Hi all, When using both A1 and A2 data, how to deal with mass balance?

Hi Elisa,

For mass balance purposes you will set the mass/unit for one datapoint to 0, and the other to 1. It is preferable to set the mass/unit to 1 for the +A2 data.

If you are scaling the mass of one datapoint/EPD to make the final impacts of the two different data more similar please set the mass/unit to 1 for the datapoint whose mass has not been modified.
