The steps set out in this document enable a company to decide whether it wishes to make the transition to activities that deliver a Net Gain for Biodiversity (BNG) - or at least No Net Loss - and how to get there. This roadmap document does not give detailed directions, but an outline with links to more help. It is based on the Plan-Do-CheckAct Cycle that forms part of the ISO 9001 Quality Management System, as shown in Diagram 1. It does not seek to be prescriptive, understanding that different companies have different internal structures, products and relationships.
