The Life Cycle Assessment Dataset contains data used to perform the cradle to grave LCA methodology to quantify the carbon and energy intensity of the proposed device configuration. The dataset includes input data obtained through a combination of project partner contributions, peer-reviewed literature, and pre-existing databases, as well as results of environmental impacts found through the application of LCA techniques in the SimaPro tool and using Ecoinvent database. These data were compiled and used to conduct a LCA of the LiftWEC device in Work Package 9, to evaluate and inform device design choices. The findings of this assessment were presented as part of Task 9.4 and included in Deliverable D9.4, titled "Life Cycle Assessment of the LiftWEC Design.
