The final quarter of 2025 marked a decisive turning point for ESG regulation. After several years of rapid regulatory expansion, policymakers across major jurisdictions began to recalibrate – shifting the focus from volume and scope to simplification, integrity, and implementation.
While Europe remained the epicenter of ESG rulemaking, this recalibration is global in nature, with far-reaching implications for multinational companies navigating complex regulatory environments, global supply chains, and evolving investor expectations.
The insights in this article are drawn from Datamaran’s comprehensive Quarterly Policy Brief, which is provided to clients every three months to help them stay abreast of important global regulatory developments, alongside our AI-powered regulation monitoring solution.
Europe Moves from Rulemaking to Refinement
In the European Union, Q4 delivered long-awaited clarity. Agreement on the Omnibus I package confirmed a significant simplification of the Corporate Sustainability Reporting Directive (CSRD) and the Corporate Sustainability Due Diligence Directive (CSDDD). Higher application thresholds, streamlined requirements, and a more risk-based approach to due diligence signal a clear intent: sustainability regulation should be ambitious, but also proportionate and workable.
This simplification agenda was reinforced by the delivery of simplified ESRS by EFRAG, which reduced mandatory data points by more than 60% and removed all voluntary disclosures. Together, these changes materially lower reporting burdens while sharpening the focus on decision-useful sustainability information.
Importantly, this shift extended well beyond reporting. As detailed in our Quarterly Policy Brief in Q4, the European Commission launched multiple simplification packages aimed at cutting administrative burden across environmental policy, financial services, digital regulation, healthcare, and the automotive sector. The decision to defer non-essential Level 2 technical standards until 2027 further underscored a broader shift: the EU is prioritizing regulatory coherence and competitiveness alongside sustainability objectives.
For companies, this creates both relief and responsibility. While compliance obligations are narrowing, expectations around governance, implementation quality, and strategic alignment remain high – particularly as Member States move toward national transposition in 2026.
A Global Recalibration Takes Shape
Our Q4 2025 Quarterly Policy Brief tracked how similar dynamics emerged outside the EU. The UK government unveiled a Corporate Reporting Modernization Package, streamlining corporate disclosures and signaling a broader review of the reporting framework in 2026. New Zealand adjusted its climate reporting regime by raising thresholds and moderating director liability, while Canada reintroduced a revised Climate-Aligned Finance Act, balancing ambition with flexibility.
The United States continued to move in a different regulatory direction, with federal banking regulators rescinding climate-related financial risk guidance. However, this did not remove expectations entirely. Investors, global regulators, and cross-border frameworks continue to drive demand for credible climate governance and disclosure, particularly for companies operating internationally.
Together, these developments point to a growing international consensus: ESG regulation must support long-term competitiveness and financial stability, rather than overwhelm organizations with reporting requirements that many may find impractical.
Carbon Markets Scale and Integrity Takes Center Stage
As reflected in our ongoing regulatory monitoring, while reporting requirements were simplified, carbon market regulation continued to accelerate. In the EU, implementing rules under the Carbon Removal Certification Framework strengthened certification, verification, and registry requirements, while the Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase and expanded its reach across value chains.
Beyond Europe, jurisdictions including Türkiye, Indonesia, the Philippines, Singapore, Australia, and Spain have advanced emissions trading systems, carbon credit frameworks, and carbon removal strategies. At the global level, ICMA introduced a new Climate Transition Bond label, reflecting rising demand for credible transition finance in hard-to-abate sectors.
The direction of travel is clear: carbon markets are expanding, and scrutiny is intensifying. Measurement, reporting, verification, and traceability are no longer optional; they are becoming foundational to participation, financing, and maintaining credible sustainability claims.
Anti-Greenwashing Rules Tighten Across Markets
Q4 2025 also saw regulators sharpen their focus on ESG integrity. The UK brought ESG ratings providers under Financial Conduct Authority oversight and introduced a national sustainability assurance standard. Singapore issued new anti-greenwashing guidance, while the EU proposed a major overhaul of the Sustainable Finance Disclosure Regulation (SFDR), replacing Articles 8 and 9 with a clearer three-tier product classification system and stricter marketing controls.
Across jurisdictions, the message is consistent: sustainability claims must be substantiated, verifiable, and aligned with recognized standards. For businesses, this raises the stakes around internal controls, documentation, and cross-functional coordination between sustainability, legal, risk, and communications teams.
Nature and Biodiversity Enter the Regulatory Mainstream
Finally, Q4 2025 confirmed that nature and biodiversity are moving from the margins to the core of ESG regulation. The ISSB’s decision to advance work on nature-related disclosures, building directly on the TNFD framework, signals likely global convergence beginning in 2026. Complementary guidance from TNFD and the release of the first ISO biodiversity standard further reinforce this shift.
Alongside mandatory frameworks such as the EU Deforestation Regulation, these developments suggest that nature-related risk and dependency analysis will soon become a mainstream regulatory and investor expectation.
What This Means for Businesses in 2026
Drawing on insights from our Quarterly Policy Briefs and continuous monitoring, we’ve seen a marked transition to a more mature phase of ESG regulation, one focused less on expansion and more on quality, integrity, and execution. For businesses, success now depends on the ability to:
- Continuously track regulatory change across jurisdictions
- Efficiently assess relevance and potential impact
- Coordinate responses across sustainability, legal, finance, and risk teams
- Act early on emerging requirements, not only those already in force
