Introduction
Currently 90% of the world’s primary energy requirement is supplied by fossil fuels, causing rising emissions of greenhouse gases (GHGs) and related concerns over global warming and climate change. CO2 is by far the most important of the GHGs, being responsible for about 64% of the enhanced greenhouse effect. As a result of anthropogenic CO2 emissions, atmospheric concentrations have risen by 30% from pre-industrial levels of 280 ppm to 360 ppm today, primarily as a consequence of fossil fuel use. However, at the current state of development, and the levels of risks and cost of

It is estimated that in the Kyoto compliance period (2008-2012), this gap will increase to the tune of 240 Mt of CO2 equivalent (Pearson, 2003) Figure 3 and Figure 4 give a break-up of Canada’s GHG emission profile for industrial and upstream oil and gas sector (CEO, 1999) Most of these emission sources are located in the Western Canadian Sedimentary Basin (WCSB) (CEO, 1999).
