Climate Intervention Environmental Impact Fund

Deadline: 01-Dec-2026

The Climate Intervention Environmental Impact Fund (CIEIF) supports responsible field testing of climate intervention technologies by funding environmental impact assessments, predictive impact modeling, and stakeholder engagement. Each grant provides $75,000, primarily for activities that help researchers assess environmental effects, engage potentially affected communities and agencies, and strengthen the scientific basis for climate intervention research. The programme places strong emphasis on transparency, scientific rigor, scalability, innovation, and publication of results through peer-reviewed venues or externally reviewed reports. The Climate Intervention Environmental Impact Fund (CIEIF) is designed to advance responsible field testing of emerging climate intervention technologies. The fund supports activities that can help researchers better understand and communicate the potential environmental impacts of field tests while engaging stakeholders who may be affected by proposed interventions. CIEIF aims to establish a strong standard for transparency and scientific rigor in the emerging field of climate intervention. The fund focuses on improving the environmental and social assessment of climate intervention field tests.

CIEIF aims to:

The programme is particularly interested in field tests that can provide useful evidence for the responsible development of climate intervention technologies. Applicants must propose a climate intervention field test that prioritizes at least one of the fund’s three main areas:

Stakeholder engagement may involve:

The proposed activities should contribute to understanding and responsibly managing the potential impacts of the field test. Each grant provides $75,000. The funding is primarily intended to support: The grant is designed to support these activities as part of a broader climate intervention field test rather than provide unrestricted funding. The $75,000 grant is disbursed in three installments.

The payment structure is:

Future payments therefore depend on progress against agreed project milestones. Yes. Annual renewal of funding is possible based on the project’s progress and outcomes. Applicants should therefore demonstrate how the proposed work can generate meaningful results and contribute to the responsible development of climate intervention research. CIEIF places significant value on the scalability and innovation of proposed climate intervention field tests.

Applicants should explain:

The fund is intended to support field tests that can produce useful evidence for future research and policy. A major feature of CIEIF is its emphasis on making research results publicly useful and scientifically credible. Applicants are expected to demonstrate a willingness to publish results through: The publication requirement reflects the fund’s broader emphasis on transparency and scientific rigor. Applicants must clearly describe the nature of their entity as part of the application.

Applicants must also:

The application should provide enough information for the programme to understand both the applicant and the proposed field test. Applicants must submit a detailed proposal addressing the requirements established by CIEIF. The proposal should cover areas including: Applicants must address the ten specific questions outlined by CIEIF. Applicants should provide information about previous research relevant to the proposed field test. The proposal should also demonstrate the current level of technical readiness of the intervention. This information helps CIEIF assess whether the proposed field test is sufficiently developed to undertake the planned environmental assessment, modeling, and stakeholder engagement activities. Applicants must explain where the proposed field test will take place and address relevant siting considerations. The application should also provide information about permitting associated with the proposed test. Applicants should identify any regulatory or logistical considerations that could affect implementation. Applicants should identify potential consultants who may contribute to the proposed project. This may be particularly relevant for activities such as environmental impact assessment, predictive modeling, stakeholder engagement, or other specialized components of the field test. The proposal should demonstrate that the applicant has considered the expertise required to conduct the work rigorously. Engagement with potentially impacted stakeholders is one of the central priorities of CIEIF.

Applicants may need to engage with:

Applicants should explain how stakeholder engagement will be incorporated into the project and how the process can contribute to responsible field testing. Applications must be submitted in English. There is no standard application form. Instead, applicants should prepare a detailed proposal that addresses the ten questions specified by CIEIF and provides the requested information about the proposed field test. Applicants should contact the programme manager before submitting an application. The pre-submission discussion is intended to allow applicants to discuss how the proposed project will be delivered and clarify relevant aspects of the submission. Applicants should therefore make contact with the programme manager before formally submitting their proposal. CIEIF has a strict policy regarding artificial intelligence in application materials. The use of AI in application materials is prohibited. Applications containing AI-generated or AI-assisted materials will result in disqualification. Applicants should therefore prepare and submit their application materials without using AI. Applicants should make sure that their proposal directly addresses the environmental and stakeholder considerations associated with the proposed climate intervention field test.

A strong proposal should clearly explain:

Applicants should also address all ten questions specified by CIEIF and discus
