Abstract

In this article a synthesis of formal models for the economic interpretation of the precautionary principle is presented, with their virtualities, limitations and measures to overcome them.

The concept of precaution has great relevance in environmental regulation in the European Union. On the one hand, and despite the somewhat vague nature of legislation, the interpretation of the precautionary principle has seen recent progress with the development of some economic models and their application. There is, however, a need for a regulatory framework for the implementation of this principle in environmental decision-making, i.e., to clarify concepts and management procedures that are appropriate to the nature of environmental risks.

It is therefore important to know the most relevant economic approaches and models with the aim of identifying their contribution to the debate on precaution in the context of environmental risk management and discuss their practical relevance in public decision-making.

2 Current Article 191, paragraph 2, of the Treaty on the Functioning of the European Union. The only explicit reference to the precautionary principle is: ‘European Union policy on the environment shall aim at a high level of protection, (…). It shall be based on the precautionary principle and on the principles that preventive action should be taken, that environmental damage should as a priority be rectified at source and that the polluter should pay’. In this article, paragraph 1 states the objectives of the environmental policy of the European Union: ‘preserving, protecting and improving the quality of the environment; protecting human health; prudent and rational utilisation of natural resources; promoting measures at international level to deal with regional or worldwide environmental problems, and in particular combating climate change.’ Paragraph 3 states that ‘In preparing its policy on the environment, the Union shall take account of: available scientific and technical data, environmental conditions in the various regions of the Union, the potential benefits and costs of action or lack of action, the economic and social development of the Union as a whole and the balanced development of its regions’.

18 In these models, scientific uncertainty (or not proven risk), which characterises precautionary situations, differs from risk (proven risk), which characterises prevention situations, mainly due to its possible reduction with time.

29 Another framework is ‘prospect theory’ (Kahneman and Tversky, supra note 27). The two frameworks have been combined in ‘cumulative prospect theory’ ( Tversky, A., Slovic, P. and Kahneman, D., “The Causes of Preference Reversal”, 80 (1) The American Economic Review (1990), pp. 204–217 Google Scholar.
