Direct (scope 1) emissions from the combustion of fuel in owned or leased mobile sources (both on-road and non-road vehicles) that are within the company’s inventory boundaries. Fuels consumption can be reported, or estimated from mileage data per vehicle type.
Scope of emissions source
Scope 1 emissions are direct emissions from company-owned and controlled resources. In other words, emissions released to the atmosphere as a direct result of a set of activities, at a firm level.
Scope 1 owned vehicle emissions refer to a wide variety of company-owned or operated vehicles, engines and equipment that generate GHG emissions through the combustion of various fuels while moving from one location to another. They include vehicles used on roads for transportation of employees or distribution trucks as well as off-road vehicles, engines and equipment used for many other purposes.
Typically, these will be cars, vans, trucks and motorcycles powered by petrol or diesel engines. However, transport is changing. Alternative fuels, such as liquid petroleum gas (LPG) and liquefied natural gas (LNG) are being adopted, as are the biofuels; bio-diesel and bio-ethanol. Full electric vehicles (EVs) and plug-in hybrids (PHEVs) are also becoming more popular. The increasing use of electric vehicles could mean that some of an organisation’s fleet will fall into Scope 2 emissions.
How to report emissions on Cozero
GHG emissions from mobile combustion are most easily estimated by collecting data on the amount of fuel consumed, distance traveled and vehicle and fuel characteristics for each identified source.
This module covers vehicle fleet only. There are two methods for activity data collection.
- Consumption-based module - This method as described in the GHG Protocol Scope 3 Guidance is used to calculate these emissions involves determining the amount of fuel consumed (i.e., scope 1 and scope 2 emissions of transport providers).
- Mileage-based module - This method as described in the GHG Protocol Scope 3 Guidance is used to calculate these emissions involves distance, mode and fuel type of the vehicle fleet.
For all modules, the user can also directly enter CO2 data.
To calculate GHG emissions from company data, Cozero applies an emission factor. An emission factor is a coefficient which allows to convert activity data into GHG emissions. It is the average emission rate of a given source, relative to units of activity or process/processes (e.g., kg CO2e emitted per liter of fuel consumed, kg CO2e emitted per kilometer traveled, etc.)
Fuel consumption * emission factor = CO2 equivalent (CO2e) emissions
The user can add their own emission factors when entering data into Log. Alternatively, the user can enter a CO2 value directly. For additional information on the calculation of emissions from purchased goods and services, users can refer to the GHG Protocol Guidance.
