Emissions quantification methodologies

Reporting operations must use specified or approved methodologies for quantifying their GHG emissions. 

All reporting operations must use the core 2011 Western Climate Initiative (WCI) quantification methods in combination with the 2012 and 2013 amendments, as applicable per activity and reporting period. See table.

Amended quantification methods for 2012

  • In February 2012, the Western Climate Initiative released the Final Essential Requirements for Mandatory Reporting – Amended for Canadian Harmonization - Second Update (PDF, 1.2MB) as an update to the December 2011, publication of “Final Essential Requirements for Mandatory Reporting – Amended for Canadian Harmonization.”
  • Starting with the 2012 reporting period, all reporting operations must use the second update of the amended WCI quantification methods – with updates to: WCI.020 (General Stationary Combustion), WCI.350 (Natural Gas Transmission and Distribution) and WCI.360 (Petroleum and Natural Gas Systems). Where a method was not updated, the Amended Quantification Methods for 2011 (see below) must be used for the 2012 reporting period.
  • For both 2011 and 2012 reporting, several errata changes have been made in the WCI second update document that clarify specific parts of the WCI.040 Electricity Generation, WCI.090 Cement Production, WCI.160 Lead Production, WCI.240 Zinc Production and WCI.210 Pulp and Paper Production quantification methods.
  • For both the 2011 and 2012 reporting periods alternative parameter measurement and replacement methodologies covered in Section 13 of the Reporting Regulation (PDF, 688KB) would apply as appropriate. Separate alternative parameter applications are required for the 2012 reporting period to any previously submitted and are only applicable to where a specific method is new or modified.
 

Amended quantification methods for 2011

  • In December 2010, the Western Climate Initiative published the “Final Essential Requirements for Mandatory Reporting – Amended for Canadian Harmonization”. Starting with the 2011 reporting period (to be reported by March 31, 2012), all reporting operations are required to use the amended WCI quantification methods for all activities as listed in Tables 1 and 2 in the Reporting Regulation (PDF, 688KB).
  • For the 2010 reporting period (to be reported by March 31, 2011), reporting operations must continue to use the original July, 2009 WCI Essential Requirements of Mandatory Reporting or B.C. quantification methods as published in the 2010 Methodology Manual.
  • For both the 2010 and 2011 reporting periods, alternative parameter measurement and replacement (alternative) methodologies covered in Section 13 of the regulation would apply, as appropriate. Separate alternative parameter applications will be required for the 2011 reporting period to any previously submitted.
