Banks, as institutions that are profit-oriented and play a role in development and the economy, must also pay attention to environmental and community aspects to maintain sustainability in the long term. Banking and the environment are two different things, even opposites. Banks are commercial entities, whereas the environment is not. Despite their significant differences, these two concepts interact as a sustainable chain, leading to the integration of environmental and social management aspects in financial reports, which are essential for achieving sustainability. McKinsey's 2020 suggests that digital transformation implementation can boost productivity and optimize banking capital and implementing digital transformation will reduce bank operational costs by at least 30 to 40 percent. This will certainly increase the efficiency of the banking sector itself. Therefore, the objective of this research is to empirically test and analysis the effect of green banking, digital transformation, asset quality, on the financial performance of commercial banks with foreign ownership as a moderator, and test and analysis the financial performance on sustainable business for commercial banks. This research conducted on commercial banks that classify bank groups based on core capital 3 and 4, which are listed on the Indonesia Stock Exchange, covering the period from 2017 to 2022. This research employed a saturated sample sampling technique, encompassing a total of forty-seven conventional commercial banks. Panel data regression analysis, a data analysis technique, employs three variables: the dependent variable, the independent variable, and the moderation variable. The research reveals that green banking and digital transformation significantly improve the financial performance of Indonesian commercial banks. In addition, asset quality, as measured by non-performing loans, does not affect performance. Whereas foreign ownership can strengthen the influence of green banking and digital transformation on financial performance, it does not moderate the influence of capital adequacy on financial performance. Finally, high financial performance positively impacts sustainable business, indicating that a bank's sustainability can be positively influenced by its financial performance.
