Indeed, 0-emission target (i.e. no car, truck, bus, train new or old circulating emitting CO2) for London is 2050. However, there is a trend at the moment both in local government and national one. If that is followed by actual investment in charging infrastructure, sometimes between 2020-2030 electric cars could reach critical mass. At the same time, some region and countries of Europe are already thinking going backward on fiscal encouragement to buy an electric car. In Europe the major part of the fuel cost is taxes, and at some point they will need to find something to tax electric cars on, doing it too early could kill electric cars momentum ... so wait and see.
