Requirements and guidelines according to the GHG Protocol
Category 1.1 of the Greenhouse Gas (GHG) Protocol covers emissions from stationary combustion processes that take place within the operational boundaries of a company. These include, among others:
Boilers,
furnaces,
generators,
industrial processes using fossil fuels,
District heating power plants, provided they are operated by the company itself.
The GHG Protocol requires companies to systematically record and document all direct emissions from the Incineration of Fossil fuels. These emissions fall under Scope 1 (direct emissions) and must be calculated on the basis of fuel consumption and the corresponding emission factors.
Important requirements
Fuel types: All fuels used (e.g. natural gas, heating oil, coal, biomass) must be recorded separately to ensure an accurate calculation of emissions.
Consumption measurement: Fuel consumption should be recorded as accurately as possible. Companies should rely on direct measurements (e.g. by meters) or on reliable invoices and delivery reports.
Emission factors: Use standardized emission factors, either from recognized sources such as national environmental authorities or company-specific calculations.
Data validation: There should be regular checks of the data collected in order to identify errors or deviations at an early stage.
Reporting period: Data should be collected and documented consistently over a defined reporting period (e.g. a calendar year).
Units: Fuel consumption should be documented in a standardized unit (e.g. kWh, m3, liters or tons).
Recording in NetCero
Follow these steps to record combustion emissions in NetCero:
Create activity: record new emission sources (e.g. boiler, emergency generator, industrial furnace) as separate activities in the system.
Assign responsibility: Designate a responsible person to record the data and keep it accurate.
Assign recording object: Assign each activity to the correct business entity to ensure accurate consolidation and reporting.
Select emission factors: Users standardized emission factors from the NetCero database.
Define your own emission factors: Add company-specific factors if more accurate values are available.
Document fuel consumption: Record consumption directly in the table within the activity - based on measurements or estimates.
Automatic emission calculation: NetCero calculates the emissions per activity and integrates them into the overall balance.
Examples of emissions from stationary Incineration
Example 1: Boiler in an office building
A company operates a boiler that runs on natural gas to heat the company building. The annual natural gas consumption is 50,000 m3. The emissions are calculated with:
CO2e = consumption (volume) x emission factor (kgCO2e/m3)
If the emission factor is 2.0 kg CO2e/m3, this results in 100,000 kg CO2e (100 tons of CO2e).
Example 2: Emergency power generator in a production plant
A factory has an emergency power generator that runs on diesel. In the reporting year, 5,000 liters of diesel were consumed. If the emission factor for diesel is 2.68 kg CO2e/l, the emissions are
5,000 liters x 2.68 kgCO2e = 13,400 kgCO2e (13.4 tCO2e)
kg CO2e (13.4 tons CO2e).
Example 3: Industrial furnace in steel production
A steel producer operates an oven that is fired with coke. Accurate recording of coke consumption is necessary in order to correctly calculate the resulting emissions.
