Canada was active in the negotiations that led to the Kyoto Protocol in 1997. The Liberal government that signed the accord in 1997 ratified it in parliament in 2002. Canada's Kyoto target was a 6% total reduction in greenhouse gas (GHG) emissions by 2012, compared to 1990 levels of 461 megatonnes (Mt) (Government of Canada (GC) 1994). Despite signing the accord, greenhouse gas emissions increased approximately 24.1% between 1990 and 2008. In 2011, Conservative Prime Minister Stephen Harper withdrew Canada from the Kyoto Protocol.
