Direct air capture image: Direct air capture (DAC), like this seeing at the ClimateWorks facility, with storage (DACS) has the potential for billion tonne atmospheric carbon dioxide removal but will require concurrent buildout of energy resources.

Cover cropping has a relatively high potential contribution to national soil-based CO2-removal efforts due mainly to the large extent of land area that can be cover-cropped without interfering with cash-crop production. Cereal rye because it is by far the most widely planted cover crop currently in the United States.
