From the descriptions and analyses of the two cases study Luca Berchicci suggests that a high level of environmental ambition increases the complexity of the product innovation process. Moreover, a high level of environmental ambition may hamper a product innovation process because it may lead the developers away from the market that their product is to serve. Accordingly, this book attempts to explain and predict how environmental ambition influences new product development processes. This claim provides a theoretical contribution to existing research in both product innovation and green product innovation. Moreover, this book provides an original and deep insight on the diverse facets of greening.
