The Climate Intervention Environmental Impact Fund (CIEIF) is accepting applications for its sixth grant round. The programme supports investigators and organisations developing innovative climate-intervention technologies that are close to small-scale field testing.
Importantly, three selected projects will receive $75,000 each. The funding is intended mainly for environmental impact assessment, predictive modelling and stakeholder engagement.
What Programme Is This?
The Climate Intervention Environmental Impact Fund provides grants for assessing the possible effects of innovative climate-intervention technologies before field testing.
Rather than funding general project implementation, the programme focuses on understanding potential environmental, social, economic and health impacts.
Who Is Eligible for the Climate Intervention Environmental Impact Fund 2026?
Qualified investigators and organisations developing innovative climate-intervention technologies can apply.
The fund has global reach and may consider applications from private businesses. However, nonprofit and academic institutions receive higher priority.
Also, international projects may receive greater priority when a US nonprofit partner is available to accept the grant.
Individuals and student projects are not eligible.
What Country or Region Is Eligible for the Climate Intervention Environmental Impact Fund 2026?
The programme has a global geographic scope.
Therefore, applicants can be based outside the United States. However, the fund notes that international projects may receive higher priority when they have an appropriate US nonprofit partner.
Nigeria is not excluded by the information provided in the source article.
What Does the Grant Cover?
Each selected project can receive $75,000.
The funding can support:
- Environmental impact assessment
- Predictive environmental impact modelling
- Stakeholder engagement
- Consultant costs
- Relevant staff time
- Closely related project expenses
The first third of the grant is provided after discussions about expert consulting needs. Further payments are linked to agreed project milestones.
What Are the Academic Requirements for the Climate Intervention Environmental Impact Fund 2026?
The source does not state a specific university degree or academic qualification as a requirement.
Instead, applicants must be qualified investigators or organisations working on an innovative climate-intervention technology that is approaching a small-scale field test.
Academic institutions are specifically identified as a priority group.
What Types of Projects Are Eligible?
Eligible projects should involve innovative climate interventions that could potentially provide meaningful climate benefits.
Examples include:
- Biochar
- Enhanced weathering
- Carbon dioxide removal methods other than DAC
- Cloud brightening
- Ocean interventions
- Marine carbon removal
- Methane removal
- Agricultural climate interventions
- Ice and land albedo enhancement
- Greenhouse-gas-removing coatings
The proposed technology should be approaching a small-scale field test rather than remaining at the basic research stage.
What Projects Are Not Eligible?
The fund does not provide general implementation or basic research funding.
Projects focused mainly on the following areas are outside its scope unless they contain an eligible climate intervention:
- Climate adaptation
- Clean energy
- Climate resilience
- General emissions reduction
- Sustainable development
The fund also excludes certain areas, including stratospheric or higher solar radiation management, CCUS and Direct Air Capture (DAC).
What Documents Are Required for the Climate Intervention Environmental Impact Fund 2026?
There is no standard application form.
Instead, applicants should prepare a grant request of no more than 20 single-spaced pages, using 12-point font and written in English.
The submission should include:
- Contact details and team biosketches
- Description of the proposed field test
- Evidence that the technology is ready for testing
- Expected technical and environmental challenges
- Economic, social, health and safety impacts
- Required permits and approvals
- Relevant previous publications
- At least two independent consulting firms
- Proposed $75,000 budget
- Other funding sources
- Relevant insurance arrangements
- Confirmation that results can be published
Important Application Requirement
Applicants should pay close attention to the fund’s instructions.
According to the source article, CIEIF states that AI-generated content cannot be used in cover letters or applications. It also states that applications identified as using AI-generated information may be rejected.
Therefore, applicants should prepare their submission themselves and follow the fund’s instructions carefully.
When Is the Deadline for the Climate Intervention Environmental Impact Fund 2026?
The application deadline is:
December 1, 2026
Grant decisions are expected to be announced by February 1, 2027.
