Greenhouse gas emissions in Turkey's energy-intensive sectors have been analyzed from 1998 to 2017. The study used a method called Logarithmic Mean Divisia Index to break down the changes in CO2 emissions into five factors. The results show that economic activity and energy intensity play a crucial role in determining CO2 emissions. While economic activity has increased emissions, energy intensity has decreased. This suggests that reducing energy intensity could be the main factor in lowering greenhouse gas emissions in these sectors. Turkey needs to focus on adopting low carbon growth policies to reduce energy-related emissions and combat climate change.
