Environmental principles inform legal frameworks that relate to environmental protection or sustainable development. Article 191(2) of TFEU sets out four main environmental principles that must guide policy within the scope of EU law (CBP8132). These have been influential in formulating a range of EU directives and regulatory actions, and constitute the main focus of this note. The principles listed are:

  • The precautionary principle, which allows regulatory action to be taken even if a risk has not been established with full certainty.
  • The prevention principle, which aims to prevent environmental damage; such as to protected species or to natural habitats, water and soil; rather than to react to it.
  • The rectification at source principle, which seeks to prevent pollution at its source rather than remedy its effects.
  • The polluter pays principle, which requires polluters to bear the financial cost of their actions.

 Key points in this POSTnote include:

  • EU environmental law and policy is based on four core environmental principles contained in Article 191(2) of the Treaty on the Functioning of the European Union (TFEU): the precautionary, prevention, rectification at source, and polluter pays principles.
  • The principles do not create direct legal rights but have been used by the courts to interpret and apply EU environmental law.
  • The precautionary principle is applied to manage risk in cases of scientific uncertainty.
  • The polluter pays principle is used to allocate responsibility for pollution costs, although attributing these costs can be complex.
