STEPforGGR is a research and training focused initiative consisting of world-leading institutions in the multidisciplinary and intersectoral subject areas of physics, chemistry, engineering and manufacturing. The overarching purpose is to promote a novel greenhouse gas removal technology: removal of non-CO2 greenhouse gases utilising large-scale atmospheric photocatalysis enabled by solar up-draft towers. The objective is to collaboratively evaluate the feasibility of this new but entirely untested negative emission technology and build up a foundation for climate policy debate and practical application tackling climate change at the global scale.
