PollutionData — Canadian GHG & Pollutant Releases (Sample)
Sample of 5,000 Canadian facility-level environmental records across 3,005 facilities. Mix of pollutant releases (NPRI) and greenhouse gas emissions (GHGRP). Last 2 years of data from the full PollutionData API.
Want the full dataset? 1.08M+ records, every NPRI/GHGRP-reporting facility in Canada since 1993, queryable by facility / pollutant / industry / region. Get an API key →
What's in here
| Field | Type | Description |

string | Pollutant / GHG type |
facility_id |
string | Stable facility identifier (NPRI/GHGRP) |
total_co2e |
float | Total CO2-equivalent emissions in tonnes (where applicable) |
data |
object | Full raw record from the source (JSON) — quantities, NAICS, NPRI codes |
Composition (sample)
| entity_type | rows |
|---|---|
| release (NPRI pollutants) | 4,000 |
| emission (GHGRP GHGs) | 1,000 |
3,005 unique facilities represented.
Use cases
- ESG due diligence — counterparty and supply-chain emissions screening
- Carbon accounting — Scope 3 input data for upstream supplier emissions
- Climate research — emissions trends, polluter benchmarking, regional analysis
- RAG / agents — ground LLM responses in actual Canadian industrial emissions data
- Compliance & benchmarking — compare facility performance against industry peers
- Journalism / NGO reporting — identify largest polluters in a region or sector
- Schema exploration before committing to API integration
Limitations of this sample
- Snapshot only — frozen 2026-05-25. New reports added annually as facilities file.
- 5K rows — full dataset is 1.08M+. Sample is enough to test schema, prompts, prototypes; not enough for production analytics.
- No querying — can't filter by pollutant, NAICS, facility, or year. Use the API for that.
- Year-precision dates — NPRI/GHGRP are annual reports, not transactional records.
