Support for carbon dioxide removal (CDR) is growing globally. Governments are, it seems, beginning to listen to the growing chorus of scientists who have warned that deploying CDR is essential to avoid catastrophic climate change. Government funding for research and deployment of CDR is increasing. Many governments are beginning to […]

By Korey Silverman-Roati Carbon dioxide removal (CDR) will be needed, alongside deep emissions cuts, to achieve global temperature goals. The Intergovernmental Panel on Climate Change (IPCC) has emphasized that, to limit warming to 1.5oC or 2oc, in line with the Paris Agreement, global carbon dioxide emissions must reach net-zero between […]
By Korey Silverman-Roati Growing interest in using the oceans to enhance removal of carbon dioxide from the atmosphere has in turn spurred more interest in seaweed cultivation. A recent report by the National Academies of Sciences, Engineering, and Medicine (NASEM) concluded that the “ocean holds great potential for uptake and longer-term sequestration […]
Despite scientists’ dire warnings about the impacts of climate change, the anthropogenic greenhouse gas emissions that cause it continue to increase. The atmospheric concentration of carbon dioxide—the most commonly emitted greenhouse gas—is now higher than at any time in at least the last 800,000 years and likely several million years. […]
In a report published last month, the Intergovernmental Panel on Climate Change (IPCC) warned that, to keep global average temperatures within 1.5oC above pre-industrial levels, greenhouse gas emissions must reach net zero by mid-century. According to the IPCC, to achieve net zero emissions, carbon dioxide removal (CDR) will be […]
By Korey Silverman-Roati and Romany M. Webb The Sabin Center today released the second in a series of white papers discussing legal issues associated with different ocean-based carbon dioxide removal techniques. Today’s paper focuses on seaweed cultivation—i.e., the growing of kelp and other macroalgae which may be harvested for food, […]
By Romany M. Webb and Korey Silverman-Roati Ocean alkalinity enhancement (OAE) is one of several proposed techniques for removing carbon dioxide from the atmosphere and storing it in the oceans. As a result of natural processes, the oceans have already absorbed around 30% of all carbon dioxide emitted by humans […]
This week’s IPCC report is another stark reminder of the need to dramatically reduce greenhouse gas emissions to avoid climate disaster. While the U.S. has started down the path of decarbonizing its economy, there remains significant work to do, and many challenges ahead. Some sectors, including certain heavy industries […]
