Implementare il profilo ambientale e la circolarità delle risorse negli appalti pubblici di riqualificazione del costruito

The progressive changes in climate, together with the obvious environmental impacts of human activities on the planet, as well as the continuous depletion of primary resources, make the adoption of the paradigm of circularity in the processes of transformation and management of the built environment increasingly stringent. The European Union, since the early 2000s, with the enactment of a complex system of communications and protocols geared toward reducing the environmental impacts of human activities, has launched a process of reconverting our societies toward a safer future for the next generations. This scenario includes the introduction of green public procurement to orient public purchasing toward a greener horizon. Italy, unique in Europe, in 2016 adopted and then in 2017 updated the decree on minimum environmental criteria in public procurement. However, due to the complexity of the phases of the construction process, together with additional difficulties related to the construction market and the approach of technicians and public administrators, have so far partially rendered the legal instrument ineffective. After a brief examination of the decree and a reconstruction of how the minimum environmental criteria are applied along the stages of the construction process, thanks to a collaboration protocol with the Sardinian Region, a first ongoing experimentation is presented regarding the introduction of the criterion of circularity of resources in the regional price list of public works. This is with the aim of implementing an effective initiative of environmental education among operators in the sector and, at the same time, contributing to the reduction of the environmental impacts of construction and to introduce circularity criteria by acting from the inside, that is, starting from the site work and the materials used in the construction intervention
