Transitioning to zero-carbon transport globally is essential to keep climate change in check. Yet seven years after the Paris Climate Agreement, transport emissions are still rising. In a new op-ed, Nina Elter argues that a radical shift in our approach to transportation sustainability is required. Every year, governments around the world invest more than US$700 billion in road infrastructure. While these investments yield significant economic and social returns, transport continues to generate large costs on societies, in the form of harmful emissions, traffic injuries and lost time due to congestion.
