With the first stop of the “Pietra in Movimento” roadshow in Florence, the PNA Network reaffirms its commitment to promoting the culture of authentic natural stone – a traditional building material that is now at the forefront of new technical, aesthetic and sustainable applications in contemporary architecture. The event provides a forum for dialogue between companies, architects and industry professionals, featuring specialist presentations and national and international case studies.

An EPD (Environmental Product Declaration) is a certified document that describes the environmental impact of a product throughout its entire life cycle, based on verified data in accordance with international standards (ISO 14025, EN 15804) and validated by third-party bodies.

 

In 2025 PNA developed the first sector EPD for natural stone: it does not concern a single product or company, but the entire industry. It confirms, with objective data, the low environmental impact of the supply chain, especially in terms of CO₂ emissions, from quarrying to end of life. The study was previewed at Marmo+Mac 2025.



With the “Stone is…” Forum held in Venice during the 2025 Architecture Biennale, the PNA Network reaffirmed its role as a key player in promoting the first building material in history—a meeting point between nature and culture. The event featured nationally and internationally renowned speakers.



PNA – Authentic Natural Stone Business Network is the point of reference for more than 40 companies, entities and organizations working together to promote and protect the competitiveness of authentic natural stone.

 

Our goal is to enhance the tradition, excellence and versatility of this extraordinary material, raising awareness among architects, designers, industry professionals and all those seeking quality solutions.
