The grant's core objective is 'Advancing Earth System Models to increase understanding of Earth system change'. It aims to enhance capabilities for predicting Earth system evolution and regional climate variability, including extreme events. It also seeks to strengthen collaboration in Earth system and climate modeling sciences, contributing to the next generation of Earth System Models (ESMs) and advancing the long-term science and evidence base for European and international policies.
Explicit identification of target recipient type and size: The grant is open to any legal entity, but its research focus is best suited for organizations involved in scientific research and development, such as universities, public research organizations, and non-governmental organizations. There are no specific size restrictions.
MUST state if grant is 'SECTOR-SPECIFIC' or 'SECTOR-AGNOSTIC': This grant is SECTOR-SPECIFIC, focusing on environmental science, climate science, and advanced modeling technologies.
Geographic scope and any location requirements: The grant targets organizations established in EU Member States, Horizon Europe Associated Countries, and a list of specific low- and middle-income countries. International cooperation, particularly with the Global South, is encouraged for capacity building.
Key filtering criteria for initial grant screening: Focus on advancing Earth System Models, understanding Earth system change, climate prediction, and strong emphasis on research and innovation actions (RIA).
Grant frequency and program context: This is a specific topic within the 'Horizon Europe Work Programme 2023-2025', under Cluster 5 'Climate, Energy and Mobility', Destination 1 'Climate Sciences and Responses'. While Horizon Europe is recurring, this specific call is for the 2025 Work Programme period.
Financial Structure
Funding amounts: The estimated budget for this topic is 15000000.0 EUR, with 2 expected grants. The minimum and maximum contribution per project is 7500000.0 EUR.
Currency: EUR.
Funding Rate: For 'Research and Innovation Actions' (RIA), the funding rate is 100.0% of eligible costs.
Eligible Costs: Grants take the form of a lump sum contribution, authorized under the Decision of 7 July 2021. The lump sum is an approximation of beneficiaries' underlying actual costs, covering direct and indirect costs.
Direct cost categories typically include: Personnel costs (employees, SME owners, natural persons), Subcontracting costs, Purchase costs (travel, equipment, other goods, works, and services), Financial support to third parties (if allowed by call conditions), Internally invoiced goods and services, Transnational access to research infrastructure costs, Virtual access to research infrastructure costs, and PCP/PPI procurement costs (if applicable).
Indirect costs are calculated at a 25.0% flat rate of the total eligible direct costs (excluding subcontracting, financial support to third parties, and any unit costs or lump sums that already include indirect costs).
Ineligible Costs: Any costs that would be ineligible under standard Horizon Europe rules should not be included in the lump sum estimation.
Payment Schedules: A pre-financing payment is normally provided at the start (typically 160% of average EU funding per reporting period). Interim payments are linked to periodic reports. The final grant amount is calculated after the project's end, based on a final report.
Financial Guarantees: An amount ranging from 5.0% to 8.0% of the maximum grant amount will be deducted from the pre-financing payment and transferred to the mutual insurance mechanism.
Audit Requirements: Checks, reviews, and audits will focus on the technical implementation of the action and the fulfillment of conditions for releasing lump sum contributions per work package, rather than financial ex-post audits. Beneficiaries have no obligation to document costs incurred for the action but remain subject to national accounting rules.

Scoring and Thresholds
Each criterion ('Excellence', 'Impact', 'Quality and efficiency of the implementation') is scored out of 5.
A minimum threshold of 3 applies to each individual criterion.
An overall threshold of 10 applies to the sum of the scores for all three criteria.
To be considered for funding, proposals must pass both the individual criterion thresholds and the overall threshold.
Compliance & Special Requirements
Regulatory Compliance
Projects must comply with all applicable EU, international, and national laws and ethical principles (including research integrity).
Activities must focus exclusively on civil applications.
Specific exclusions apply: human cloning for reproductive purposes; heritable genetic modification of human beings (except for cancer treatment of gonads); creation of human embryos solely for research/stem cell procurement.
Projects must align with EU policy interests and priorities (e.g., environment, social, security, industrial policy).
Data Protection and Privacy
Personal data related to the application will be processed in accordance with Regulation 2018/1725, solely for evaluation, grant management, and program monitoring/evaluation/communication.
Intellectual Property Policies
Intellectual property rights (IPR), background, and results are governed by the grant agreement (Article 16 and Annex 5).
In case of a public emergency, beneficiaries may be required to grant non-exclusive licenses to their results for a limited period on fair and reasonable conditions to entities addressing the emergency.
The granting authority may object to transfers of ownership or exclusive licensing of results for up to four years after the project ends.
Security Requirements
The topic is 'subject to restrictions for the protection of European communication networks'. Therefore, entities assessed as 'high-risk suppliers' of mobile network communication equipment (and any entities they own or control) are not eligible to participate as beneficiaries, affiliated entities, or associated partners.
Project-Specific Scope and Focus
Actions should improve the simulation of the coupled Earth system and its sensitivity to forcings, addressing poorly understood processes, interactions, and feedbacks. This includes areas such as:
The interplay between global change, regional climate variability, and changes in climate and weather extremes.
Terrestrial-ocean-climate interactions.
Coupled climate-carbon-water cycle feedbacks.
Coupled climate-ocean-ice interactions.
Aerosol-cloud-climate forcing and feedback.
Climate-vegetation-fire interactions.
Climate-air quality interactions.
Interactions between land use scenarios and regional climate.
Increased collaboration across different model development approaches (various resolutions and realism) is expected.
Projects should utilize and improve existing and new observational/reanalysis datasets, models, emulators, and analysis tools for bias identification, calibration, validation, and evaluation.
State-of-the-art digital technologies like machine learning, big data analytics, and Artificial Intelligence (AI) should be exploited.
High standards of transparency and openness are required, including assumptions, protocols, code, and data managed in compliance with FAIR principles (Findable, Accessible, Interoperable, Reusable).
Open access to any new modules, models, or tools developed or substantially improved with EU funding is mandatory through documentation, model code, and input data availability.
Cross-Cutting Themes and Collaboration
Projects are strongly encouraged to connect, coordinate, and participate in networking, intercomparison, and joint activities to maximize synergies and complementarities.
Clustering activities with other relevant projects (within and outside Horizon Europe) are expected, particularly with 'HORIZON-CL5-2025-06-D1-01' and 'HORIZON-INFRA-2025-01-SERV-02'.
International cooperation is encouraged, especially with the Global South, to promote capacity and consensus building, for example, by training early career researchers.
