Towards More Holistic Environmental Impact Assessment: Hybridisation of Life Cycle Assessment and Quantitative Risk Assessment

Global and local environmental impacts of products or services can sometimes be in conflict with one another. Therefore, the importance of considering both impacts in environmental management must be recognised. Life cycle assessment (LCA) is useful in evaluating global impacts while quantitative risk assessment (QRA) is effective in local impact assessments. The benefits of combining LCA and QRA in this regard have been recognised. Advantages and disadvantages of different hybridisation approaches were critically examined in this paper. There seems to be no single best approach and a method needs to be carefully selected depending on the type of application.
