The term scenario is widely used in different ways and contexts, making it necessary to arrive at a common understanding of how the term is used. Based on the OpenNESS Glossary, scenarios are defined as "plausible, but simplified descriptions of how the future may develop, based on a coherent and internally consistent set of assumptions about key driving forces and relationships. Scenarios are no predictions of what will happen, but ore projections on what might happen or could happen given certain assumptions about which there might be great uncertainty".
