CIEIF Climate Intervention Grants 2026: US$75,000 for Environmental Impact Assessment and Climate Innovation
CIEIF Climate Intervention Grants 2026: US$75,000 for Environmental Impact Assessment and Climate Innovation. The Climate Intervention Environmental Impact Fund (CIEIF) has opened its sixth grant round, offering three grants of US$75,000 each to qualified teams worldwide developing innovative climate-intervention technologies that are approaching small-scale field testing. The funding is specifically designed to support environmental impact assessment, predictive impact modelling and engagement with potentially affected communities, regulators and other stakeholders.
Applications close on:
📅 1 DECEMBER 2026
and grant decisions are expected by:
📅 1 FEBRUARY 2027.
⚠️ Important Accuracy Note
This is not a general climate-action, clean-energy or environmental grant.
CIEIF does not fund ordinary projects in:
- Climate adaptation
- Renewable energy
- Climate resilience
- General emissions reduction
- Sustainable development
- Basic research
- Technology development
- Field-test implementation
Instead, the fund supports the environmental and social due diligence surrounding an innovative climate-intervention technology that is already:
CLOSE TO FIELD TESTING.
The grant must focus primarily on at least one of these three areas:
🌱 ENVIRONMENTAL IMPACT ASSESSMENT
📊 PREDICTIVE IMPACT MODELLING
or:
🤝 STAKEHOLDER ENGAGEMENT.

🌍 What Is the Climate Intervention Environmental Impact Fund?
CIEIF Climate Intervention Grants 2026: US$75,000 for Environmental Impact Assessment and Climate Innovation
The Climate Intervention Environmental Impact Fund supports scientists, innovators, researchers and organisations that are preparing to test climate-intervention technologies with the potential to address:
ROOT CAUSES OF GLOBAL WARMING
or:
MAJOR GLOBAL EFFECTS OF CLIMATE CHANGE.
Its role is not to finance the full climate technology.
Instead, CIEIF concentrates on the important work required before or around a field test, including understanding:
ENVIRONMENTAL RISKS
SOCIAL IMPACTS
ECONOMIC EFFECTS
PUBLIC-HEALTH CONCERNS
REGULATORY REQUIREMENTS
and:
COMMUNITY ACCEPTANCE.
💰 How Much Funding Is Available?
CIEIF is offering:
THREE GRANTS
worth:
💵 US$75,000 EACH.
Applicants should explain clearly how the full US$75,000 would be used primarily for:
ENVIRONMENTAL IMPACT ASSESSMENT
PREDICTIVE MODELLING
and/or:
STAKEHOLDER ENGAGEMENT.
💳 How Is the Funding Paid?
Selected applicants receive the first:
ONE-THIRD OF THE US$75,000
after project scoping discussions with CIEIF.
The second and third payments are then released according to:
NEGOTIATED PROJECT BENCHMARKS.
CIEIF also states that:
REPEATED ANNUAL FUNDING MAY BE POSSIBLE.
🌱 What Activities Can Be Funded?
The grant can support work in three core areas.
1️⃣ Environmental Impact Assessment
Projects may use funding to investigate potential impacts of a proposed climate-intervention field test on areas such as:
ECOSYSTEMS
WATER
SOILS
AIR QUALITY
BIODIVERSITY
and:
LOCAL ENVIRONMENTS.
CIEIF may also consider wider impacts involving:
ECONOMIC
SOCIAL
and:
PUBLIC-HEALTH
risks.
2️⃣ Predictive Impact Modelling
Projects can use funding for:
PREDICTIVE MODELLING
to understand the likely environmental or social effects of an intervention before or during field testing.
This can help researchers identify:
POTENTIAL RISKS
UNINTENDED CONSEQUENCES
and:
MITIGATION NEEDS.
3️⃣ Stakeholder Engagement
The grant can also fund engagement with people or institutions potentially affected by the proposed intervention.
This can include:
LOCAL COMMUNITIES
GOVERNMENT AGENCIES
REGULATORS
INDIGENOUS OR COMMUNITY STAKEHOLDERS
and other relevant parties.
🌦️ What Climate Technologies Can Be Eligible?
CIEIF Climate Intervention Grants 2026: US$75,000 for Environmental Impact Assessment and Climate Innovation
CIEIF considers innovative technologies with potential to scale to meaningful climate benefits.
Examples identified by the fund include:
🌱 BIOCHAR
🪨 ENHANCED WEATHERING
🌊 MARINE CARBON-DIOXIDE REMOVAL
🐄 LIVESTOCK METHANE CAPTURE
🌫️ ATMOSPHERIC METHANE REMOVAL
☁️ CLOUD BRIGHTENING
❄️ ICE & LAND ALBEDO ENHANCEMENT
🌊 OCEAN FERTILISATION
🏭 GREENHOUSE-GAS REMOVAL COATINGS
and other comparable climate interventions.
🚫 Which Technologies Are Excluded?
CIEIF specifically excludes:
STRATOSPHERIC OR HIGHER SOLAR RADIATION MANAGEMENT
including approaches such as stratospheric aerosol interventions.
It also excludes:
DIRECT AIR CAPTURE — DAC
and:
CARBON CAPTURE, UTILISATION & STORAGE — CCUS
because those fields already have other major funding mechanisms.
⚠️ This Is Not Funding for the Technology Itself
CIEIF makes a clear distinction between:
ASSESSING A CLIMATE INTERVENTION
and:
PAYING TO BUILD OR DEPLOY IT.
The fund does:
NOT SUPPORT BASIC RESEARCH
and does:
NOT PAY FOR FIELD-TEST IMPLEMENTATION.
Applicants therefore need to demonstrate that their proposed technology has already advanced far enough to justify:
REAL-WORLD FIELD TESTING.
🎯 Who Can Apply?
CIEIF considers applications from:
QUALIFIED INVESTIGATORS
and:
PROJECT TEAMS
working through eligible organisations.
The fund gives highest priority, other factors being equal, to:
NONPROFIT INSTITUTIONS
including:
ACADEMIC INSTITUTIONS.
🏢 Can Private Companies Apply?
Yes.
CIEIF states that applications from:
PRIVATE BUSINESS PROJECTS
preparing climate-intervention field tests may also be considered.
🚫 Can Individuals Apply?
No.
CIEIF explicitly states:
INDIVIDUALS ARE NOT FUNDED.
🎓 Can Student Projects Apply?
No.
The programme also specifically excludes:
STUDENT PROJECTS.
🌍 Is the Grant Open Worldwide?
Yes.
CIEIF states that:
THE REACH OF POTENTIAL GRANTS IS GLOBAL.
CIEIF Climate Intervention Grants 2026: US$75,000 for Environmental Impact Assessment and Climate Innovation
This means suitable projects can come from:
AFRICA
ASIA
EUROPE
THE AMERICAS
OCEANIA
and other regions.
🌍 International Projects
International projects are eligible.
However, CIEIF says that international projects may receive higher priority where a:
U.S. NONPROFIT PARTNER
is available to accept the grant as a donation.
This is an important consideration for organisations outside the United States.
🇿🇼 Can Zimbabwean Organisations Apply?
Potentially, yes.
Because CIEIF describes its grants as:
GLOBAL
an eligible organisation or qualified project team from Zimbabwe could potentially apply if the proposed climate technology meets the fund’s technical and field-testing requirements.
A Zimbabwean project would need to demonstrate that:
✅ The technology is genuinely innovative
✅ It is near field-test readiness
✅ It could scale to meaningful climate benefits
✅ The grant will fund impact assessment, modelling or stakeholder engagement
and:
✅ The applicant is an eligible organisation rather than an individual or student project.
🌍 Example of an Africa-Based Project
CIEIF’s 2026 grantees include Carbizon, a University of Antwerp-linked project conducting a field test in:
🇰🇪 MURANG’A COUNTY, KENYA.
The project is testing high-intensity:
ENHANCED ROCK WEATHERING
using basalt, biochar and organic matter.
CIEIF funding supports:
ENVIRONMENTAL IMPACT ASSESSMENT
IMPACT MODELLING
and:
LIFE-CYCLE ASSESSMENT.
This demonstrates that African field-test locations can qualify.
