Air Emissions From Natural Gas October 1997Table 1
Canadian Natural Gas - 1997 Supply and Reserves Disclaimer: Although the Canadian Gas Association has mask every effort to ensure the accuracy of data appearing in this publication the Association cannot assume responsibility for inaccuracies which may occur.
Introduction This report outlines the atmospheric emissions from the natural gas industry in Canada, and emissions from the consumption of natural gas. It includes reference to both greenhouse gases (carbon dioxide, methane and nitrous oxide) and oxides of nitrogen which contribute to ground-level air quality concerns such as smog formation. It also compares Canadian emissions with those from other countries and provides information on the global situation with respect to emissions from anthropogenic (human-caused) sources. Projections of future use of natural gas and resulting emissions are also included, in the context of what emissions might be if natural gas is not used to meet continually increasing energy demands of Canadians. There are environmental benefits to switching from higher hydrocarbon fossil fuels to natural gas. These have been well documented in other literature and are not discussed in detail in this report. This report also updates the 1990 baseline inventory which the Canadian Gas Association (CGA) carried out in 1994. The update serves to make the point that baseline inventories of emissions remain subject to continuing modification as new and more complete in formation becomes available. Natural Gas in Canada Demand for natural gas continues to grow. In Canada it currently provides some 31% of primary energy’. Forecasts to 2010 indicate that growth in volumes of natural gas consumed in Canada is expected to continue at about 2% per 2010 In addition, over 50% of Canadian natural gas production is currently exported to the United States, where Canadian gas meets about 13% of US demand.

· Annual growth of 2% in natural gas demand to 2010 Impacts
The natural gas industry in Canada, being new in comparison to some other countries, has taken advantage of the latest in low emission technology and techniques. In addition, the industry has strongly supported the Voluntary Challenge and Registry (VCR) since its inception in 1994. Efforts were also underway well before the VCR was established to improve efficiencies and reduce emissions. Climate Change and the VCR
The contribution by Canadians to global anthropogenic greenhouse gases (GHG) is both big and small, depending on how one views it. We are among the highest per capita producers of GHG in the world, mainly because we are also among the highest per capita producers of energy-intensive materials that meet worldwide demand. We also have vast distances to transport people and materials, and a cold climate in comparison to most other countries. These features are among those which lead us to consume more energy per capita than smaller and warmer countries. But our comparatively small population also means that, in total, we produce only about 2.1% of all global anthropogenic emissions. Given the economic benefits from our energy use it should be emphasized that for Canada it is not energy waste but high energy intensity that leads to our high energy rates per capita.
