The Cradle to Cradle Certified™ product standard steers designers and manufacturers through a continuous improvement process in which the product is assessed in five quality categories, i.e.; material health, material recycling, renewable energy and carbon management, water management and social justice. For each category, the product is given an individual performance assessment with the lowest performance level being considered the overall assessment of the product.
The Product evaluations are carried out by qualified, independent organisations. The evaluations are then viewed by the Cradle to Cradle Products Innovation institute, which issues the Cradle to Cradle Certified ™ licences. For recertification, the manufacturer must show every two years the efforts he has made to improve the product.
