I just followed the tutorial PC-PET bottle using openLCA V.2.1.0. I got the same result for the impact assessment of the PET production as the tutorial. But, when I start the project to compare PET, PC production, I got totally different relative results. My results showed that PET production has a higher (100%) impact on both GWP and human toxicity while the tutorial shows that PC has higher results (100%)!
