Greenhouse gas emissions
Naturally occurring greenhouse gases (GHGs) help to regulate the planet's climate by trapping solar energy that is radiated back from the Earth. Emissions from human activities over the past 200 years have amplified this natural process, and scientists predict that this trend will continue (Environment Canada 2005a). More >>
Status and trends
National status and trends
Canada's GHG emissions were an estimated 740 megatonnes (carbon dioxide equivalent) in 2003, up 24% from 596 megatonnes in 1990. The trend in estimated emissions and the target to which Canada has committed under the Kyoto Protocol—6% below the 1990 baseline by the period 2008 to 2012—are shown in Figure 3. The Kyoto Protocol specifies penalties for countries that do not meet their emissions reduction commitments (Environment Canada 2005a). More >>
What's next?Several steps to improve the GHG emissions inventory will directly improve the quality of the indicator reported through this initiative. Environment Canada's Greenhouse Gas Division is continuously planning and implementing improvements. More >>
