The Fuel Quality Directive (known in the Brussels bubble by the acronym FQD) is the missing link in the Barroso Commission's 2020 climate and energy package. This law aims to reduce the carbon intensity of Europe's transport fuels by 6% by 2020. But its real impact depends on its ‘implementing measures’. These measures rank different types of biofuels and fossil fuels based on their greenhouse gas emissions. They also set up rules requiring oil companies to report the carbon intensity of the fuel they supply. Because of fierce lobbying by oil companies and the Canadian government, the FQD remains unimplemented to this day. This timeline shows the delayed progress of the FQD.
