No Backing Down: The Role of Impermanent Carbon Dioxide Removal with Atmospheric Decay University of Kiel, Germany We study the optimal mitigation of CO2 emissions combined with the removal and storage of CO2 in an underground reservoir with leakage. The atmosphere consists of two virtual parts: A renewable and a non-renewable one. Although steady-state emissions converge to zero, we find that steady-state removal is positive and equal to the leaked emissions from the carbon storage. We analyze the comparative statics of the steady state with respect to decay, leakage, the discount rate, and the composition of the atmosphere. Furthermore, we analyze the dynamics of the optimal paths into the steady state using numerical simulations. We find that, while emissions converge monotonically to the steady state, the removal paths can be highly non-monotonic. In our calibrated model, integrating carbon dioxide removal partially substitutes emissions and results in a lower atmospheric carbon concentration, though, given current cost estimates, both effects are quantitatively relatively small. | |
