Maps of reporting facilities – total releases to air (non-CAC)

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling.

The files below contain a map of Canada showing the locations of all facilities that reported releases to air (other than Criteria Air Contaminants (CAC)) to the NPRI. The data are for the most recent reporting year, by reported total quantities of these releases.

The map is available in both ESRI REST (to use with ARC GIS) and WMS (open source) formats. For more information about the individual reporting facilities, a dataset is available in a CSV format.

Please consult the following resources to enhance your analysis:

国家污染物排放清单（National Pollutant Release Inventory，简称NPRI）是加拿大面向公众的污染物排放（排入大气、水体与陆地）、污染物处置及循环利用转移的公开清单。

下述文件包含一张加拿大地图，标注了所有向NPRI申报了除标准空气污染物（Criteria Air Contaminants，简称CAC）之外的大气污染物排放的设施点位。该数据基于最新报告年度的此类排放申报总排放量统计。

该地图提供ESRI REST（适配ArcGIS使用）与WMS（开源）两种格式。如需查询单个申报设施的详细信息，可获取CSV格式的数据集。
