Clean Fuel Regulations: Update for Biogas and Renewable Natural Gas Pathways

Environment and Climate Change Canada (ECCC) released an updated Fuel LCA Model Database. This correction addresses modelling for biogas and renewable natural gas (RNG) pathways. If your projects involve biogas or RNG as an input or feedstock, use the latest version for accurate carbon intensity (CI) calculations.

Key Points:

  • The update does not impact the Specifications for Fuel LCA Model CI Calculations or the CFR Data Workbook published on June 28, 2024.
  • For pathways not involving biogas or RNG modelled with the June 2024 database, you may still submit a CI application using that version, but switching to the August 2024 database is recommended.
  • Any modelling of biogas or RNG using the June 2024 database will not be approved.

For more information, contact ECCC at cfsncp@ec.gc.ca.

Description of corrections:

1. In the Other inputs for biogas production folder in the Biogas pathway folder of the Fuel Pathways, the units of the reference flow for each of the following processes has have been changed from mass (kg) to energy (MJ):

  • “Direct emissions, digestate storage, per MJ of biogas”
  • “Direct emissions, digester leakage, per MJ of biogas”

 

2. In the Other inputs for RNG production folder in the Renewable natural gas pathway folder of the Fuel Pathways, the units of the reference flow for each of the following processes has have been changed from mass (kg) to energy (MJ):

  • “Direct emissions, digestate storage, per MJ of RNG”
  • “Direct emissions, digester leakage, per MJ of RNG”
  • “Direct emissions, fugitive emissions, per MJ of RNG”

 

3. In the folder Predefined transport scenarios in the Transport folder of the Data Library, the following processes were deleted because they are not used in any programs:

  • “RNG (gaseous) feedstock transport to hydrogen plant (High-impact scenario)”
  • “RNG (gaseous) feedstock transport to hydrogen plant (Low-impact scenario)”
  • “RNG (liquid) feedstock transport to hydrogen plant (High-impact scenario)”
  • “RNG (liquid) feedstock transport to hydrogen plant (Low-impact scenario)”
