A short Global Post video provides an introduction to Mexico City’s “green transportation revolution”, in which electric vehicles are gradually being phased in to replace conventional taxi fleets, bicycle routes are created, modern, fuel-efficient buses extend their coverage, and biodiesel buses have been introduced along a major arterial route.
The initial priority has been on the downtown area of Mexico City, the Historic Center (Centro histórico) . This 3.5-square-kilometer area receives 70,000 vehicles a day, responsible for emitting 10,000 metric tons of carbon dioxide a year. Pollution in this area has been reduced significantly in recent years. City authorities use the Historic Center as a testing ground for pollution-reduction strategies, prior to rolling them out elsewhere across the giant metropolis.
