Funding Description
What is funded
The call "HORIZON-CL5-2025-06-D1-01 – Climate simulations data and knowledge for optimal support of IPCC Assessments and International Policy" finances large-scale Research and Innovation Actions (RIA) implemented through a single lump-sum grant.
* Total EU contribution per project: up to EUR 56 million (lump-sum)
* Indicative project duration: 4–6 years (covering the full IPCC AR7 cycle)
* Maximum share for infrastructure improvements (software, tools, HPC adaptation): ≤ 30 % of total eligible costs
* Ring-fenced budget for Global South capacity-building (financial support to third parties): ≤ EUR 1 million, max EUR 60 000 per individual third-party grant
* Mandatory open science obligations: open access to all new/updated models, code, data and documentation (FAIR-compliant)
Eligible applicants
* Consortia of minimum three independent legal entities from three different EU Member States or Horizon Europe Associated Countries (standard HE rule).
* International partners from non-associated third countries can take part, but only organisations automatically eligible for funding (see Programme Guide) receive EU funds; others participate at their own cost unless national funding is secured.
* Beneficiaries must demonstrate the operational capacity to run state-of-the-art Earth System Models (ESMs) on Tier-0/Exascale HPC systems and to manage Petabyte-scale data.
* Participation of policy users (e.g. IPCC WG leads, UNFCCC secretariat, Copernicus, DG CLIMA) and of Global South institutes is highly encouraged and scored under impact.
Cost model and payments
* The EU pays a fixed lump-sum agreed at grant signature; payments are linked to the completion of work packages/milestones, not to real costs.
* Usual Horizon Europe funding rate for RIA: 100 % of the lump-sum for all beneficiaries.
Timetable
* Call opening: 06 May 2025
* Single-stage proposal deadline: 24 Sep 2025, 17:00 CET
* Evaluation results: ~Feb 2026
* GA signature & project start: ~Jun 2026

🇪🇺 Strategic Advantages
EU-wide Advantages & Opportunities for "Climate simulations data and knowledge for optimal support of IPCC Assessments and International Policy"
1. Critical Mass & Distributed Excellence
• Brings together Europe’s >40 Earth-System-Modelling (ESM) groups, Distributed Computing Infrastructures (DCIs) and Integrated Assessment Modelling (IAM) labs, creating a knowledge hub unmatched by any single nation.
• Pooling of complementary expertise in atmospheric physics, biogeochemistry, socio-economic modelling and uncertainty quantification gives proposals a scientific edge and lowers duplication of effort.
2. World-Class Computing Power Through EU Integration
• Direct access to EuroHPC petascale / upcoming exascale systems (LUMI, LEONARDO, JUPITER), impossible or prohibitively expensive for most individual Member States.
• Alignment with EuroHPC, Digital Europe Programme and Destination Earth lowers infrastructure costs (up to 30 % of budget eligible) and speeds up delivery of ultra-high-resolution simulations required for AR7.
3. Harmonised, FAIR, Open Climate Data Space
• The EU’s EOSC and Copernicus Data Space provide pre-existing, federated repositories where project outputs can be Findable, Accessible, Interoperable, Re-usable (FAIR) by default.
• A single European metadata standard enables seamless coupling of ESM, CORDEX and ISIMIP data, boosting cross-disciplinary research and service development.
4. Accelerated Policy Impact Across 27 Member States
• Generates consistent, Paris-aligned climate scenarios for EU Climate Law monitoring, National Energy & Climate Plans (NECPs), Adaptation Strategies and Fit-for-55 legislative packages.
• Enables rapid uptake by the EEA, DG CLIMA, DG ENV and the European Parliament – shortening science-to-policy cycles.
5. Economies of Scale & Lump-Sum Simplification
• HORIZON Lump-Sum model cuts administrative burden and provides cost predictability, freeing researchers’ time for science.
• Joint procurement of data storage, cloud credits and AI accelerators reduces per-partner costs up to 30 %.
6. Synergies With Flagship EU Initiatives
• Copernicus Climate Change Service (C3S): direct ingestion of new scenarios into operational services.
• Destination Earth Digital Twin on Climate Extremes: ready-made showcase use case, boosting project visibility and extending life after grant end.
• Mission Adaptation & Mission Ocean: shared indicators for tipping-point monitoring and coastal risk.
7. Strengthening EU Leadership in IPCC & Global Diplomacy
• Provides coordinated, high-quality European CMIP7 ensemble members, reinforcing EU scientists’ lead-authorship roles and negotiation leverage under UNFCCC.
• Joint trainings and €1 m earmarked for Global South researchers enhance Europe’s science diplomacy and soft power.
8. Market & Innovation Opportunities
• Opens new commercial niches for European SMEs in climate-data analytics, downscaling AI tools and carbon-removal feasibility assessments.
• Harmonised licensing under EU Open-Data Directive lowers entry barriers for start-ups in insurance, infrastructure planning and agri-tech.
9. Social & Geographic Cohesion Benefits
• Involvement of widening-participation countries (e.g., BG, RO, HR) through shared HPC nodes and training bridges the East-West research gap.
• Citizen-science and local authority engagement enabled by pan-EU platforms strengthens societal trust in climate projections.
10. Long-Term Sustainability & Legacy
• Embeds results into permanent EU infrastructures (C3S Climate Data Store, EOSC), guaranteeing data preservation and continuous updating beyond project lifespan.
• Creates a reusable coordination framework (governance templates, APIs, data standards) for future Horizon Europe and FP10 calls.
Bottom Line: Operating at EU scale maximises scientific excellence, cost-efficiency, policy relevance and global influence—delivering a competitive, integrated proposal that single-country consortia cannot match.
