Una metodologia per l'analisi ambientale, economica e sociale di progetti per la produzione di energia da fonte rinnovabile

The evaluation of the sustainability of projects is a topic of great debate. The 2030 agenda and the circular economy have focused attention on the three aspects of sustainability: environmental sustainability, social sustainability and economic sustainability. This work aims to identify indicators for each of the aspects of sustainability by investigating the methodologies used in the literature in different fields which, starting from LCA, evolve into S-LCA, SIA using the tools of hieratic analysis, network analysis , circularity indicators and the most used ones such as Impact 2002 and Cumulative Energy Demand. Renewable energies, and specifically wind farms, are the case study examined in the research work. The evaluation of the sustainability of the project finds its goal within the decision-making process by answering the questions "What social impacts do new projects bring?". “What elements can be highlighted and shared to prevent the project from being unacceptable?”. The innovation of the research consists in measuring all the indicators by elaborating a new method which is not only sectorial but which involves indicators of the three aspects of sustainability and these derive from a correct analysis of the project context. A methodology that is not closed to a finished result but that is a proactive tool in the decision-making process.
