This page catalogs 763 technology and innovation projects on Keys for Tomorrow where sustainability is the core problem being solved, not a side feature. Coverage spans IoT and smart-monitoring hardware, digital twin simulation tools, refurbished and circular electronics, and climate-tech startups.Examples from the directory include AirShaper (automated aerodynamics simulation to cut vehicle emissions), Back2Buzz (refurbished smartphones and accessories), REDZone (IoT space-utilization sensors), and ShipReality (3D digital twins for maritime operations). The Clean Technology and Data & AI sub-categories narrow this to specific technology types.This category maps closely to SDG 9 (industry, innovation and infrastructure), since most projects here exist to make an industrial or consumer process measurably more resource-efficient.
