Carbon intensities of fuels supplied in B.C. must be calculated using an approved version of the GHGenius model unless the Director has accepted an alternative method for some or all of the components of the fuel's lifecycle. The GHGenius model can be used to develop lifecycle assessments (LCAs) for transportation fuels used in Canada that are consistent with International Organization for Standardization (ISO) standards:

  • 14040: 2006 Environmental Management – Life cycle assessment – Principles and Framework
  • 14044: 2006 Environmental Management – Life cycle assessment – Requirements and guidelines

See RLCF011: Approved Version of GHGenius and Global Warming Potentials.

From January 1, 2024 onward, carbon intensity applications must be prepared using GHGenius version 5.02b.

For detailed instructions on how to use GHGenius to prepare a carbon intensity application, please refer to:
