Extent: E+W+S+N.I.

HALEO∕CG=ARITHMETIC MEAN∑i=1nHALi,k×CFEOE,i
whereby:
HALEO/EG:historical activity level for ethylene oxide/ethylene glycols production expressed in tonnes of ethylene oxide equivalents
HALi,k:historical activity level for the production of the ethylene oxide or glycol i in year k of the baseline period expressed in tonnes
CFEOE,i conversion factor for the ethylene oxide or glycol i relative to ethylene oxide
Following conversion factors shall be applied:
Ethylene oxide: 1,000
Monoethylene glycol: 0,710
Diethylene glycol: 0,830
Triethylene glycol: 0,880
