Canada's National Inventory Report for 2007 emissions was filed with the UN on April 17, 2009 in compliance with its reporting obligations under the Kyoto Protocol. The report shows that there has been a 4% increase in GHG emissions in Canada since 2006 and more than a 26% increase since 1990. This increase makes Canada the G8 nation with the most significant rise in GHG emissions. Under the Kyoto Protocol, Canada pledged to reduce emissions to 6% below 1990 levels. This latest report confirms that as of 2007 Canada was 33.8% above its international commitment. The report indicates that transportation and energy production are primarily responsible for the rise in emissions as these sources account for about 143 million tons of the 155 million tons increase since 1990.
