Methods and data qualityDescription of the air quality indicator Description of the air quality indicatorCanada has a co-ordinated air monitoring network that includes stations from across the country. A national database of concentrations of air pollutants contains information provided by the National Air Pollution Surveillance (NAPS) network, a federal–provincial–territorial co-operative network focused on urban air quality (Environment Canada 2003). This network is, in turn, complemented by information from the Canadian Air and Precipitation Monitoring Network, a federal network that measures rural and background levels of air pollutants. More >> Description of the greenhouse gas emissions indicatorThe greenhouse gas indicator, related data and trends information come directly from Canada's Greenhouse Gas Inventory Report, 1990–2003, an annual report submitted by Environment Canada as required under the United Nations Framework Convention for Climate Change (UNFCCC) and the Kyoto Protocol (Environment Canada 2005a). Emissions are estimated according to the procedures and guidelines prescribed by the Intergovernmental Panel on Climate Change (IPCC). More >> Description of the freshwater quality indicatorThe national freshwater quality indicator is based on the Water Quality Index (WQI), which is endorsed by the Canadian Council of Ministers of the Environment (Neary et al. 2001). The WQI is described further on the council's website. More >> |
