Maps of reporting facilities – criteria air contaminants

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 direct releases of Criteria Air Contaminants 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, NPRI）是加拿大面向公众的污染物排放（排放至大气、水体与陆地）、废物处置及循环利用转移相关数据的公开名录。

以下文件包含一张加拿大地图，标注了所有向NPRI报告标准空气污染物直接排放的设施的位置。本数据采用最新报告年度的统计口径，按上述污染物的报告总排放量进行整理。

该地图提供ESRI REST（适配ARC GIS）与WMS（开源）两种格式。如需查询单个报告设施的详细信息，可获取CSV格式的数据集。
