This study takes as its terms of reference the optimal role for transport fuels in the future energy mix from an environmental perspective. It develops a model that assesses a number of possible technological pathways to a future low carbon transport system, measured against a range of energy mix scenarios. The focus is specifically on the relative carbon benefits of hydrogen and bio-energy options, as well as more efficient vehicles. This study is based on a ‘well-to-wheel’ analysis that accounts for emissions both from vehicles and from upstream fuel production.
