Environment policy: general principles and basic framework
Europe faces complex environmental issues, ranging from climate change and biodiversity loss to resource depletion and pollution. To address these challenges, the EU has put in place a large set of environmental policies that have moved environmental concerns to the forefront of the EU policy agenda. The four key principles of European environment policy are those of precaution, prevention, rectifying pollution at source and the ‘polluter pays’.
Legal basis
Articles 11 and 191 to 193 of the Treaty on the Functioning of the European Union (TFEU) establish the EU as the competent body for environment policy. Its areas of action include air and water pollution, waste management and climate change.
Origins and development
A. International declarations
In 1972, the first UN Conference on the Human Environment took place in Stockholm. It placed environmental issues at the forefront of international concerns and adopted principles for sound management of the environment, including the Stockholm Declaration and Action Plan for the Human Environment.
In 1992, the ‘Earth Summit’ was held in Rio de Janeiro. This conference led to the adoption of several influential declarations, such as Agenda 21, the Rio Declaration, the United Nations Framework Convention on Climate Change (UNFCCC) and the Convention on Biological Diversity.
B. European Treaties
At the Paris Summit in 1972, the Council of the European Communities declared the need for a Community environment policy flanking economic policies and called for an action programme to conserve and improve the environment and to combat pollution and nuisances.
In 1987, the Single European Act introduced a new ‘Environment Title’ (Title VII), which provided the first legal basis for a common environment policy. Its aims are to preserve the quality of the environment, protect human health and ensure rational use of natural resources. Subsequent treaty revisions strengthened the Community’s commitment to environmental protection and the role of Parliament in its development.
In 1993, the Treaty of Maastricht made the environment (Title XVI) an official EU policy area. It introduced the co-decision procedure and made qualified majority voting in the Council the general rule. Moreover, it urged Member States to assess their environmental impact and uphold the principle of sustainable growth.
In 1999, Article 3c of the Treaty of Amsterdam mandated the integration of environmental protection into all EU sectoral policies so as to promote sustainable development.
In 2007, the Treaty of Lisbon made climate change and sustainable development a priority. It also granted the EU legal personality to conclude international agreements.
General principles
EU environment policy is based on four principles:
- Precaution: if an action or policy has the potential to cause harm to the environment or public health, and there is persisting scientific uncertainty about its effects, this action should not be applied until further evidence is provided;
- Prevention: a tool aimed at preventing environmental damage, rather than reacting to it. This requires preventive measures to be taken to anticipate and avoid environmental damage;
- Rectifying pollution at source: if damage to the environment has already occurred, polluters are obliged to take the appropriate measures to remedy the damage at the point of origin;
- ‘Polluter pays’: if damage has occurred, the polluters are obliged to take the appropriate measures to remedy it and pay for the costs. This is implemented through the Environmental Liability Directive, which aims to prevent or otherwise remedy environmental damage to protected species or natural habitats, water and soil.
Basic framework
A. Environment Action Programmes
Since 1973, the Commission has issued multiannual Environment Action Programmes (EAPs) setting out forthcoming legislative proposals and goals for EU environment policy. In May 2022, the 8th EAP entered into force as the EU’s legally agreed upon common agenda for environment policy until the end of 2030. It builds on the environmental and climate objectives of the European Green Deal through six key priorities:
- Achieving the 2030 greenhouse gas emission reduction target of 55% (compared to 1990 levels) and climate neutrality by 2050;
- Enhancing adaptive capacity, strengthening resilience and reducing vulnerability to climate change;
- Advancing towards a regenerative growth model, decoupling economic growth from resource use and environmental degradation, and accelerating the transition to a circular economy;
- Pursuing a zero-pollution ambition, including for air, water and soil and protecting the health and well-being of Europeans;
- Protecting, preserving and restoring biodiversity, and enhancing natural capital (notably air, water, soil, forest, freshwater, wetland and marine ecosystems);
- Reducing environmental and climate pressures related to production and consumption (particularly in the areas of energy, industrial development, buildings and infrastructure, mobility and the food system).
B. Horizontal initiatives
1. Sustainable development
The EU introduced its first sustainable development strategy in 2001, thereby adding an environmental dimension to its Lisbon strategy. In response to the 2030 Agenda for Sustainable Development adopted by the UN in 2015, the Commission published a communication in 2016 entitled ‘Next steps for a sustainable European future – European action for sustainability’, outlining how to integrate the Sustainable Development Goals (SDGs) into EU policy priorities.
Sustainable development became a priority objective for the EU’s internal and external policies, and the EU is a leading global partner for the implementation of the SDGs.
2. Decarbonisation
The EU aims to be climate-neutral by 2050. This is at the heart of the European Green Deal, launched in 2019, which sets out a plan to transform Europe’s economy, energy, transport, and industries for a more sustainable future. The European Climate Law, adopted in 2021, translated this goal into law by setting an EU-wide legally binding target of climate neutrality or net-zero greenhouse gas (GHG) emissions by 2050. It aims to ensure that all EU policies support this goal and that all sectors of the economy and society equally contribute to achieve it. As an intermediary step, the EU has set as target for 2030 to reduce net GHG emissions by at least 55% compared to levels in 1990. The negotiations on the 2040 targets are ongoing. In 2023, the EU adopted the ‘Fit for 55’ package, a set of proposals that revised all the policy instruments that are relevant for achieving the 2030 climate target. In February 2025, the Clean Industrial Deal was presented as part of the broader strategy of the European Green Deal industrial plan. It aims to turn the EU into a world leader in the development of clean technologies and carbon emissions reduction, striving for climate neutrality by 2050 and turning decarbonisation into a driver of growth.
3. Biodiversity
In 2011, the EU adopted its biodiversity strategy to 2020, reflecting the commitments made within the UN Convention on Biological Diversity, the main international agreement on biodiversity, to which the EU is a party. The Commission presented its biodiversity strategy for 2030 in May 2020, as part of the European Green Deal. It is a comprehensive, ambitious and long-term plan to protect nature and reverse the deterioration of ecosystems. According to the Commission’s action tracking tool, 51 actions of the EU biodiversity strategy have been completed to date, 44 are in progress and 9 are delayed.
In June 2024, the co-legislators adopted the Nature Restoration Regulation (Regulation (EU) 2024/1991), which aims to restore at least 30% of the EU’s land and sea areas by 2030 and 90% of all ecosystems in need of restoration by 2050.
4. Food systems
In May 2020, within the framework of the European Green Deal, the Commission presented its Farm to Fork strategy, which aims to make food systems fair, healthy and environmentally friendly.
On 19 February 2025, the Commission presented a communication on a ‘Vision for Agriculture and Food’. The document pledges that the EU will continue working with key international organisations to reinforce the implementation of internationally agreed commitments and to increase their ambition to achieve global sustainable food systems in line with the Agenda 2030 and the SDGs.
5. Waste management
The Waste Framework Directive of 2008 defines key concepts such as waste, recycling and recovery, and sets basic principles requiring that waste be managed without endangering human health or the environment, and without causing nuisance or harm to nature and protected areas. New rules entered into force in October 2025 to prevent and reduce waste from food and textiles across the EU.
C. International environmental cooperation
The EU plays a key role in international environmental negotiations. It is a party to numerous global, regional or sub-regional multilateral environmental agreements on a wide range of issues, such as nature protection and biodiversity, climate change and transboundary air or water pollution. The EU helped shape several major international agreements adopted in 2015 at UN level, such as the 2030 Agenda for Sustainable Development (which includes the 17 global SDGs and their 169 associated targets), the Paris Agreement on climate change and the Sendai Framework for Disaster Risk Reduction. It also became a party to the Convention on International Trade in Endangered Species (CITES), underscoring its dedication to conserving biodiversity and curbing the illicit wildlife trade. Moreover, the EU is committed to the full and swift implementation of the Kunming-Montreal Global Biodiversity Framework of 2022, which aims to halt and reverse biodiversity loss by 2030.
D. Environmental impact assessment and public participation
Certain projects (private or public) that are likely to have significant effects on the environment, e.g. the construction of a motorway or an airport, are subject to an environmental impact assessment (EIA). Furthermore, a range of public plans and programmes (e.g. concerning land use, transport, energy, waste or agriculture) are subject to a similar process called a strategic environmental assessment (SEA). Both directives ensure that an environmental assessment takes place before the authorisation of any plans, programmes or projects.
In both cases, consultation with the public is a central aspect. This goes back to the 1998 Aarhus Convention, a multilateral environmental agreement to which the EU and all its Member States are parties. It guarantees three rights to the public: public participation in environmental decision-making, access to environmental information held by public authorities (e.g. on the state of the environment or of human health where affected by the former) and the right of access to justice where the other two rights have been disregarded. These rights have been enshrined in EU legislation through two major directives, namely 2003/4/EC and 2003/35/EC.
E. Implementation, enforcement and monitoring
The effectiveness of EU environmental policy is largely determined by its implementation at national, regional and local levels. Deficient application and enforcement remain an important issue. Monitoring is crucial – both of the state of the environment and of the level of implementation of EU environmental law.
In May 2024, the new Environmental Crime Directive came into force. It addresses activities that breach relevant legal obligations, such as wildlife crimes and deterioration of habitats, illegal shipment or dumping of waste, pollution crimes and illegal trading in dangerous substances.
The European Union Network for the Implementation and Enforcement of Environmental Law (IMPEL) is an international network of environmental authorities created to boost enforcement by providing a platform for policymakers, environmental inspectors and enforcement officers to exchange ideas and best practices.
In May 2016, the Commission launched the Environmental Implementation Review, a regular reporting tool to improve the implementation of EU environmental laws and policies.
In 1990, the European Environment Agency (EEA) was established in Copenhagen to support the development, implementation and evaluation of environment policy and to inform the general public on the matter. In 2025, it published its seventh report on the state and outlook of the European environment.
In terms of monitoring, the EU also runs the European Earth Observation Programme (Copernicus), which provides environmental observation satellite data. With regard to pollutants, the European Pollutant Release and Transfer Register (E-PRTR) provides key environmental data from more than 30 000 industrial facilities in the EU. Data from both programmes is open access.
Role of the European Parliament
Parliament has been playing a major role in shaping EU environmental policy since its creation in 1972. During its eighth term (2014-2019), it dealt with legislation deriving from the circular economy action plan (on waste, batteries, end-of-life vehicles, landfilling, etc.), climate change issues (ratification of the Paris Agreement, effort sharing, accounting for land use, land-use change and forestry in the EU’s climate change commitments, Emissions Trading System reform, etc.) and more.
During its ninth term (2019-2024), Parliament played a key role in discussing the proposals put forward by the Commission as part of the European Green Deal. In particular, Parliament contributed to shaping the European Climate Law, adopted in 2021, as well as the ‘Fit for 55’ package, adopted in 2023.
During its current tenth term (2024-2029), Parliament, and in particular its Committee on the Environment, Climate and Food Safety, is continuing its efforts towards making the Union more sustainable, climate-resilient and clean. In particular, Members are working towards the implementation and delivery of the Green Deal to complete a fair and equitable transition to a greener economy and cope with the consequences of climate change. Ensuring safer food for all Europeans is also high on the agenda, as are policies related to topics such as the circular economy, biodiversity, air, water and soil quality and the use of chemicals and pesticides.
