ETS Intensification and Industrial Decarbonization: Accelerating Transformation Amid Competitiveness Concerns

The EU Emissions Trading System (ETS) has tightened further in 2026, reinforcing its status as the bedrock of Europe’s climate policy. Carbon prices consistently hold above €100 per tonne of CO₂, reflecting sustained investor confidence in the EU’s stringent emission caps. Key advancements include:

• The continued phase-out of free allowances, particularly targeting sectors like steel, cement, and chemicals, is intensifying pressure on industrial emitters to decarbonize swiftly. This has catalyzed a wave of capital investments exemplified by ArcelorMittal’s €1.5 billion electrification project in France, a flagship initiative demonstrating how stable regulatory signals can drive transformative industrial shifts.
• However, energy price volatility and the accelerated removal of free allowances have amplified competitiveness concerns, especially within the chemical industry, prompting vigorous lobbying ahead of upcoming economic forums.
• The ETS’s dynamic, performance-based benchmarks remain aligned with credible net-zero pathways, ensuring that emission reductions are both ambitious and technologically grounded.

This phase underscores the EU’s dual challenge: fostering deep decarbonization while maintaining industrial competitiveness on the global stage.

CBAM Operationalization Broadens Carbon Pricing Reach; Aluminium Imports Face New Cost Pressures

The Carbon Border Adjustment Mechanism (CBAM) has reached full operational status in 2026, marking a pivotal extension of EU carbon pricing beyond its borders:

• The European Commission has published detailed compliance and reporting guidelines, simplifying importers’ obligations in carbon-intensive sectors such as steel, cement, aluminium, and fertilizers. This clarity aids enforcement and reduces administrative friction.
• A new report highlights that aluminium extrusion imports are now subject to up to €230 per tonne in additional CBAM-related carbon costs, potentially reshaping supply chains and incentivizing decarbonization efforts outside the EU.
• The mechanism’s strict offset rules have been tightened, now accepting only highly verified carbon offsets to prevent greenwashing and ensure environmental integrity.
• For non-EU exporters, compliance burdens have intensified. Serbia’s steel and cement industries provide a salient example, having to adapt rapidly to new emissions monitoring, reporting, and verification standards necessary to obtain CBAM certificates. This introduces operational and financial challenges that test exporters’ market viability.

Collectively, these developments amplify the EU’s extraterritorial climate influence, compelling global suppliers to internalize carbon costs or risk exclusion from the EU market.

UK Regulatory Alignment and ISSB Adoption Advance Transnational ESG Standardization

Efforts to harmonize carbon pricing and sustainability reporting across Europe and beyond have gained momentum:

• The United Kingdom officially announced the launch of its Sustainability Reporting Standard (SRS), set to align closely with EU frameworks and international standards starting January 2027. This move reduces trans-European trade frictions and promotes regulatory coherence within the continent’s largest trading bloc.
• Beyond Europe, Australia’s phased adoption of the International Sustainability Standards Board (ISSB) IFRS S1 and S2 standards signals growing global momentum toward unified ESG disclosure regimes. This multipolar alignment facilitates comparability but also introduces complexity given the coexistence of EU-specific rules.
• The UK’s Financial Conduct Authority (FCA) endorsement of ISSB standards underscores a strategic convergence with EU sustainability disclosure ambitions, reinforcing investor confidence through greater data harmonization.

These developments reflect a broader trend toward international ESG standard convergence, though the coexistence of overlapping frameworks continues to generate debate on clarity and compliance burdens.

Heightened Supervisory Activism and Enhanced Disclosure Regimes: CSRD, ESRS, and CSDDD Enforcement Tighten

2026 marks a watershed year for sustainability disclosure enforcement, with supervisors escalating scrutiny to ensure robust, comparable, and reliable ESG reporting:

• The Corporate Sustainability Reporting Directive (CSRD) and European Sustainability Reporting Standards (ESRS), together with the Corporate Sustainability Due Diligence Directive (CSDDD), approach full enforcement. Companies must now deliver comprehensive, double-materiality disclosures extending across entire value chains.
• Regulatory bodies such as the European Central Bank (ECB) and the European Securities and Markets Authority (ESMA) have intensified enforcement actions, emphasizing data verifiability and penalizing superficial “greenwashing” practices.
• A recent IPE report calls for stronger enforcement mechanisms and clearer supervisory expectations, highlighting a shift from box-ticking compliance toward substantive sustainability governance.
• To support companies, the Commission released a practical “Checklist for ESG Compliance in Due Diligence”, designed to guide firms through the complexities of CSDDD requirements.
• Complementary digital tools like Hashgraph’s TrackTrace platform and the Compliance Scorecard v10 leverage blockchain and AI to provide audit-ready emissions data, supply chain transparency, and streamlined regulatory reporting.
• Board-level risk management is becoming increasingly focused on climate and environmental risks, prompted by supervisory expectations and investor demands.

This enhanced supervisory activism is significantly elevating the rigor and credibility of corporate sustainability disclosures across Europe.

The EU Omnibus I Directive: Balancing Ambition and Practicality Amid Legal and Political Debates

In response to industry and SME concerns, the EU published the Omnibus I Directive in 2026, introducing targeted reforms designed to ease certain reporting and liability burdens:

• The Directive caps penalties for non-compliance at 3% of net worldwide turnover, providing predictability and limiting financial risk exposure.
• Reporting requirements and due diligence obligations for smaller enterprises have been relaxed, aiming to reduce administrative overhead while maintaining core transparency standards.
• These adjustments have sparked debate among stakeholders — some argue the easing risks diluting climate ambition, while others view it as a pragmatic step toward wider and more effective implementation.
• The Directive also reforms civil liability provisions related to sustainability disclosures, clarifying companies’ responsibilities and legal accountability.

The Omnibus package reflects the EU’s ongoing effort to balance rigorous climate governance with economic feasibility and stakeholder acceptance.
