Sales of battery electric buses are surging, yet a complete technology transition won't happen overnight. Meanwhile, tightening emission standards on conventionally powered buses would have immediate benefits for air quality in many of the world's fastest growing megacities.
São Paulo’s clean bus transition has been delayed for long enough. The negotiations of the Article 50 amendment provide an opportunity for policymakers to put the city back on the right path for fulfilling climate, health, and technology innovation goals. Strong actions would place the city ahead of the curve as more and more cities around the world consider similar transitions to clean bus fleets.
For any city wanting to reduce air pollution from vehicle emissions, buses are an obvious place to start. Mexico City has requested our support, and we will be developing a joint workplan, to kick off with a public workshop in September.
It is possible to mitigate climate change and lower health impacts through less reliance on private automobiles, reduced urban sprawl, higher rates of public transit, and stringent vehicle emission controls.
One clear, shared commitment that stands out in the agreement between California and Mexico to work together on air pollution and climate change, announced Monday by Governor Jerry Brown and President Enrique Peña Nieto, is clean vehicle standards.
This new body, which replaces the Comisión Ambiental Metropolitana, presents an excellent opportunity to raise awareness of the importance of better fuels and better vehicles.
