More than one year ago, the 13th and 21st of January 2008, I wrote in the blog about a new proposal for European directive. As the intention was clearly stated, to bring harmonisation by giving guidance to how to calculate the environmental impact of vehicles, I had great hopes for the directive to bring us a common view.
Today each major city have their own interpretation of environmental friendliness. Some put priority to local fuels, others to electric vehicles, a third experiment with hydrogen. Beware, I once did that too. Luckily only the instrumentation died. The market for environmental prioritised products is relatively small already. It would be beneficial for all to agree on a common view.
But, when the directive for Promotion of clean and energy efficient transports was agreed unfortunately it opens for a series of options and parameter spans that in practical terms can not bring the harmonisation. This means that the stake holders needs to agree on a method to measure and calculate life cycle emission cost as proposed in “article 5” in order to achieve the harmonisation.
