Opportunity Description

The Climate Intervention Environmental Impact Fund (CIEIF) is inviting applications for its sixth grant round, offering three grants of US$75,000 each to support independent environmental impact assessments, predictive impact modelling and stakeholder engagement for innovative climate intervention technologies approaching small-scale field testing.

The funding is available internationally, including to eligible organisations and research institutions in Africa.

The fund aims to ensure that emerging climate intervention technologies are properly assessed before field testing takes place. It supports research into their potential environmental, social, economic and public health impacts, helping organisations identify possible risks, unintended consequences and challenges associated with implementation.

Eligible technologies may include biochar, enhanced rock weathering, methane removal, marine carbon dioxide removal, ocean-based interventions and other innovative climate solutions with significant potential to address global warming.

The fund does not finance technology development or the implementation of field tests. Its primary focus is independent impact assessment, predictive modelling and meaningful consultation with potentially affected stakeholders.

Key Responsibilities / Programme Activities

Successful applicants will use the grant to undertake one or more of the following activities:

• Environmental Impact Assessments (EIA): Evaluate the potential environmental and related impacts of proposed climate intervention field tests.
• Predictive Impact Modelling: Analyse anticipated outcomes, potential risks and unintended consequences before field testing.
• Stakeholder Engagement: Consult local communities, government agencies and other stakeholders who may be affected by proposed interventions.
• Independent Technical Assessment: Engage qualified external consultants to assess environmental, economic, social and public health implications.
• Research and Reporting: Prepare findings for publication in peer-reviewed journals or independently reviewed reports.

Eligibility Requirements

Applications are open to qualified organisations and project teams worldwide developing innovative climate intervention technologies that are approaching small-scale field testing.

Applicants must meet the following requirements:

• Nonprofit institutions and research organisations are prioritised, although private businesses may also apply.
• Demonstrate the scientific basis and potential scalability of the proposed climate intervention technology.
• Present a credible plan for assessing the environmental, social, economic and public health impacts of the proposed field test.
• Identify relevant government permits and regulatory approvals required for the proposed activities.
• Identify at least two independent consulting firms that could support the required impact assessment, modelling or stakeholder engagement.
• Demonstrate willingness to publish the findings in a peer-reviewed journal or an independently reviewed report.
• Provide information about other funding sou
