Transition in the public sector to transport driven by renewable fuels is slow, which affects the business sector’s ability to change and the conditions to reach the target of 70 % reduction of greenhouse gas emissions in the transport sector by 2030. Through knowledge-enhancing, behavioural and information-based activities, the project will support participating actors in Stockholm County in the transition to renewable fuels. The project will, as the public changes requirements in, for example, procurement also support the business community in its opportunities to meet changing requirements. The project will have contributed to an increased and better functioning regional market for fossil-free transport and regional production and use of renewable fuels. Municipalities participating in the project have reduced the climate impact of their own transport work by at least 10 % on average compared to 2019. The aim of the project is to have contributed to reducing greenhouse gas emissions from the transport sector by at least 4000 tonnes of CO2 eq. per year.
