The European Central Bank published a working paper examining whether euro area banks factor pollution-induced biodiversity risks into corporate lending decisions. Using loan and emissions data covering 832 banks and around 5,000 major polluters, the authors find that banks have increasingly incorporated these risks into lending terms, mainly by tightening loan-to-value ratios and, in some cases, charging higher interest rate premia in line with European Union pollution and biodiversity protection legislation. The study derives firm-level biodiversity and climate exposure measures from plant-level pollutant releases and transfers, including a freshwater ecotoxicity indicator based on 91 pollutants, and links these to ECB AnaCredit loan data and firm financial characteristics. Lending conditions are most affected for firms with large pollution footprints near biodiversity-protected areas such as Natura 2000 and for polluters linked to Environmental Quality Standards failures in downstream surface waters, while premia are also observed in certain cases such as smaller polluters and longer-maturity or refinancing loans. Stronger pricing of proximity-related biodiversity risks is associated with banks’ adoption of biodiversity policies and public commitments to the Equator Principles, whereas pricing linked to downstream water quality failures is tied to regulatory risk.

European Central Bank working paper finds euro area banks increasingly price pollution driven biodiversity risks into corporate loans
The European Central Bank's working paper shows euro area banks increasingly consider pollution-induced biodiversity risks in lending. Using data from 832 banks and 5,000 major polluters, it reveals adjustments in loan-to-value ratios and interest rate premia, especially for firms polluting near biodiversity-protected areas. The findings highlight the influence of EU legislation and banks' biodiversity policies on lending terms.
