"In early 2007 the EU adopted the objective to limit climate change to 2 degrees Celsius. More specific, the European leaders defined a target to reduce greenhouse gases by at least -20% until 2020, or -30% if an international agreement is achieved, compared with the emission levels of 1990. Until 2050 the reductions of the EU emissions should reach -60 to -80%. Transport currently contributes about 27% of the total EU greenhouse gas (GHG) emissions. In a baseline scenario this share is expected to grow due to continued strong growth of transport demand, in particular of freight transport and air passenger transport, and slower efficiency improvements than for other GHG emitting sectors. The existing GHG reduction targets do not force reductions of the transport sector, though for specific modes like air transport the planned inclusion into the European emissions trading scheme (EU-ETS) will indirectly impose targets for these modes in a few years. Thus it is obvious that in the future (1) the transport sector will have to contribute to GHG emission reductions such that (2) reduction targets for the different transport modes have to be anticipated and (3) aligned R&D strategies and transport policies have to be developed to efficiently and effectively meet these reduction targets for the medium to longterm. The GhG-TransPoRD proposal aims to contribute to the development of a R&D strategy for the EU to reduce the GHG emissions of the different transport modes (road, rail, air and shipping) linking this R&D strategy with the available policy measures. Thus the proposal supports the FP7 objective to develop integrated, ""greener"" and smarter transport systems."
