This is the philosophy behind the Monaco Smart & Sustainable Standard (S3), a certification program designed to assess and support marinas, yacht clubs and nautical centers in their transition towards higher standards of sustainability and operational excellence. As José Marco Casellini, CEO of M3 Monaco, explains, the S3 Label is designed as a structured assessment rather than simply a sustainability badge. “We come, we assess a project, and we verify if this project follows all the criteria coming from sustainability, environment, methodology, operational skills as well, and procedure.”
