Fig. 2: Carbon feedstock sources pathways for primary chemical production.

a Carbon feedstock in energy terms. b Carbon feedstock in mass terms. Supplementary Figs. 13 and 14 show the regional pathways for biogenic storage in biomaterials and primary biomass use across R5 regions, respectively. While Asia and the OECD90 + EU have similar biomass use pathways, the Asian R5 region uses up to three times more for non-energy purposes based on the biogenic carbon storage results compared to the OECD90 + EU by 2050. EJ exajoules, NPi Implemented National Policies; 1.5C: carbon budget consistent with limiting global warming to 1.5 °C; gCCS: a 1.5C scenario with restrictions on global CCS deployment, PBIO: a 1.5C scenario with constraints on global primary biomass use; MNEToff: a 1.5C scenario that turns off the assumption of biogenic carbon storage in materials; and all: a comprehensive 1.5C sensitivity scenario incorporating all the abovementioned restrictions.
