Comparative assessment of carbon footprints of selected organizations: The application of the enhanced bilan carbone model

Abstract

Making organizations aware of their carbon footprint (CF) and proposing measures to reduce it are important segments of climate change mitigation. As a part of this process, an enhanced Bilan Carbone model with incorporated country-specific greenhouse gas (GHG) emission factors was applied for CF calculations of three organizations (Agency, Faculty, and Institute). The model, fully in line with international CF calculation standards, can be applied to calculate the CF of any organization on the global level. The paper provides a comparative assessment of CFs of considered organizations and preconditions for a reliable comparison. The calculated CFs values for 2017 were 513.4 t CO2 e for the Agency, 4254.7 t CO2 e for the Faculty, and 477.0 t CO2 e for the Institute. Comparing specific CF, the Faculty had the highest value per employee (9.4 t CO2 e/employee) and the lowest value per heated area (131 kg CO2 e/m2), followed by the Institute (5.4 t CO2 e/employee and 222 kg CO2 e/m2) and the Agency (4.5 t CO2 e/employee and 294 kg CO2 e/m2). Using the enhanced Bilan Carbone model, adapted to national conditions, could lead to the harmonization of the organizations’ CF calculation and enable the identification of significant emission sources. This will facilitate the definition of GHG reduction targets and the identification of mitigation measures for achieving the targets, as presented in the example of the Institute.
