Reporting Committee Archive PDF Print

The Reporting Committee worked to develop a greenhouse gas emissions reporting system that will support the WCI cap-and-trade program by ensuring that WCI jurisdictions receive necessary and accurate emissions data in a timely manner. 

Elements of the reporting system include jurisdictional reporting rules, reporting tools, and a regional emissions database. Jurisdictional reporting rules include, at a minimum, a common set of functionally equivalent requirements sufficient to ensure that "a metric ton is a metric ton" across the WCI Partner jurisdictions.

The final version of the first group of the Essential Requirements for Mandatory Reporting were released on July 15, 2009.  


This release included general provisions governing all reporters; requirements for third-party verification; and greenhouse gas monitoring, reporting, and recordkeeping for the following source categories:

  • General Stationary Combustion
  • Refinery Fuel Gas Combustion
  • Electricity Generation
  • Electricity Imports
  • Primary Aluminum Manufacturing
  • Cement Manufacturing
  • Coal Storage
  • Hydrogen Production
  • Iron and Steel Manufacturing
  • Lime Manufacturing
  • Petroleum Refining
  • Pulp and Paper Manufacturing
  • Soda Ash Production
  • Petrochemical Production
  • Adipic Acid Manufacturing


To minimize the reporting burden in the U.S., the Reporting Committee harmonized WCI Partners’ reporting requirements with the U.S. EPA Mandatory Reporting Rule for GHG emissions.  The Committee also developed a Canadian version of the reporting requirements

The WCI Partner jurisdictions are continuing to develop reporting protocols for some emission sources that do not yet have adequate quantification methods.
