Transport infrastructure is one of the main contributors to the increase of carbon emissions. But decarbonising the industry is likely to be challenging given that transport demand has continued to rise. In the OECD, passenger transport volumes in 2050 are expected to be 10% to 50% higher than in 2010. Freight transport is expected to grow by 50% to 130%.

How will these twin challenges play out? In this video, the Economist Intelligence Unit investigates how to make transport more sustainable.
