Tanzania Green Summit
Our annual flagship gathering, where green businesses, financiers and policymakers meet, and where deals begin in the Business Deal Room.
Explore the SummitClimate ambition. Practical action.
We connect green businesses, communities and partners to turn climate ambition into action.
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.
