LRT Training Materials and Test Environment
The ARB has created a set of training materials for the LRT that includes the development of user guidance materials for the latest version (v2.2) of the Reporting Tool. Also, recorded training videos are available on the LRT Homepage.For those who would first like to be able to familiarize themselves with the LCFS Reporting Tool, the Test version of the LRT system is available online. All regulated parties are welcome to register their organization and obtain an account to access the LCFS Test system. This system is maintained with the same applications running as the LRT production system, which is the official reporting system. Users can interact with the most up-to-date implementation of the LRT. All information submitted through the Test system is "For Test Purposes Only".
When using the Test (or Production) version of the Reporting Tool, you will see that it is set up basically as an accounting system that either adds or reduces the “obligation” based on the type of fuel and business transactions. The system calculates the overall credit/deficit for the quarter based on the CI, volume, and fuel transaction type. On an annual basis, when reports from all four quarters are submitted, the system provides users the ability to review these submittals and submit an annual report based on the four quartler reports. The results are used to determine compliance (on the Production System). Back to top
