According to the EU Press Room, “The European Commission has released a comprehensive compilation of existing studies on external costs in the transport sector. This handbook, jointly prepared by several transport research institutes, summarises the state of the art as regards the valuation of external costs. The Commission intends to make use of the handbook as one element which prepares the communication on the internalisation of external costs for all modes of transport that is due in June 2008 and a proposal to revise the directive on the charging of heavy goods vehicles.”This Press Release is available in full text.
