SIX and Greenonomy have launched a sustainability assessment solution for small- and medium-sized enterprises (SMEs). The solution uses Greenonomy's software-as-a-service platform to provide global banking clients with a view of their SME clients' sustainability performances. Users can also define SMEs' sustainability transition trajectories and calculate the EU's Banking Book Taxonomy Alignment Ration (EU BTAR), which indicates the degree to which a bank's loan book is exposed to SMEs aligned with EU sustainability directives. The companies aim to offer a one-stop-shop service to banks, reducing operational costs and providing comprehensive sustainability assessments of SMEs. SIX's head of financial information and executive board member, Marion Leslie, emphasizes the importance of understanding the climate credentials of SMEs, as they represent 90% of businesses worldwide and 99% of the EU's economy.
