Researchers, nonprofit organisations and companies developing innovative climate interventions can apply for up to USD 75,000 through the sixth grant round of the Climate Intervention Environmental Impact Fund (CIEIF). The funding is designed to support the environmental and social analysis required before or alongside small-scale field testing of innovative climate technologies. CIEIF is particularly interested in projects that are approaching field testing and have the potential to scale toward meaningful global climate benefits. For the sixth grant round, applications are due by 1 December 2026. Grant decisions are expected to be announced by 1 February 2027. What Does the CIEIF Grant Support? The CIEIF grant is specifically intended to help applicants address environmental, social and stakeholder-related issues associated with proposed climate intervention field tests. Applicants must demonstrate how the USD 75,000 would be used primarily for at least one of three areas: Environmental Impact Assessment (EIA). Predictive impact modelling. Engagement with potentially affected stakeholders, including local communities and government agencies. Applications that do not focus on at least one of these areas may be rejected. The fund recognises that emerging climate interventions can present complex environmental, economic, social, public health, safety and governance questions. Its grants are therefore intended to help project teams understand and address potential impacts before or during field testing. What Types of Projects Are Eligible? CIEIF is looking for innovative climate intervention technologies that are sufficiently developed to be considered for small-scale field testing. Applicants need to demonstrate that previous research supports the readiness of their technology for the proposed field test. They must also explain what makes the intervention innovative and how it could potentially be scaled to a globally relevant level. The proposed field test should therefore go beyond a general climate or sustainability project. CIEIF is interested in technologies that could potentially generate significant climate benefits if successfully developed and scaled. Projects should also address anticipated technical and environmental challenges, including potential: Economic impacts. Social impacts. Public health concerns. Safety risks. Environmental impacts. Siting challenges. Regulatory and permitting requirements. Stakeholder and social-license considerations. Who Can Apply? The funding opportunity is open to eligible organisations and research teams working on qualifying climate intervention field tests. Potential applicants include: Nonprofit organisations, including academic institutions. Qualified research teams operating through eligible organisations. Private businesses developing eligible climate-intervention field tests. Individuals and student projects are not eligible to apply independently. International projects may also be considered. According to the supplied funding information, projects outside the United States may receive higher priority where a US nonprofit partner can accept the grant. Applicants should confirm their organisational eligibility and any requirements concerning international partnerships directly with CIEIF before submitting an application. What Must the Application Demonstrate? CIEIF does not provide a standard application form or template. Instead, applicants must prepare a grant request addressing a series of questions. The application should provide complete contact information and biosketches for all personnel involved in the proposed field test, explain the nature of the applicant organisation and provide its website. Applicants must provide a detailed description of the proposed field test, including previous research demonstrating that the technology is ready for testing. The application should also discuss the proposed location and anticipated technical and environmental challenges. An important part of the proposal is explaining how the intervention could potentially scale to a globally relevant level. Applicants must also identify required government permits and approvals and provide previous publications related to the feasibility and scalability of the intervention. The proposal should identify at least two independent consulting firms that could potentially assist with impact analysis, impact modelling or other relevant economic, social-license or health considerations. How Can the USD 75,000 Be Used? Applicants must provide a rough budget explaining how the grant would primarily support EIA, predictive impact modelling and/or stakeholder engagement. The proposed budget may include salary time for the applicant and consultant fees associated with the environmental and related analysis. Closely associated project expenses may also be included where appropriate. Applicants must also disclose other sources of funding supporting the investigation and describe any insurance that may cover the proposed field test. The application should additionally confirm the applicant’s willingness to publish the results of the field test at an appropriate time. Projects Must Be Willing to Publish Results Publication is an important part of the CIEIF selection process. Successful grantees must be willing to publish their field-test results either through a peer-reviewed academic journal or as a report receiving independent external peer review. CIEIF may allow flexibility regarding publication timing where publication could affect permitting, social licence, implementation funding or other practical considerations. The fund intends to use supported publications and reports as examples that can inform future climate intervention field tests. What Projects Are Not Funded? The CIEIF opportunity is narrowly focused on environmental and social analysis associated with innovative climate interventions. It does not generally fund projects focused on conventional climate adaptation, climate resilience, clean energy or sustainable development. The supplied eligibility information also specifically excludes: Direct Air Capture (DAC). Carbon Capture, Utilisation and Storage (CCUS). Stratospheric Solar Radiation Management (SRM). Applicants should therefore ensure that their proposed technology falls within CIEIF’s specific climate-intervention focus before investing significant time in preparing an application. How the Grant Is Disbursed Selected applicants will first engage in discussions with CIEIF personnel about the expert consulting needs associated with their proposed field test. These discussions can cover technical, siting, legal and permitting issues, as well as EIA, impact modelling and engagement with potentially affected stakeholders. After the initial scoping discussions are completed, the grantee receives the first third of the USD 75,000 grant upfront. The remaining two payments are made according to a schedule negotiated around project benchmarks. CIEIF also states that repeated annual funding may be possible, although applicants should not assume that future funding is guaranteed. There will be no direct contractual relationship between CIEIF and outside consultants. CIEIF staff may also provide occasional advice and consultation during the grant. Successful grantees must agree to be identified on the CIEIF website and acknowledge CIEIF on their own websites. Application Deadline Deadline: 1 December 2026 Grant decisions for the sixth round are expected to be announced by: 1 February 2027 CIEIF encourages applicants to contact its manager before submitting their application to discuss the appropriate method of delivery. How to Apply There is no standard application form or template. Applicants should prepare a concise grant request addressing CIEIF’s required questions. The main application should not exceed 20 single-spaced pages using 12-point font and must be written in English. Biosketches and essential scientific publications may be supplied as supplementary material, with CIEIF encouraging applicants to link to supplementary materials whenever possible. Once the application is ready, applicants should contact Peter T. Jenkins, Manager, CIEIF, at: info@CIEIF.org CIEIF states that applications will be kept confidential. Official CIEIF website: https://cieif.org/ Official grant guidelines: https://cieif.org/guidelines-for-grant-applicants/ Important AI Application Warning Applicants should pay particular attention to CIEIF’s explicit policy on artificial intelligence. The fund states that AI use in cover letters and applications is not acceptable and that applications will be reviewed for AI use. According to the fund, applications detected as using AI will be rejected immediately and the applicant may be barred from future applications. Applicants should therefore prepare their application materials in their own voice and based on their own research, experience and project information. Final Takeaway The CIEIF sixth grant round provides up to USD 75,000 for environmental impact assessment, predictive impact modelling and stakeholder engagement connected to innovative climate intervention field tests. With three grants available and applications accepted worldwide, the opportunity could be particularly relevant to eligible research institutions, nonprofits and companies developing emerging climate interventions that are approaching small-scale field testing. However, applicants should carefully assess the fund’s exclusions and ensure their project is genuinely focused on an eligible innovative climate intervention rather than general climate adaptation, resilience or clean-energy activities.
