WHAT IS CONSIDERED A LOW EMISSION VEHICLE?

The UK government defines a low-emission vehicle as one which produces less than 100 grams of carbon dioxide for every kilometre (0.6 miles) travelled.

Beyond that, there are ultra low-emission vehicles, which emit less than 75 grams of carbon dioxide per kilometre.

And then there are zero-emissions vehicles which, as the name suggests, emit no carbon dioxide or anything else from tailpipes (exhausts), because they don’t even have them. Electric cars are in this category.

A big consideration when looking at emissions, as well as the environmental impact, is cost. Higher-emitting vehicles incur much larger vehicle tax costs in the UK.

Zero-emissions cars mean zero cost in this respect.
