Even if CCUS is rolled out at scale, will there continue to be carbon dioxide emissions?

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.
