Fuel Energy and CO2 Emissions
The reporting of fuel consumption in the Protocol Spreadsheet is separate for kiln and non-kiln fuels.
- Kiln fuels are all fuels used in and for the clinker production process. This means those fuels fed to the kiln system plus fuels that are used for the drying or processing of raw materials for the production of clinker and the preparation of other kiln fuels.
- Non-kiln fuels are all other fuels used in the plant, which are not included in the definition of kiln fuels. For instance fuels used for plant and quarry vehicles, room heating, thermal process equipment (e.g. dryers) for the preparation of mineral components for cement grinding or in an installation separate from the kiln for on-site production of electrical power.
This separation is relevant for assessing the fuel and energy consumption of clinker production and the definition of several KPIs of the Cement CO2 and Energy Protocol.
The Protocol Guidance Document (Chapters 3.7, 3.8 and 5) provides more detailed guidance for reporting kiln and non-kiln fuels.
The Protocol considers a number of different fuel categories and corresponding fuel parameters, which should be determined at plant level. Please see the description for these tasks in the corresponding sub-topics.
