Legal Pathways to the Broad Use of Negative Emissions Technologies and Direct Air Capture of Greenhouse Gases
Deep decarbonization will have to explore the use of negative emissions technologies (NETs), which include the direct air capture (DAC) of ambient carbon dioxide. NETs capture or consume more carbon dioxide than they emit, and DAC is a subset of NETs that use any industrialized chemical or physical methods to remove greenhouse gases from the atmosphere and then store or reuse those gases, typically in a way that does not allow them to escape.
