Road transport accounts for 15 % of global emissions and 45% of this comes from cars and buses, so given that new technology is now available to remedy this, this is the next important frontier for getting our Green House Gases (GHG's) down and limiting climate change. The most popular type of Zero Emission Vehicle (ZEV) at present is the Electric Car (EV) which has the potential to reach a 90% market share by 2030, but only if strong policies support this direction. It also presupposes that there will be sufficient renewable energy available to support so many electric vehicles. Otherwise emissions will continue to rise. Emissions are also created in the manufacture of such vehicles - an estimated 40 -58% of the emissions which would have been produced over the lifetime of a non EV car, so unless this energy also comes from renewables, the switch is not as rosy as it looks, though it is certainly less damaging than building new cars and burning fossil fuels to drive them....
