GHG Reporting Notice Extended to 2026

Summary#

Environment and Climate Change Canada has amended the Notice with respect to reporting of greenhouse gases (GHGs) so the reporting requirements now cover the 2024, 2025 and 2026 calendar years under the Canadian Environmental Protection Act, 1999. Facilities that meet the notice’s criteria — notably those emitting at least 10 000 tonnes of carbon dioxide equivalent — must submit data by the deadlines: June 2, 2025 (for 2024), June 1, 2026 (for 2025) and June 1, 2027 (for 2026).

What it does#

• Changes the title of the original notice to add 2026 so it reads Notice with respect to reporting of greenhouse gases (GHGs) for 2024, 2025 and 2026.
• Extends the reporting period so the notice applies to calendar years 2024, 2025 and 2026.
• Sets the reporting threshold to 10 000 tonnes of carbon dioxide equivalent (CO2e) in any of those years.
• Makes clear that facilities involved in CO2 capture, transport, injection, utilization or storage must report if active in 2024–2026.
• Specifies deadlines for data delivery:
  • Information for 2024 due no later than June 2, 2025.
  • Information for 2025 due no later than June 1, 2026.
  • Information for 2026 due no later than June 1, 2027.
• Requires facility operators who previously reported (for example for 2023) to notify the Minister by the same deadlines if they determine their facility no longer meets the notice criteria for the upcoming year.
• Clarifies how to calculate total emissions: operators must sum emissions of CO2, CH4, N2O, HFCs, PFCs and SF6 using each gas’s global warming potential (GWP) to decide whether the 10 000 tonnes threshold is met.
• Applies to the information types listed in Schedules 4 through 18 to the notice and to facilities described in Schedule 3.

Who's affected#

• Operators of facilities in Canada that emit at least 10 000 tonnes CO2e in a calendar year. That typically includes large industrial sites such as some power plants, oil and gas facilities, heavy manufacturing, and similar operations.
• Facilities engaged in CO2 capture, transport, injection, utilization or storage during 2024–2026, even if their other emissions are below the threshold.
• Operators who filed under the earlier notice (for example for 2023) and who need to confirm or withdraw their facility from reporting for the later years.
• The notice itself lists specific facility types in Schedule 3; if it’s unclear whether a particular site is covered, the operator will need to check that schedule or contact the program.

Why it matters#

• It extends and continues mandatory national greenhouse‑gas reporting for three years, so government inventories and analyses will include consistent facility-level data for 2024–2026.
• The 10 000 tonnes threshold concentrates reporting on larger emitters, so companies that cross that line face additional reporting work and record‑keeping requirements.
• Including CO2 capture/transport/injection/utilization/storage brings carbon‑management infrastructure into the reporting picture, which matters for tracking emissions and carbon‑management activities.
• The data collected can affect future policy, emissions tracking, public transparency and any programs that rely on facility-level GHG information. If it’s unclear how the notice applies to a particular site, affected operators should consult the notice schedules or contact the Greenhouse Gas Reporting Program at Environment and Climate Change Canada.
