Dear One Click LCA Support Team,

I hope this message finds you well.

I am writing to kindly request clarification regarding the efficiency multiplier value of 1.18, which appears under the Resource Localised Energy Profile for Electricity, Iran, 2022 (IEA2022) in the localisation section.

I would be most grateful if you could assist me with the following questions:

  1. Calculation Method:
    Could you please explain how this efficiency multiplier (1.18) is calculated?
  • What formula or methodology is used?
  • Are there specific assumptions, benchmarks, or reference factors involved in its derivation?
  1. Source or Data Origin:
    May I ask which dataset or publication this multiplier is based on?
  • Is it derived from IEA statistics or another source?
  • If available, I would deeply appreciate a reference or citation to the original document.
  1. Citation Guidance:
    As I intend to reference this data in a scholarly or technical publication, could you kindly advise on the appropriate way to cite this multiplier and its source?

Thank you very much for your kind support and for the valuable work you provide through the One Click LCA platform. I sincerely appreciate your assistance and look forward to your guidance.

Dear One Click LCA Support Team,
Dear Steve,

I hope you are doing well.

Following up on my previous inquiry regarding the efficiency multiplier of 1.18 shown for Electricity, Iran, 2022 (IEA2022), I would be sincerely grateful if I could receive further clarification on the following points:

  1. Efficiency Multiplier (1.18):
  • Could you kindly explain how this value is calculated?
  • What methodology, assumptions, or reference parameters are used in its derivation?
  • From which dataset or publication is this value sourced? I would greatly appreciate a citation or reference for academic use.
  1. Emission Factor (0.77 kg CO₂e / kWh):
  • As per the IEA2022 profile, does this emission factor already include transmission and distribution losses?
  • If I intend to conduct a full life cycle analysis for stage B6 (operational energy use), should I separately account for national transmission and distribution (T&D) loss rates reported by IEA by adding them to this value, or are they inherently embedded?

Given the complexity and importance of the B6 phase in my analysis, I want to ensure that all energy losses are properly accounted for to reflect real-world emissions.

I would be extremely grateful if @Steven could assist with this matter, as I understand he has deep expertise in this area.
