output flox impacts

Question

Hello

I'm training on openlca with a tutorial and I'm having a problem with the output flows impacts. I have created a flow of nitrate in the output water and its impact does not appear in the results. Are there any special precautions I need to take to ensure that these impacts are taken into account?

Thanks

Hi,

yes make sure you choose the right flow and the right impact assessment method. If you open the respective elementary flow for nitrate, you can see a tab with 'Characterisation factors', there you will find the methods and categories that assess this flow. See: https://greendelta.github.io/openLCA2-manual/flows/flow_tabs_contents.html

Also, if it is not assessed, it will show in the LCIA checks: https://greendelta.github.io/openLCA2-manual/res_analysis/res_lcia_checks.html
Hope this helps
