EDF Luminus has been measuring its carbon footprint since 2011, using the GHG (Greenhouse Gas) protocol. This is the most widely recognised method internationally for carbon accounting.
EDF Luminus complies with the GHG (Greenhouse Gas) standard for collecting data and for calculating its overall footprint. This methodology was developed at the initiative of the WRI (World Resource Institute) and the WBCSD (World Business Council for Sustainable Development) in consultation with companies, NGOs and governments.
The standard covers the six principal greenhouse gases: carbon dioxide (CO2 ), methane (CH4 ), nitrogen oxide (N2 O), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and Sulphur hexafluoride (SF6 ). The data are presented in tonnes of CO2 -equivalent (tCO2 e), with the other gases converted in accordance with their global warming potential.
The GHG Protocol classifies three «scopes» to enable companies to identify their emissions:
Note on methodology
The methodology for calculating the carbon footprint, carried out by Climact, is refined every year in order to comply with the most recent developments of the GHG protocol. When the calculation method is modified, the figures for the previous years are restated, in order to maintain a comparative base for the three illustrated years. Compared to the results communicated in the 2015 report, emissions linked to the electricity acquired from other producers are once again included (as in 2014 and 2013) based on the origin of the electricity (wind, solar, nuclear, cogeneration, incineration, etc.) This approach makes it possible to use the most recent emissions factors, as well as enabling the measurement of the real carbon intensity of the electricity acquired by EDF Luminus.
