Apart from the fact that most of the Mayor’s initiatives need to be expanded (for example I’d triple the cycling budget), the main policy sticking point between the Greens and Ken Livingstone is that he still wants to build an enormous motorway bridge over the Thames Gateway. This is a policy remaining from his first term in office (before he needed our Green votes in the Assembly to pass his budget) and it would be disastrous for both Londoners and the environment. There will be a huge increase in noise and traffic pollution in east London, and is not the way to solve the transport infrastructure problems facing Londoners.
I’d spend the money on new train and tram services instead and reduce the need for car travel, rather than build more roads, which has never been shown to improve traffic problems.
