By 2050, the share of global GHG emissions attributed to chemicals has changed: emissions are abated by new supply technologies and now contribute only 15-24% of lifecycle emissions in the ME pathways (remaining residues due to CCS) and 0-2% in the NFAX/NFS pathways. Usephase emissions of fertilizers cannot be abated fully and contribute the largest share of positive emissions in each pathway in 2050 (27-52%) . However, the NFAX and NFS pathways have negative emissions contributions from biomass and DAC, enabling an overall net-negative emissions profile and compensating for the unabated fertilizer use-phase emissions. For example, olefins production today depends heavily on naphtha and ethane for steam cracking. A switch to bio-oils and bioethanol dehydration renders emissions for feedstock production negative for olefins production, up to 0.2 GtCO2eq removed every year.
