In 2025, sustainability has crossed a critical threshold: from ambition to accountability. While the past decade saw a proliferation of ESG claims—often unverified and inconsistently reported—the regulatory landscape has begun to close the gap between narrative and performance. What was once a landscape of voluntary principles is rapidly being replaced with enforceable, standardized, and highly scrutinized disclosure requirements.

This shift marks the beginning of the compliance-driven era of ESG, where businesses are expected not only to say what they do—but to prove it, publicly, quantitatively, and comparably.

 

The rise in ESG enforcement is not merely a policy trend. It reflects growing concerns among regulators, investors, and consumers that greenwashing—the practice of overstating or misrepresenting environmental claims—is distorting markets, undermining trust, and delaying climate action.

 

In 2025, ESG no longer operates in a reputational silo. It is now a regulatory obligation, subject to legal consequences, investor audits, and capital allocation decisions.

The Regulatory Landscape: From Frameworks to Mandates

Globally, regulatory bodies have moved beyond aspirational principles to hard law. Companies operating in or exporting to the EU, UK, US, and other advanced economies must now adhere to precise disclosure rules, labeling standards, and product substantiation requirements.

 

  1. EU Green Claims Directive (2025–2028 Rollout)

This legislation sets strict parameters around how companies communicate environmental benefits in marketing. Key components include:

  • Mandatory substantiation of green claims using recognized scientific evidence.
  • Standardized labeling requirements to avoid misleading environmental certifications.
  • Ban on carbon neutrality claims based solely on offsetting, unless lifecycle data is disclosed.

The directive targets the systemic misuse of vague terms like “eco-friendly,” “carbon neutral,” and “sustainable,” unless companies can demonstrate performance aligned with those labels.

 

  1. Corporate Sustainability Reporting Directive (CSRD)

Now in effect for large EU-listed companies, the CSRD requires disclosures under the European Sustainability Reporting Standards (ESRS). It mandates:

  • Double materiality reporting (financial + impact).
  • Sector-specific performance indicators (KPIs) tied to climate, biodiversity, and workforce.
  • Assurance requirements similar to financial auditing.
  • Digital tagging of disclosures for machine-readability and comparability.

Companies must also disclose forward-looking transition plans, science-based targets, and their progress toward Net Zero—including scope 1, 2, and 3 emissions.

 

  1. Global Alignment: IFRS, ISSB, and Beyond

Outside Europe, standard-setting bodies such as the International Sustainability Standards Board (ISSB) have launched baseline climate-related disclosure frameworks now being adopted by over 50 jurisdictions.

Many of these align with TCFD principles and include:

  • Governance structure around sustainability.
  • Climate risk and opportunity analysis.
  • GHG emissions inventory, including supply chain emissions.
  • Metrics and targets for climate adaptation and mitigation.

 

In parallel, SEC (US) and FRC (UK) are tightening ESG-related financial disclosures, focusing on investor protection, data integrity, and anti-fraud measures.

Implications for Businesses: From Reporting to Accountability

As regulations grow in scope and enforcement strength, companies face a new set of expectations. It is no longer sufficient to publish glossy sustainability reports or rely on carbon offset programs as the cornerstone of climate strategies.

What’s required in 2025 is evidence-based, audit-grade sustainability reporting that is:

  • Comparable: Built on standardized KPIs aligned with global benchmarks.
  • Verifiable: Supported by third-party assurance and traceable data.
  • Consistent: Integrated across financial, operational, and governance disclosures.
  • Forward-looking: Showing not just historical data, but future transition planning.

 

Businesses that fail to meet these requirements face reputational, legal, and capital market risks, including:

  • Fines and litigation for false or misleading claims.
  • ESG rating downgrades affecting investor perception.
  • Exclusion from sustainable finance instruments (e.g., green bonds, ESG funds).
  • Reputational backlash from activist shareholders and watchdogs.

What Is No Longer Acceptable in 2025

Regulatory tightening in 2025 signals a decisive rejection of outdated ESG practices. The following are increasingly unacceptable under current and emerging regulations:

Obsolete Practice

Why It No Longer Works

Offset-based “Net Zero” claims without lifecycle transparency

Disregards emissions hierarchy and fails to show operational decarbonization.

Vague marketing terms (“eco,” “green,” “carbon-friendly”)

Banned unless supported by credible evidence under laws like the Green Claims Directive.

Unverified ESG metrics

Must now be traceable, auditable, and aligned with approved standards.

CSR-style reports lacking structured frameworks

Regulatory disclosures require ESRS/ISSB alignment and digital tagging.

Building Internal Capacity for ESG Compliance

Responding to this regulatory shift requires structural change—not just cosmetic fixes. Businesses must equip themselves with the tools, processes, and governance models to produce data-driven, risk-adjusted ESG disclosures.

Key internal priorities include:

  • Data Infrastructure

Integrate sustainability data systems with financial and operational platforms. Use ESG software with audit trails and workflow tracking.

  • Governance Integration

Assign board-level ESG accountability and align executive KPIs with verified sustainability outcomes.

  • Internal Controls & Assurance

Apply internal audit protocols to non-financial data. Engage third-party verifiers to review ESG disclosures pre-publication.

  • Policy and Claim Vetting

Subject all marketing claims related to sustainability to legal and technical review. Maintain evidence dossiers for each environmental statement.

  • Supply Chain ESG Risk Mapping

Ensure Scope 3 emissions, human rights, and biodiversity risks are identified, measured, and disclosed across the supplier ecosystem.

Role of Third-Party Experts in Ensuring ESG Credibility

Given the complexity and evolving nature of ESG regulation, many companies are turning to external advisors for technical support, especially in:

  • Interpreting jurisdiction-specific disclosure requirements.
  • Designing aligned reporting templates and dashboards.
  • Conducting materiality assessments that meet regulatory thresholds.
  • Preparing ESG statements for external assurance and investor-grade review.

 

Third-party expertise also helps ensure that internal teams aren’t operating in isolation, especially as ESG requirements increasingly intersect with tax, legal, procurement, HR, and finance departments.

The IFRSLAB Perspective

At IFRSLAB, we support companies in moving beyond box-ticking compliance toward credible, strategic ESG reporting. As sustainability becomes legally binding and reputationally critical, our services ensure clients:

  • Align with CSRD, ISSB, and GRI standards.
  • Avoid greenwashing by validating every claim against measurable performance.
  • Produce disclosures that stand up to investor scrutiny and regulatory audits.

 

The era of unchecked ESG storytelling is over. The companies that lead in 2025 will be those that report with integrity, operate with transparency, and commit to sustainability through measurable action—not marketing gloss.

 

We help you become that company.
