This article analyses the new text of the Public Contracts Code with reference to the principles of sustainable development and environmental protection, neither of which are expressly mentioned among the new provisions. This examination provides an opportunity to reconstruct, according to Eu and national law, the role of the contracting authorities in pursuing environmental sustainability through public procurement. The approach followed in the new Code seems to be in line with the previous mandatory-rigid approach. Nevertheless, according to the principle of trust, corrective “functional” measures can be adopted to ensure that the processes of public procurement minimize damage to the environment and foster innovation.
