To meet the net-zero carbon emission goals being set by countries and corporations around the world, large-scale deployment of negative emissions technologies (NETs) will likely be needed to offset recalcitrant and historic emissions. Integrated modeling efforts to date have focused on the global scale and suggest that we will need removal at a scale of gigatons CO2/year without considering the impact these emerging technologies could have on the regions where they will be deployed. Here we used the GCAM-USA integrated assessment model to analyze how a suite of NETs, direct air capture, bioenergy with carbon capture and storage (liquids and electricity), and land use change would be deployed across all fifty US states. Results suggest that, when national emissions are required to reach net-zero by 2050, NETs deployment across the US is significant but uneven across states. Certain factors, including potential to deploy carbon capture and storage at scale, are critical to supporting a major NETs industry at scale.
