EU Environmental Law
Legal Basis and Principles
EU environmental law derives its authority from Articles 191-193 TFEU. Article 191(1) establishes objectives: preserving, protecting, and improving environmental quality; protecting human health; ensuring prudent and rational utilisation of natural resources; and promoting international measures to combat climate change. Article 191(2) codifies the precautionary principle, the principle of preventive action, the principle of rectification at source, and the polluter pays principle. Article 11 TFEU requires integration of environmental protection into all EU policies across agriculture, transport, energy, and economic governance. The principle of subsidiarity limits EU action to matters where objectives cannot be sufficiently achieved by member states alone. The CJEU has played a significant role in developing environmental law, interpreting directives broadly to ensure their effectiveness and enforcing member state compliance through infringement proceedings.
Air Quality Legislation
The Ambient Air Quality Directive 2008/50/EC establishes binding limit values for PM10, PM2.5, NO2, SO2, and ozone. Member states must designate air quality zones and prepare plans where limits are exceeded. The CJEU has held that individuals may rely on limit values in legal proceedings. The Industrial Emissions Directive 2010/75/EU (IED) requires permits for approximately 50,000 industrial installations based on Best Available Techniques (BAT) through BAT reference documents (BREFs).
Water Legislation
The Water Framework Directive 2000/60/EC (WFD) adopts a river basin management approach requiring member states to prepare management plans to achieve good status for all water bodies — good ecological and chemical status for surface waters, good quantitative and chemical status for groundwater. The WFD introduces full cost recovery for water services and a strict non-deterioration obligation. Complementary instruments include the Groundwater Directive 2006/118/EC, the Bathing Water Directive 2006/7/EC, the Urban Waste Water Treatment Directive 91/271/EEC, and the Nitrates Directive 91/676/EEC.
Nature and Biodiversity Legislation
The Birds Directive 2009/147/EC and the Habitats Directive 92/43/EEC form the cornerstone of EU nature law, establishing the Natura 2000 network — the world’s largest coordinated protected area network, covering approximately 18% of EU land. The Birds Directive requires Special Protection Areas (SPAs) for listed bird species. The Habitats Directive requires Special Areas of Conservation (SACs) for listed habitats and species, a strict protection regime for Annex IV species, and an appropriate assessment under Article 6(3) for plans or projects likely to significantly affect Natura 2000 sites, with Article 6(4) providing a derogation for imperative reasons of overriding public interest requiring compensatory measures.
Waste Legislation
The Waste Framework Directive 2008/98/EC defines waste as any substance or object the holder discards or intends or is required to discard, and establishes the waste hierarchy: prevention, preparing for re-use, recycling, other recovery, and disposal. It introduces end-of-waste and by-product criteria and extended producer responsibility obligations requiring member states to establish separate collection for paper, metal, plastic, glass, and bio-waste. The Landfill Directive 1999/31/EC sets strict operational requirements and progressive reduction of biodegradable municipal waste sent to landfill. The Packaging and Packaging Waste Directive 94/62/EC sets recovery and recycling targets. The Circular Economy Package (2018) amended the directives with higher targets including 65% recycling of municipal waste and a maximum 10% landfill rate by 2035.
Climate Change Legislation
The EU ETS Directive 2003/87/EC establishes the world’s largest carbon market, applying a cap-and-trade system to power generation, industry, aviation, and maritime transport. The ‘Fit for 55’ package (2023) revised the EU ETS to accelerate cap reduction, phase out free allowances for CBAM-covered sectors, and extend trading to maritime and a new ETS for buildings and road transport, aiming for a 55% emissions reduction by 2030. The Effort Sharing Regulation 2018/842/EU sets binding national targets for non-ETS sectors. The LULUCF Regulation 2018/841/EU requires a no-debit commitment from land use.
The Carbon Border Adjustment Mechanism (CBAM) Regulation 2023/956/EU requires importers of cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen to purchase certificates corresponding to the EU ETS carbon price, adjusted for the carbon price paid in the country of origin, preventing carbon leakage and incentivising cleaner production abroad.
Environmental Liability
The Environmental Liability Directive 2004/35/EC (ELD) establishes strict liability for environmental damage — to protected species, habitats, water, and land — caused by listed occupational activities, requiring operators to take preventive and remedial measures to restore the environment to baseline condition. Personal injury and property damage remain governed by national tort law.
