GHGs are continuously removed from the atmosphere through natural processes of carbon sequestration and storage. In particular, photosynthesis in trees, plants and algae absorbs CO2 from the air and converts it into other carbon compounds. These end up in biomass (e.g. tree trunks, branches, and roots) and soils, which serve as natural carbon sinks.
GHGs are removed from the atmosphere when:
- Natural carbon sinks are planted, grown or otherwise created;
- Existing natural carbon sinks are enhanced to absorb and store more carbon; or
- GHGs are removed from the atmosphere by technological means, and either used or stored in a way that prevents future emission.
This Positive Pursuit encompasses any action which achieves such an outcome.
