A long-standing belief among transportation planners and engineers is that wider traffic lanes reduce congestion and create safer streets. A growing body of research challenges this conventional wisdom.
We invite you to join a press briefing call for the upcoming Habitat III convening. The United Nations hosts an intergovernmental conference for member states and stakeholders every twenty years and this third convening of Habitat on Housing and Sustainable Urban Development will take place in Quito, Ecuador from October 17th-20th with over 45,000 delegates in attendance.
This paper examines seven global transport initiatives to reduce emissions. The initiatives are among fifteen presented as part of the Paris Process on Mobility and Climate and the Lima-Paris Action Agenda—both platforms for mobilizing non-state actors under the auspices of the UN Framework...
Local governments throughout Brazil have long-struggled with how to solve the air pollution, traffic congestion and safety issues caused by rising car ownership. The state government of Minas Gerais may have found a solution.
New research from the International Energy Agency shows that cities represent 70 percent of the cost-effective emissions-reduction opportunities between now and 2050. Director for Sustainability Kamel Ben Naceur shared this and other findings at a recent WRI event.
The Coalition for Urban Transitions is one of the first international initiatives to examine the economics of sustainable cities. The Coalition will put urban infrastructure investment where it belongs—at the heart of national economic development planning.
New WRI research comparing high-carbon and low-carbon investment in transportation shows that the low-carbon path offers potential savings of $300 billion a year and is within existing financial flows.
This working paper seeks to elucidate the current estimates for transport infrastructure requirements, looking at a series of reports that consider projected global infrastructure needs in the coming few decades, and provide or quote a cost estimate for these needs.
Recent economic research estimates a $4.1 to 4.3 trillion annual investment gap between the urban infrastructure we have and the amount we need. That's why WRI Ross Center for Sustainable Cities, C40 and the Citi Foundation are partnering to help cities around the world accelerate the implementation of low-carbon urban solutions.
