It’s called CDR – Carbon Dioxide Removal, and this free article:
Quote from abstract: << Parties to the UNFCCC and Paris Agreement have agreed to pursue efforts to limit the global average temperature increase to 1.5°C. To meet this goal, the international community will have to aggressively reduce emissions and also remove CO2 from the atmosphere on an unprecedented scale, through an array of biological and technical Carbon Dioxide Removal (CDR) options. This paper considers governance challenges that arise from the need to rely on CDR to meet the Paris Agreement’s long-term temperature goal. It looks at how heavy this reliance may have to be, over what timeframe, involving what options and, crucially, how best to ensure that CDR does not, while trying to address one problem, create many other challenges for sustainable development.

Quote from introduction: << The resulting IPCC Special Report on Global Warming of 1.5°C (IPCC SR 1.5°C) makes clear that it will not be sufficient for the international community to merely reduce emissions to limit temperature increase to below 1.5° C; CO2 will have to be removed from the atmosphere on a substantial scale, through biological and technological means – through options that have been collectively termed carbon dioxide removal or ‘CDR’. The Report also makes clear that failure to get the world on a 1.5°C-consistent pathway will result in irreversible impacts on human, social, ecological and economic systems. >>
