Accounting for terrestrial and marine carbon sink enhancement

 Marius Paschen,  Felix Meier,  Wilfried Rickels

Abstract

Any integration of extra carbon dioxide removal (CDR) via terrestrial or marine sink enhancement into climate policies requires accounting for their effectiveness in reducing atmospheric carbon concentration and translating this information into the amount of carbon credits (to be used in official and voluntary emission trading schemes). Here, we assess accounting schemes in their appropriateness of assigning carbon credits. We discuss the role of temporary carbon storage and present the various accounting methods for carbon credit assignment. We explain how we have implemented the methods numerically and analyse carbon assignments across the different accounting schemes, using stylized, model-based ocean sink enhancement experiments.

For each gigawatt (GW) of continuous electric power generated over one year by negative-emissions OTEC (NEOTEC), roughly 13 GW of surface ocean heat would be directly removed to deep water.
