Carbon Dioxide Removal Deployment Consistent with Global Climate Objectives

Abstract The IPCC 6th Assessment Report lacked sufficient land sector scenario information to estimate total carbon dioxide removal (CDR) deployment. Using a new dataset, we show that land CDR plays an important near-term role and novel removal technologies scale to multi-gigatonne levels by 2050 and beyond to balance residual emissions and draw down warming. Reducing fossil fuel and deforestation emissions accounts for over 80% of net greenhouse gas reductions until global net zero CO2 independent of climate objective stringency.
