On November 6, 2018, CSIS hosted a workshop on “Transportation in Emerging Economies.” The Chatham House Rule event convened representatives from government, international organizations, think tanks, academia, and private businesses. The group gathered to explore the economic, environmental, and social drivers of urban transportation and mobility in emerging economies. The focus was on the interplay between transportation and energy consumption and the potential to disrupt conventional modeling and planning with new, multi-modal transport policies and investments, new vehicle technologies, and changing business models. This workshop was part of CSIS’s ongoing work on energy and development. There were five main takeaways from that wide-ranging conversation.
