This week marks an important transitional step away from the obsolete technology of dirty fossil fuel vehicles and in favor of electric vehicles that can run on clean energy. The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) has come into force in the EU from 1st of September 2018, leading to much hand-wringing by the traditional fossil fuel vehicle OEMs, whose cars have always been highly polluting, and are now running out of road. The old fig leaf of the 1990s NEDC (New European Driving Cycle) testing regime is being replaced by the updated, more realistic WLTP testing regime, along with its onroad-emissions-testing counterpart, the Real Driving Emissions test (RDE). While still imperfect, these new testing regimes do track real world emissions performance much more closely.
As a consequence, the current generation of fossil fueled vehicles (FFVs) are now officially earmarked by lawmakers as being more polluting in particulates, carbon dioxide, and other harmful emissions. A higher bar is set for their entry on to the market, which will require expensive and complex technology to achieve. They will also be taxed at higher levels than before, and will cost consumers more to purchase.
