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, […]
Negative Emissions

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 […]
By Romany Webb Enhanced weathering is one of several proposed approaches for removing carbon dioxide from the Earth’s atmosphere. It aims to enhance natural weathering processes in which carbon dioxide in the atmosphere reacts with silicate-based rocks, eventually forming carbonate minerals (e.g., limestone). Research suggests that the natural processes can […]
In October 2019, the Sabin Center joined an international research project, assessing the feasibility of offshore carbon capture and storage. Known as Solid Carbon, the project is led by researchers at Ocean Networks Canada, a University of Victoria initiative, and supported by the Pacific Institute for Climate Solutions under its […]
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 […]
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 […]
By Romany Webb It is well known that, to avoid the worst impacts of climate change, we must reduce the amount of carbon dioxide entering the atmosphere. Most carbon dioxide emissions result from the burning of fossil fuels – i.e., coal, oil, and natural gas – in electricity generation, transport, […]
