Registration requirements
See the Determining a Reporting Obligation page to find out if your operation has to report emissions.
Operators with a requirement to report emissions must register for emission reporting. They must also register for the B.C. Output Based Pricing System (B.C. OBPS).
Registering in BCIERS
The process to register is outlined below.
Step 1: Obtain a Business BCeID
A Business British Columbia Electronic Identification (BCeID) is required to register in BCIERS. This Business BCeID name must match the legal name of the operator being registered. Personal and Basic BCeIDs cannot be used to access BCIERS.
Search the BCeID business directory to check if your organization already has a Business BCeID. If not use the instructions and support to apply for one.
Contact the BCeID team if you have technical issues during the application process.
Step 2: Register in BCIERS
Use your Business BCeID to access the BC Industrial Emission Reporting System (BCIERS) and register your operator, operation, and facilities.

The following resources may be needed during the registration process:
After you register in BCIERS, the Province may assign unique identifiers to the operation and its facilities. These may include a BCGHG ID and a BORO ID, if applicable.
Forecasting emissions
Operations that have not reported emissions before
If an operation emits less than 10,000 tonnes of carbon dioxide equivalent ( CO2e), it must make an emissions forecast. The forecast must show if their emissions could go over this limit in the reporting period. Operators must forecast their emissions by no later than February 28 of the reporting period.
Registering as a potential Reporting Operation
If an operation forecasts emissions over 10,000 tonnes of CO2e n the reporting period, it must register as a Potential Reporting Operation in BCIERS by May 31.
If an operator first forecasts less than 10,000 tonnes of CO2e, it does not need to register during the reporting period. After February 28, the operator may determine emissions will reach 10,000 tonnes or more. In that case, it must register as a Potential Reporting Operation in BCIERS. Registration must occur within 90 days of that determination date.
Biomass emissions and the forecast threshold
Carbon dioxide produced from biomass listed in Item 1 of Schedule C of the Greenhouse Gas Emission Reporting Regulation must be reported. However, these emissions are not counted when checking forecasted emissions. The are excluded from the 10,000 tonnes of CO2e threshold.
Operations that are designated as opted-in do not need to forecast their emissions.
Reporting events that change registration information
Operators must report certain events that pertain to their operation or facilities within 30 days of the event occurring. The events that must be reported are:
- A closing or temporary shutdown
- An acquisition or divestment
- A change in the operator having control and direction, or a transfer of control or direction to the operator
- The start-up of a new facility
To report any of these events, complete and submit a Reporting Events Form.
