Abstract

Growing evidence suggests that limiting global temperature increases to reasonably safe levels will require not only a rapid reduction in carbon dioxide (CO2) and other

greenhouse gas emissions (GHGs) around the world but large-scale removal of CO2 from the atmosphere as well. Every year that global emissions continue unabated, the required pace of future reductions accelerates, and the quantity of CO2 emissions that ultimately needs to be removed from the atmosphere grows. Fortunately, thanks to recent technological innovations, the options for CO2 removal are increasing in number and falling in cost. But significant policy action is required to ensure these technologies are available in time and at the scale required to avoid the worst impacts of global warming.

This report focuses on one of these emerging carbon removal technologies: Direct Air Capture (DAC). DAC safely removes CO2 from the air using chemical filters and produces a concentrated stream of CO2 for use in products like concrete and fuels or for permanent geologic storage. Carbon180, the Linden Trust for Conservation, and the ClimateWorks

Foundation asked Rhodium Group to conduct an independent analysis of the role DAC can play in supporting a decarbonized US future, its cost, and the actions required to achieve deployment at a scale that can have a global impact on reducing GHGs in the near, medium and long term.
