GEF SGP CSO Challenge Program: Grants of Up to $300,000 for Civil Society Organizations Leading Environmental Solutions

Civil society organizations (CSOs) working on climate change, biodiversity conservation, sustainable agriculture, ecosystem restoration, low-carbon development, pollution reduction, waste management, food security, and sustainable urban development have an opportunity to access significant funding through the GEF SGP CSO Challenge Program.

The program builds on the experience of the Global Environment Facility Small Grants Program (GEF SGP) and is designed to identify, recognize, and support innovative environmental solutions developed and implemented by civil society organizations and local actors.

Unlike traditional small-grant approaches, the CSO Challenge Program is intended for organizations that have already demonstrated technical and organizational capacity and have a proven record of achievement and impact. Successful applicants can receive grants of up to US$300,000 to support projects lasting up to 24 months.

The funding is particularly relevant to organizations seeking to take an existing environmental solution to the next level through replication, adaptation, scaling, and expanded impact.

Opportunity Overview

The GEF SGP CSO Challenge Program is an initiative focused on strengthening high-impact environmental action led by civil society organizations.

The program recognizes that communities and CSOs are often closest to the environmental challenges affecting their regions. These organizations frequently understand local ecosystems, livelihoods, cultural contexts, and community needs better than outside institutions. However, organizations with successful ideas may lack the financial resources needed to replicate or scale those solutions.

The CSO Challenge Program is intended to address this gap by providing larger grants and tailored support to organizations with demonstrated experience and promising approaches.

The program’s central objective is to:

Identify, reward, and support high-impact innovative environmental approaches and solutions spearheaded by civil society organizations and actors.

What Is the GEF SGP CSO Challenge Program?

The Global Environment Facility Small Grants Program (GEF SGP) has supported community-based environmental and conservation initiatives for decades.

The CSO Challenge Program builds upon that experience while introducing a funding approach aimed at organizations that are ready to move beyond individual community-level projects.

Rather than primarily supporting organizations at the earliest stages of development, the program targets CSOs that already have:

• Relevant technical expertise.
• Strong organizational capacity.
• Experience implementing environmental initiatives.
• Evidence of successful results.
• A demonstrated record of impact.
• An environmental solution or approach with potential for wider application.
• The ability to manage a larger grant.
• A clear pathway toward replication, adaptation, or scaling.

Through grants of up to US$300,000, the program provides an opportunity for established CSOs to expand solutions that have already demonstrated promise.

Funding Amount and Project Duration

Eligible organizations can apply for grants of up to:

US$300,000

Projects supported under the program can run for up to:

24 months

This funding level is significantly larger than traditional small grants and is intended to help organizations transition successful approaches from individual projects into broader initiatives capable of generating greater environmental and community impact.

Applicants should therefore demonstrate not simply that their project is important, but also why additional investment is necessary and how the proposed funding will contribute to measurable growth, replication, adaptation, or scaling.

What Types of Projects Does the Program Fund?

The CSO Challenge Program supports initiatives that can demonstrate potential for wider environmental impact.

In particular, funding can support organizations seeking to:

1. Replicate Proven Models

Organizations can seek funding to reproduce an environmental solution that has already demonstrated success in one community, ecosystem, location, or context.

Replication may involve taking an existing model and introducing it to:

• New communities.
• New geographic areas.
• New ecosystems.
• Similar environmental contexts.
• Different local or national settings.

The applicant should be able to demonstrate why the existing model is successful and why it has potential to work in the proposed new setting.

2. Adapt Existing Solutions

Environmental solutions do not always work identically in every location.

The program therefore supports efforts to adapt proven approaches to local circumstances, including differences in:

• Ecosystems.
• Climate conditions.
• Community needs.
• Local economies.
• Governance structures.
• Cultural practices.
• Natural-resource availability.
• Livelihood systems.

An organization may therefore propose to modify an existing successful approach so that it becomes effective in a different local context.

3. Test Scaling Approaches

The program also supports organizations seeking to determine how a promising environmental innovation can be expanded.

Scaling can involve increasing the number of communities reached, expanding geographic coverage, reaching additional beneficiaries, strengthening implementation systems, or developing partnerships that allow an established solution to reach a substantially larger population.

The emphasis is on moving beyond isolated success toward approaches that can generate broader and more sustainable environmental outcomes.

Five Strategic Priority Areas

The program welcomes applications from CSOs working in five strategic areas.

1. Community-Based Management of Threatened Ecosystems and Species

This priority area focuses on empowering communities to protect, restore, and sustainably manage ecosystems and species facing environmental pressure.

Potential initiatives may involve:

• Biodiversity conservation.
• Habitat restoration.
• Community-based conservation.
• Protection of threatened species.
• Ecosystem restoration.
• Sustainable natural-resource management.
• Community stewardship of important ecosystems.
• Conservation initiatives involving local communities.

The program recognizes that communities can play an important role in protecting biodiversity when they have the knowledge, resources, partnerships, and incentives required to manage natural resources sustainably.

2. Sustainable Agriculture and Fisheries and Food Security

The program also supports approaches that connect environmental sustainability with food production and community livelihoods.

Relevant initiatives may address:

• Sustainable agriculture.
• Sustainable fisheries.
• Food security.
• Natural-resource conservation.
• Climate-resilient food systems.
• Sustainable production practices.
• Community-based fisheries management.
• Agricultural approaches that protect ecosystems.

Projects should demonstrate how environmental protection can be integrated with sustainable livelihoods and food production.

3. Low-Carbon Energy Access

Another priority area is expanding access to low-carbon energy while generating wider social and environmental benefits.

Relevant projects may focus on innovative approaches that:

• Expand access to clean energy.
• Reduce dependence on high-carbon energy sources.
• Improve energy access for underserved communities.
• Support sustainable local development.
• Generate social and economic benefits alongside environmental gains.

Organizations working on community-based low-carbon energy solutions may therefore find this funding area particularly relevant.

4. Chemicals and Waste Management

The program supports initiatives designed to reduce pollution and strengthen environmentally responsible approaches to chemicals and waste management.

Potential areas of intervention include:

• Waste reduction.
• Waste management.
• Pollution prevention.
• Community-based waste solutions.
• Safer management of chemicals.
• Circular approaches to resource use.
• Initiatives protecting human and environmental health.

Projects should demonstrate how the proposed approach can contribute to reduced pollution and improved environmental outcomes.

5. Sustainable Urban Solutions

The fifth strategic priority focuses on innovation that can make cities and urban communities more sustainable and resilient.

Potential initiatives may address:

• Sustainable urban development.
• Urban environmental challenges.
• Climate resilience.
• Sustainable resource management.
• Urban waste.
• Low-carbon urban solutions.
• Community-based approaches to urban sustainability.
• Environmental innovation in cities.

This area is particularly relevant to CSOs developing solutions to environmental problems associated with rapidly growing urban populations.

Who Can Apply?

The program is specifically designed for civil society organizations, rather than individual applicants.

Applicant organizations must satisfy the eligibility requirements established by the program.

Civil Society Organization Requirement

An applicant must be a legally established civil society organization.

The organization must have:

• Legal status; and
• A bank account held in the organization’s name.

This means individuals applying independently are not the primary target of this funding opportunity.

Organizations should ensure that their legal registration and financial arrangements meet the program’s requirements before submitting an application.

Location Requirement

Applicants must be based in a GEF SGP eligible recipient country.

Furthermore, the initiatives being proposed for replication or scaling must also be based in eligible GEF recipient countries.

The program therefore has a defined geographic eligibility framework rather than being open to organizations from every country worldwide.

Eligible Countries and Regions

GEF recipient countries covered by the program are organized into four broad regions:

• Africa — 54 countries
• Latin America and the Caribbean — 33 countries
• Eastern Europe, Caucasus and Central Asia (EECCA) — 18 countries
• Asia-Pacific and Oceania — 39 countries

Applicants should consult the official full country list before beginning an application because eligibility is determined according to the program’s designated GEF recipient-country framework.

What Makes This Opportunity Different?

One of the most important features of the CSO Challenge Program is its focus on organizations with demonstrated achievement and impact.

The program is not simply seeking ideas that sound innovative on paper. It is designed to support organizations that can demonstrate that their approaches have already produced meaningful results and have potential for greater impact.

This makes evidence especially important.

A strong applicant should be able to demonstrate:

1. What environmental problem it is addressing.
2. What solution it has developed or implemented.
3. Where the solution has already been implemented.
4. What results have been achieved.
5. Why the solution is innovative or particularly effective.
6. What evidence demonstrates its success.
7. Why the solution can be replicated, adapted, or scaled.
8. What additional funding is required to achieve expansion.
9. How the proposed project will generate measurable environmental benefits.
10. How communities and relevant stakeholders will participate.

Inclusion Is a Major Program Priority

The CSO Challenge Program strongly encourages projects that meaningfully engage:

• Women.
• Youth.
• Indigenous Peoples.
• Local communities.

This means applicants should consider inclusion not merely as an additional component of a project, but as part of the design and implementation of the proposed environmental solution.

Organizations should demonstrate how relevant groups will participate in decision-making, implementation, knowledge generation, resource management, or other aspects of the initiative.

Projects that integrate environmental impact with meaningful community participation may therefore align particularly well with the program’s objectives.

Program Goals

The CSO Challenge Program has four major goals.

Recognize Innovative Environmental Initiatives

The program seeks to identify and recognize environmental approaches that demonstrate strong potential for impact.

It particularly values initiatives that can be replicated or scaled beyond their original location.

Strengthen Organizational Capacity and Impact

Selected CSOs can receive support aimed at strengthening their ability to design, implement, and scale innovative environmental solutions.

This reflects the program’s broader understanding that scaling an environmental solution requires more than money alone. Organizations may also need stronger systems, technical expertise, partnerships, knowledge, and implementation capacity.

Promote Peer-to-Peer Learning and Partnerships

The program seeks to facilitate knowledge exchange and collaboration among:

• Civil society organizations.
• Governments.
• Donors.
• Private-sector actors.
• Other relevant stakeholders.

Peer learning can allow organizations to learn from environmental solutions implemented in other communities and countries while also sharing their own experiences.

Support Inclusive Environmental Action

The program promotes environmental approaches that meaningfully include women, youth, Indigenous Peoples, and local communities.

This reflects the principle that environmental solutions are more likely to generate sustainable outcomes when the people directly affected by environmental challenges are involved in developing and implementing responses.

Organizations Behind the Program

The initiative is supported by the Global Environment Facility (GEF) and led by the International Union for Conservation of Nature (IUCN), in partnership with RTI International.

Global Environment Facility

The GEF brings together several multilateral funds working to address major global environmental challenges through integrated approaches.

According to the information provided by the program, the GEF has supplied more than US$26 billion in financing and mobilized an additional US$148 billion for country-driven priority projects over more than three decades.

International Union for Conservation of Nature

IUCN is a major international environmental organization with government and NGO members and a global network of volunteer experts.

Its work focuses on finding practical solutions to environmental and development challenges, including biodiversity conservation, ecosystem protection, and sustainable development.

RTI International

RTI International is an independent scientific research institute that works across multiple disciplines, including social sciences, statistics, data, laboratory sciences, engineering, and other technical fields.

Its partnership with the initiative brings additional research and technical expertise to the program.

Why CSOs Should Consider Applying

For an established environmental organization, a grant of up to US$300,000 can provide substantial resources for expanding a proven solution.

The opportunity can be particularly valuable for organizations that have already completed pilot projects and now need funding to move toward larger-scale implementation.

Potential benefits include:

• Significant financial support for environmental initiatives.
• Resources for replication and scaling.
• Opportunities to expand successful approaches into new locations.
• Support for adapting solutions to new contexts.
• Opportunities for organizational strengthening.
• Increased visibility for innovative environmental work.
• Opportunities for peer-to-peer learning.
• Potential partnerships with governments, donors, and private-sector actors.
• Greater environmental and community impact.

How Applicants Can Prepare

Organizations interested in the program should begin by assessing their readiness.

Step 1: Confirm Organizational Eligibility

First, verify that the organization:

• Is a legally recognized CSO.
• Has a bank account in the organization’s name.
• Is based in an eligible GEF recipient country.
• Meets the program’s organizational requirements.

Step 2: Identify the Environmental Solution

Applicants should clearly define the environmental solution they want to replicate, adapt, or scale.

Avoid presenting only a broad environmental problem.

Instead, explain the specific approach the organization has developed and the evidence showing that it works.

Step 3: Document Previous Results

Evidence of previous impact is particularly important for this program.

Organizations should collect relevant information such as:

• Previous project outcomes.
• Environmental indicators.
• Community-level results.
• Number of people or communities reached.
• Conservation achievements.
• Restoration results.
• Changes in resource use.
• Partnerships established.
• Lessons learned.
• Monitoring and evaluation findings.

Step 4: Develop a Clear Scaling Strategy

Applicants should explain what will happen if additional funding is received.

For example, will the project:

• Reach additional communities?
• Expand into another region?
• Replicate an existing model?
• Adapt an approach for a new ecosystem?
• Increase the number of beneficiaries?
• Establish new partnerships?
• Develop a more sustainable implementation model?

The scaling pathway should be realistic and supported by evidence.

Step 5: Integrate Inclusion

Applicants should explain how the project will meaningfully engage women, youth, Indigenous Peoples, and local communities where relevant.

This could include participation in:

• Project design.
• Governance.
• Implementation.
• Monitoring.
• Decision-making.
• Knowledge sharing.
• Livelihood activities.
• Conservation activities.

Step 6: Review the Official Guidelines

Before preparing a final submission, organizations should carefully consult the official Guidelines for Applicants and the complete list of GEF recipient countries.

The guidelines should be treated as the authoritative source for detailed application requirements.

Important Considerations for Applicants

Organizations should avoid assuming that environmental relevance alone guarantees eligibility.

A proposal should demonstrate a strong connection between:

Existing success → proven solution → proposed expansion → measurable impact

Applicants should also ensure that the requested funding is appropriate for the proposed activities and project duration.

Because the program prioritizes replication, adaptation, and scaling, organizations with only an undeveloped concept and no demonstrated record of implementation may not be as well aligned as organizations with proven environmental solutions.
