Removing Carbon Dioxide Through Artificial Upwelling And Downwelling: Legal Challenges And Opportunities, Romany M. Webb, Korey Silverman-Roati, Michael B. Gerrard

Faculty Scholarship

A 2022 report by the Intergovernmental Panel on Climate Change warned that, to keep global average temperatures within 1.5oC above pre-industrial levels, emissions must reach net-zero by mid-century. The report concluded that achieving net-zero emissions will require the removal of carbon dioxide from the atmosphere “to counterbalance hard-to-abate emissions” from sectors like agriculture, aviation, and shipping. The report further noted that, if deployed at large scales, carbon dioxide removal (“CDR”) could also be used to achieve net negative emissions and thus effectively reduce the atmospheric concentration of carbon dioxide.

A variety of CDR techniques, both terrestrial and ocean-based, have been …

Legal Pathways To Biden's Climate Goals, Michael B. Gerrard

Faculty Scholarship

Achieving President Biden’s goal of net-zero green­house gas emissions by 2050, with interim targets of being halfway there by 2030 and having entirely clean electric­ity by 2035, is possible with law and technologies that already exist or can be readily imagined. In the process, many more jobs would be created than lost, and aspects of the environment beyond climate change would be greatly improved. But it is a massive undertaking.

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 …
