Naljepnica sa oznakom ˝Silver Product˝ Radi se o naljepnici/etiketi koja označava da proizvod udovoljava određenim kriterijima i kvaliteti.

The Cradle to Cradle framework has outlined a vision to guide product design and manufacturing, and the certification program recognizes varying levels of achievement towards that goal.

There are four levels of product certification: Basic, Silver, Gold, Platinum. In order to be certified at a certain level, a product must meet the minimum criteria for that level in all five criteria categories: Material Health, Material Reutilization, Renewable Energy Use, Water Stewardship, and Social Responsibility.
