TOSCA consists of eight work packages, drawing on expertise from seven organisations across Europe. The first three work packages, primarily literature-based, assess state-of-the-art technologies for road vehicles, aircraft and railways along with their associated costs and potential for reducing greenhouse gas emissions. These studies are accompanied by a lifecycle analysis of the energy use, costs, emissions and resource potential of current and future transportation fuels in work package 4, and an assessment of the current capacity of the European transport infrastructure in work package 5. Once these studies are completed, their results are used as input into work packages 6 and 7, which evaluate the uptake of different technologies, potential for reduction in emissions, and likelihood of realisation under a number of different future scenarios with and without policy input. Finally, dissemination is handled by Work package 8.
