Abstract
The European community becomes more and more transport intensive. Especially the long distance road transport of goods has grown for a long time significantly faster than industrial production. Market economies have a superior efficiency and show a dynamic development which cannot be sustainable as it is. Transport policy is challenged to set conditions in a way that market dynamism works in favour of sustainable development. Today the internalisation of the overall social and ecological cost of the transport sector is therefore seen as one possibility. But the outcoming prices do not easily guarantee a transport of goods compatible with sustainability. Prices covering all costs are not identical with prices in a market economy.
