Hello,

I would like to calculate the carbon intensity associated with LNG using the 4.03a version of GHGenius. Natural gas is sourced from the grid and liquefied within the LNG facility with few by-products, as it comes very “clean” already. We have the information on natural gas composition, and we would like to identify all inputs in the tool to support the facility to measure all the necessary data for an accurate CI.
So far, I could identify the following for LNG production:
• Input on facility energy and leakages at ‘service stations tab” columns C19 TO C27.
• Results taken from: Upstream Results HHV, cell Q8 to Q19.
What other inputs can be used in the tool to calculate this CI?

thank you in advance,
regards,
Clarice

This pathway does not have a lot of inputs in version 4.03a. The ones that you have identified are all that there are for the production.

On the Input sheet there are transportation parameters in column AN rows 92 to 102.

Thank you again for this response.
I have one follow-up question regarding the LNG carbon intensity:

Could you help me understand if the carbon intensity results include flaring of gases that are not reused/recovered or are assumed only fugitive emissions of those gases? Would it be possible to enter the specific amount of gas flared in the process for more accurate results?

Thank you,
Regards,
Clarice
