Requirements and guidelines according to the GHG Protocol
Category 1.2 of the Greenhouse Gas (GHG) Protocol covers emissions from mobile combustion processes that take place within the operational boundaries of a company. This includes, among other things
Company vehicles (cars, vans, trucks, buses),
Construction machinery and work equipment with internal combustion engines,
forklift trucks and agricultural machinery,
ships, airplanes and other mobile means of transportation owned or operated by the company.
The GHG Protocol requires companies to record and document all direct emissions from the Incineration of fossil fuels by company-owned or operated mobile sources. 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. diesel, petrol, natural gas, kerosene, biofuels) must be recorded separately to ensure an accurate calculation of emissions.
Fuelconsumption measurement: Fuel consumption can be recorded using fuel bills, logbooks or telematics systems.
Emission factors: Use standardized emission factors from recognized sources such as the IPCC, national environmental authorities or company-specific calculations.
Data validation: Regular checks of the recorded data for precision and consistency.
Reporting period: Data should be collected for a defined reporting period (e.g. calendar year).
Units: Fuel consumption should be documented in a standardized unit (e.g. liters, m3, kg).
Recording in NetCero
Follow these steps to record mobile combustion emissions in NetCero:
Create activity: record new emission sources (e.g. company vehicles, construction equipment, company airplanes) as separate activities in the system.
Assign responsibility: Designate a responsible person to record and keep the data up to date.
Assign data entry object: Assign each activity to the correct corporate entity to ensure accurate consolidation and evaluation.
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 mobile Incineration
Example 1: Company vehicles
A company operates a fleet of several cars and vans. The annual fuel consumption is 200,000 liters of diesel. The emissions are calculated as follows:
CO2e = Consumption(liter) x emission factor (kgCO2e/liter)
If the emission factor for diesel is 2.68 kg CO2e/liter, this results in 536,000 kg CO2e (536 tons CO2e).
Example 2: Construction site vehicles
A construction company uses various construction machines that run on diesel. The annual diesel consumption is 50,000 liters. With an emission factor of 2.68 kg CO2e/liter, the emissions amount to
50,000 x 2.68 = 134,000 kgCO2e (134 tCO2e)
