The European Banking Authority (EBA) has published a roadmap for sustainable finance, which aims to better integrate ESG risk considerations into the banking sector. This will require banks to re-work their scoring criteria for green loans and mortgages, and potentially reassess existing loans with new data. The impact on banks will be significant, requiring them to collect more data from diverse sources and adapt their loan origination systems quickly. Banks will need to manage evolving changes, capture different data attributes, incorporate new data types and formats, find insights from the data explosion, meet customer demands, and provide real-time sustainability risk-adjusted credit scores. MongoDB can help banks by providing a simplified architecture for green loan origination, including features such as Atlas Device Sync, Atlas Search, Atlas Data API, Data Aggregation Pipeline, Atlas Charts, and Atlas Triggers, which enable flexible data management, search, analytics, and server-side logic execution.
