# 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](https://pollutiondata.ca).

> **Want the full dataset?** 1.08M+ records, every NPRI/GHGRP-reporting facility
> in Canada since 1993, queryable by facility / pollutant / industry / region.

## What's in here

| Field | Type | Description |
|---|---|---|
| `source_id` | string | Originating system (`npri` or `ghgrp`) |
| `entity_type` | string | `release` (NPRI pollutant release) or `emission` (GHGRP greenhouse gas report) |
| `record_id` | string | Stable per-record identifier from the source |
| `municipality` | string | Facility location |
| `event_date` | string (ISO date, year-precision) | Reporting year (YYYY-01-01) |
| `category` | 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.
