Science, Technology, and Public Policy

We here introduce the idea of highly decentralized solar geoengineering, plausibly done in form of small high-altitude balloons. While solar geoengineering has the potential to greatly reduce climate change, it has generally been conceived as centralized and state deployed. Potential highly decentralized deployment moves the activity from the already contested arena of state action to that of environmentally motivated nongovernmental organizations and individuals, which could disrupt international relations and pose novel challenges for technology and environmental policy. We explore its feasibility, political implications, and governance.

To assist Members of Congress and observers in analyzing these issues and judging a potential comprehensive agreement, the Belfer Center prepared this brief to outline the key facets of sanctions against Iran. Written as an addendum to our April policy brief, ‘Decoding the Iran Nuclear Deal,’ this report is driven by the policy debate’s leading questions.

On April 2, 2015, the E.U. (speaking on behalf of the P5+1 countries) and Iran announced agreement on “key parameters” for a comprehensive agreement on Iran’s nuclear program. The E.U.-Iran Joint Statement is buttressed by unilateral facts sheets issued by the U.S. and Iran, which provide further details of the framework accord. Negotiators now turn to translating this framework accord into a final comprehensive agreement by June 30, 2015. Members of Congress and their staffs, as well as informed citizens, are now focusing on the Iranian challenge and assessing the framework accord. The Belfer Center for Science and International Affairs at the Harvard Kennedy School has prepared this Policy Brief summarizing key facts, core concepts, and major arguments for and against the current deal aimed at stopping Iran from developing nuclear weapons. The purpose of this Policy Brief is not to advocate support for or opposition to the tentative deal that has been negotiated, but rather to provide an objective, nonpartisan summary to inform Members and others in coming to their own conclusions. The team of experts who prepared this report includes Democrats, Republicans, Independents, and internationals, who have many disagreements among themselves but who agree that this Brief presents the essentials objectively.

The unconventional fossil fuel extraction industry—in the U.S., primarily shale gas and tight oil—is expected to continue expanding dramatically in coming decades as conventionally recoverable reserves wane. At the global scale, a long-term domestic supply of natural gas is expected to yield environmental benefits over alternative sources of fossil energy. At the local level, however, the environmental impacts of shale gas and tight oil development may be significant. The development of technology, management practices, and regulatory policies that mitigate the associated environmental impacts of shale gas development is quickly becoming the next frontier in U.S. unconventional fossil resource extraction.

Working from a mandate from the 2010 Conference of the Parties to the UN Convention on Biological Diversity (CBD), this report compiles and synthesizes available scientific information on the possible impacts of geoengineering techniques on biodiversity, including preliminary information on associated social, economic, and cultural considerations.

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?

This paper proposes a framework for a liability regime for geological sites for sequestration of carbon dioxide. It incorporates issues that were discussed at the the June 21, 2010 Expert Workshop Addressing CCS Liability, Oversight, and Trust Fund Issues.

Harvard Law School’s Emmett Environmental Law and Policy Clinic* supports immediate large-scale carbon capture and sequestration (“CCS”) demonstration projects as part of a larger national and global effort to address climate change. Large-scale CCS projects (those that sequester at least 1.5 million tons of captured carbon dioxide (“CO2”) annually) must be demonstrated soon to confirm CCS as a viable strategy to combat climate change and to show the commitment of the United States to achieving meaningful reductions in domestic CO2 emissions.

This paper summarizes the discussions from a workshop convened by the Harvard Law School's Emmett Environmental Law & Policy Clinic in Washington, DC on June 21, 2010.

There is broad consensus in scientific, business, and political circles that carbon capture and sequestration ("CCS") must be demonstrated quickly on a large scale because it is likely to be an important technology for reducing carbon dioxide ("CO2") emissions throughout the world. Indeed, a number of commentators predict that it may be impossible to achieve significant emissions reduction in the United States and abroad without the use of CCS.
