It is recognised that some residual emissions (i.e. emissions from sectors including agriculture and aviation that are not possible to completely remove) will remain in the atmosphere, unless CDR/GGR technologies like BECCS, DACCS and WECCS are deployed.
The IPCC and CCC LINK recognise the role of CCUS in limiting global warming to 1.5°C and achieving removal of historical and ongoing emissions, eventually reducing to 1990s levels.
