"Land-based carbon dioxide removal technologies under climate stabilization scenarios: implications and trade-offs"
by Gurgel, Angelo, Jennifer Morris, Sergey Paltsev, Bryan Mignone, Haroon Kheshgi and Howard Herzog

Carbon dioxide removal (CDR) technologies such as afforestation/reforestation and bioenergy with carbon capture and sequestration will be required to achieve climate stabilization goals and net zero pledges. Their deployment and GHG mitigation potential depend on regional characteristics and conditions, such as biomass and forest growth potentials and costs, land competition with other uses, decarbonization goals, and the extent of the climate policy coverage, if domestic or international. We assess the potential contribution of these CDR technologies as mitigation options under a global climate stabilization pathway. We enhance and deploy the MIT Economic and Projection and Policy Analysis model (EPPA) to represent regional and global CDR technologies and their competition for land. We find that these land intensive CDR options are both deployed and act more as complementary technologies, although some competition exists. Afforestation/reforestation can remove at most 8 Gt of CO2e per year by midcentury, while bioenergy with carbon capture and sequestration can reach 22 Gt/yr at the end of the century. The regional and temporal deployment of these CDR options are quite sensitive to the assumption of international trade in emissions permits, since few regions, such as Latin America and Africa, have comparative advantage in both CDRs.
