GHG emission evaluation for derivatives. GHG emission calculation according to REDIII and RTFO methodology. The figure enables estimation of compliance with the GHG thresholds via a tree diagram. Arrows show the probability that the GHG reduction will be met and also give examples of emissions related to ammonia (carbon-free PtX product) and methanol (carbon-containing PtX product) production. Error bars visualize possible emission ranges, depending on the production concept (more information on the calculation of the bars and the upper and lower values of the error bar are given in thesupplemental information). Horizontal lines indicate GHG thresholds of the respective regulations. DAC, direct air capture; h.s., highest support threshold; MeOH, threshold for methanol.
