Transportation Fuel Lifecycle Assessment

A "fuel lifecycle" encompasses all of the stages of a fuel product's life from raw material to final use. A lifecycle assessment (LCA) considers the details of all those stages. The term "carbon intensity" refers to a single value that represents the sum of greenhouse gas emissions from the fuel lifecycle. For more information, see:

Carbon Intensity Approval

Low carbon fuel producers may apply to the director for approval of a fuel carbon intensity that has been determined in accordance with the requirements of the Renewable & Low Carbon Fuel Requirements Regulation.

Additional information about approvals:

Once a carbon intensity is approved, that fuel is assigned a unique fuel code which is used in the trading or sale of that fuel and for compliance reporting. For the current list of approved carbon intensities, see:


The carbon intensity of fuels supplied in B.C. must be calculated using the GHGenius model. The GHGenius model is a mature modelling approach that can be used to develop LCAs for transportation fuels used in Canada that are consistent with International Organization for Standardization (ISO) standards 14040 and 14044.

For determining the carbon intensity of all fuels supplied after January 1, 2015, the approved version of GHGenius is v4.03 as described in Approved Version of GHGenius (RLCF-011) (PDF, 103KB).

This guide - Using GHGenius in BC (RLCF-010) (PDF, 688.6KB) - supplements the existing GHGenius instruction manual. It provides working examples that illustrate the process of determining the carbon intensity of a transportation fuel.
