Biotechnology is a high-growth area that has significant potential for greenhouse gas removal. Homeworld Collective identified that risk-tolerant funding and interaction between teams have been limiting factors to the deployment of this new approach to sustainability challenges.
The Garden Grants program facilitates learning and collaboration by publicly discussing important problems for climate while protecting applicants’ novel approaches.
Proposals to Homeworld Garden Grants have two main sections: the problem statement (3,000 characters) and the solution statement (10,000 characters). The Proposal Guidelines and Template document provides detailed instructions for completing your applicaiton.
Proposals may address problems identified by applicants, or pre-written problems originating from our Problem Statement Repository.
