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?

The Spring 2011 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights the Belfer Center’s continuing efforts to build bridges between the United States and Russia to prevent nuclear catastrophe – an effort that began in the 1950s. This issue also features three new books by Center faculty that sharpen global debate on critical issues: God’s Century, by Monica Duffy Toft, The New Harvest by Calestous Juma, and The Future of Power, by Joseph S. Nye.

The Winter 2010/11 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights a major Belfer Center conference on technology and governance, the Center's involvement in the nuclear threat documentary Countdown to Zero, and a celebration of Belfer Center founder Paul Doty.

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.

The Summer 2010 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights the Belfer Center's involvement with the Nuclear Security Summit, which was organized by Center alumni Gary Samore and Laura Holgate.

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.

Even as the US debates an economy-wide CO2 cap-and-trade policy the transportation sector remains a significant oil security and climate change concern. Transportation alone consumes the majority of the US's imported oil and produces a third of total US Greenhouse-Gas (GHG) emissions. This study examines different sector-specific policy scenarios for reducing GHG emissions and oil consumption in the US transportation sector under economy-wide CO2 prices.

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 paper finds that reducing carbon dioxide emissions from the transportation sector 14% below 2005 levels by 2020 may require gas prices greater than $7/gallon by 2020. It also finds that while relying on subsidies for electric or hybrid vehicles is politically seductive, it is ineffective and extremely expensive.
