Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

Due Process Is in the Details: U.S. Targeted Economic Sanctions and International Human Rights Law

| 2019

The United States has employed targeted sanctions—economic and travel restrictions imposed directly on natural and legal persons—in a wide range of policy areas in the past two decades.  A substantial literature has considered the compatibility with international human rights law of the targeted sanctions practices of other actors, particularly the UN Security Council and the European Union. But relatively few scholars have examined U.S. targeted sanctions practices from that perspective. This essay argues that in principle, current U.S. designation practices can be reconciled with international standards.

A Process for Capturing CO2 from the Atmosphere

    Authors:

| 2018

The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.

Negotiating the "Iran Talks" in Tehran: The Iranian Drivers that Shaped the Joint Comprehensive Plan of Action

| Forthcoming

When Iran and the world powers resumed negotiations over Tehran's controversial nuclear program after a seven-year lull, Iran's hardline President Mahmoud Ahmadinejad was approaching the end of his second and last term. During that time, little progress was made. After the election of the moderate Hassan Rouhani to the presidency, the talks resumed decisively. Rouhani and his team were in an ideal position to strike a deal, as they were afforded cross-party support supplying them with political will and political capital.

Sanctions and export deflection: evidence from Iran

| Apr. 12, 2017

Do export sanctions cause export deflection? Data on Iranian non-oil exporters between January 2006 and June 2011 shows that two-thirds of these exports were deflected to non-sanctioning countries after sanctions were imposed in 2008, and that at this time aggregate exports actually increased. Exporting firms reduced prices and increased quantities when exporting to a new destination, however, and suffered welfare losses as a result.

Energy decisions reframed as justice and ethical concerns

| 6 May 2016

Many energy consumers, and even analysts and policymakers, confront and frame energy and climate risks in a moral vacuum, rarely incorporating broader social justice concerns. Here, to remedy this gap, we investigate how concepts from justice and ethics can inform energy decision-making by reframing five energy problems — nuclear waste, involuntary resettlement, energy pollution, energy poverty and climate change — as pressing justice concerns.
