Cradle to Cradle is a certification process where companies that have registered start a process where their products are assessed, certified, improved upon, assessed again, and so forth. While companies take on the C2C label when they sign on, by signing on they are making a commitment to improve their product according to the independent assessment of the C2C agency. You can look a company up on the C2C site to see what level of compliance they have reached in this certification process.
