National Greenhouse Gas Emissions

Canada's total greenhouse gas (GHG) emissions in 2013 were 726 megatonnes (Mt) of carbon dioxide equivalent (CO2 eq),Footnote [1] or 18% (113 Mt) above the 1990 emissions of 613 Mt. Steady increases in annual emissions characterized the first 15 years of this period, followed by fluctuating emission levels between 2005 and 2008, a steep decline in 2009, and a slight increase thereafter.

Canada's emissions growth between 1990 and 2013 was driven primarily by increased emissions from the fossil fuel industries and transport. Emission reductions from 2005 to 2013 were driven primarily by reduced emissions from the public electricity and heat production category.

How this indicator was calculated

Note: The national indicator tracks seven GHGs: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulphur hexafluoride (SF6), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs) and nitrogen trifluoride (NF3) released by human activity (reported in Mt of CO2 eq). Canada signed the Copenhagen Accord in December 2009, thereby committing to reducing its GHG emissions to 17% below 2005 levels by 2020. Emission levels for some previous years have been revised in light of improvements to estimation methods and availability of new data.

GHGs trap heat in the Earth's atmosphere, just as the glass of a greenhouse keeps warm air inside. Human activity increases the amount of GHGs in the atmosphere, contributing to a warming of the Earth's surface. This is called the enhanced greenhouse effect.

Over the past 200 years in particular, humans have released GHGs into the atmosphere primarily from burning fossil fuels. As a result, more heat is being trapped and the temperature of the planet is increasing. Sea levels are rising as Arctic ice melts, and there are changes to the climate, such as more severe storms and heat waves. All of this impacts the environment, the economy and human health.

Footnotes

Footnote 1

Greenhouse gas emissions from the National Inventory Report (NIR) were estimated with the help of the new United Nations Framework Convention on Climate Change (UNFCCC) reporting guidelines. These new guidelines include the adoption of revised methodologies in accordance with Intergovernmental Panel on Climate Change (IPCC) guidelines, and the use of revised global warming potentials (GWPs).
