1 DRAFT DO NOT CITE OR QUOTE 11/13/17 4:18 PM Direct Air Capture of Greenhouse Gases Tracy Hester [Summary: Given the economy s ongoing reliance on fossil fuel energy sources and current high levels of anthropogenic greenhouse gases in the atmosphere, a full deep decarbonization pathway assessment should examine strategies using the Direct air Capture (DAC) of ambient carbon dioxide. DAC includes any industrialized and scalable method to remove greenhouse gases from the ambient atmosphere and either store or reuse those gases in a way that does not allow them to escape back into the atmosphere. While still nascent, these technologies include a wide array of approaches such as biomass energy with carbon Capture and sequestration, enhanced weathering of minerals, and the Direct mechanical Capture of ambient CO2 through filters and chemicals.]
4 ambient carbon dioxide. The Deep Decarbonization Pathways Project’s (DDPP’s) analysis does not discuss the viability and impact of this potential approach because
