How to Enforce the Polluter-Pays Principle

The polluter-pays principle (PPP) requires those who produce pollution to bear the costs of managing it to prevent damage to human health and the environment. While established in the European Union and OECD, it is not yet a customary international norm due to ambiguities in defining 'the polluter' and varying national implementations. In climate change law, the PPP informs debates on loss and damage and is indirectly present in the Paris Agreement through nationally determined contributions and climate finance. The document suggests that combining the PPP with the principle of common but differentiated responsibilities (CBDR) could help the Global North absorb costs for environmental harms caused in the Global South.

• The polluter-pays principle (PPP) is defined as a requirement for those who produce pollution to bear the costs of managing it to prevent damage to the environment and human health, originating from economic concepts like the 'Pigouvian tax' or social tax of negative externalities.
• The PPP is not recognized as a customary international norm because states define and implement it differently within their internal legal systems, and there is a lack of clarity regarding who specifically constitutes 'the polluter'.
• The principle has evolved through several key international milestones: the 1938-1941 Trail Smelter arbitration, the 1968 Council of Europe 'Declaration of Principles', the 1972 OECD Recommendation (the first international document to regulate the PPP), the 1972 Stockholm Declaration, and the 1992 Rio Declaration.
• In the European Union, the PPP has transitioned from a guiding policy to a 'hard law standard' of the legal system, following its inclusion in the 1986 Single European Act.
• While not explicitly mentioned in the UNFCCC, Kyoto Protocol, or Paris Agreement, the PPP is relevant to climate change law through discussions on loss and damage and is indirectly reflected in emission trading schemes, climate finance obligations, and nationally determined contributions.
• The 2019 Helsinki Principles represent a commitment by finance ministers of the World Bank and IMF to implement effective carbon pricing, ensuring polluters pay for carbon emissions via taxes, trading schemes, and the reduction of fossil fuel subsidies.
• To address the disparity between the Global North and South, the document proposes 'specification'—integrating the PPP with the principle of common but differentiated responsibilities (CBDR) so that corporations and countries in the Global North absorb the costs of environmental harms caused in the Global South.
