2Where it sits in the industry spread

0.0% of 8 · smaller than the median

EEA · 단위 t*kmBottom 25% band

Compared against 8 factors in the same unit (t*km). Product families may be mixed, so treat it as indicative only. Measuring concrete and steel sheet with the same ruler says little.

Notes

  1. 1)The value is as published by EEA; we do not alter it. EEA 공개 자료
  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
