Environmental quality between regulatory synthesis and project verification

Regulatory references governing design activities have gradually expanded, and national and EU regulations often overlap redundantly. This aspect is particularly evident in environmental obligations, where the Italian requirements about Minimum Environmental Criteria (CAM) have been supplemented by the constraints of the Do No Significant Harm principle (DNSH) introduced for all PNRR (National Recovery and Resilience Plan) measures. A process of rationalisation and synthesis has been conducted for the regulations to address their interpretational complexity, enabling the differentiation of overlaps and novel elements. The result is a tool to support designers, validating authorities and administrations responsible for measures. It is helpful in guiding design choices, monitoring compliance with different requirements and verifying environmental quality.
