The present report describes the activities performed within MC2.0 Task 5.1. The main goal of this study is to assess the environmental impact via life cycle assessment (LCA) analysis, to provide an environmental roadmap, and to optimize the supply chain for building integrated (BIPV) technologies developed within this project. The environmental LCA is performed according to ISO14040 and 14044 standards, and other available ad-hoc guidelines available for PV or building elements. It includes the life cycle stages from raw material extraction to production of photovoltaic (PV) laminates, until the fabrication of five BIPV end-products, including energy consumption, material production, manufacturing, usage and end-of-life (EOL) treatments. Goal of the assessment is to optimise the BIPV products from a sustainability point of view, providing feedback to the manufacturers on the environmental hotspots identified, but also to demonstrate the resulting low environmental impact and high circularity potential of the BIPV products. This analysis was made by the European Research Academy (EURAC) thanks to the collaboration with MC2.0 project partners: Toegepast Natuurwetenschappelijk Onderzoek (TNO), innovative Windows (IWIN), Scuola Universitaria Professionale della Svizzera italiana (SUPSI), Glass 2 Power (G2P), Schweizer (SCHW) and Polymer Competence Center Leoben (PCCL), who contributed sharing their inventory data to produce the different products and providing their knowledge and feedback.  The obtained results have been compared with the state of the art, to evaluate the sustainability of the proposed solutions and suggest feedback to improve both the circularity and sustainability of their products. In order to deal with the uncertainty and variability of certain input parameters, a sensitivity analysis was also performed. The same inventory datasets have been used to develop an environmental roadmap for BIPV products, more specifically, a greenhouse gas (GHG) footprint evolution roadmap over the years in a prospective way, until 2030 and 2050, with a clear definition of the calculation boundaries. This activity was executed via prospective LCA methodology, by modelling the BIPV production in different future expected market scenarios, considering possible future changes of the background production context (in terms of policies and technologies development), for both materials and energy. For that, two different future global market scenarios were considered, a best and a worst-case scenario, in which the policies related to decarbonisation are applied.    Finally, the supply chain of the BIPV products has been optimized, in order to provide a guideline for the front- and back-end manufacturers to improve the material selection process based on the GHG emissions of transport and electricity of each of the main materials required for the BIPV production. The document is structured as follows: Section 1 will provide an introduction and overview of the LCA framework adopted, and a state-of-the-art analysis of the BIPV environmental sustainability. Section 2 will define the goal and scope of the analysis, while Section 3 will describe the inventory data collected and used. Section 4 represents the core of the LCA results, while in Section 4 the results are used to model a supply chain optimization. Lastly, Section 6 will summarize the analysis and draft conclusions.
