The GEF SGP CSO Innovation Challenge Program has opened its 2026 call for proposals, and it is aimed squarely at civil society organisations that already have a working environmental solution and now need the resources to replicate, expand or scale it. The programme is led by IUCN, with RTI International serving as the Lead Executing Agency, and it sits under the Global Environment Facility's Small Grants Programme.
Unlike a typical seed grant for untested ideas, this call is explicit about wanting proven models. Basic research and pilots that have not yet demonstrated results are not what the panel is looking for.
Key Details
Grants go up to $300,000 USD per organisation, alongside technical and institutional support, and finalists also receive programmatic support designed to help them attract further financing after the grant period ends. Projects can be subnational, national, regional or global in scope, but every proposal has to fit under one of five GEF SGP priority areas:
1. Community based management of threatened ecosystems and species
2. Sustainable agriculture, fisheries and food security
3. Low carbon energy access
4. Chemicals and waste management
5. Sustainable urban solutions
Project duration is capped at 24 months from the date the grant agreement is signed. Contracts are expected to be signed by December 2026, with projects starting in early 2027, and any costs incurred before that official start date will not be reimbursed.
Applications are only accepted through the programme website, csochallenge.org, and can be submitted in English, French or Spanish, with reference templates available in each language. Deadlines are set per regional call and announced at launch, so applicants need to check the website for the date that applies to them rather than assume a single global cutoff.
Eligibility Requirements
Eligible applicants are local, national, regional or international civil society organisations that are legally authorised to receive charitable contributions from foreign sources, hold a bank account in the organisation's own name, and will be directly responsible for implementing the project. International CSOs can apply, but only if they work closely with national stakeholders and local communities and secure all the government authorisations that involves.
Governments may take part in project activities but cannot receive grant funds directly. Proposals led by, or with strong involvement from, youth, women and Indigenous Peoples are specifically encouraged, and the initiative being replicated or scaled must be based in a GEF SGP eligible recipient country.
A lead partner can apply alone or bring in co-applicants, and may submit up to two proposals as lead partner, though only one of those can ultimately be funded. There is no limit on how many applications an organisation can join as a co-applicant. Current employees of IUCN or the GEF, and their immediate family members, are barred from applying due to conflict of interest rules.
What It Covers
The programme funds activities built around replication and scale rather than experimentation. That includes pilot expansion, capacity building, toolkits and guides, policy advocacy, new partnerships, seed funding, awareness campaigns, technology transfer with attention to protecting the innovator's IP, and community peer learning networks.
It also supports the groundwork needed to make scaling credible: feasibility and financial viability analysis such as cost benefit work and cash flow modelling, environmental and social safeguards documents like ESMPs and protected area management plans, and applied research, provided that research is aimed at optimising the solution and produces results within the project timeframe. Pure research and conservation planning are explicitly ruled out, as is any funding passed on to third parties through sub-grants.
On the budget side, eligible cost categories are personnel, subcontracting, supplies, equipment and maintenance, travel, meetings and workshops, and indirect costs capped at 7% of direct costs. Any single cost over $20,000 requires three quotations from different suppliers on file. Co-financing is not mandatory, but the guidance is direct about it strengthening a proposal, since the programme wants to see that a solution can attract further public, private or philanthropic investment beyond the grant itself.
Application Process
The process runs in five stages. Applicants submit a Concept Note, which goes through an eligibility screening against the criteria above, then a review by two assigned members of the Selection Committee. Based on those scores, the highest scoring group of 20 to 25 proposals is invited to submit a Full Proposal, which is reviewed by a second panel of two reviewers. The top 12 from that round go to the Selection Committee, chaired by the GEF Secretariat and including IUCN, GEF partners and civil society representatives, which meets to select six winners. IUCN recuses itself from any vote involving its own members.
The Concept Note itself covers applicant information, eligibility, a project overview with executive summary and budget outline, a full project description including objective, theory of change, rationale, components and activities, expected impact and risks, a KBA assessment for any activity near a Key Biodiversity Area, preliminary stakeholder identification, the project budget, the applicant's relevant experience and key personnel, and a preliminary environmental and social risk screening.
Reviewers score against five criteria: priority area alignment, impact potential, scalability and sustainability, feasibility and organisational capacity, and inclusion and partnerships. The guidance is consistent on one point throughout, that the theory of change should work backwards from the environmental outcome you want, naming who needs to change behaviour, what they will do differently, and why, rather than simply listing activities.
Required documents at this stage include the organisation's Articles of Incorporation or equivalent registration document, an in-country registration certificate where applicable, a location map, and CVs of key project staff. Partner confirmation letters can be uploaded separately, and additional documents may be requested if a proposal is shortlisted.
Major Considerations
The full review and award process takes about three months after the Concept Note deadline, and shortlisted applicants then move into a technical and ESMS refinement process with IUCN that can run another one to five months before a grant agreement is signed. Applicants should plan on roughly six months between submitting a Concept Note and a project actually starting, which matters for any organisation trying to line up co-financing or staff around a specific start date.
Questions about the call need to go to the programme email within 15 days of the regional launch, and answers get posted to the FAQ page on the website, which is worth checking before writing in.
Should You Apply?
This is a strong fit for CSOs that have already run a solution successfully at a smaller scale, whether that is a restoration model, a livelihoods programme, a waste management scheme or a community energy project, and now need capital and technical backing to take it further.
It is not the right call for an organisation still testing an idea for the first time, since the guidance is explicit that basic research and untested pilots fall outside what the programme wants to fund. Organisations with a documented track record, a realistic budget tied to specific activities, and genuine partnerships already in place with the communities they work with are the ones the criteria are built to reward.
