You wrote that the issue of certified fuel economy figures is about to explode in the face of the EC. It seems to me that this is more likely to explode in the face of the motorist. If, as regularly experienced, EC fuel consumption figures are much lower than reality and CO2 figures are related to these, then the EC CO2 emission figures must also be lower than reality. This not only underestimates the real emissions from a greenhouse gas point of view, but also from a taxation point of view. Once it is realised that taxation would be much higher based on real life CO2 emissions, then I am sure we can look forward to governments getting even deeper into the pocket of the motorist.
