The research and innovation project TREE (Transition to Efficient, Electrified Forestry Transport) is a large-scale initiative focused on electrifying truck transport in the Swedish forestry sector.

In the project, twelve fully electric trucks are being tested at seven demonstration sites ranging from Småland to Norrbotten. At these sites, advanced electrification systems are being developed, featuring innovative solutions related to charging infrastructure, transport planning, and business models. In addition, an electric timber trailer and a mobile charging station are being developed to extend the trucks’ operating range. The TREE project will also identify barriers to electrification, such as legislation and organizational culture.

Broad collaboration

TREE brings together 23 stakeholders, including forestry companies, vehicle manufacturers, logistics companies, and research institutions. The long-term goal is for half of all newly purchased trucks in the forestry sector to be electrified by 2030. This would reduce carbon dioxide emissions by approximately 260,000 tonnes per year. The intention is for the forestry industry to serve as a testbed where knowledge and solutions can be transferred to other transport-intensive industries, thereby accelerating the transition of the entire transport sector.
