National Pollutant Release Inventory

The National Pollutant Release Inventory (NPRI) is Canada's legislated, publicly accessible inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. It is a key resource for: identifying pollution prevention priorities; supporting the assessment and risk management of chemicals, and air quality modelling; helping develop targeted regulations for reducing releases of toxic substances and air pollutants; encouraging actions to reduce the release of pollutants into the environment; and improving public understanding. The NPRI comprises: Information reported by facilities and published by Environment and Climate Change Canada under the authority of Sections 46 – 50 of the Canadian Environmental Protection Act, 1999 (CEPA 1999); and Comprehensive emission summaries and trends for key air pollutants, based on facility-reported data and emission estimates for other sources such as motor vehicles, residential heating, forest fires and agriculture. For the latest reporting year, 7,708 facilities reported to the NPRI on more than 300 listed substances. Comprehensive air pollutant emission summaries and trends were compiled by Environment and Climate Change Canada for criteria air contaminants (the main pollutants contributing to smog, acid rain and/or poor air quality), selected heavy metals and persistent organic pollutants.

国家污染物排放清单（NPRI）是加拿大依法设立、公众可查询的污染物排放（至空气、水体和陆地）、处置及回收转移的目录。该目录是以下关键资源的核心：识别污染防治优先事项；支持化学品及空气质量建模的风险评估与管理；协助制定旨在减少有毒物质和空气污染物排放的针对性法规；鼓励采取减少污染物排放至环境中的措施；以及提升公众对该问题的理解。NPRI包含：根据加拿大环境保护法1999年（CEPA 1999）第46至50条的规定，由设施报告并由加拿大环境与气候变化部发布的报告信息；以及基于设施报告数据和针对其他来源（如机动车、住宅供暖、森林火灾和农业）的排放估算的，对主要空气污染物（主要污染物，包括形成烟雾、酸雨和/或恶劣空气质量的主要污染物）以及选定重金属和持久性有机污染物的全面排放总结和趋势。在最新报告年度，共有7,708个设施向NPRI报告了超过300种列出的物质。加拿大环境与气候变化部编制了针对标准空气污染物的全面空气污染物排放总结和趋势，包括主要污染物、选定重金属和持久性有机污染物。)
