This is the English edition of the summary of a report submitted by the Norwegian Environment Agency to the Ministry of Climate and Environment. The report describes positive global trends in emissions and contains a sector-by-sector mitigation analysis of Norway’s transition to a low-carbon society, using the emission reductions the IPCC identifies as necessary to achieve the two-degree target in its Fifth Assessment Report. Further, the report describes what can be done in Norway to achieve these emission reductions, and reviews measures that can be implemented by 2030. The measures are divided into mitigation packages on the basis of assessments of their costs and feasibility. Possible consequences of the measures for the energy sector are discussed.
