What does 50by50 mean in my country?
50by50 is an overall objective, based on existing evidence, of what existing technologies could deliver in terms of improved fuel economy. It does not favour any of those technologies, nor does it exclude the benefits which other technologies such as electric cars could bring. It is a device to promote the debate about what each country and region could and should do to improve fuel economy in the best interests of local people and the whole planet. As such, it does not prescribe any policy ‘blueprint’, but rather offers a toolkit of possible approaches to the issue. Experience is already showing us that the precise mix of these tools will differ from country to country and region to region.
