Four years ago, the professor at the University of California at Davis and a team of engineering students created a plug-in vehicle. And because electric power is much more efficient per mile , the amount of pollution and carbon dioxide sent skyward would still be far less than an automobile engine, his analysis shows.
Director at the ETA, Andrew Davis, said: “Car makers can build green cars, but they need us to buy them. Portuguese drivers are the greenest in Europe when it comes to buying cars with an average CO2 rate of 138g/km (eg. The average British driver comes sixteenth in the list with 158g/km (eg. VW Passat).
At the same time, we’ve been able to take old, polluting cars off the road and help consumers purchase fuel efficient vehicles.”. The scheme has not been without controversy though; one UC Davis transportation economist Christopher Knittel criticized the scheme as a costly way to reduce carbon emissions.
