EU Locks In 90% Climate Target for 2040 — But Softens Corporate Supply-Chain Rules

The European Union has taken two significant steps in the same week — and they point in opposite directions. On one hand, EU member states gave final approval to a binding 2040 climate target requiring a 90% reduction in greenhouse gas emissions compared to 1990 levels. On the other, they approved a rollback of key supply-chain due diligence requirements that had obliged companies to identify and address environmental and human-rights risks across their operations. Together, these decisions define a new chapter in European climate and ESG policy: higher long-term ambition, lower short-term compliance pressure.

A Landmark 2040 Target — and What It Actually Demands

The 90% emissions reduction target for 2040 is not symbolic. It fills the gap between the EU’s existing 2030 goal — a 55% net reduction under the Fit for 55 package — and the bloc’s long-term objective of climate neutrality by 2050. Endorsed by the European Climate Law framework, this intermediate milestone sends a clear signal to investors, industries, and policymakers: decarbonization is a structural, irreversible trend, not a political phase.

For businesses operating in Europe, the implications are substantial. Energy-intensive sectors — steel, cement, chemicals, aviation — will face tightening benchmarks under the EU Emissions Trading System (ETS). Sustainable finance instruments, from green bonds to taxonomy-aligned investment products, will increasingly be calibrated against this 2040 trajectory. Companies that have already embedded science-based targets and ESG reporting into their strategy are better positioned; those that have delayed will find the runway shortening fast.

The target also carries geopolitical weight. China simultaneously announced a 17% carbon-intensity reduction target within its current five-year plan — a sign that major economies are aligning, however imperfectly, around decarbonization. For global supply chains and clean-tech demand, this convergence matters enormously.

Supply-Chain Due Diligence: A Step Back on Corporate Responsibility

The same week’s approval of a scaled-back Corporate Sustainability Due Diligence Directive (CS3D) tells a more complicated story. The original directive required large companies to conduct thorough due diligence on environmental damage and human-rights violations throughout their value chains — a cornerstone of the EU’s push toward genuine corporate responsibility and sustainable business practice.

The revised version reduces the scope and depth of those obligations, particularly for smaller companies in supply chains and for certain compliance timelines. Proponents argue this eases disproportionate burdens on mid-sized firms and improves competitiveness. Critics — including environmental NGOs and responsible investment advocates — warn it weakens accountability precisely where it is most needed: in upstream supply chains where environmental and social risks are concentrated.

From an ESG perspective, the rollback creates a paradox. Investors and asset managers who rely on supply-chain transparency to assess material risks will have less standardised data to work with. The circular economy agenda, which depends on traceability of materials and ethical sourcing, also loses a key regulatory lever. The EU is essentially asking companies to aim higher on climate outcomes while reducing the mechanisms designed to verify how they get there.

Global Context: COP30 Turbulence and the Finance Gap

These European developments land against a turbulent global backdrop. At COP30, negotiations were disrupted by a fire at the venue — a logistical crisis that compounded deeper structural difficulties. Efforts to finalise a UN-backed international carbon market continue to face serious design and financing challenges, highlighting that climate finance and carbon market governance remain the most stubborn bottlenecks in global climate action.

For European policymakers and sustainable finance professionals, the message is clear: domestic ambition must be matched by robust international frameworks. Without credible carbon pricing and supply-chain accountability at scale, the EU’s climate targets risk becoming isolated commitments in a fragmented global system.

Implications for Businesses and Citizens

• Long-term decarbonization planning is now non-negotiable for any company with significant European operations or market exposure.
• ESG reporting and green business strategy must account for the 2040 target when setting scope 1, 2, and 3 emissions pathways.
• Supply-chain due diligence, though partially relaxed in regulation, remains a reputational and investor-relations priority — voluntary standards will fill some of the gap left by the rollback.
• Citizens can expect continued climate-policy direction from Brussels, but should also scrutinise whether reduced corporate compliance requirements translate into real-world accountability gaps.

Key takeaway: The EU is doubling down on its climate destination while loosening some of the rules governing how companies get there. For the sustainability and ESG community, this week’s decisions are a reminder that policy ambition and policy coherence are not always the same thing — and that the distance between a target and a transformation still depends on the mechanisms built to bridge them.
