IEA shows benefits of improved energy efficiency of urban transport systems
10 July 2013
Policies that improve the energy efficiency of urban transport systems could help save as much as USD 70 trillion in spending on vehicles, fuel and transportation infrastructure between now and 2050, according to a new report from the International Energy Agency.
The report, A Tale of Renewed Cities, draws on examples from more than 30 cities across the globe to show how to improve transport efficiency through better urban planning and travel demand management. Extra benefits include lower greenhouse-gas emissions and higher quality of life.
The report comes at a critical time: More than half of the world’s population already lives in cities, many of which suffer from traffic jams and overcrowded roads that cost hundreds of billions of dollars in lost fuel and time and that harm environmental quality, health and safety.
“As the share of the world’s population living in cities grows to nearly 70 percent by 2050 and energy consumption for transport in cities is expected to double, the need for efficient, affordable, safe and high-capacity transport solutions will become more acute,” said IEA Executive Director Maria van der Hoeven as she presented the report. “Urgent steps to improve the efficiency of urban transport systems are needed not only for energy security reasons, but also to mitigate the numerous negative climate, noise, air pollution, congestion and economic impacts of rising urban transport volumes.”
She urged policy makers to take a systems perspective and a long-term view to address the challenges. “Governments must think beyond individual technologies and electoral cycles, and consider how to build – and how to renew – cities that will accommodate and transport nearly 6.3 billion people by 2050. We must plan infrastructure, logistics and energy systems now that make sense today and over the coming decades,” she said.
Among the three broad categories of policies recommended in the report are those that allow travel to be avoided, those that shift travel to more efficient modes, and those that improve the efficiency of vehicle and fuel technologies. The report notes that if fully implemented across the transportation sector, this “avoid, shift and improve” approach could save up to USD 70 trillion in terms of lower spending on oil, roadway infrastructure and vehicles.
The report offers three case studies – Belgrade, Seoul and New York City -- to show how those cities have already improved their transport systems. It notes, for example, that within the first six months of refurbishing its urban rail system, Belgrade tripled passenger levels. When Seoul pushed through reforms that no longer rewarded bus operators for carrying more people, ridership, speed and safety all increased. And New York City shaved 11 minutes off travel times within a year of introducing express bus services, while at the same time attracting more passengers.
A Tale of Renewed Cities, which was supported by the European Bank for Reconstruction and Development, sets forth a pathway outlining the essential steps and milestones for policy development and implementation to transform cities by improving urban transport systems. The pathway is divided into four sections that present the necessary planning and actions for supporting development, financing, implementation and evaluation of policies to improve the energy efficiency of urban transport systems.
To assist planners and policy makers in addressing many common issues and challenges, the pathway also provides a list of policy references and practitioner's guides that are noted throughout the report and on the IEA Policy Pathway Series webpage.
The International Energy Agency is an autonomous organisation which works to ensure reliable, affordable and clean energy for its 28 member countries and beyond. Founded in response to the 1973/4 oil crisis, the IEA’s initial role was to help countries co-ordinate a collective response to major disruptions in oil supply through the release of emergency oil stocks to the markets. While this continues to be a key aspect of its work, the IEA has evolved and expanded. It is at the heart of global dialogue on energy, providing reliable and unbiased research, statistics, analysis and recommendations.
