Removing Carbon Dioxide Through Ocean Alkalinity Enhancement And Seaweed Cultivation: Legal Challenges And Opportunities, Romany M. Webb, Korey Silverman-Roati, Michael B. Gerrard

Faculty Scholarship

This paper explores two ocean-based carbon dioxide removal strategies – ocean alkalinity enhancement and seaweed cultivation. Ocean alkalinity enhancement involves adding alkalinity to ocean waters, either by discharging alkaline rocks or through an electrochemical process, which increases ocean pH levels and thereby enables greater uptake of carbon dioxide, as well as reducing the adverse impacts of ocean acidification. Seaweed cultivation involves the growing of kelp and other macroalgae to store carbon in biomass, which can then either be used to replace more greenhouse gas-intensive products or sequestered.

This paper also examines the international and U.S. legal frameworks that apply to …

Presidential Progress On Climate Change: Will The Courts Interfere With What Needs To Be Done To Save Our Planet?, Michael B. Gerrard

Faculty Scholarship

The Biden Administration is undertaking numerous actions to reduce greenhouse gas emissions and transition away from fossil fuels as part of the fight against climate change. Many of these actions are likely to be challenged in court. This paper describes the various legal theories that are likely to be used in these challenges, assesses their prospects of success given the current composition of the Supreme Court, and suggests ways to minimize the risks.

The Legal Framework For Offshore Carbon Capture And Storage In Canada, Romany M. Webb, Michael B. Gerrard

Faculty Scholarship

Averting catastrophic climate change requires immediate action to prevent additional carbon dioxide and other greenhouse gases being released into the atmosphere. However, even that may not be sufficient, with many scientists now warning that it will likely also be necessary to reduce the existing atmospheric carbon dioxide load. That could be achieved using negative emissions technologies that remove carbon dioxide from the atmosphere and store or utilize it in some way. One promising technology is direct air capture (“DAC”) which uses liquid chemical solutions or solid sorbent filters to capture carbon dioxide from the air and concentrate it into a …
