businesses face legal, financial, and reputational risks for both action and inaction. What was a communication issue is now a strategic risk, as A&O Shearman’s ESG outlook notes.

The New ESG Minefield

Companies today face a tightening vice: increasing scrutiny over what they say and growing suspicion when they say nothing at all.

This tension has given rise to “greenhushing”- a deliberate scaling back of ESG disclosures to avoid legal exposure. The phenomenon is increasingly discussed in legal and policy circles, including in LegalClarity’s overview of ESG controversies. While initially concentrated in Western markets, similar pressures are now emerging across Asia and Latin America.

Greenwashing: From Marketing Risk to Legal Liability

Greenwashing is no longer a reputational issue, it is becoming a legal one, with real financial and criminal consequences.

Legal scrutiny is accelerating globally. For example, Forward Law Review’s analysis of ESG litigation highlights how enforcement is evolving from misleading marketing claims toward potential fraud liability.

Several high-profile cases illustrate this shift:

•     DSW was fined €25 million by German prosecutors for overstating ESG credentials

•      Apple successfully defended its “carbon neutral” claims, showing the high evidentiary bar required for consumer deception.

•      Santos (Australia) prevailed in a landmark case over emissions target disclosures.

At the regulatory level, the UK’s Economic Crime and Corporate Transparency Act 2023 introduces a strict liability “failure to prevent fraud” offence (effective September 2025), a development discussed in Fieldfisher’s ESG litigation overview.

Meanwhile, the United States continues to experience a surge in class actions, underscoring that ESG claims must now be supported by robust evidence.

The Anti-ESG Counterattack

Greenwashing litigation is increasingly being used not just to enforce ESG integrity but to challenge ESG itself.

According to PracticalESG’s analysis of anti-ESG legal strategies, multiple U.S. state attorneys general have challenged major technology companies over Renewable Energy Certificate (REC) claims, arguing these do not meaningfully increase renewable energy production.

Similarly, high-profile cases such as Texas v. BlackRock Inc. reflect a broader trend: ESG commitments are being framed as potential antitrust or market manipulation concerns.

The result is a growing paradox - greenwashing claims are being used both to strengthen and to suppress ESG activity.

Asia’s Growing Exposure

Asia is rapidly becoming a focal point for ESG enforcement and regulatory development.

As global expectations converge, regulators across the region are tightening oversight of sustainability disclosures. This aligns with broader trends identified in Watson Farley & Williams’ analysis on rising greenwashing risks, which highlights increasing scrutiny across jurisdictions.

Singapore, China, Australia, and New Zealand are all strengthening their approach particularly around ESG fund disclosures, net-zero claims, and the credibility of sustainability data.

Greenhushing: When Silence Becomes Strategy

Faced with rising legal exposure, some companies are choosing to say less.

Stricter regulatory environments such as enhanced substantiation requirements and litigation risks are contributing to this shift. As explored in LegalClarity’s ESG risk analysis, companies are increasingly weighing the cost of disclosure against the risk of legal challenge.

At the same time, signs of retreat are emerging in financial markets, with some institutions quietly stepping back from high-profile climate commitments.

While greenwashing may reduce short-term risk, it introduces longer-term consequences: reduced transparency, weaker investor confidence, and less efficient capital allocation.

ESG Ratings: The Credibility Gap

Even when companies disclose extensively, another challenge persists - inconsistent with ESG ratings.

Research highlighted in Forward Law Review and broader ESG literature shows that correlations between major ESG rating providers remain significantly lower than those of credit rating agencies.

This inconsistency creates confusion for investors and raises a critical question:

If the metrics themselves are misaligned, how can “responsible business” be consistently defined?

The issue is prompting increasing calls particularly in Asia for more harmonized ESG frameworks and rating methodologies.

Walking the ESG Tightrope

In this evolving landscape, ESG communication requires precision, not volume.

Three principles emerge as essential:

•      Authenticity: Ensure alignment between claims and actual practices

•      Evidence: Support disclosures with verifiable data and audit trails

•      Materiality: Focus on what truly matters, avoiding overstatement

These themes are consistently reinforced across legal and advisory analyses, including the A&O Shearman ESG outlook.

Closing Insight

ESG integrity is no longer just a compliance requirement. It is a reputational asset and increasingly, a competitive differentiator.

“In 2026, the real challenge is not simply avoiding greenwashing or greenhushing.

It is navigating the narrow space between credibility, clarity, and confidence.”
