National Pollutant Release Inventory: Canadian Facility Emissions and Transfers by Year

Canada's National Pollutant Release Inventory (NPRI) is a public registry of pollutant releases, disposals, and transfers reported by industrial and commercial facilities. The dataset is published by Environment and Climate Change Canada and contains annual facility-level data presented in filterable tables. The data was last updated on 2026-04-30.

Use Cases

• Analyze trends in industrial air, water, and land pollution releases based on annual facility reporting.
• Assess the scale and destination of waste transfers for recycling based on reported transfer data.
• Benchmark facility-level environmental performance against industry peers using the reported substance data.
• Support regulatory compliance monitoring and policy evaluation based on the national inventory scope.

Strengths

• Data is reported directly by facilities under a national regulatory program, suggesting a structured collection method.
• The dataset is published by the authoritative government body, Environment and Climate Change Canada.
• Data is available in multiple accessible formats including CSV, XLS, and XLSX.
• The dataset is licensed under the open OGL-CA-2.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Freshness should be verified as the last update timestamp is 2026-04-30.
