Product development has a major impact on the cradle-to-cradle principle. Anticipating the 4Rs - reduce, reuse, recycle and replace - in the product development process enables new design concepts and the use of new eco-friendly materials. The dialogue addresses, among other aspects, the importance of weight reduction, the transformations in interior design as well as the customer’s perception of sustainability.

Discussion topics:

  1. Is sustainability relevant for car buyers?
  2. What makes weight reduction so important?
  3. How is the interior design changing?
  4. Why are mono materials of increasing importance?
  5. Paying more money for natural materials?
