4. Method for Fuel Use to Carbon Dioxide Emissions Estimations
The following table shows the approximate amount of fuel that, when fully combusted, would result in 25,000 and 2,500 metric tonnes of CO2 for selected common fuel types.
The 25,000 metric tonne threshold is the level at or above which general stationary sources of combustion are required to report under the regulation. Similarly, the 2,500 metric tonne threshold is the level at or above which electricity generating facilities >1MW are required to report. This information is provided to give operators a rough estimate of whether or not a given facility falls within the scope of ARB’s mandatory reporting program. However, this table alone may not be used to demonstrate that a facility has no reporting obligation.
These tables are based on the ARB accepted emission factors which are set forth in this document. If an operator is combusting multiple fuels types, or is using a fuel type not listed in this table, then the operator must multiply the amount of fuel consumed annually for each fuel type by the ARB provided emission factor and sum the emissions to determine annual CO2 emissions from stationary combustion.
