Improvements in eco-efficiency—defined as a combination of reducing waste and reducing the use of raw inputs—offer one strategy for reducing greenhouse gas emissions while also lowering production costs. In addition, changes in culture—at the level of individual businesses, countries, or both—can enhance the eco-competitive position of these businesses and countries. This paper describes three examples from Costa Rica and shows how the goal of achieving carbon neutrality can provide incentives for improving eco-efficiency and eco-competitiveness.

"Irregular migration has great resonance in the Gulf, just as in the West. Migrants in irregular situation avoid state administrative procedures and so their numbers are unknown. The largest amnesty (Saudi Arabia 2013) would have affected more than 50 per cent of the migrants in the country. Irregular migration is by definition a breach of legislations that regulate the migrant’s status.
In the Gulf States it is, in particular, a by-product of: the sponsorship (kafâla) system that hampers both a migrant’s individual freedom of movement and the free functioning of the labour market; nationalisation policies that continue to extend the list of occupations reserved for nationals; and nationality laws that bar citizenship to all but a very few first- and second-generation migrants."
Plants draw carbon dioxide from the atmosphere as they grow, sequestering the carbon in biomass and thus helping to mitigate climate change. This mitigation has an economic value commensurate with reduced damages from climate change. However, the U.S. National Park Service (NPS) has not calculated the carbon-sequestration benefits provided by the 84 million acres of land it manages, even though 85% of this land is vegetated.
The NPS has a dual mission—to foster both tourism ("visitation" to those researching this topic) and land stewardship. Measuring the value of carbon sequestration would complement ongoing attempts to measure the economic value of tourism by providing an initial estimate of the economic importance of one component of the NPS's stewardship obligations.
"The Role of Border Carbon Adjustment in Unilateral Climate Policy: Insights from a Model-Comparison Study—Summary"
In the absence of an effective global agreement to reduce carbon emissions, some industrialized countries have taken unilateral action to reduce emissions. However, unilateral carbon policy can lead to leakage of carbon emissions and precludes abating emissions where such abatement would be least expensive (possibly in other countries). Border carbon adjustment (BCA) is one policy option to mitigate these two disadvantages of unilateral action, but the effectiveness of these measures remains unclear. Comparing the results of simulated carbon policy and BCA in multiple computable general equilibrium (CGE) models of the global economy offers several estimates of the effectiveness of BCA.

A grand bargain would not constitute the entirety of U.S. policy toward China. Unilateral measures and alliances would remain essential components of U.S. policy. When uncertain about a state's motives and goals, a state should pursue a mix of cooperative and competitive policies.

The July 14, 2015 comprehensive nuclear deal between Iran and the P5+1 (known as the Joint Comprehensive Plan of Action or JCPOA) consists of the agreement itself and five technical annexes: Annex I – Nuclear-related measures; Annex 2 – Sanctions-related commitments; Annex III- Civil Nuclear Cooperation; Annex IV – Joint Commission; and Annex V – Implementation Plan. The version issued by the EU is used here because pages and paragraphs are numbered in proper order.
This article describes the main elements of the JCPOA. In coming days, the Belfer Center plans to publish a more detailed description and assessment of the agreement.

Recent research in economics shows how not to design climate treaties—and suggests how to get it right.
Emitting carbon dioxide (CO2 )—and other greenhouse gases—imposes a cost on society because it contributes to damages from climate change. This "social cost" is also known as an "externality," in that the emitter does not bear this cost. The "Social Cost of Carbon" (SCC), then, is the "marginal monetized externality value" of damages from CO2 emissions, where "marginal" refers to the next incremental unit of emissions. As damages from climate change become more evident, it becomes increasingly useful in formulating public policy (especially in connection with attendant benefit-cost analysis of that policy) to employ an SCC—that is, a numerical, non-zero value for climate damages. This paper examines the process in the U.S. government of specifying an SCC.

The United States and Russia are the two countries with the vast majority of the world's nuclear weapons and material. In an age of global terrorism, they share both a special responsibility in ensuring that they each employ effective nuclear security systems and an understanding of the unique challenge of securing hundreds of tons of nuclear material. For two decades, the United States and Russia lived up to this responsibility by working together to strengthen nuclear security in Russia and around the globe. That ended in 2014 when Russia halted the majority of its work on nuclear security with the United States. The negative consequences of that decision could seriously affect international security and cooperation in the nuclear realm.

This April, the United States assumed the Chairmanship of the Arctic Council. The Belfer Center Environment and Natural Resources Program is releasing a series of policy briefs on the issues relating to the Arctic. This brief, focusing on security issues, is the first in this series.
