Overview of all potential routes that connect the three feedstocks (slate: fossil; green: biomass; yellow: CO2) with the product side. All processes are graded on their sustainability in a three‐color scheme. The colors are based on the grading as in Table 4 (red:<2; yellow:<4, green:>4) The arrow style indicates the maturity of the process. Fossil pathways were kept separate from biomass and CO2 pathways.
