On May 14, European Union Climate Action Commissioner Connie Hedegaard defended the application of greenhouse gas ratings to fuels used in the transportation sector. Originally proposed in October 2011, the plan would apply intensity ratings to fossil fuels as part of the 2009 Fuel Quality Directive. The European Commission placed a hold on the proposal in April 2012 until an economic impact assessment had been completed. Ms. Hedegaard said the ratings would be fair when judging oil sands fuel, but the Canadian government has said the system would be discriminatory because the calculations are wrong.
