There is an increasing dissatisfaction about how risk is regulated, leading to vivid debates about the use of ''risk assessment'' and ''precaution''. As a result, academics, government officials and industry leaders are calling for new approaches and fresh ideas. This book provides a historical and topical perspective on the alternative concept of ''Tolerability of Risk'' and its concrete regulatory applications. In the UK, Tolerability of Risk has been developed into a sophisticated framework, particularly within the health and safety sectors. It is expected to guide decision-makers when applying their legal obligation of keeping risks as low as practically reasonable. Could Tolerability of Risk become a wider source of inspiration across the full scope of risk analysis and management? Written by leading academics and risk practitioners from industry and government, The Tolerability of Risk presents a summary of theoretical perspectives on risk approaches, providing a detailed elicitation of the methods and approaches used to build the Tolerability of Risk framework and examining the prospect of universal application of that framework. From nuclear power to environmental pollution, climate change and drug testing, the Tolerability of Risk framework may offer a workable, pragmatic solution for balancing risks against the costs involved in controlling them, as well as developing the institutional capacity to make effective decisions in all jurisdictions worldwide.
