based gasoline efficiency. For diesel fuel, the well-to-pump energy use for the process-level allocations with the mass- and energy-content-based weighting factors is smaller than that predicted with the refinery-level allocations. However, the process-level alloca-tion with the market-value-based weighting factors has results very close to those obtained by using the refinery-level alloca-tions. For LPG, the refinery-level allocation significantly overes-timates LPG energy use. For naphtha, the refinery-level alloca-tion overestimates naphtha energy use. The GHG emission patterns for each of the fuels are similar to those of energy use. Conclusions. We presented a refining-process-level-based method that can be used to allocate energy use of individual refining processes to refinery products. The process-level-based method captures process-dependent characteristics of fuel production within a petroleum refinery. The method starts with the mas
