An Important New Report from the National Academies on Atmospheric Methane Removal

Last month, the National Academies of Sciences, Engineering, and Medicine (NASEM) released a report on a relatively new field of research – atmospheric methane removal. Addressing methane is critically important in addressing climate change – methane is the second largest contributor to human-driven warming after carbon dioxide. Although the concentration of […]

Upcoming Developments in International Governance of Marine Carbon Dioxide Removal

The next week has the potential to bring important developments for international governance of marine carbon dioxide removal (CDR). That’s because the parties to the London Convention and London Protocol are meeting from October 28 to November 1 in London to discuss, among other things, governance of ocean alkalinity enhancement […]

The Evolving Legal Landscape for Geologic Carbon Sequestration in the United States

  Geologic carbon sequestration—i.e., the storage of carbon dioxide in underground rock formations—has been the subject of much debate in recent years. Many see it as an important tool for combatting climate change. It is, after all, a necessary component of point-source carbon capture and storage (“CCS”) systems that seek […]

Removing Methane from the Atmosphere: New Sabin Report on Atmospheric Methane Destruction via Oxidation Enhancement

A highly potent greenhouse gas, methane makes a significant contribution to climate change, but has historically received relatively little attention in climate mitigation discussions. That is now beginning to change. In addition to investigating new ways to control methane emissions, scientists are also researching the possibility of removing methane already […]

The ITLOS Advisory Opinion and Marine Geoengineering: More Questions, Few Answers

On May 21, 2024, the International Tribunal for the Law of the Sea (ITLOS) released its long-awaited advisory opinion on climate change. The opinion was requested in 2022 by the Commission of Small Island States on Climate Change and International Law, which asked ITLOS to opine on States’ obligations to […]

The European Commission’s industrial carbon management strategy: ambitious and risky plans to achieve net-zero

In February, the European Commission published its highly anticipated industrial carbon management strategy. The document outlines the Commission’s plans to build an EU-wide carbon management infrastructure as part of its efforts to decarbonize the industrial sector and achieve negative emissions. This blog post discusses these plans by (i) looking at […]

Legal Issues in Oceanic Transport of Carbon Dioxide for Sequestration: Sabin Center Launches New Report

A new report published today by the Sabin Center examines the laws governing international transport of carbon dioxide for sequestration. We focus, specifically, on the shipping of carbon dioxide that was captured in Europe to the United States for sequestration there. Much of the report would also be relevant to […]

International Governance of Ocean-Based Carbon Dioxide Removal: Recent Developments and Future Directions

Ocean-based carbon dioxide removal (CDR) is attracting increased attention as a possible climate change response strategy. The Intergovernmental Panel on Climate Change (IPCC) has made clear that, while CDR cannot substitute for rapid and deep cuts in emissions, its use is “unavoidable” if the worst impacts of climate change are […]
