Gli standard e linee guida per la misurazione delle emissioni di carbonio in edilizia: analisi della letteratura Standards and guidelines for measuring carbon emissions in buildings: literature analysis

Life Cycle Assessment is of paramount importance for building sustainability. Life Cycle Assessment approach, basing on ISO 14040, performs a broad evaluation of all different environmental impacts of construction and building - related processes, but the environmental impact is mainly assessed by carbon emissions evaluation. In addition to this, a traditional cost measurement standard of construction industry, now includes carbon emissions. The last edition of International Cost Measurements Standards ICMS standards indeed, addresses not only costs on a life cycle basis, but also the estimate of carbon emissions. Therefore, a literature review of international standards and guidelines for carbon emission measurement is performed. Actually, carbon footprint can be evaluated basing on the Kyoto protocol principles, and using the Greenhouse Gas protocol jointly convened by World Business Council for Sustainable Development ans World Resources Institute - WIR/ WBCSD GHG protocol - and ISO 14064-1. A simple practical example is proposed to show how LCA methodology can be developed in practice, and how the results obtained from the analysis can be evaluated.
