The study calculates the external and social environmental, accident and health-related effects of transport in Switzerland in 2010. In doing so, previous calculations are subject to a methodological review, and recalculated using fully updated data sources. The external costs of air and waterborne transport as well as non-motorised transport (pedestrian and cycle traffic) are calculated for the first time.Aggregated across the four modes of transport, total external costs come to over CHF 9,400 million for 2010. At CHF 5,500 million, private motorised road transport is the main originator of these external costs, followed by road freight transport at CHF 1,000 million. Air transport resulted in external costs of CHF 920 million, while rail transport accounts for CHF 740 million and waterborne transport generated external costs of CHF 57 million. In addition to external costs of CHF 900 million, non-motorised transport generates external health benefits worth CHF 1,300 million.
