What does the unit Pt mean in terms of land use?

Question

I have made an LCA for a frozen pizza (320g), similar to your example on Youtube: https://www.youtube.com/watch?v=q8kCU8iiIEM&t=893s. What does Pt mean in the Contribution tree tab/impact category "land use"? And is 79.28 Pt plausible for 1 pizza?

Hello CP,

The pt measurement is a dimensionless measurement used in many LCIA methods. In most cases it comes from the LANCA model, which measured soil quality. Please read the attached documentation: https://www.sciencedirect.com/science/article/pii/S095965261833960X

I hope this answers your question
