Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Decarbonizing existing buildings is a key component of greenhouse gas emission reduction strategies, but private investors have been slow to finance residential decarbonization projects because of a range of barriers. Authors Chang, Fornara, and Sanghvi argue that green banks could play a major role in unlocking public and private financing for projects that are currently financially unviable. 

Direct air capture (DAC) is a type of technology that captures carbon dioxide directly from the air. As the negative impacts of climate change become ever more apparent, governments and private industries have funneled increasing support toward DAC as a critical pathway toward achieving a net-zero future. Although a promising technology, wide-scale deployment of DAC faces several significant challenges.

In late 2017, Mexico made headlines as Italian company Enel bid what was then a world-record low price for renewable energy in the country’s third such energy auction. This development was possible due to the historical and sweeping energy reforms passed with broad support in Mexico in 2013. Then-President Enrique Peña Nieto had succeeded where previous Mexican presidents had failed, reversing decades of resource nationalism and overhauling the energy sector through constitutional reforms that gave the private sector a larger role and advantaged renewable energy in Mexico’s economy. The 2017 auction seemed to indicate Mexico’s bright future not only as a conventional oil producer, but also as a clean energy power.

This discussion paper explores key areas of disagreement on Article 6 and explores possible outcomes from the upcoming Conference of the Parties to the United Nations Framework Convention on Climate Change (COP-26) in November 2021 in Glasgow.

Guangdong Province ranks first in economic output among China’s provinces and will play a major role in achieving China’s national climate-change goals. This paper examines the progress of Guangdong Province’s carbon dioxide emissions trading system (ETS) in reducing emissions; design features of the system; challenges it faces with regard to further development; and its relationship to China’s new national ETS.

In this report, we propose a market reform pathway for Yunnan that is both feasible and applicable to address some of these challenges immediately, while aiming for a standard design based on well-documented international experience. Our proposal includes at its heart a pay-for-performance monthly capacity auction that can help cover revenue deficiencies in the energy market. Building on international experience with capacity markets, this approach provides incentives for availability when generation is needed most and is compatible with the adoption of a single energy market for all electricity resources. Out-of-market payments to cover stranded costs of certain firms can thus be minimized. Finally, engaging consumers in both these energy and capacity markets can create high-powered incentives to shift consumption to low-cost months and hours, benefitting the entire province.

The United States and United Kingdom have longstanding traditions in use of environmental benefit-cost analysis (E-BCA). While there are similarities between how E-BCA is utilized, there are significant differences too, many of which mirror ongoing debates and recent developments in the literature on environmental and natural resource economics. We review the use of E-BCA in both countries across three themes: (a) the role of long-term discounting; (b) the estimation and use of carbon valuation; and, (c) the estimation and use of the value of a statistical life. 

This paper focuses on China and the potential role of renewable hydrogen in accelerating its transition to a low-carbon economy. Our research goal is to provide policymakers and other stakeholders the means to make informed decisions on technology innovation, policy instruments, and long-term investments in enabling infrastructure.

The seminal contributions of William Nordhaus to scholarship on the long-run macroeconomics of global climate change are clear. Much more challenging to identify are the impacts of Nordhaus and his research on public policy in this domain. The authors examine three conceptually distinct pathways for that influence: his personal participation in the policy world; his research’s direct contribution to the formulation and evaluation of public policy; and his research’s indirect role informing public policy
