Fuel use covers Direct (Scope 1) emissions from the combustion of solid, liquid or gaseous fuel in company facilities e.g. for use of heating, in boilers, combustion turbines, process heaters and incinerators. Fuel sources can be purchased or generated by the company and include Natural gas, liquified petroleum gas (LPG), gas oil (aka red diesel), and coal products. Fuel consumption is reported, and common data sources are in-site meters and purchase records.

Emissions overview

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.

How to report emissions on Cozero

The activity data required for this calculation includes the amount of fuel consumed for each of the stationary combustion sources and the fuel characteristics of each type of fuel used.

To calculate fuel consumed, users can collect data of fuel consumed for combustion purposes. This is often calculated from

  • On-site metering: The mass or volume flow of fuel at the input point to one or more combustion units. These data can be gathered using measurement equipment such as scales or flow meters.
  • Purchase records: The mass or volume of fuel entering the facility. These data can be based on fuel receipts, purchase records or data provided directly from the energy vendor and /or customer online portal.

The following fuels can be entered; Diesel, fuel oil, Gasoline, hard coal, Lignite and Natural Gas. For all categories, the user can directly enter CO2 data for these fuel sources, or for additional sources.

Emission calculation

To calculate GHG emissions from company fuel 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 litre 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 CO2e value directly.
