On July 11, 2009, Environment Canada issued a notice requiring any person who operates a facility that emits 50 kilotonnes or more of carbon dioxide equivalent (CO2e), in the 2009 calendar year to submit information about those emissions to the federal government no later than June 1, 2010. Environment Canada has required such reporting since the 2004 calendar year, but previously had only required reporting by facilities that emitted 100 kilotonnes or more of CO2e in a calendar year.
