THE NEW CAM AND DIASEN SOLUTIONS: A CHANGE THAT STARTS WITH MATERIALS

The Ministerial Decree of 24 November 2025, which comes into force on 1 February 2026, is an important measure in construction and regulatory sustainability. It updates the Minimum Environmental Criteria (CAM) and places strict emphasis on sustainable materials in public procurement for construction and renovation.
The new CAM are part of Italy’s strategy to integrate stricter environmental criteria into public design, the awarding of works and maintenance contracts, promoting energy efficiency, the use of sustainable materials and ESG (environmental, social and governance) criteria in tendering processes.
In short, the Ministerial Decree of 24 November 2025 makes the environmental requirements for public works stricter and more modern, aligning them with the challenges of sustainability and with new European and national regulatory standards.
Materials will be assessed on three fronts:

• Low environmental impact. The decree encourages the use of products with measurable sustainability characteristics, favouring those with recycled or reused content and with environmental product declarations (EPD/LCA) that certify their actual impact over the building’s life cycle.
• Circularity and traceability. The new CAM strengthen the management of materials along the whole supply chain, requiring traceability and technical documentation that demonstrates compliance with environmental specifications and encourages design and purchasing choices oriented towards circularity and sustainability.
• Rewards. In addition to the mandatory minimum requirements, the decree introduces reward criteria in tenders for materials and technologies that go beyond the minimum required, for example with better environmental performance, higher recycled content or voluntary sustainability certifications

All DIASEN insulation materials comply (no SVHC, no HCFC, no Pb, CE marked, low/zero VOC), as shown by test reports from accredited laboratories and by recognised indoor certifications and labels. In parallel, our paints contain no substances hazardous to the environment.
Diasen solutions therefore offer structural advantages, because our systems are far better suited to earning reward points than many of the traditional solutions on the market.
Traditional external insulation systems, for example, may meet the minimum CAM requirements but rarely trigger reward criteria, because their recycled content is often limited or standard, EPDs are often non-existent, there is little real recyclability at end of life, and they make only a weak contribution to improved LCAs.
Diasen systems, on the other hand, use materials derived from renewable raw materials, are formulated with a significant content of recycled or recovered material, offer design options involving materials or components with better LCA values, and are characterised by VOC values far below the CAM limits, ensuring better indoor air quality.

• In this context, the centrality of LCA (Life Cycle Assessment) and EPD (Environmental Product Declarations) in Diasen solutions should be highlighted.

Diasen products are formulated and certified using an approach based on Life Cycle Assessment (LCA), an international methodology (ISO 14040/44) that evaluates environmental impacts across the entire life cycle: raw material extraction, production, transport, use and end of life.
Every product family is also backed by verified EPDs (Environmental Product Declarations), which provide complete, reliable and comparable environmental data. These declarations cover all stages of the life cycle, allowing direct integration into project LCA analyses.
In short, Diasen products are a more sustainable and “rewarding” solution than traditional materials, thanks to the integration of certified LCA and the transparency of environmental data.
In conclusion, Diasen systems are not only compliant but also enabling for tenders and public projects of high complexity.
