Energy consumption data are reported for electricity and primary fuel sources, including natural gas, diesel, LPG, heavy fuel oil and steam. Electricity and natural gas data are obtained from supplier meters and reconciled with internal meters (when available) and/or service provider invoices. Diesel, LPG, steam and fuel oil consumption data are obtained from supplier invoices. CCI Operations used the following published conversion factors:
Extrapolation Method Used for Energy Use Calculation and Total Energy Consumption
Since the period covered by invoices may not always fully align with The Company’s reporting period, adjustments are made where necessary in order to align the consumption data from the invoices with the reporting period as agreed with The Company’s verifiers.
TCCC Default Factors for CO2 Emissions
Natural gas (MJ): 2
Diesel (MJ, light fuel oil):2
Heavy Fuel Oil (MJ):2
2012 IEA Factors (Used for the 2014 Report)
2013 IEA Factors (Used for the 2015 Report)
2015 IEA Factors (Used for the 2017 Report)
2014 IEA Factors (Used for the 2016 Report)
2016 IEA Factors (Used for the 2018 Report)
Water consumption data is obtained from internal meters where ground water is utilized. Moreover, separate data on water consumption is obtained from supplier meters and then reconciled with internal meters (when available) and/or service provider invoices where the water is supplied by the network.
The measuring and reporting of assured environmental data inevitably involves a degree of estimation. In exceptional circumstances, restatements of data reported in a prior year may be required. Restatements are considered where the data differs by more than 5% at The Company level.

GHG emissions are calculated by CCI using published conversion factors. Conversion factors enable an estimate of the amount of GHGs released into the atmosphere per unit of energy consumed. Different types of energy sources have different conversion factors that reflect their carbon dioxide intensity. In future periods, conversion factors may be updated to reflect changes to, and/or improvements in, published data. During the current period, the following conversion factors were used:
For fuels such as natural gas, diesel and LPG, conversion factors are derived from calculation tools based on the May 2015 version of the GHG Protocol Standards found on the GHG Protocol website (www.ghgprotocol.org). The Global Warming Potentials (GWPs) used to calculate the emissions of different GHGs in terms of CO2-equivalents are taken from the Intergovernmental Panel on Climate Change’s Fifth Assessment Report.
In 2014, we began using the “GHG emissions from transport or mobile sources” tool, version 2.6 of May 2015, from the GHG Protocol of the World Resources Institute and World Business Council for Sustainable Development to calculate the emission values for employee commuting and business categories. GHG emissions of Turkey are taken from the report verified by the auditing firm in line with the ISO 14064-1 Standard. Since 2017, we have been using DEFRA emission factors for diesel, managed vans class 3.
Natural gas (MJ): 0.05039 kg CO2
LPG (MJ): 0.0568 kg CO2
Diesel (MJ, light fuel oil): 0.0706 kg CO2
Heavy Fuel Oil (MJ): 0.0737 kg CO2 (Azerbaijan operations only)
