The expected outcomes across these topics include:enabling institutions to access and utilize scientifically robust climate projections, improving understanding of temperature overshoot impacts, coordinating the European research community's contribution to major scientific initiatives like the IPCC, better coordinating international programs, and improving the overarching infrastructure supporting these efforts.

Eligible Applicant Types:The eligible applicant types are not explicitly defined in the provided text. However, given the nature of Horizon Europe Research and Innovation Actions (RIA) and Coordination and Support Actions (CSA), eligible applicants typically include universities, research institutes, SMEs, large enterprises, and other organizations capable of conducting research and innovation activities. The COFUND action suggests that public and private entities managing funding programs could also be eligible.

Funding Type:The primary funding mechanism is a grant, specifically a "HORIZON Lump Sum Grant" under the Horizon Europe Programme. There are also COFUND actions, where the EU provides co-funding to existing funding programs.

Consortium Requirement:The text implies that both single applicants and consortia are possible, although consortia are more common for RIAs. The encouragement of clustering activities with other relevant projects suggests that collaborative projects are favored.

Beneficiary Scope (Geographic Eligibility):The geographic eligibility includes EU member states and associated countries as described in Annex B of the Work Programme General Annexes. The opportunity also encourages international cooperation, particularly with the Global South, and mentions that non-EU/non-Associated Countries may have specific provisions for funding.

Target Sector:The program targets the climate, energy, and mobility sectors, with a strong focus on climate science, climate modeling, and the development of climate services. It also touches upon high-performance computing and research infrastructures.

Mentioned Countries:The text mentions the "Global South" as a region for encouraged international cooperation. No specific countries are listed, but the Global South is defined as low- to middle-income countries eligible for Horizon Europe funding, as listed on the EU Funding and Tenders Portal.

Project Stage:The expected maturity of projects ranges from research to development and demonstration. The emphasis on generating climate projections, designing simulations, and updating climate data suggests a focus on advancing existing research and models.

Funding Amount:The funding amounts vary depending on the specific topic within the call:

HORIZON-CL5-2025-06-D1-01:€30,000,000

HORIZON-CL5-2025-06-D1-02:€15,000,000

HORIZON-CL5-2025-06-D1-03:€7,500,000 (contributions of €2,500,000 to €3,000,000)

HORIZON-CL5-2025-06-D1-04:€12,000,000

HORIZON-CL5-2025-06-D1-06:€15,000,000 (contributions of €4,000,000 to €5,000,000)

HORIZON-CL5-2025-06-D1-07:€4,000,000 (contributions of €3,000,000 to €4,000,000)

HORIZON-CL5-2025-06-D2-07:€56,000,000

Application Type:The application type is an open call with a single-stage submission process.

Nature of Support:Beneficiaries will receive money in the form of a lump sum grant. There is also scope for providing financial support to third parties, specifically researchers from Global South countries, up to €60,000 per third party.

Application Stages:The application process consists of a single stage.

Success Rates:The success rates are not explicitly mentioned, but the indicative number of grants for each topic provides some insight into the potential competitiveness.

Co-funding Requirement:For most of the Research and Innovation Actions (RIA) and Coordination and Support Actions (CSA), co-funding is not explicitly mentioned as a requirement. However, the HORIZON-COFUND action implies a co-funding element, as it is designed to supplement existing funding programs.

Summary:This Horizon Europe Cluster 5 call focuses on "Climate simulations data and knowledge for optimal support of IPCC Assessments and International Policy." It seeks to improve the accuracy, reliability, and accessibility of climate projections to inform policy decisions and support international climate efforts, particularly the IPCC. The call includes several topics, ranging from generating global climate projections using state-of-the-art Earth System Models to coordinating climate science communities and improving existing infrastructure. The funding is primarily in the form of lump sum grants, and international cooperation, especially with the Global South, is encouraged. Applicants should be research institutions, universities, or other organizations with expertise in climate modeling, simulation, and data analysis. The call emphasizes transparency, open science practices, and the co-creation of solutions with policymakers to ensure the relevance and impact of the research. The application process is a single-stage submission, with a deadline of September 24, 2025.
