The implementation of the EU taxonomy in the credit business as well as climate-related credit risk management require a plethora of new data points which are hardly available in financial institutions at the moment. In particular in the real estate mortgage business, access to crucial data points like the energy efficiency of buildings or precise flooding risk assessment is key for compliance with the EU taxonomy, reducing risks, but also for transitioning the financed real estate portfolio to net-zero emissions. In this real-life case study we show how to solve one of the data challenges in an efficient and effective manner by tapping into the potential provided by new data services derived from satellite imagery and large-scale satellite constellations, which are currently growing in low earth orbit.
