Rejected 10 January 2024

The proposed methodology applies to project activities that utilize photoautotrophic microorganisms to capture and convert CO2 emissions from industrial facilities into bio-based materials, namely fertilizer and aquaculture feed. GHG emission reduction is achieved as CO2 emissions are digested by microorganisms and the biomass of these microorganisms is used as raw materials to produce less emission-intensive fertilizer or aquaculture feed. The proposed methodology is globally applicable.
