Sustainable Transportation Could Save the World (and Save $100 Trillion)

Dramatically expanding transit and active transportation over the next few decades could reduce carbon emissions from urban transport 40 percent more than following a car-centric trajectory. And it could also save the world economy $100 trillion.

That’s according to a new report presented recently to the United Nations by researchers at UC Davis and the Institute for Transportation and Development Policy [PDF]. The team modeled the cost and greenhouse gas impacts of two scenarios for the future of world transportation up to the year 2050.

The baseline scenario assumes a business-as-usual approach to transportation. Following this path, transit systems across the globe would grow modestly over the next few decades, while driving would grow considerably, especially in developing nations.
