In April 2017, the Solberg Government submitted the white paper National Transport Plan 2018-2029 (Meld. St. 33 (2016-2017)) to the Norwegian Parliament. One of the main goals of this plan is "Reducing climate emissions in line with the transition to a low-carbon society and reducing other negative environmental impacts", and for the 12-year period, the following goal has been adopted: "Reducing climate emissions in line with the Norwegian climate targets". In a white paper from 2017 (Meld. St. 41 (2016-2017), the Government set a working target of a cut of 35-40 % in emissions from the transport sector by 2030 compared with 2005 in order to support efforts to reduce emissions in the transport sector. This target is based on the assumption that the technological maturity of zero-emission solutions in different transport segments will improve so that they become competitive with fossil-based transport solutions. In their most recent political platform (Granavolden platform), the government has gone even further, and set as an ambition to reduce emissions from the transport sector by 50 % by 2030 compared to 2005. This ambition is also contingent on the technological maturity.
