The product of the Clean Energy project is a policy paper, a roadmap of recommendations that summarizes the current status of sustainable transport fuels and identifies policy instruments necessary to increase the share of sustainable energy options in Nordic tourism. Requirements for energy and fuel-related infrastructure have been taken into account, highlighting their importance to support the journey toward carbon neutrality. Input and insight for the report have been gathered through a series of workshops in the Nordic countries and online over the project period 2019-2021, ensuring the incorporation of insight and experience of a wide range of stakeholders within the sector.
