Calculating our overall footprint

The emissions generated by the activities of EDF Luminus in Belgium totalled 6,091 kilotons of CO2-equivalent in 2017, a decrease of 1% compared to 2016*. This evolution of the 2017 footprint components are due to:

  • the winter being less cold than the previous one
  • the increase in electricity output from natural gas-fuelled thermal plants.

The emissions directly linked to the company’s own electricity production (scope 1) made up 17% of the total footprint, compared to 13% the previous year. The emissions linked to the sale of gas to end-customers (scope 3) made up 54% of the overall footprint, compared to 55% in 2016.

*after restating the 2016 data, in particular regarding the methodology for calculating the emissions linked to infrastructure and equipment, and without taking into account a difference in methodology in the calculations of the emissions linked to the purchase of electricity (see note on methodology below, at the end of the page). 

Scope 1: Carbon footprint grew due to the increase in thermal production

  Scope 1: Directe emissies gegenereerd door de activiteit van het bedrijf (kt CO2e)

Scope 1 emissions rose sharply (+43%, to 956 ktCO2e), due to the more frequent recourse to the thermal plants in 2017 (cfr. Energymix).

Total emissions from the car fleet dropped slightly due to the decreased number of kilometres driven and the improved energy efficiency of the car fleet.

There were no SF6emissions generated in 2017.

Scope 2: Decrease in electricity consumption in company buildings

Scope 2 emissions fell by 16%, reflecting the lower electricity consumption in the company’s buildings.


Using the “market approach”, scope 2 emissions rose 12% due to the increase in the 2017 carbon intensity (from 117 to 155 gCO2/kWh) in EDF Luminus’ energy mix, which provides the electricity for all of the buildings concerned.

Scope 2: Indirect emissions generated by electricity that is consumed in buildings (ktCO2e)

Scope 3: Carbon footprint decreased slightly

  Scope 3: Indirect emissions from activities not included in scopes 1 and 2 (ktCO2e)

Source: Climact.

N.B. The GHG Protocol includes in scope 3 the carbon footprint associated with waste treatment and with the transport/distribution of the electricity sold. These two elements are not included in this graphic as they are extremely low (less than 0.5 ktCO2e.)

Ed: The scope 3 graphic published on page 46 of the 2016 sustainable development report included an error in units in the zoomed visual. The corrected version is presented above.

Overall scope 3 emissions fell slightly in 2017, due to the decrease in the volume of gas sold to end-customers (-3%) as well as the decrease in the volume of electricity purchased for resale to end-customers.

The infrastructure and equipment segment rose 10%, primarily due to the increased depreciation of the nuclear plants.

Note on the 2017 methodology:

The graphic above cannot be precisely compared to the carbon footprint for the segment “Electricity purchased for resale” over three years, due to a change in methodology in 2017.

Specifically, the emissions for all the electricity purchased in 2017, excluding nuclear power, were calculated based on the average emission factor of the Belgian network (197 gCO2 / MWh, according to IEA2016). In 2015 and 2016, it was possible to distinguish electricity purchases from cogeneration or incineration, giving them a higher specific emission factor.

A more precise calculation of the carbon footprint for this segment will be published later, based on the availability of internal resources.
