The notes in this query should be updated, they now still refer to the non-energetic emissions as well.

Few comments:

  • The notes refer to primary_co2_of_non_energetic_and_delayed_emissions, which is now split into separate queries for non energetic and delayed emissions. Therefore, the notes should refer to primary_co2_of_non_energetic.
  • 3rd sentence: change beginning of the sentence to 'this node's primary CO2 emissions will at...'

# the primary CO2 emissions will at the moment always be 0 since its free_co2_factor is 1 (no C atoms will be released in non-energetic use of methanol).
# For now, there is no situation where we have nodes with group co2_emissions_refinery_products with non-energetic use where primary CO2 emissions should be taken into account.

Few comments regarding query notes:

  • the part referring to delayed emissions should be removed
  • change the last sentence to refer to the specific group and sector, such as 'non-energetic final demand of group co2_emissions_refinery_products in the industry sector is not (yet) included in this query, which currently only consists of non-energetic methanol final demand. Since its free_co2_factor is 1.0, the method of querying this node currenlty doesn't affect the results'.
  • Make sure to break a sentence to the next line when it gets too long, currently the case for the last sentence

I'm not sure I understand this added sentence correctly, can you explain this?
