Environment Canada published an October 1, 2011, notice in the Canada Gazette alerting large industrial facilities—those producing 50,000 metric tons or more of carbon dioxide-equivalent annually—that they are required to report their greenhouse gas (GHG ) emissions by June 1, 2012. The reporting requirement applies to emissions of carbon dioxide, methane, nitrous oxide, and sulfur hexafluoride, and to multiple types of hydrofluorocarbons and perfluorocarbons.

For carbon dioxide, methane and nitrous oxide, facilities must report the total quantity of direct emissions by source category—stationary fuel combustion, industrial processes, venting, flaring, on-site transportation activity, and waste and wastewater disposal and leaks. Facilities must also report total direct emissions of “sulfur hexafluoride, hydrofluorocarbons by individual species, and perfluorocarbons by individual species, from industrial processes and industrial product use.”

Reporting must include an outline of the method used to estimate emissions and must be accompanied by a statement of certification, signed by “an authorized signing officer.” Failure to comply with the reporting requirement is subject to a penalty of up to $1 million and/or jail terms up to three years.
