    Abstract [en]

    The amount of organizations that choose to work with sustainability is increasing due to the potential competitiveness it causes. Working with sustainability may include sustainability evaluations, which can be done through the LCSA analysis method. The purpose of this report is to evaluate and analyze a manufacturing company's current climate impact due to carbon dioxide equivalent emissions from diesel-powered forklifts within internal material handling. Further, the report aims to illustrate how a sustainability evaluation can be conducted to identify ecological, economic and social impact. In the report, a sustainability evaluation of forklift systems is performed to identify the theoretically best alternative, compared to a case company's current situation. The method used for the sustainability evaluation is LCSA analysis. In addition to the results of the sustainability evaluation, the interface between theoretically and practically best forklift system alternatives is considered.  The case company Volvo GTO in Skövde, currently have 18 diesel-powered forklifts, which have different capacities and functions. The current fuel for all forklifts is Diesel Mk1. The flows today generally set high demands on the forklifts technical capacity, for example on, travel speed, climbing ability, traction force and lifting and lowering speed. In the year 2017, the 18 diesel-powered forklifts contributed with a climate impact of approximately 237 tonnes of carbon dioxide equivalents, considering the entire life cycle of Diesel Mk1 and the forklift fleets total run time.  Regarding the sustainability evaluation LCSA analysis, it is performed on forklift systems powered by Diesel Mk1, HVO-Diesel, lead acid batteries and lithium-ion batteries within the capacities 3.5, 5 and 8-tonne. The analysis considers the three pillars of sustainability. Further, the technical specifications of the forklift systems are considered and compared with the current diesel-powered fleet. Generally, a lower technical capacity can be seen in the electric forklift systems, which may affect the ability to implement those at the case company. Theoretically lowest ecological and social impact can be seen within the lithium-ion battery-powered forklift systems, the lowest impact on the economic pillar is seen in the lead acid battery systems. Based on the case company's current flows and demands, the authors recommend HVO-Diesel-powered forklift systems, as they have the same technical capabilities as well as lower ecological and social impacts. Limitations has been set for the reports analyzes, regarding process boundaries and impact indicators. For future sustainability evaluations, the authors recommend that wider process boundaries and more impact indicators are applied to identify the total impact within the pillars of sustainability. The report comprehends examples of impact beyond selected process boundaries, such as emissions affecting over time or exploitation. During the progress of this report, information gaps have been discovered in different areas. Regarding research of sustainability evaluations, proven methods are lacking. Therefore, established methods for evaluation are desired. A gap in research of forklift theory has also been noted.
