About the project
Road freight vehicles are key economy enablers, they are employed for the movements of goods, such as food, electronics or raw material. Today’s road freight vehicles are mainly fuelled with diesel and use a significant fraction of the global fossil oil production. Without further policy efforts, oil demand from road freight vehicles is projected to increase considerably. Measures to lower greenhouse gas (GHG) emissions from road freight vehicles include the use of renewable fuels, electrification and the use of fuel cells. All of these alternatives seem viable for medium size distribution trucks, but for heavy duty long-haul trucks the possible alternatives to diesel are less clear.
Life cycle assessment (LCA) can be an important tool to guide policymakers and the direction of technology development. However, from the studies examined in this work, it was recognized that available LCA studies on road freight vehicles do not sufficiently support decision making. Most studies are limited, and therefore, results from different studies are difficult to compare and lead to different recommendations. Problems identified in present studies are the following:
- there is only a limited number of available reports on trucks
- the definition of the vehicle is unclear
- different approaches and system boundaries are applied
- studies are focusing on the present situation and do not include future considerations.
Furthermore, available studies are typically limited by not including equipment life cycle, end of life, analysis of resource depletion and cost.
Since there is no simple solution to lower GHG emissions from heavy duty transport it seems obvious that more LCA studies should focus on this sector. Such studies should be complete and well-defined LCAs also including equipment life cycle and end of life. In addition, it is suggested that the analysis include availability of resources as well as incorporate costs. Finally, to better support decision making, also future developments of technologies and society needs to be considered. Building long-term scenarios with zero net GHG emissions and where all material is recycled is particularly important to obtain fully sustainable heavy duty transport solutions.
