En-ROADS includes various carbon dioxide removal (CDR) approaches with the “Afforestation” and “Technological Carbon Removal” sliders. The “Technological Carbon Removal” slider encompasses direct air capture (DAC), agricultural sequestration methods, enhanced mineralization, and biochar. 

All of these approaches remove carbon from the air and should, in theory, result in a net reduction in carbon dioxide in the atmosphere. These approaches are at various levels of development and scale globally. Carbon capture and storage for coal and gas is another approach to storing carbon, although it is not included as a type of CDR in En-ROADS because it does not result in a net removal of carbon. 

You can also change the assumptions about carbon dioxide removal in En-ROADS. On the top menu, click Simulation and then Assumptions and scroll down to “Carbon dioxide removal maximum,” which allows you to see and change the assumptions about the potential for each CDR technology in terms of the maximum removal flux (Gt CO₂/year). 

To learn more about CDR in En-ROADS, read the User Guide section on the Technological Carbon Removal slider.
