Green Deal in Action: EU’s Environmental Law Evolution in 2025

Introduction: Environmental Law at the Core of EU Policy

The European Green Deal, unveiled in 2019, set an ambitious goal: making the European Union climate-neutral by 2050. But as of 2025, the Green Deal is no longer just a vision—it’s driving profound changes across EU law. From stricter industrial emissions to nature restoration and border carbon taxes, the EU is placing environmental sustainability at the heart of its legal and economic systems.

This article explores the latest updates in EU environmental legislation, focusing on new laws that impact industries, member states, and international trade.

1. The Revised Industrial Emissions Directive (IED)

The Industrial Emissions Directive has long been a cornerstone of EU environmental law. But recent reforms have made it tougher and more dynamic.

The revised IED now:

• Expands coverage to new sectors, including intensive livestock farming and battery production,

• Introduces sector-specific emission benchmarks, reviewed more frequently,

• Mandates “polluter pays” accountability, making environmental harm more financially consequential for companies,

• Integrates climate, water, and air objectives more directly.

Operators must also prepare Transformation Plans outlining how they will decarbonize by 2030–2040, signaling a shift from short-term compliance to long-term sustainability planning.

2. The Nature Restoration Law: Healing Europe’s Ecosystems

One of the most ambitious green laws ever adopted, the Nature Restoration Law sets binding EU-wide targets to restore at least 20% of the EU’s degraded land and sea areas by 2030, and all ecosystems in need by 2050.

Member States must submit detailed Restoration Plans, specifying:

• Ecosystems to be restored (forests, rivers, wetlands, urban green spaces),

• Measures for biodiversity recovery (e.g., pollinator habitats, soil health),

• Timelines, monitoring methods, and local stakeholder involvement.

This law not only boosts climate resilience and food security but also makes restoration a legal obligation, rather than a voluntary ambition.

Despite initial political resistance—especially from agricultural lobbies—the legislation passed with amendments to safeguard farmers' roles and rural development.

3. Carbon Border Adjustment Mechanism (CBAM): Greening Trade

Launched in transitional form in 2023 and advancing further in 2025, the CBAM is Europe’s tool for ensuring that imported goods meet EU climate standards. It applies to carbon-intensive products such as:

• Steel and iron,

• Cement and aluminum,

• Fertilizers and electricity.

Importers must now report embedded emissions in these products. From 2026, they will need to purchase CBAM certificates reflecting the carbon cost.

The goal is to prevent “carbon leakage” (when production moves to countries with looser climate rules) and to incentivize greener production methods globally.

This law positions the EU as a global leader in sustainable trade policy, though it is already facing WTO scrutiny and political pushback from non-EU exporters.

4. Sustainability Reporting and Corporate Responsibility

In parallel, the EU is implementing the Corporate Sustainability Reporting Directive (CSRD), which came into effect in 2024. Large companies (and soon SMEs) must now report on:

• Greenhouse gas emissions,

• Pollution and circular economy practices,

• Biodiversity impact,

• Climate risk strategies.

These reports must follow the European Sustainability Reporting Standards (ESRS) and be externally audited. The objective is to align corporate disclosure with environmental goals and investor demands.

Furthermore, the proposed Corporate Sustainability Due Diligence Directive (CSDDD) will require companies to prevent and mitigate adverse environmental impacts across global supply chains.

5. Legal Enforcement and Litigation Trends

With stronger laws come stronger enforcement. The European Commission, Member States, and even private citizens are becoming more active in:

• Launching infringement procedures against non-compliant states,

• Filing environmental complaints to EU institutions,

• Pursuing climate litigation in EU and national courts.

In several recent cases, courts have ruled that governments must take stronger climate action to meet EU and international obligations—showing how environmental law is becoming a tool for accountability.

Conclusion: Toward a Legally Enforced Green Transition

The EU’s environmental law in 2025 is no longer just about preventing pollution; it’s about transforming economic and social systems. From mandatory ecosystem restoration to carbon-adjusted trade, the Green Deal’s legislative framework is reshaping everything from agriculture to finance.

As the climate crisis intensifies, the EU model may serve as both a benchmark and a challenge to other regions. It reflects a growing belief that environmental sustainability is not just ethical or political—but legal.

For legal professionals, businesses, and policymakers alike, understanding and engaging with this evolving framework is no longer optional—it’s essential.
