This report aims to gauge Norway’s fair share of the global response to the climate problem, starting from the recognition that equity is important – in fact, necessary – for addressing climate change. The report focuses on mitigation, although an equitable approach to adaptation is of course equally important. It uses a flexible and transparent framework for equitable effort sharing that is drawn directly from the core equity principles of the United Nations Framework Convention on Climate Change (UNFCCC). The analysis is done using the Climate Equity Reference Calculator, an online tool and database that allows users to select specific equity-related settings relating to responsibility, capacity and other key parameters, and then to use straightforward, standard quantitative indicators to calculate the implied national fair shares of the global mitigation effort. The analysis is based on a range of alternative input selections informed by ethical and empirical considerations that are discussed in more detail within the report. This approach allows the report to contrast Norway's pledged contribution towards the Paris Agreement goals with its fair share, and to articulate what Norway should do in addition to its existing pledge to be in line with its moral obligations.
