Notes

  1. 1)The value is as published by UK DEFRA; we do not alter it. UK Government GHG Conversion Factors
  2. 2)Factor values in the table are unified to kgCO₂e for comparison. The original unit is in "Factor specification".
  3. 3)Even with several editions the value often stays the same. "Checked and unchanged" is an answer too.
  4. 4)One of 13,844 factors from public sources. ecoinvent, EXIOBASE and IEA factors bar redistribution, so they aren't here. See why
