Hello,
I am currently gathering GWP values for different materials in order to calculate the carbon footprint of products (systematic approach).
I am performing assessments with both IPCC 2021 versions to get all the impact categories required from the standard.
But I am not sure about how to retrieve standard deviations for these GWP values.
I figured, since inputs and outputs come with log normal uncertainty distributions, to perform Monte Carlo simulations and get the STD Dev from there.
I was wondering if this is the correct way to evaluate uncertainty of GWP values (since they are also required according to ISO 14067).
Or if this is not the case, how should I go about evaluating them?
Thank you!
