Removing Methane from the Atmosphere: New Sabin Report on Atmospheric Methane Destruction via Oxidation Enhancement

Law Columbia

In addition to investigating new ways to control methane emissions, scientists are also researching the possibility of removing methane already in the atmosphere. Those issues are explored in a new report by researchers at the Sabin Center, Removing Methane via Atmospheric Oxidation Enhancement: The Legal Landscape.
