Il valore della sostenibilità per la conservazione del patrimonio. Riflessioni verso una definizione dei prodotti sostenibili del restauro

The conservation risks associated with climate change to which heritage is subjected represent one of the most significant issues arising from the adoption of the 1972 World Heritage Convention. The Outstanding Universal Value (OUV) of World Heritage Listed sites and the conditions of integrity and authenticity, which were essential requirements at the time of their nomination and inscription, may be compromised or no longer be met over time as a result of the effects of climate action on heritage assets. While the value of sustainability has assumed a predominant role in the multiple social, cultural, economic and environmental contexts and is in affinity with many of the theoretical premises within the discipline of restoration, this study aims to reflect on some of the systemic principles and parameters through which a restoration product can be defined as sustainable, considering the material authenticity and uniqueness of World Heritage architectural artefacts, and the spatial-temporal implications related to the conservation of cultural heritage
