This report summarizes a workshop co-hosted by the Arctic Initiative and the Science and Technology Directorate of the U.S. Department of Homeland Security (DHS), focused on the challenges posed by the impacts of rapid climate change in Alaska.

North America continues to face evolving challenges to comprehensive emergency management. As climate change, technology, global health, and the nature and scale of emergencies change, so does the need for improved coordination among the United States, Mexico, and Canada. This is further complicated by the distinct federal systems that operate in each country, and the different roles that national, regional, and private corporations can and should play across all of these separate jurisdictions.

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.

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 considers the treatment of co-benefits in benefit-cost analysis of federal air quality regulations. Using a comprehensive data set on all major Clean Air Act rules issued by the Environmental Protection Agency over the period 1997–2019, the authors show that (1) co-benefits make up a significant share of the monetized benefits; (2) among the categories of co-benefits, those associated with reductions in fine particulate matter are the most significant; and (3) co-benefits have been pivotal to the quantified net benefit calculation in nearly half of cases.

This essay makes three arguments. First, the US government will need to establish a coronavirus commission, similar to the 9/11 commission, to determine why, since April 2020, the United States has suffered more coronavirus fatalities than any other country in the world. Second, the COVID-19 pandemic represents a watershed for what will be a major national security theme this century: biological threats, both from naturally occurring pathogens and from synthesized biology. Third, intelligence about globalized challenges, such as pandemics, needs to be dramatically reconceptualized, stripping away outmoded levels of secrecy.

To accelerate the global transition to a low-carbon economy, all energy systems and sectors must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, renewable hydrogen is drawing increased attention today as a versatile and sustainable energy carrier with the potential to play an important piece in the carbon-free energy puzzle. Countries around the world are piloting new projects and policies, yet adopting hydrogen at scale will require innovating along the value chains; scaling technologies while significantly reducing costs; deploying enabling infrastructure; and defining appropriate national and international policies and market structures.

What are the general principles of how renewable hydrogen may reshape the structure of global energy markets? What are the likely geopolitical consequences such changes would cause? A deeper understanding of these nascent dynamics will allow policy makers and corporate investors to better navigate the challenges and maximize the opportunities that decarbonization will bring, without falling into the inefficient behaviors of the past.

This discussion paper (available in English and Chinese) describes the evolution of decentralization over the reform period that began in China in 1978, different theories of institutional change in China, and how the empirical and theoretical literatures help scholars and policymakers understand the development of institutions for governing GHG-emitting activities.

In this report, the authors conduct a benchmarking analysis for energy and CO2 emissions intensity of the steel industry among the largest steel-producing countries.

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.
