Product system listed as an impact contributor
Posted: 28 Feb 2016 12:05
Hello,
I have run a calculation and am confused with the results. Looking at human toxicity for example, it lists the main contributors of the impacts in the pie chart. However, along with several impacting chemicals, my product system "crop production" is also included as an impact contributor, and is in fact the main contributor. So this means that the biggest human toxicity impact to producing crop x is the production of crop x -- this makes no sense!
I am assuming I have gone wrong somewhere -- anyone have any ideas? Any thoughts would be greatly appreciated.
(I am running ecoinvent 3.2 cutoff DB with openLCA 1.4.2.)
Thanks,
Geoff
