What role does transportation play in reducing carbon emissions and other pollution?

Transportation, the source of nearly a third of the United States’ greenhouse gas emissions, is the fast-growing source of carbon pollution globally.

In order to keep global temperatures below levels that are dangerous to humans, we must make a large-scale shift away from driving alone. Thankfully, even small changes, such as a modest increase in bicycling, can keep massive amounts of carbon out of the atmosphere.

If we can reduce the number of cars on the road and, more importantly, the number of total trips, then we can cut not only the carbon pollution threatening the climate, but also the particulate and ozone emissions that carry serious health consequences for communities living near major highways.

The smart-growth and transit revolution of the last decade or two has had only partial success. Despite some revitalized cities and some new transit, sprawl remains dominant in America. On the heels of this incomplete revolution comes a new one: automated vehicles (AVs) that are certain to alter land use and transit. As the predominance… Read more »

Autonomous vehicles appear to be wonderful in many ways. They will help seniors and young people get places. They’ll reduce traffic accidents and making driving safer. They will eliminate vast swaths of parking. Then again, they may worsen the most harmful aspects of sprawl. They could create lost tax revenue. They may cripple public transit…. Read more »
