Belfer Center for Science and International Affairs, Harvard University
Abstract:
Today, as a species, we face two existential threats: nuclear annihilation and catastrophic climate change. Both stem from human origins. We need to fight both threats aggressively. There are many things we can and should do to tackle the climate threat, beginning with putting a price on carbon emissions, promoting market mechanisms that reward efficiency, leveling the playing field for all lower-carbon energy sources, and leveraging the Paris Climate Agreement into more effective international action. But even adding up all existing national commitments to curtail greenhouse gas emissions, and assuming perfect execution, the world falls far short of the cuts needed to avoid catastrophic climate change. The expanded use of nuclear energy can make a major contribution to closing that gap and meeting our climate goals. But inherent in the use of atomic fission is the risk that the technology and materials can be diverted to terrorists or hostile nations.

4. Assessing Future Water Availability in Arid Regions Using Composition and Salience of Decision Criteria

Abstract:
Water resources development options are usually selected on a least-cost basis. While economic considerations are dominant in choosing projects, there are also a mix of other factors including social demands, political expediency, social equity, and environmental considerations that impact final decisions and development of water supply systems. Understanding local priorities in water resource management decisions can allow for forming expectations of future regional water availability. In this research, we propose that future water availability in arid regions may be assessed by considering key projects that have been identified or planned by regional experts. Using Multi-Criteria Decision Analysis methods as a framework to organize set of decision criteria and their relative salience, the likelihood of selection (and development) of a project can be determined and used to form expectations of future regional water availability. We use this approach in a case study for Jordan, and find that large-scale desalination projects–that have been in the planning books for decades-are now most likely to be pursued and implemented in the country. Finally, we discuss strengths, limitations, and the general applicability of this method for assessing future water availability in other arid regions.

5. A Pre-Lima Scorecard for Evaluating which Countries are Doing Their Fair Share in Pledged Carbon Cuts

Author:

Publication Date:

Content Type:
Policy Brief
Institution:
Belfer Center for Science and International Affairs, Harvard University
Abstract:
Those worried about the future of the earth's climate are hoping that the climate change convention in Lima, Peru, in December 2014, will yield progress toward specific national commitments to reduce greenhouse-gas (GHG) emissions. The Lima conference will be hosted by the United Nations Framework Convention on Climate Change (UNFCCC) and is a prelude to the make-or-break Paris meeting of the UNFCCC, in December 2015, where a new international agreement is scheduled to be concluded.

6. Climate Negotiations Open a Window: Key Implications of the Durban Platform for Enhanced Action

Author:
Robert N. Stavins and Joseph E. Aldy

Content Type:
Policy Brief
Institution:
Belfer Center for Science and International Affairs, Harvard University
Abstract:
A key outcome of the Seventeenth Conference of the Parties (COP-17) of the United Nations Framework Convention on Climate Change (UNFCCC), held in Durban, South Africa, late in 2011 — the Durban Platform for Enhanced Action — represents an important milestone in the history of climate negotiations. This is because it departs from the long-standing and problematic dichotomous division of the world's countries into those with serious emissions-reduction responsibilities and the others — with no such responsibilities whatsoever. That distinction, now apparently abandoned, has prevented meaningful progress for decades. The Durban Platform — by replacing the Berlin Mandate's (1995) division of the world into a set of countries with ambitious responsibilities and another set of countries with no responsibilities — has opened an important window. National delegations from around the world now have a challenging task before them: to identify a new international climate policy architecture that is consistent with the process, pathway, and principles laid out in the Durban Platform, while still being consistent with the UNFCCC. The challenge is to find a way to include all key countries in a structure that brings about meaningful emission reduction on an appropriate timetable at acceptable cost, while recognizing the different circumstances of countries in a way that is more subtle, more sophisticated, and — most important — more effective than the dichotomous distinction of years past.

7. The SO2 Allowance Trading System: The Ironic History of a Grand Policy Experiment

Author:
Robert N. Stavins and Richard Schmalensee
Publication Date:

Content Type:
Working Paper
Institution:
Belfer Center for Science and International Affairs, Harvard University
Abstract:
Two decades have passed since the Clean Air Act Amendments of 1990 launched a grand experiment in market-based environmental policy: the SO2 cap-and-trade system. That system performed well but created four striking ironies. First, by creating this system to reduce SO2 emissions to curb acid rain, the government did the right thing for the wrong reason. Second, a substantial source of this system's cost-effectiveness was an unanticipated consequence of earlier railroad deregulation. Third, it is ironic that cap-and-trade has come to be demonized by conservative politicians in recent years, since this market-based, cost-effective policy innovation was initially championed and implemented by Republican administrations. Fourth, court decisions and subsequent regulatory responses have led to the collapse of the SO2 market, demonstrating that what the government gives, the government can take away.

8. International Paretianism: A Defense

Author:

Content Type:
Working Paper

Belfer Center for Science and International Affairs, Harvard University
Abstract:
A treaty satisfies what we call International Paretianism if it advances the interests of all states that join it, so that no state is made worse off. The principle might seem obvious, but it rules out nearly all the major proposals for a climate treaty, including proposals advanced by academics and by government officials. We defend International Paretianism, and for that reason urge commentators in the debate over climate justice to abandon efforts to right past wrongs, redistribute wealth, and achieve other abstract ideals through a climate treaty.

9. Post-Durban Climate Policy Architecture Based on Linkage of Cap-and-Trade Systems

Author:
Robert N. Stavins

Content Type:
Working Paper
Institution:
Belfer Center for Science and International Affairs, Harvard University
Abstract:
The outcome of the December 2011 United Nations climate negotiations in Durban, South Africa, provides an important new opportunity to move toward an international climate policy architecture that is capable of delivering broad international participation and significant global CO2 emissions reductions at reasonable cost. We evaluate one important component of potential climate policy architecture for the post-Durban era: links among independent tradable permit systems for greenhouse gases. Because linkage reduces the cost of achieving given targets, there is tremendous pressure to link existing and planned cap-and-trade systems, and in fact, a number of links already or will soon exist. We draw on recent political and economic experience with linkage to evaluate potential roles that linkage may play in post-Durban international climate policy, both in a near-term, de facto architecture of indirect links between regional, national, and sub-national cap-and-trade systems, and in longer-term, more comprehensive bottom-up architecture of direct links. Although linkage will certainly help to reduce long-term abatement costs, it may also serve as an effective mechanism for building institutional and political structure to support a future climate agreement.

10. What are the Welfare Costs of Shoreline Loss? Housing Market Evidence from a Discontinuity Matching Design

Author:
Matthew Ranson

Working Paper

Abstract:
This paper uses housing market data to estimate the welfare costs of shoreline loss along coastal beaches in Florida. I develop a forward-looking structural model of a housing market in which a time-variant housing characteristic (beach width) follows a Markov process. I use this model to provide an exact welfare interpretation for the coefficients from three empirical research designs: (1) a repeat-sales panel regression of housing prices on beach width; (2) a differences-in-differences approach based on sharp changes in beach width caused by beach nourishment projects; and (3) a new “discontinuity matching” research design that exploits capitalized housing price differentials created by predictable changes in future beach width. Using a unique panel dataset on housing sales, beach width survey measurements, and the timing of 204 beach nourishment projects along 300 miles of Florida's coastline, I then use each of these research designs to estimate homeowners' willingness to pay for an extra foot of sand. In contrast to previous work, I find that changes in beach width have little impact on housing prices, except possibly at very eroded beaches. The results imply that the welfare costs of sea level rise may be low up to a threshold, and then increase sharply.
