Viktor,
This does not answer the question. I understand how you estimate direct emissions. Here I would like to know how you calculate life cycle emissions including direct and indirect ghg emissions. For indirect emissions you cannot rely on ENSTO and EU ETS datanbase. This number as to come from elsewhere. So, how do you calculate indirect natural gas GHG emissions for Europe ?
Best regards.

You got it. Gas is not mentioned! So we do not know the source of information used by electricitymap for upstream gas activities. Do you have any clue ?

Hi @Stefhis974, sorry for the delay in answering, I was on holidays for an extended period of time.
I have corrected the omission of some upstream emission factors in our wiki: https://github.com/electricitymaps/electricitymaps-contrib/wiki/EU-emission-factors
Indeed, the upstream emission factors are computed as the difference between the default lifecycle and direct emission factors

Hi!
We use the EU-ETS data for the total emission of a plant and map that with the total generation from ENTSO-E and from those two values we derive the emission factor for that plant.
After that is done we average all the emissions from all plants in a zone that has the same production fuel (in this case gas) and use that as the emission factor.
You can find more details on how this works and the code used here: https://github.com/electricitymaps/electricitymaps-contrib/wiki/EU-emission-factors

Oh, not my area of expertise but I think we used the difference between IPCC direct emissions and IPCC lifecycle emissions as the upstream attribution. But I think this could be better explained by @mathilde-daugy or @pierresegonne if you need more details.

It may be what you propose or may be something else. Can you connect me with Pierre or Mathilde to finalise this issue ?

I have pinged them in the github issue, and they'll likely respond when they have the time.

Dear Viktor,
I trust you are doing well. I whish you a happy 2024 new year. About upstream natural gas emissions factors still no news from your colleagues. This is too bad, since it’s important giving the role some EU countries wants natural gas to play. I hope one day I will have the answer.
Best regards.

Closing this as @pierresegonne has updated documentation :)
