Ok, now I'm questioning your literacy. From the study:

"Methods To quantify the total food-related GHG emissions, we first estimated the total crop and grazing biomass, including livestock feed, and then partitioned the total biomass between plant- and animal-based food (livestock feed) and other utilizations.  Based on the estimated biomass, we calculated and partitioned the production-based GHG emissions from plant and livestock to plant- and animal-based food and other utilizations. After that, we calculated GHG emissions from the consumption-based perspective, taking into account transportation, international trade (import and export) and stock variation. We estimated the consumption-based emissions to explicitly account for the GHG emissions caused by trade. This was especially important for regions and countries which import and/or export large amounts of plant- and animal-based food in the context of better tracing food systems’ global and regional GHG footprints."

And it goes in. LCA is mentioned one time, and they mention the single methodology that they used.
