Calculation Method:
The upper threshold of the average values provided in the article on Carbon Emission Calculation Methodology published by the ICAO – International Civil Aviation Organization has been taken as the basis. A Boeing 737 consumes between 2.6 and 3.7 liters of jet fuel per kilometer. The calculation is based on 3.7 liters. Each 1 liter of jet fuel produces 2.7 kg of CO₂, and the conversion of CO₂ to carbon has also been included in the calculation.
Calculation Method:
According to TEKMER regulations, an office with 300 employees must have at least 4 square meters per person, resulting in a total area of 1,200 m². An office of this size, heated with electricity, consumes an average of 11,500 kWh of electricity per year. Assuming that all of this electricity is generated from coal-fired power plants, this results in 12,540 kg of CO₂ emissions. When converted to carbon, this corresponds to a value of 3,420 kg.
Calculation Method:
According to Google’s Sustainability Report, in 2020, Google Cloud stated that it uses an average of 0.0000005 kWh of electricity per 1 GB of stored data. This corresponds to approximately 0.0000002 g of CO₂, which is equal to 0.000000005456 g of carbon. After converting terabytes to kilograms, this results in 0.000005592 kg of carbon per terabyte.
