The iSTOXX® Europe 50 SD-KPI index aims to closely track the STOXX® Europe 50, but with a slightly over- and under-weighting of the index components based on three Sustainable Development Key Performance Indicators (SD-KPIs). These three SD-KPIs are important and material environmental, social and governance (ESG) indicators for business performance in different sectors. SD-KPI Standards have been developed by SD-M® GmbH supported by the German Federal Environment Ministry, global investors and analysts who influence EUR 2 trillion in assets, as well as the Sustainability Accounting Standards Board (SASB).
