A new working aid on the Local Sustainability Reporting Framework (BNK) has been published, supplementing the BNK Guidance Document 2.0. The BNK can be understood as a practical guide for municipal sustainability reporting, designed to support local authorities in creating sustainability reporting in a practical and efficient manner, to standardise processes, and simultaneously, offer flexibility to accommodate individual municipal needs. Dr. Anke Butscher, managing partner at corsus, worked jointly with Julia Pfinder to comprehensively develop the content and structure of the working aid on behalf of the German Council for Sustainable Development (RNE).
