For the statistical validation of the nature and significance of relationship between latent constructs, data was analysed using SMART PLS 4. Findings – The findings show that drivers of green fintech such as AIU, GF and SDI and its technologies, are a key to enhancing the performance of environmental sustainability, resource-efficiency and SG as well as soften sustainability oriented digital transformation within firms.
