Canadian industrial emitters of greenhouse gases (GHGs) have until June 1, 2010 to report their 2009 GHG emissions. Data collected will be used to create a domestic GHG inventory, harmonizing emissions reporting across Canadian jurisdictions. The reporting deadline, which was established by Environment Canada, applies to facilities that emit over 50,000 tonnes of CO2 equivalent per year, replacing the 100,000 tonne threshold that has been in effect since the introduction of the Greenhouse Gas Emissions Reporting Program in 2004.

The reporting deadline is an element of the federal government's efforts to develop regulations aimed at combating GHGs. Environment Minister Jim Prentice has indicated that regulations will be unveiled prior to December's climate change talks in Copenhagen. As reported in our June 2009 Energy Law Update, the government has published guidelines for a domestic offset program that will form part of Canada's proposed cap-and-trade system, but has yet to develop sector-specific regulations for regulated entities.

Reporting facilities must keep copies of the required information, along with calculations, measurements and other underlying data, in Canada for a three-year period from the required date of submission. Reporting requirements are detailed in the Canada Gazette Notice for 2009 Emissions.
