Today, greenhouse gas emissions from the transport sector account for almost a quarter of European emissions, almost three-quarters of which are emitted by road transport. The transportation sector is the only one whose emissions have increased steadily since 19901. At the local level, air pollution, a problem that European cities are increasingly tackling, is responsible for 400,000 premature deaths per year 2. Some other health consequences due to the transport sector, such as noise, are also often neglected, estimated at 40 billion euros per year by the European Environment Agency. Now more than ever, Europe must resolve this triple equation in order to reconcile mobility and environment.
