This research investigates the function of corporate governance in enhancing the application of ESG (Environmental, Social, and Governance) within Uzbekistan’s commercial banking industry. This research employs secondary data from sustainability reports, annual disclosures, and publications by the Central Bank of Uzbekistan and international financial institutions to critically examine the impact of governance structures-such as board independence, gender diversity, and oversight committees-on ESG integration and financial stability. The results show that more and more Uzbek banks are reporting on ESG issues. In 2019, just two banks did this, but by 2024, eight banks will be doing it. Banks with boards that are more independent and diverse show far better ESG performance and financial strength, which is shown by greater returns on assets and fewer loans that are not performing. The paper also points out ongoing problems, such as a lack of ESG knowledge, no standardised reporting standards, and uneven policy implementation. The study finds that corporate governance is both a base and a force behind sustainable finance. To bring Uzbekistan's banking practices in line with global sustainability standards, it calls for a national ESG disclosure standard, more accountability at the board level, and stronger institutional capacity building.
