Science, Technology, and Public Policy

A new study co-authored by researchers at Harvard Kennedy School's Belfer Center for Science and International Affairs, Duke University’s Nicholas Institute for Environmental Policy Solutions, and the University of Calgary provides the first comprehensive representation of changing water consumption patterns associated with fuel extraction and power generation.

For the past forty years, United States Presidents have repeatedly called for a reduction in the country's dependence on fossil fuels in general and foreign oil specifically. Some officials advocate the electrification of the passenger vehicle fleet as a path to meeting this goal. The Obama administration has embraced a goal of having one million electric-powered vehicles on U.S. roads by 2015, while others proposed a medium-term goal where electric vehicles would consist of 20% of the passenger vehicle fleet by 2030 — approximately 30 million electric vehicles. The technology itself is not in question; many of the global automobile companies are planning to sell plug-in hybrid electric vehicles (PHEVs) and/or battery electric vehicles (BEVs) by 2012. The key question is, will Americans buy them?

John P. Holdren, President Obama's chief science and technology advisor, draws a grim picture of our world at the end of this century if we fail to start slashing greenhouse gas emissions that are ravaging the global climate. In a lecture at MIT, Holdren issued a call to action, arguing for a package of integrated measures to protect the environment. Holdren is on leave from Harvard Kennedy School's Belfer Center, where he was director of the Science and Technology Public Policy program.

"...[S]ince sanctions and economic constraints will directly impact ordinary Iranians, they will intensify the current sense of distrust towards the West and especially the United States in all political trends and people, subsequently resulting in national mobilization and unity, thereby strengthening the hand of the Iranian government to resist the sanctions. This is the complete opposite of the result desired by the West."

CAMBRIDGE, Mass. — A new study from current and former researchers at Harvard Kennedy School's Belfer Center for Science and International Affairs finds that reducing greenhouse gas emissions from transportation will be a much bigger challenge than conventional wisdom assumes — requiring substantially higher fuel prices combined with more stringent regulation.

This policy brief is based on Belfer Center paper #2010-02 and an article published in Energy Policy, Vol. 38, No. 3.

Oil security and the threat of climate disruption have focused attention on the transportation sector, which consumes 70% of the oil used in the United States.
This study explores several policy scenarios for reducing oil imports and greenhouse gas emissions from transportation.
