Environment and Climate Change Canada (ECCC) publishes the National Inventory Report (NIR) annually — Canada's official submission to the UNFCCC. The NIR is the authoritative source for historical GHG emissions by province, sector, and gas type, covering CO2, CH4, N2O, HFCs, PFCs, SF6, and NF3 under the Kyoto/Paris framework.
The ECCC Greenhouse Gas Reporting Program (GHGRP) requires facilities emitting ≥ 10,000 t CO2e/year to report annually. Facility-level data is published with a ~2-year lag, enabling large-emitter benchmarking, carbon credit valuation, and ESG-grade supply chain analysis.
ECCC also publishes the annual GHG Progress Report tracking progress against Canada's Nationally Determined Contribution (NDC) under the Paris Agreement: -40 to -45% below 2005 levels by 2030.
