GHG Reporting Notice Extended to 2026

Summary#

This notice from Environment and Climate Change Canada amends the greenhouse gas reporting requirements under the Canadian Environmental Protection Act, 1999. It extends the existing reporting notice so that required facility reporting now covers the calendar years 2024, 2025 and 2026, with specific deadlines for submitting data.

What it does#

• Changes the title of the reporting notice to Notice with respect to reporting of greenhouse gases (GHGs) for 2024, 2025 and 2026 to reflect the added year.
• Requires any person who operates a facility covered by the notice and who has (or could reasonably access) the listed information to provide that information for the years 2024, 2025 and 2026.
• Sets reporting deadlines:
  • 2024 data due by June 2, 2025
  • 2025 data due by June 1, 2026
  • 2026 data due by June 1, 2027
• Keeps the main reporting threshold at 10 000 tonnes of carbon dioxide equivalent (CO2‑eq.) per year. Facilities that meet or exceed that threshold in any of the three years must report.
• Clarifies that facilities engaged in CO2 capture, CO2 transport, CO2 injection, CO2 utilization or CO2 storage during those years are included.
• Requires operators who previously reported but later determine their facility no longer meets the criteria to notify the minister by the same reporting deadlines above.
• Provides the formula and steps for calculating “Total Emissions” using emissions of CO2, methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), per‑ and polyfluorinated compounds (PFCs) and sulfur hexafluoride (SF6) multiplied by their global warming potentials.

Who's affected#

• Operators of facilities that emit at least 10 000 tonnes of CO2‑equivalent in 2024, 2025 or 2026.
• Facilities involved in CO2 capture, transport, injection, utilization or storage during those years (these are included even if the notice does not explicitly tie them to the numerical threshold).
• Anyone who holds the technical or operational information listed in the notice for those facilities (because they must provide it to the minister).
• If it’s unclear whether a specific site meets the criteria, the operator is responsible for determining that and for notifying the minister if the site no longer qualifies by the listed deadlines.

Why it matters#

• The change extends mandatory reporting to include 2026, so the government will collect three years of consistent facility-level emissions data instead of two.
• That data feeds Canada’s emissions inventory and helps shape research, environmental reporting, and policy tools such as guidelines or codes of practice.
• For affected operators, it means another year of paperwork and data preparation, and a firm set of deadlines to meet.
• For the public, it means more government‑collected information on large emitters and on facilities handling CO2, which can affect transparency around industrial emissions and climate action.
