Information Bulletin RLCF-024: Proxy Carbon Intensities

Last updated on September 29, 2026

Introduction

Under the Low Carbon Fuels Act (LCFA) the director can publish carbon intensities (CI) without application or invitation to a public website maintained by or on behalf of the minister for the following fuels:

  • CNG
  • Hydrogen
  • LNG, and 
  • Propane

For clarity, these published CIs will be referred to as proxy CIs. Proxy CIs allow suppliers that have limited lifecycle information to report under a CI that is more accurate than the default CI, without requiring a CI application as is required for other published CIs (fuel codes).

Documentation requirements

Suppliers are required to submit the following documentation with their compliance reports, to use proxy CIs:

  1. A letter detailing how they determined the volumes associated with each proxy CI, and
  2. Documentation used to determine the volumes which could include:

a.  Records

b.  Invoices

c.  Contracts, and/or

d.  Purchase agreements

Approved proxy CIs

Table 1 lists approved proxy CIs and details the fuel pathway requirements to report fuel supply under them.
