The Norwegian government has decided to develop an action plan for national implementation of the UN Guiding Principles on Business and Human Rights (hereafter Guiding Principles). This mapping and gap analysis has been conducted as a contribution to that effort. The study identifies the measures that are relevant to the state's duty to protect human rights against infringement by business. The aim has been to identify areas which should be a focus during development of the action plan. This study consists of two parts: a survey of Norwegian public bodies and their relevance to business and human rights, and the identification of the gaps between Norwegian state practice and the standards set out in the UN Guiding Principles. The study has attempted to identify some of the risks of human rights violations by business and the corresponding human rights protections – or gaps in protections - within the jurisdiction of the different ministries.
