To address this issue, the JRC assesses the performance of fuel alternatives through its Well-to-Wheels (WTW) analysis carried out in collaboration with the European Council for Automotive Research and the oil companies' European association, CONCAWE. The WTW analysis aims to estimate the GHG emissions, energy efficiency and industrial costs of all conventional and alternative automotive fuels and powertrains in Europe.
The JRC uses economic models and historical trends of cropland expansion in order to map regional changes in land and calculate resulting global GHG emissions. In addition, the JRC developed a guidance document for assessing carbon stock changes in soils and above- and belowground biomass due to the cultivation of biofuel crops.
The JRC also assesses renewable energies outside Europe, for instance in Africa, focusing on knowledge transfer to promote their use.
