Organization carbon footprint - scope 3

Question

Hello

in the organization's carbon footprint calculation, I put electricity consumption in scope 2.

But I have a problem with energy related emissions to be shown in scope 3 category 3.

If I want to avoid double counting I should have the emission factor of electricity divided by phase, specifically:

- electricity use phase to be entered in scope 2

- upstream phase of electricity production at the facility where it is produced to be entered in scope 3

- T&D and grid losses to be entered in scope 3.

In Ecoinvent the process market electricity medium voltage IT contains in aggregate form all the contributions so I cannot divide the contributions into the different scopes.

So what can I do?

1. calculate the emissions of the electricity used and enter them only in scope 2

or

2. where to find the emission factors divided by stage of electricity production and distribution.

Thanks to those who can help me.

Hello Tarlon,

To answer the question, i will assume you are using ecoinvent.

It sounds like you are using the LCI database, which only gives you the processes in elementary flows.

If you access the UPR database, you will see the market process divided into several streams. If you calculate the UPR as a product system, you will be able to see the CO2 from each stream. It might be easier to export the results, and treat the data in excel.

OpenLCA was not set up for this type of calculation, and there are allocation choices made in each database that do not necessarily align with the GHG protocol or ISO 14064. Use with caution.

I hope this helps, good luck.

Thank you very much.
I can not see Files section.
This is the problem.
Thanks again for your effort.
