The carbon footprint of the historic centre of the Municipality of Trevignano Romano - Lazio Region, Italy

Operations to quantify the CO2eq emissions of a given territory encounter critical issues that make the matter more complex because they are rooted in political/economic/social options carried out over time and in other locations; options that “come from elsewhere and far in time” and therefore make partial the technical solutions that are proposed today. Each intervention must therefore be “contextualized in space and time” otherwise the technical initiative in progress, not well understood, can create the misunderstanding of being proposed again, in other territorial contexts with deep and different connotations, with consequent results that are only partially positive. Moreover, each intervention, for an obvious economy of scale, must be correlated at the same time with similar ones and, in any case, all of them must be placed coherently within an economy that today goes towards industry 4.0. through digitalization. This case study precisely because it is placed “today” and “within” a specific context possesses such specificities that it allows (even foreign entrepreneurs, as well as national) to operate adequately. Following the analysis of the most suitable tools for measuring environmental impacts – on the building and urban scale – the carbon footprint procedure has been defined, the working methodology, the technical operations carried out and the calculation methods for quantifying the CO2eq emissions produced by the energy consumption of buildings and transport are illustrated through the indicators for the case study under examination, analysed at 360°. Finally, the proposal for the overall reduction of the calculated carbon footprint is illustrated and concludes with the results achieved and their possible further developments.
