EU’s 90% Emissions Target and ESG Rollback: What Businesses Need to Know

The European Union sent two powerful — and seemingly contradictory — signals to the business world this week. On one hand, EU member states gave final approval to a landmark 2040 climate target requiring a 90% reduction in greenhouse gas emissions compared to 1990 levels. On the other, the bloc finalized a significant rollback of its corporate due-diligence rules, easing the compliance burden on companies operating across global supply chains. Together, these moves are reshaping the ESG landscape for businesses, investors, and policymakers across Europe and beyond.

A 90% Climate Target: Ambition Locked In, Complexity Ahead

The approval of the EU’s 2040 climate target is arguably the most consequential sustainability policy decision in Europe in recent years. By committing to a 90% net reduction in greenhouse gas emissions by 2040 — a stepping stone between the current 55% target for 2030 and full climate neutrality by 2050 — the EU is sending a long-term signal that affects virtually every sector of the economy.

For businesses, this is not an abstract political milestone. It directly influences long-term investment planning, industrial strategy, and energy transition timelines. Companies in energy-intensive sectors — steel, cement, chemicals, transport — now face a clearer (and steeper) regulatory trajectory. Sustainable finance markets are also affected: green bonds, transition finance instruments, and ESG-linked lending will increasingly be benchmarked against this more demanding decarbonization path.

There is, however, a notable gap in ambition. EU draft proposals reportedly dropped an emissions label for steel from the upcoming ‘Made in Europe’ industrial law — a move that weakens a key policy signal for green steel procurement and investment in low-carbon materials. For circular economy advocates and industrial decarbonization efforts, this omission is a missed opportunity to align procurement standards with climate goals.

ESG Due Diligence Rolled Back: A Step Backward for Corporate Responsibility?

Simultaneously, the EU finalized changes that ease parts of the Corporate Sustainability Due Diligence Directive (CSDDD), reducing the obligations on companies to identify and address environmental and human rights risks in their supply chains. The rollback came after sustained pressure from business lobbies and several member state governments concerned about administrative burden and competitiveness.

The implications for ESG compliance are significant. Multinationals operating in Europe — particularly those with complex global sourcing networks — had been preparing for stricter due-diligence requirements. The easing of these rules may reduce short-term legal risk and compliance costs, but it also raises questions about the credibility of Europe’s corporate responsibility framework.

Critics argue that weakening supply chain accountability contradicts the spirit of the Green Deal and undermines sustainable finance standards that rely on robust non-financial disclosure. Investors focused on ESG metrics will need to reassess what the revised rules mean for how companies report on social and environmental risks — and whether voluntary commitments will fill the gap left by regulation.

Hydrogen Breakthroughs Add a Bright Spot to the Industrial Transition

Amid the regulatory turbulence, innovation is offering reasons for optimism. Researchers have reported a breakthrough in hydrogen production using a perovskite-based catalyst, potentially lowering both the cost and temperature requirements for clean hydrogen generation. Separately, emerging evidence from Canada points to naturally occurring underground hydrogen deposits as a potential continuous source of low-carbon fuel — a development with implications for energy security and industrial feedstock supply.

These advances matter for the broader green business ecosystem. Clean hydrogen is central to decarbonizing hard-to-abate sectors like steel, shipping, and heavy industry. If these technologies scale, they could accelerate the industrial transition that Europe’s 2040 target demands — and open new opportunities for sustainable finance instruments targeting hydrogen infrastructure.

What This Means for Businesses and Investors

The week’s developments highlight a defining tension in EU sustainability policy: tightening climate ambition alongside selective regulatory simplification. For companies navigating this environment, the key implications are:

• Long-term decarbonization planning is non-negotiable. The 2040 target is now law. Capital allocation, R&D investment, and supply chain restructuring must reflect a 90% emissions reduction horizon.
• ESG compliance frameworks are in flux. The CSDDD rollback creates short-term relief but long-term uncertainty. Companies should maintain robust voluntary standards to satisfy investor expectations and future regulatory tightening.
• Green materials and hydrogen are strategic priorities. The omission of a steel emissions label and the hydrogen breakthroughs both signal that industrial decarbonization will be a contested, fast-moving space requiring proactive positioning.
• Sustainable finance will need to adapt. Lenders and asset managers benchmarking against EU climate policy will need to update transition finance frameworks to reflect the new 2040 trajectory.

Key takeaway: Europe is simultaneously raising the climate bar and lowering some compliance hurdles — a combination that rewards businesses with genuine long-term sustainability strategies while creating ambiguity for those relying on regulation alone to drive ESG performance. The companies best positioned for this decade will be those that treat the 2040 target not as a distant deadline, but as a present-day business reality.
