# Commission Regulation (EU) No 601/2012 of 21 June 2012 on the monitoring and reporting of greenhouse gas emissions pursuant to Directive 2003/87/EC of the European Parliament and of the Council (Text with EEA relevance) (repealed), Division B: Determination of PFC emissions

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

PFC emissions shall be calculated from the emissions measurable in a duct or stack (‘point source emissions’) as well as fugitive emissions using the collection efficiency of the duct:
PFC emissions (total) = PFC emissions (duct)/collection efficiency
The collection efficiency shall be measured when the installation-specific emission factors are determined. For its determination the most recent version of the guidance mentioned under Tier 3 of section 4.4.2.4 of the 2006 IPCC Guidelines shall be used.
The operator shall calculate emissions of CF4 and C2F6 emitted through a duct or stack using one of the following methods:
(a) Method A where the anode effect minutes per cell-day are recorded;
(b) Method B where the anode effect overvoltage is recorded.
