Cradle-to-cradle is a design concept in which products are created according to the principles of circular economy. The framework has been created by The Cradle-to-Cradle Products Innovation Institute, which aims to support sustainable development and circular change, by introducing a replaceable, customizable, and upgradeable approach to products. Bang & Olufsen’s approach is an addition to the Institute’s specific requirements in the standard.

The elements of a cradle-to-cradle version 4.0 certification

A certification process measures the environmental and social sustainability of the product based upon five categories:

- Material health

- Product circularity

- Clean air and climate protection

- Water and soil stewardship

- Social fairness

Products that meet the transparent criteria of this rating system audited by a 3rd party, receive the cradle-to-cradle certification, which spans over five categories from basic to platinum. The Beosound Level was bronze certified and among the first products to receive the new version 4.0 certification.
