Business as usual is a climate scenario that assumes continued fossil fuel use and limited climate action. It’s typically represented by SSP5-8.5 or RCP8.5, projecting global warming above 3°C by 2100.
Teams use EarthScan’s business-as-usual scenario to stress test how climate risks like flooding or heat stress might intensify without mitigation.
This scenario helps identify worst-case exposure, which is useful for resilience planning and required under disclosure frameworks like CSRD and TCFD.
