The precautionary principle and management of uncertainties in EIAs-analysis of waste incineration cases in Finland

摘要

This article examines whether and how the practice of environmental impact assessments (EIAs) serves the idea of the precautionary principle. The article provides an empirical examination and description of how uncertainties and risks were dealt with in conclusive outputs of EIAs of chosen example cases of Finnish waste incineration projects. The analysis focuses on the time when several incineration projects were in the planning phase in Finland and the effects of this development were seen as being controversial. The findings of the analysis are evaluated against a legislative and theoretical framework. The challenges and strengths of the practice are identified. The article suggests that EIA as an environmental policy tool can promote the pursuit and the application of the precautionary principle. In addition, uncertainty analysis and risk communication in EIA could benefit from a shift towards more collaborative knowledge-making.
