The Reporting Committee is developing 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 will need to include jurisdictional reporting rules, reporting tools, and a regional emissions database. Jurisdictional reporting rules will need to 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.  

• Essential Requirements for Reporting (complete document)
• Response to Stakeholder Comments on the Final Draft ERMR and ERMR Markup

This release includes 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 WCI Partners’ reporting requirements are harmonized with the U.S. EPA Mandatory Reporting Rule for GHG emissions.  The WCI Partner jurisdictions are currently developing 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. Chief among these are oil and gas production, natural gas processing, and natural gas transmission and distribution, which are significant sources of GHG emissions in some WCI Partner jurisdictions.  See WCI Comments on the Proposed Mandatory Reporting of GHG Emissions from Proposed Reporting for Oil and Gas Operations (Subpart W).
