Horizon Europe Cluster 6 2026: What Coordinators Need to Know

Horizon Europe Cluster 6 will launch seven major funding calls in 2026, allocating over EUR 580 million for research and innovation in food systems, biodiversity, natural resources, agriculture, and environment. The draft 2026-2027 Work Programme reveals more than 58 call topics across seven familiar destinations, with calls opening as early as February 2026. Project coordinators should prepare for a mix of single-stage and two-stage evaluation procedures, with typical project budgets ranging from EUR 3-15 million per project.

The cluster supports the European Green Deal objectives, including the Biodiversity Strategy to 2030, Farm to Fork strategy, and the European Climate Pact. According to the European Commission's strategic planning documents, Cluster 6 aims to reduce environmental degradation, halt biodiversity decline, and accelerate the transition to a circular bioeconomy through transformative research and innovation.

What Are the Seven Destination Areas in Cluster 6 2026?

Cluster 6 organizes its funding opportunities across seven strategic destinations that address interconnected challenges in food systems, environmental protection, and sustainable resource management. Each destination targets specific research priorities while promoting cross-cutting collaboration between disciplines and sectors.

Destination 1: Biodiversity and Ecosystem Services focuses on understanding and tackling biodiversity decline, with topics covering insect population dynamics, groundwater ecosystems, deep-sea conservation, and protected area effectiveness. The draft work programme allocates approximately EUR 76 million across both single-stage and two-stage calls.

Destination 2: Fair, Healthy and Environment-Friendly Food Systems addresses sustainable food production, nutrition security, and circular food systems. Research priorities include alternative protein development, food waste reduction, sustainable aquaculture, and climate-resilient agriculture practices.

How Are the 2026 Calls Structured and When Do They Open?

The seven planned calls for 2026 follow a structured timeline with specific opening and deadline dates. Understanding this schedule is crucial for coordination teams planning their proposal strategy and consortium development activities.

According to the draft work programme, calls will open no later than February 12, 2026, following the official work programme adoption expected in late 2025. The European Commission will provide final confirmation of opening dates through the Funding and Tenders Portal.

Single-Stage Calls offer a streamlined evaluation process with one submission deadline. Four single-stage calls are planned for 2026, with deadlines typically falling in April and September. These calls generally target more focused research questions with established methodologies and shorter implementation timelines.

Two-Stage Calls implement a preliminary evaluation in the first stage, followed by full proposal evaluation in the second stage. Three two-stage calls are scheduled for 2026, with first-stage deadlines in April and second-stage submissions due in September. This approach suits complex, high-budget research initiatives requiring detailed consortium coordination.

Many coordinators find that two-stage procedures, despite requiring additional preparation time, allow for more thorough consortium development between stages. The first stage typically requires a shorter proposal (around 70 pages) focusing on excellence and impact, while the second stage demands a complete proposal including detailed implementation plans.

Call-specific eligibility criteria may include minimum consortium requirements, geographic distribution rules, and mandatory participation of specific actor types. The standard Horizon Europe eligibility requires at least two independent legal entities from two different EU Member States or associated countries (HE AGA, Article 44, p.346).

What Types of Actions and Budget Ranges Should Coordinators Expect?

Cluster 6 calls predominantly feature Research and Innovation Actions (RIA), with typical EU contributions ranging from EUR 3 million to EUR 15 million per project. The draft budget distribution indicates significant funding allocation across all seven destinations, with total cluster funding exceeding EUR 580 million for the 2026 calls.

Research and Innovation Actions (RIA) represent the primary funding instrument for Cluster 6 topics. RIA projects focus on technology development, demonstration activities, and innovation pilot implementations. The funding rate covers up to 100% of eligible costs for all participant types, making these actions attractive for both academic and industry partners.

Project duration typically ranges from 36 to 60 months, depending on the specific topic requirements and expected technology readiness level (TRL) advancement. Biodiversity research projects often require longer timeframes for ecological monitoring and data collection, while technology development projects may have shorter, more focused implementation periods.

Multi-actor approaches are mandatory for many Cluster 6 topics, requiring consortia to include research organizations, industry partners, and end-users from the targeted application domains. This requirement ensures that research outputs connect directly to practical implementation needs and market uptake opportunities.

Despite the Commission's emphasis on simplified procedures, consortia often report that budget preparation for multi-actor projects remains complex due to varying cost structures across different partner types. Coordinators should allocate sufficient time for budget harmonization during the proposal preparation phase, particularly when combining academic institutions with SMEs and large industry partners.

The 25% flat rate for indirect costs applies to all Cluster 6 projects (HE AGA, Article 6.2.C, p.126), simplifying cost calculations compared to previous framework programmes. Personnel costs can be declared using actual costs or the optional Horizon Europe personnel unit cost system, which requires prior approval from the granting authority (HE AGA, Article 6.2.A.6, p.71).

How Should Consortia Prepare for the January 2026 Info Days?

The European Commission will organize Cluster 6 Info Days on January 22-23, 2026, providing crucial information about call topics, evaluation criteria, and application procedures. The hybrid event will be hosted in Brussels at the Charlemagne conference facility and streamed online through the Commission's web platform.

Participants will receive detailed presentations on each destination area, including topic-specific requirements, expected impact measures, and evaluation priorities. Commission officials and programme managers will clarify eligibility criteria, budget calculation methods, and proposal submission procedures during dedicated Q&A sessions.

The CARE4BIO project will organize a brokerage event on January 21, 2026, at the Borschette Centre in Brussels. This networking session enables potential applicants to identify partners with complementary expertise across Cluster 6 research domains. The brokerage format includes structured partner search sessions, topic-specific networking rounds, and bilateral meeting opportunities.

Coordinators should prepare for the Info Days by reviewing the draft work programme topics relevant to their research areas and identifying potential collaboration opportunities. Bringing topic-specific questions about evaluation criteria, budget requirements, and consortium composition will maximize the value of the information sessions.

Registration details for both events will be published through the European Commission's research and innovation website. Given the high interest in Cluster 6 topics, early registration is recommended to secure participation in the most relevant sessions.

What Are the Key Changes from Previous Work Programmes?

The 2026-2027 Cluster 6 work programme introduces several refinements while maintaining the core destination structure established in previous programming periods. Notable changes include increased emphasis on digital solutions integration, enhanced requirements for citizen science involvement, and stronger connections to EU Mission objectives.

Digital transformation receives greater prominence across all destinations, reflecting the Commission's commitment to the European Green Deal Digital Transition. Topics increasingly require digital monitoring systems, AI-driven analysis tools, and data platform development as integral project components rather than optional elements.

Citizen science and participatory research approaches become mandatory requirements for specific topic areas, particularly in biodiversity monitoring, environmental observation, and community-driven innovation projects. This shift requires consortia to include partners with demonstrated experience in stakeholder engagement and participatory methodology implementation.

The connection to EU Missions strengthens significantly, with explicit requirements for projects to contribute to Mission objectives and Key Performance Indicators (KPIs). Projects must demonstrate clear pathways to Mission impact through specific deliverables, stakeholder engagement activities, and policy recommendation development.

Open science requirements continue to evolve, with enhanced expectations for FAIR (Findable, Accessible, Interoperable, Reusable) data management and open access publication. Projects must provide detailed data management plans describing research output sharing, validation tools accessibility, and long-term data preservation strategies (HE AGA, Article 44, p.346).

What Practical Steps Should Coordinators Take Now?

With calls opening in early 2026, coordinators should begin immediate preparation activities to ensure competitive proposal submission. The lead time between call opening and deadline submission typically ranges from 6-8 months, requiring structured planning and consortium development.

Start by conducting a thorough analysis of draft topics relevant to your research expertise and institutional capabilities. Cross-reference topic requirements with your organization's track record, available infrastructure, and existing partnerships to identify the most promising opportunities.

Begin consortium building activities now, particularly for two-stage calls requiring extensive collaboration agreements. Many successful Cluster 6 projects report that early partner identification and relationship building significantly improve proposal quality and evaluation scores. Use the January brokerage event to expand your partner network beyond existing collaborations.

Develop detailed budget estimates for target topics, accounting for the 25% indirect cost flat rate and any specific equipment or travel requirements outlined in the topic descriptions. If your organization has not yet applied for the Horizon Europe personnel unit cost, consider whether this simplified approach would benefit your cost management processes.

Prepare preliminary ethics and data management documentation, as these requirements often prove time-consuming during the intensive proposal writing phase. Topics involving environmental sampling, biodiversity research, or community engagement typically require detailed ethics approval processes that can extend beyond standard administrative timelines.

Monitor the official work programme adoption timeline through the European Commission's work programme updates and prepare for immediate action when calls officially open in February 2026.

Coordinators managing multiple proposal submissions should create detailed project timelines accounting for the overlapping deadlines across different calls. The September 2026 deadline concentration requires careful resource allocation to ensure quality submission across multiple opportunities.
