Emission Trends

Success in reducing pollutants depends on the nature of the sources producing the emissions. For example, pollution caused by transportation has been difficult to address due to exponential growth in the number of cars on the roads. On the other hand, reductions SO2 emissions have been easier to achieve by targetting a relatively small group of large emitters such as electricity generating facilities.

A key factor to reducing emissions levels is the amount of consumption by a country. Canada has had a pattern of high energy consumption, making the country to be the second highest per capita emitter of greenhouse gases in the world.
