Transport currently contributes about 27% of the total EU greenhouse gas (GHG) emissions. In a trend 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.

Given the overall EU GHG reduction targets of -20% until 2020 compared with the emission levels of 1990 and of -60 to -80% until 2050 (even -95% is debated), it is obvious that in the future (1) the transport sector as a whole 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 research strategies and transport policies have to be developed to efficiently and effectively meet these reduction targets for the medium to long-term. To provide such strategies to meet the GHG reduction targets is the objective of the GHG-TransPoRD project, of which the main results are summarised in the following.
