Carbon intensities of fuels supplied in BC 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, 2015 until December 31, 2023, carbon intensity applications must be prepared using GHGenius version 4.03, or in accordance with the Transition Plan. 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:
RLCF-010 supplements the instruction manual for GHGenius 4.03 and provides working examples that illustrate the process of determining the carbon intensity of a transportation fuel. The instruction manual for GHGenius 4.03 can be obtained by contacting Environment and Climate Change Canada (ECCC).
Starting January 1, 2024, the Low Carbon Fuel Standard will transition from GHGenius version 4.03 to version 5.02b as the approved model for calculating carbon intensities. All applications submitted after this date must be prepared using GHGenius 5.02b and any applications submitted prior to this that use GHGenius 4.03 will expire by June 30, 2024.
The following plan has been put in place to support this transition:
Below are examples of some possible scenarios to clarify the transition plan:
The Low Carbon Fuels Branch held an online GHGenius5.02 workshop series on November 14, 15 & 16, 2023. The workshop was led by Don O’Connor from (S&T)2 Consultants.
The content of the workshop was:
November 14 & 15 covered the main workshop content and November 16 was a Q&A session.
