The units covered by the CO2 Emission Trading Scheme, i.e. the Refinery, the Combined Heat and Power Plant and the Petrochemical Cracking, were committed to pay PLN 1,513,203.81 in fees for the allowances granted for the second trading period of 2008–2012. Consequently, the CO2 emission fee was deducted from the environmental fee.
Reduced fees for water uptake and sewage discharge in 2008 were due to a 2.9% drop in sewage discharge, a new reference method for COD identification and a 3.1% drop in surface water uptake from the Vistula compared to 2007.
