Every January since 2003, EMBARQ - The World Resources Institute Center for Sustainable Transport, has convened senior decision makers and professionals from across the country and around the world to share the latest experience, information and best practices in transportation, air quality, and climate protection. The first event was called Diesel Days and it focused on the US Environmental Protection Agency’s heavy-duty diesel and low sulfur fuel rules and what they meant for Mexico City and other places where EMBARQ and its partners were working. By 2004, we had renamed the event Transforming Transportation and since then we have covered a wide range of topics focused on the provision of safe, clean, and affordable transport services. The World Bank has been an annual partner in hosting Transforming Transportation, and increasingly, the event has been co-organized by other international development banks. This year’s partners include the Inter-American Development Bank, the Asian Development Bank, and the Partnership on Sustainable Low Carbon Transport.
