Mainstreaming and scaling-up evidence-based Nature-Based Solutions towards a nature positive and climate-resilient economy
Overview
The submission process consists of two stages, with the first stage's deadline set for April 16, 2026, and the second stage for September 23, 2026. The call will open for proposals on February 12, 2026.
Eligible applicants include a wide range of organizations such as research institutions, universities, small and medium-sized enterprises (SMEs), large enterprises, public authorities, and non-profit organizations, all of which must belong to the EU member states or associated countries. Collaboration among multiple stakeholders in a consortium is highly encouraged to address the systemic integration of nature-based solutions (NbS) across sectors and policy levels.
The funding is designed to support projects that co-design, develop, and implement large-scale NbS pilots. Proposals should focus on contributing robust evidence, knowledge, and practices to enhance the understanding and effectiveness of NbS, while also addressing challenges related to climate change, biodiversity conservation, and ecosystem resilience. Projects should align with significant EU policies, including the European Green Deal and the EU Biodiversity Strategy for 2030.
The opportunity not only emphasizes the importance of collaboration but also provides financial support to third parties, allowing additional stakeholders to engage in the projects, with up to €60,000 available per third party.
Overall, this call represents a significant investment in advancing research and the practical application of nature-based methods to tackle critical environmental issues. Applicants are encouraged to submit concept outlines by the first deadline and develop comprehensive proposals for the second stage, with funding aimed at fostering innovation in addressing environmental sustainability challenges effectively.
Detail
The expected outcomes of funded projects include: enhanced stakeholder understanding of NbS impacts, systemic integration of NbS into policy domains, scientifically credible evidence and projections for NbS effectiveness, and increased practitioner capacity to design and implement adaptive NbS management strategies.
The scope of the proposals should focus on equipping policymakers and practitioners with robust evidence, knowledge, and practices related to NbS. Proposals should contribute to the evidence base supporting the role of NbS in creating a nature-positive and climate-resilient society, aligning with strategies for climate adaptation and mitigation, ensuring economic security, respecting planetary boundaries, and addressing climate uncertainties. A multi-actor approach is encouraged, involving researchers, policymakers, practitioners, and experts from SSH disciplines to enhance the societal impact of research activities.
Proposals should also enable the scaling up and mainstreaming of NbS, aligning with key policies such as the European Green Deal, the EU Biodiversity Strategy for 2030, the Climate Adaptation Strategy, the EU Climate Adaptation Plan, the EU Forest Strategy, the Preparedness Union Strategy, the Kunming-Montreal Global Biodiversity Framework (GBF), the EU water and marine acquis, the European Water Resilience Strategy, and the European Ocean Pact.
Specific actions that proposals should undertake include: co-designing and implementing large-scale NbS pilots, advancing methods for assessing the long-term viability of NbS, facilitating collaboration and knowledge transfer among stakeholders, developing tools to mitigate potential unintended consequences of NbS, and assessing the environmental, social, and economic impacts of NbS. Proposals should also address knowledge gaps identified by IPBES assessments and create synergies with other EU-funded NbS projects, including collaboration with EU NbS Task Forces. Financial support to third parties (FSTP) is permitted, with a maximum of EUR 60,000 granted to each third party.

This Horizon Europe call is essentially a funding opportunity for research and innovation projects that focus on using nature to solve environmental and societal problems. It's about finding ways to protect, restore, and manage ecosystems in a sustainable way to address challenges like climate change, biodiversity loss, and water scarcity. The EU wants to see projects that not only come up with these nature-based solutions but also provide solid evidence that they work, are cost-effective, and can be scaled up to make a real difference. The goal is to encourage policymakers and practitioners to integrate these solutions into their plans and strategies, creating a more resilient and sustainable future. If you're a researcher, policymaker, or practitioner with innovative ideas on how to use nature to tackle these challenges, this call is an opportunity to get funding and support for your project.
