In theory, there are two ways to address rising levels of GHGs in the atmosphere. We can reduce the creation of new GHGs (abatement) and increase the removal of existing ones (removal). In the context of SBTi net zero, as companies achieve their net zero targets, which are at least 90% reduced emissions for most sectors, they will need to neutralize their remaining emissions with removals.

The IPCC has a taxonomy of carbon dioxide removals which includes both technological removals and nature-based solutions.

  • NCS: natural climate solutions

  • BECCS: bioenergy with carbon capture and storage

  • DACS: direct air capture

  • CDR: carbon dioxide removal
