The United Kingdom's Office of Climate Change reports that a number of barriers inhibit households from reducing carbon emissions, even though reducing carbon emissions generally results in reducing household costs. In this paper, the Office of Climate Change identifies policies to overcome barriers to carbon savings.

This report is a comparison of the laws of the United Kingdom and of the United States that govern criminal and intelligence investigations of terrorist activities. Both systems rely upon a series of statutory authorizations: in the case of the United States primarily the Foreign Intelligence Surveillance Act and the Electronic Communications Privacy Act; in the case of the United Kingdom, the Regulation of Investigatory Powers Act, the Police Act, the Intelligence Services Act. Among other differences, the U.S. procedures rely more heavily upon judicial involvement and supervision, while those of the UK employ other safeguards. The UK procedures afford greater latitude to arrest, detain and supervise suspected terrorists than those available in the United States.
