OpenClimate.fund is an initiative by OpenSustain.tech and Ecosyste.ms focused on support for open-source climate and sustainability projects. Its published model connects adding a missing project to the OpenSustain.tech directory with nominating a different project to receive a donation. The goal is to improve discovery of useful environmental software while directing support toward work already in the ecosystem.
The launch announcement, dated December 18, 2024, describes an initial 10,000-euro pilot fund and 100-euro gifts. Contributors submit a missing project through the directory's review process, then choose another eligible project rather than their own. The announcement says the initial round focuses on projects active within the preceding six months that accept donations through known platforms. The homepage describes payment after the contribution is reviewed and merged.
This is a nomination and review model, not an automatic payment to the person submitting a project or an unrestricted grant application. The initial fund size is a description of the pilot, not evidence that money remains available today. Anyone considering a nomination should check the initiative's current round and contribution rules. The useful starting point is its explanation of how directory contributions and small donations can reinforce each other, with the linked repository and OpenSustain.tech resources providing the route into the project.
