# Commission Implementing Regulation (EU) 2018/2066 of 19 December 2018 on the monitoring and reporting of greenhouse gas emissions pursuant to Directive 2003/87/EC of the European Parliament and of the Council and amending Commission Regulation (EU) No 601/2012 (Text with EEA relevance), Division 3: DETERMINATION OF GHGS USING MEASUREMENT-BASED METHODOLOGIES

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

Equation 1: Calculation of annual emissions in accordance with Article 43(1):
GHG Em total t = ∑ i = 1 HoursOp GHG conc hourly,i × V hourly,i × 10 − 6 t ∕ g
Equation 2: Determination of average hourly emissions:
GHG Em average kg ∕ h = GHG Em total HoursOp × 10 3 kg ∕ t
Equation 2a: Determination of average hourly GHG concentration for the purpose of reporting in accordance with point 9(b) of Annex X, section 1:
GHG conc average g ∕ Nm 3 = GHG Em total ∑ i = 1 HoursOp V hourly,i × 10 6 g ∕ t
Equation 2b: Determination of average hourly flue gas flow for the purpose of reporting in accordance with point 9(b) of Annex X, section 1:
Flow average Nm 3 ∕ h = ∑ i = 1 HoursOp V hourly,i HoursOp
Equation 2c: Calculation of annual emissions for the purpose of the annual emission report in accordance with point 9(b) of Annex X, section 1:
GHG Em total t = GHG conc average × Flow average × HoursOp × 10 − 6 t ∕ g
The following abbreviations are used in Equations 1 to 2c:
The index i refers to the individual operating hour. Where an operator uses shorter reference periods in accordance with Article 44(1), that reference period shall be used instead of hours for these calculations.
GHG Emtotal total annual GHG emissions in tonnes
GHG conchourly, i hourly concentrations of GHG emissions in g/Nm3 in the flue gas flow measured during operation for hour i;
Vhourly, i flue gas volume in Nm3 for hour i (i.e. integrated flow over the hour or shorter reference period);
GHG Emaverage annual average hourly emissions in kg/h from the source;
HoursOp total number of hours for which the measurement-based methodology is applied, including the hours for which data has been substituted in accordance with Article 45(2) to (4);
GHG concaverage annual average hourly concentrations of GHG emissions in g/Nm3;
Flowaverage annual average flue gas flow in Nm3/h.
