EU Green Deal at a Crossroads: Simplification, the 2040 Climate Target, and What Comes Next

The EU Green Deal was always going to be a marathon, not a sprint. After years of headline-grabbing pledges and a flood of legislative proposals, Europe’s landmark climate and sustainability framework has entered a more demanding phase: turning ambition into workable law. In 2025, two forces are pulling at the Green Deal simultaneously — a drive to simplify rules that businesses say have become unmanageable, and mounting scientific pressure to lock in stronger emissions targets for 2040. How the EU navigates this tension will define the credibility of its climate policy for the decade ahead.

From Legislation to Implementation: Where the Green Deal Stands

The scale of the Green Deal’s legislative programme is striking. By January 2025, the European Commission had proposed 168 initiatives, of which 98 had been adopted, 37 were still under negotiation, and 28 more had been announced. That pipeline represents one of the most ambitious regulatory overhauls in EU history — covering everything from carbon markets and land use to corporate sustainability reporting and supply chain due diligence.

Yet ambition has a cost. The sheer volume and complexity of overlapping frameworks — the Corporate Sustainability Reporting Directive (CSRD), the EU Taxonomy, the European Sustainability Reporting Standards (ESRS), the Sustainable Finance Disclosure Regulation (SFDR), and the Carbon Border Adjustment Mechanism (CBAM) — triggered a wave of criticism from businesses, trade associations, and several member states. The complaint was not that the goals were wrong, but that the compliance burden had become disproportionate, particularly for mid-sized companies with limited legal and reporting resources.

The Commission’s response came in February 2025 with the launch of a sustainability Omnibus — a package designed to streamline and consolidate these rules without, at least in theory, weakening their environmental objectives. Whether the simplification exercise will preserve the substance of environmental regulation or quietly dilute it remains the central debate in Brussels.

The 2040 Target and the Science Behind It

While the regulatory architecture is being rationalised, the scientific and political pressure on long-term climate targets is intensifying. At the end of 2025, the EU reached a provisional agreement on a 2040 climate target, a crucial stepping stone between the current 2030 goal of at least 55% emissions reduction and the legally binding objective of climate neutrality by 2050.

New research published in Nature Communications adds weight to the case for ambition: the analysis concludes that an 86% reduction in greenhouse gas emissions by 2040 — compared to 1990 levels — would be consistent with achieving EU climate neutrality by 2050. That figure sits above the Commission’s own indicative proposal of around 90% net, but the research underlines that the margin for delay is narrow. Every year of slower action increases the technological and economic effort required in the 2040s.

Carbon pricing remains a cornerstone of the transition. The Carbon Border Adjustment Mechanism is scheduled to become fully operational in 2026, requiring importers of carbon-intensive goods — steel, cement, aluminium, fertilisers, and electricity — to pay a carbon price equivalent to what EU producers face under the Emissions Trading System. CBAM extends the reach of EU climate policy into global trade, raising both competitiveness questions and diplomatic sensitivities with major trading partners.

Implications: Balancing Ambition with Workability

The convergence of simplification and target-setting creates a genuine dilemma for European policymakers. Streamlining sustainability reporting rules could reduce the burden on companies and improve compliance rates — but if the process weakens disclosure requirements or narrows the scope of due diligence obligations, it risks undermining the transparency that investors, civil society, and trading partners increasingly rely on.

Several implications stand out for different stakeholders:

• Businesses and investors need clarity on which reporting obligations will change and when, as the Omnibus moves through the legislative process in 2025 and 2026.
• Industrial sectors facing CBAM — both EU producers and third-country exporters — must prepare for full operationalisation in 2026, including the administrative systems required to calculate and report embedded carbon.
• Policymakers at national and EU level face the task of translating the provisional 2040 target into binding sectoral pathways, particularly for hard-to-abate industries such as steel, chemicals, and heavy transport.
• Civil society and researchers will play a watchdog role, monitoring whether simplification preserves or erodes the Green Deal’s environmental integrity.

The broader global context matters too. As the EU refines its climate policy framework, other major economies — the United States, China, and emerging markets — are watching how Europe balances competitiveness concerns with regulatory ambition. The Green Deal’s credibility as a model for sustainable industrial policy depends on demonstrating that the two are not mutually exclusive.

Key takeaway: The EU Green Deal is not retreating — it is being stress-tested. The sustainability Omnibus and the 2040 climate target are not contradictions; they are the natural friction of turning a vision into durable law. The outcome of this phase will determine whether Europe’s environmental regulation remains a global benchmark or becomes a cautionary tale about overreach. Citizens, businesses, and decision-makers alike have every reason to follow the next 24 months closely.
