The aim of this study is to examine how greenhouse gas emission disclosures have evolved over time. The analysis was conducted using greenhouse gas emission data covering the period from 2015 to 2023 for 11 banks listed on Borsa Istanbul (BIST). In the study, greenhouse gas emissions were examined under the headings of scope 1, scope 2, scope 1+scope 2, and scope 3 emissions and total emissions according to banks, years, ratio to total assets and annual changes. According to the findings, scope 2 emissions have decreased significantly since 2020. However, it was concluded that the averages obtained as a result of the ratio of emissions to total assets exhibited a decreasing trend in all emission types since the beginning of the analysis period. On average, the largest decrease was found to occur in 2020 for scope 1 emissions and total emissions, and in 2021 for scope 2 and scope 3 emissions.
