Abstract: The main aim of this study was to determine electricity utilisation based on the hourly distribution of CO₂ emissions. Turkey was chosen for this case study because of the CO₂ intensive characteristics of electricity generation. This study aims to be a pioneer in the spread of a time-varying carbon intensity approach for the calculation of carbon foot prints. Electricity generation-based hourly emissions are calculated by utilising actual data. It varies from 418.6 g CO₂/kWh to 824.6 g CO₂/kWh, or 597.8 g CO₂/kWh on average. According to hourly basis analyses, the highest CO₂ intensity of electricity generation occurs between 06:00 and 07:00. The highest CO₂ intensity of electricity generation occurs on a Sunday despite this being the time of lowest electricity demand. An annual total of 162.84 metric tons of CO₂ is released into the atmosphere as a result of electricity generation. Electricity generation-based CO₂ emission per capita is calculated as 2.04 ton CO₂.

Keywords: electricity generation; CO₂ intensity of electricity generation; CO₂ emission per capita; global warming; demand-side management; time-varying carbon intensity; Turkey.
