Legal scholar Andrey Todorov, Postdoctoral Research Fellow with the Arctic Initiative, reflects on the recent agreement reached by United Nations delegates to protect biodiversity in international waters and its implications for the Arctic. 

How can China make good on its pledge to reach carbon neutrality by 2060? In Foundations for a Low-Carbon Energy System in China, a team of experts from China and the United States explains how China's near-term climate and energy policies can affect long-term decarbonization pathways beyond 2030, building the foundations for a smoother and less costly national energy transformation.

Kelly Sims Gallagher asserts that politicians' pledges of dramatic long-term reductions should not let them off the hook for their failure to achieve more modest progress in the short term.

Joel Clement characterizes the growing greenhouse-gas emissions from the commercial shipping industry as well as the efforts of the United Nations body, the International Maritime Organization, to reduce these emissions as unacceptable.

Joel Clement outlines why he is vexed by global negligence with regards to investments in the fossil fuel industry.

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.

Every day that the EPA quietly ticks off another item, the social and financial consequences are being shifted from polluters to at-risk communities.

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.

The United States and Iran have engaged in a constant raising of the stakes as a means of securing leverage ahead of possible nuclear negotiations. This is a classic bargaining pattern but in the current context, such an approach is particularly risky due to the potential for misperceptions. The complexities of domestic and regional dynamics are also a factor. In such a situation, absent clear understanding of the other’s motivations and tactics, raising the stakes—rather than securing leverage for effective negotiations—could steer the United States and Iran towards a path toward war.

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.
