delegates at the Tanzania Green Summit 2026
Climate ambition. Practical action.
Grina Foundation is a centre of opportunity for climate action and financing, turning green businesses into bankable enterprises and bringing financiers, policymakers and communities together to act.
Why we exist.
Closing the gap between green ideas and opportunity.
Tanzania has green entrepreneurs with real solutions, and climate finance looking for them. Too often the two never meet.
Grina exists to close that gap: turning early-stage green businesses into bankable, investable enterprises, and staying alongside them as they grow. We also work with communities and local partners to turn climate priorities into practical action.
Our principle is simple: globally recognized, locally relevant.Why GrinaWhat we do.
