The United States needs to remove approximately 2 GtCO2 per year by 2050 to achieve climate neutrality, given that the U.S. Mid-century Strategy for Deep Decarbonization leaves roughly 2.55 GtCO2 of gross annual emissions unaddressed and land sinks are projected to decline. To reach this target, the document argues that an "all-of-the-above" portfolio—combining natural pathways like tree restoration and agricultural soil carbon with technological approaches like direct air capture—is the most effective, risk-averse, and cheapest strategy, yielding the highest cumulative carbon removal by 2050.
