The focus of this book is on the environmental impact of mobility and how this can be reduced before 2050. Based on scientific evidence, the book provides policy makers with a broad and multifaceted inspiration to develop effective policies on sustainable mobility. Different visions and facets to solutions are put forth by world-renowned experts, with leading international researchers and authors providing contributions on a wide range of topics in the field of sustainable mobility. The book also contains a reflection on a European Union study commissioned by the Raad voor de Leefomgeving en Infrastructuur (Council for the Environment and Infrastructure) and concludes with a description of inspiring cases of multinationals who integrated sustainable mobility in their corporate visions. It was published to coincide with the conference "Keep Moving, Towards Sustainable Mobility," which was held in October 2012 in Rotterdam.
