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, bioenergy, or other uses or […]

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 since the start of the […]

By Romany M. Webb 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 and freight […]

Achieving the Paris Agreement’s goal of limiting warming to “well below” 2oC above pre-industrial levels will require an immediate and dramatic reduction in greenhouse gas emissions which must reach “net zero” around mid-century. This will likely necessitate the use of so-called “negative emissions technologies” that can remove greenhouse gases from the atmosphere to offset emissions […]

By Romany Webb Despite scientists’ dire warnings about the catastrophic impacts of climate change, the greenhouse gases that cause it continue to be emitted in substantial amounts. There is no question that deep, across the board cuts in greenhouse gas emissions are essential, but many scientists now agree that simply cutting future emissions will not […]
