Cycling is healthy, cheap - and as modes of transport go, they don’t come much greener. Worldwide, transport is responsible for nearly a quarter of all carbon emissions, with road transport alone accounting for 75% of that. But so far, most discussions on greening the transport sector have focussed on electrifying our cars, trucks and buses – overlooking the vital role that bicycles could play in the climate transition. In fact, experts say that we’re unlikely to meet our short-term climate goals without more people getting on their bikes. So what needs to change to make that happen? We look at what’s been done on streets of Bogota, New York and Kampala to get more people cycling across the world.
