1. The following Global Warming Potential (GWP) coefficients were used: 1 for CO2, 28 for CH4 and 265 for N2O. For further details see: IPCC, 2014: Climate Change 2014: Synthesis Report. Contribution of Working Groups I, II and III to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change.
The consolidation approach chosen was Operational Control.
The calculations and methodologies followed to estimate direct (Scope 1) GHG emissions were in accordance with the standards GRI 305 and GHG Protocol.
Methodologies used to calculate direct (Scope 1) GHG emissions were based on:
- site-specific data, more specifically the fuel consumed for stationary and mobile purposes and
- on published criteria, more specifically emission factors sourced from DEFRA and EPA and Global Warming Potential (GWP) coefficients.
Fuel consumption was converted to energy using the conversion factors sourced by the state offical documents (Regulatory Administrative Act 315/2019).
2. Fuel consumption was converted to energy using the conversion factors sourced by the state offical documents (Regulatory Administrative Act 315/2019).
3. Total energy consumption within the Organisation from fuels and electricity per Petabyte.
4. Intesity ratios were based on total GHG emissions of CO2 (Scope 1 & 2) per Petabyte.
