Question 1 of 30
AgriCorp, a large agricultural conglomerate, produces a primary crop, SoyPlus, and a byproduct, SoyMeal, during its soybean processing. SoyMeal is sold to a third-party animal feed manufacturer, replacing the need for them to produce a similar feed from virgin grains. AgriCorp is conducting a carbon footprint assessment of SoyPlus according to ISO 14067:2018. They need to decide on the most appropriate method for allocating the carbon emissions between SoyPlus and SoyMeal. Considering the principles of ISO 14067:2018 and the specific context of SoyMeal replacing virgin material production, which allocation method would provide the most accurate and environmentally meaningful carbon footprint for SoyPlus, reflecting the impact of SoyMeal on the overall carbon balance?
Employ system expansion, accounting for the avoided emissions from the third-party not having to produce virgin animal feed.
Use mass allocation, distributing the emissions based on the mass ratio of SoyPlus to SoyMeal produced.
Apply economic allocation, distributing the emissions based on the relative market value of SoyPlus and SoyMeal.
Ignore the byproduct entirely and allocate all emissions solely to SoyPlus, simplifying the assessment process.
