By connecting people to services and opportunities, as well as goods to markets, transportation is a key enabler of economic growth. Investing in ports, airports, urban transport, railways, and other transportation infrastructure and services bolsters international trade and develops local markets. A modernized transport sector also can play an important role in a low-carbon economy. Innovative transport solutions underpinned by smart, green, and sustainable technologies can increase efficiencies and reduce the sector’s environmental footprint.
