Green transformation is a process of urban transformation that focuses on using renewable energy sources and green areas (e.g. environmental degradation) for cities' sustainable future. In recent decades, this dilemma has become a universal concern for humankind because of increasing daily needs, urbanisation, population, and economic growth to produce CO2 emissions. Thus, this paper seeks to provide an overview of the literature on green transformation and finance from various sources, summarises the results and makes conclusions based on the findings. This study's design is a qualitative method with mini-review through reading and analysing 30 journal articles. Green transformation and finance reviews were carried out by reading and analysing 30 peer-reviewed journal articles and summarised on the basis of the subject in two tables, namely article journal and publisher distribution, and article category. Using the mini-review analysis, we found that most companies in different countries implement different regulations and policies related to the environment to overcome this green transformation. It is undeniable that lenders are willing to invest their money to support companies that practise environmental sustainability awareness to implement the green transformation to loans. As a result, it is quite significant for companies and countries' performance that have policies and controls on the environment to implement and deploy green finance. In conclusion, this study found a role and government policies related to green finance in realising green transformation and firm performance.
