Gas for heating and with certificates

Hi, I am trying to find a suitable approach for adding a consumption of gas for internal heating in factory in my LCA. I found a datapoint, but this is not neutral and creates both heat and elecrticity. As we have bought certificates, I would like to be able to offset to zero anyway. How do I do this?

Hi,

Please note that carbon offsets are not allowed as they are not part of the system under study as seen in the snapshot below from standard EN15804+A2.

This means that a generic datapoint should be used for the consumption of gas for internal heating.
