In November 2008, the Minister of Sustainable Development, Environment and Parks published a report entitled "The Québec Inventory of Greenhouse Gas Emissions". The report shows that greenhouse gas emissions rose 1.6% in Québec between 1990 and 2006, whereas the Canadian average totals 21.8%. Québec emits less than 12% of the country's emissions, even though it represents almost 25% of its population. The report also indicates that Québec is one of the provinces with the lowest rate of emissions per capita, a rate that has decreased by 7% since 1990. The document also shows, however, that transportation is the largest emitter of greenhouse gases, representing 40% of the total emissions.
The Québec Inventory is comprised of data that has been gathered from businesses and institutions on an annual basis since 1990, as well as statistics obtained from Statistics Canada, the Québec Institute of Statistics, the Department of Natural Resources and Wildlife, the Department of Agriculture, Fisheries and Food, and the Société de l'assurance automobile du Québec, in accordance with the methods of data compilation adopted by the United Nations Framework Convention on Climate Change.
