A large number of these challenges are diffuse issues which have, over the years been targeted by significant and sizable regulatory frameworks and yet the challenges persist-energy efficiency is one such issue and is the focus of this article. Increasing monitoring or enforcement to achieve improvements in regulatory compliance is too expensive in the context of diffuse problems due to the scale and costs such activities would entail. We suggest a focus on the fit between regulatory frameworks and norm creation may identify more fruitful routes to regulatory reform. Drawing on the 'interactional account of law' as a framework, this research uses new empirical data from a survey and a set of interviews to investigate the failure of energy efficiency regulatory frameworks at achieving energy efficient norms of behaviour in industry. We look at Canada and the UK as our case studies and our emphasis is on industry actors as they represent a significant and yet understudied area of society. We find that though existing regulatory structures seem adequate to generate general shared understandings around obligations to engage in energy efficiency actions, more specific shared practice around actually engaging in these actions remains elusive, resulting in a failure to engender norms of behaviour. These failures, we suggest, link directly to an inadequate fit between the regulatory tools and Fuller's criteria for the internal morality of law. 收起
