The current scenarios, however, are criticized because they feature strategies with pronounced overshoot of the global temperature goal, requiring a long-term repair phase to draw temperatures down again through net-negative emissions. Some impacts might not be reversible. Hence, we explore a new set of net-zero CO2 emissions scenarios with limited overshoot. We show that upfront investments are needed in the near term for limiting temperature overshoot but that these would bring long-term economic gains. Our study further identifies alternative configurations of net-zero CO2 emissions systems and the roles of different sectors and regions for balancing sources and sinks. Even without net-negative emissions, CO2 removal is important for accelerating near-term reductions and for providing an anthropogenic sink that can offset the residual emissions in sectors that are hard to abate. 2021-11-29 published Nature Publishing Group 10.1038/s41558-021-01215-2 250 130 254 64 94 97 2881 166 114 3104 3194 3102 3099 public Nature Climate Change 11 1063-1069 TRUE 1758-678X Exploring National and Global Actions to reduce Greenhouse gas Emissions (ENGAGE, H2020 821471) yes info:eu-repo/grantAgreement/EC/H2020/821471/EU//ENGAGE info:eu-repo/semantics/article info:eu-repo/semantics/openAccess
