ABSTRACT
What is Comparative Risk Assessment? Simply put, comparative risk assessment (CRA) uses the conceptual and methodological framework of environmental risk assessment to compare the human health, ecological, and quality-of-life impacts of different environmental threats in a certain geographic area. It brings together the best available information about relative risks to help policy-makers, program managers, and citizens answer the question: ‘Of all the environmental challenges facing our city, which are the most urgent?’
