title = "The influence of negative emission technologies and technology policies on the optimal climate mitigation portfolio",
abstract = "Combining policies to remove carbon dioxide (CO 2) from the atmosphere with policies to reduce emissions could decrease CO 2 concentrations faster than possible via natural processes. We model the optimal selection of a dynamic portfolio of abatement, research and development (R&D), and negative emission policies under an exogenous CO 2 constraint and with stochastic technological change. We find that near-term abatement is not sensitive to the availability of R&D policies, but the anticipated availability of negative emission strategies can reduce the near-term abatement optimally undertaken to meet 2°C temperature limits. Further, planning to deploy negative emission technologies shifts optimal R&D funding from {"}carbon-free{"} technologies into {"}emission intensity{"} technologies. Making negative emission strategies available enables an 80% reduction in the cost of keeping year 2100 CO 2 concentrations near their current level. However, negative emission strategies are less important if the possibility of tipping points rules out using late-century net negative emissions to temporarily overshoot the CO 2 constraint earlier in the century.",
