Climate change and other environmental threats require urgent government action. This policy paper discusses how governments can use better regulation instruments (good regulatory practices, risk-based and agile approaches, regulatory delivery, international regulatory cooperation, economic regulators, and behavioural insights) to design, implement and evaluate efficient and effective regulations for the environment. It explores the challenges governments face and presents good practices for environmental and other regulations, to ensure that all policy instruments coherently pursue environmental goals. Finally, the paper suggests how regulatory policy systems can meet present and future environmental challenges. It argues that to fully exploit the potential of better regulation for the environment, governments should implement measures that ensure an inclusive, cooperative, outcome-based and global approach to regulating.
