short description
The EU’s Offshore Strategy underlines that the deployment of offshore wind should be based on maritime spatial planning, assessing the economic, social, and environmental sustainability of the installations in a life-cycle perspective, while ensuring co-existence with other activities such as commercial and recreational uses of the sea and fishing. At the same time, it calls for research on the cumulative impacts of offshore energy generation on the environment, which was also underlined in the Communication on Delivering on the EU offshore renewable energy ambitions (2023).
Call objectives
Proposals are expected to address at least five of the following aspects:
- Provide better knowledge and understanding of the cumulative environmental impacts of the offshore wind energy deployment according to the EU targets, when added to the current and planned human activities carried out in the same areas;
- Expand existing studies, field monitoring, and analysis from local to larger areas, and from site- or species-specific impacts to more general ones. Further develop and deploy field monitoring activities, measuring multiple pressures and impacts on marine and coastal ecosystems and their services, as well as pollution, from installation to decommissioning and possible repowering, including operational phase and maintenance activities;
- Test and demonstrate field monitoring and modelling technologies that allow to go beyond state-of-knowledge, regarding life-cycle environmental impacts of offshore wind energy deployments;
- Improve instruments and models for Maritime Spatial Planning, and environmental assessments at plan and project level that are in alignment with public authorities’ needs;
- Improve modelling capacity and environmental impact assessments of future offshore wind deployment;
- Support the identification of areas where wind energy deployment is particularly suitable without significant environmental impact and areas where on the contrary, it should be avoided;
- Identify strategies, test, and demonstrate technologies that avoid, minimise, mitigate and compensate the environmental impact of bottom-fixed and floating offshore wind energy systems, propose mitigation and restoration measures and if feasible, provide net-positive environmental impacts. The activities carried out under this point are expected to achieve TRL 5 by the end of the project.
Particular attention must be dedicated to ensuring that the data produced in the context of this topic is FAIR (Findable, Accessible, Interoperable and Re-usable) and to leveraging existing community practices for data sharing especially those in the relevant European common data spaces and in the European Research infrastructures.
Complementarities with other ongoing and upcoming Horizon Europe projects are expected to be ensured as well as with the European Digital Twin of Ocean (European DTO) and its core infrastructure, for instance the projects funded under topics:
- HORIZON-CL6-2025-02-CLIMATE-02: The ocean-climate-biodiversity-people nexus: uncovering safe operating space for safeguarding the integrity and health of the global ocean;
- HORIZON-MISS-2025-03-OCEAN-08: EU Digital Twin Ocean: Contribution to the EU DTO core infrastructure through applications for sustainable ocean management;
- HORIZON-MISS-2023-OCEAN-01-06: Innovative nature-inclusive concepts to reconcile offshore renewables with ocean protection;
- HORIZON-MISS-2023-OCEAN-01-08: Integration of socio-ecological models into the Digital Twin Ocean;
- HORIZON-CL5-2024-D3-02-08 Minimisation of environmental, and optimisation of socio-economic impacts in the deployment, operation and decommissioning of offshore wind farms.
In addition to considering the most evident environmental impacts of offshore wind energy systems (displacement, collision risk, exposure to aerial and underwater noise, habitat loss and degradation, pollution, etc.), funded projects must include an analysis of possible new impacts, that may become particularly relevant when a high number of wind energy systems is deployed, for instance in relation to the decommissioning and removal of end-of-life offshore wind energy systems, the presence of dynamic cables suspended in the water column, the impact of submarine geohazards on the dynamic cables or the production of microplastics.
Environmental monitoring data must be open source and be shared with the European Marine Observation and Data Network (EMODnet) and the International Energy Agency Wind Energy Systems Technology Collaboration Programme’s (IEA Wind TCP) Task on the environmental effects of wind energy.

Expected results
Our knowledge on such impacts, positive and negative, is more advanced now than when the Offshore Strategy was adopted. However, there are still significant data and knowledge gaps. Most fieldwork studies have been carried out at very localised sites and often focused on specific species. These ad-hoc studies lead to conclusions that can hardly be generalised. A sound monitoring, measuring multiple pressures and impacts on ecosystems and their services, at wider scale and in interaction with other sea activities, is still largely missing. There is also a need to further develop models and other instruments for environmental risk assessment, identification of mitigation measures and recommendations for restoration measures, considering impacts during construction, operation and maintenance, repowering and decommissioning.
Improving instruments, data, and knowledge on the cumulative environmental impacts of offshore energy, as well as a sound monitoring, is key to ensure that its expected fast and large-scale deployment will be sustainable. It will also better equip the EU to contribute to mitigate such impacts and promote sustainable deployment of offshore wind at regional (e.g., through OSPAR in the Northeast Atlantic) or subregional (e.g., through the Greater North Sea basin Initiative) level.
Project results are expected to contribute to all of the following expected outcomes:
- The scientific community, public authorities, project designers, permitting authorities, civil society organisations and citizens have better tools (including Maritime Spatial Planning tools), reliable data and knowledge to monitor, assess and minimise the cumulative environmental, including on biodiversity, and socio-ecological impacts of large-scale bottom-fixed and floating offshore wind energy generation, including at sea-basin level and when combined with other planned or existing human activities;
- The monitoring of cumulative environmental impacts, including on biodiversity, of offshore wind installations is improved, with better tools and open data, in a coherent scheme with pre-existing monitoring programs of the marine environment at large scale;
- Ambitious national and regional offshore wind deployment targets are achieved with positive or minimum negative impacts on the marine and coastal environment;
- Deploy offshore wind energy with minimal impact on marine and coastal ecosystems, and, if possible, with net-positive ones.

Project Partnership
To be eligible for funding, applicants must be established in one of the following countries:
- the Member States of the European Union, including their outermost regions
- the Overseas Countries and Territories (OCTs) linked to the Member States
- countries associated to Horizon Europe - see list of particpating countries
Only legal entities forming a consortium are eligible to participate in actions provided that the consortium includes, as beneficiaries, three legal entities independent from each other and each established in a different country as follows:
- at least one independent legal entity established in a Member State; and
- at least two other independent legal entities, each established in different Member States or Associated Countries.
Any legal entity, regardless of its place of establishment, including legal entities from non-associated third countries or international organisations (including international European research organisations) is eligible to participate (whether it is eligible for funding or not), provided that the conditions laid down in the Horizon Europe Regulation have been met, along with any other conditions laid down in the specific call topic.
A ‘legal entity’ means any natural or legal person created and recognised as such under national law, EU law or international law, which has legal personality and which may, acting in its own name, exercise rights and be subject to obligations, or an entity without legal personality.
other eligibility criteria
Specific cases:
- Affiliated entities (i.e. entities with a legal or capital link to a beneficiary which participate in the action with similar rights and obligations to the beneficiaries, but which do not sign the grant agreement and therefore do not become beneficiaries themselves) are allowed, if they are eligible for participation and funding.
- Associated partners (i.e. entities which participate in the action without signing the grant agreement, and without the right to charge costs or claim contributions) are allowed, subject to any conditions regarding associated partners set out in the specific call conditions.
- Entities which do not have legal personality under their national law may exceptionally participate, provided that their representatives have the capacity to undertake legal obligations on their behalf, and offer guarantees to protect the EU’s financial interests equivalent to those offered by legal persons.
- Legal entities created under EU law (EU bodies) including decentralised agencies may be part of the consortium, unless provided for otherwise in their basic act.
- International European research organisations are eligible to receive funding. International organisations with headquarters in a Member State or Associated Country are eligible to receive funding for ‘Training and mobility’ actions or when provided for in the specific call/topic conditions. Other international organisations are not eligible to receive funding, unless provided for in the specific call/topic conditions, or if their participation is considered essential for implementing the action by the granting authority.
- Joint Research Centre (JRC)— Where provided for in the specific call conditions, applicants may include in their proposals the possible contribution of the JRC but the JRC will not participate in the preparation and submission of the proposal. Applicants will indicate the contribution that the JRC could bring to the project based on the scope of the topic text. After the evaluation process, the JRC and the consortium selected for funding may come to an agreement on the specific terms of the participation of the JRC. If an agreement is found, the JRC may accede to the grant agreement as beneficiary requesting zero funding or participate as an associated partner, and would accede to the consortium as a member.
- Associations and interest groupings — Entities composed of members (e.g. European research infrastructure consortia (ERICs)) may participate as ‘sole beneficiaries’ or ‘beneficiaries without legal personality’. However, if the action is in practice implemented by the individual members, those members should also participate (either as beneficiaries or as affiliated entities, otherwise their costs will NOT be eligible.
- EU restrictive measures — Entities subject to EU restrictive measures under Article 29 of the Treaty on the European Union (TEU) and Article 215 of the Treaty on the Functioning of the EU (TFEU) as well as Article 75 TFEU, are not eligible to participate in any capacity, including as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any).
- Legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine — Given the illegal invasion of Ukraine by Russia and the involvement of Belarus, there is currently no appropriate context allowing the implementation of the actions foreseen in this programme with legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine. Therefore, even where such entities are not subject to EU restrictive measures, such legal entities are not eligible to participate in any capacity. This includes participation as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any). Exceptions may be granted on a case-by-case basis for justified reasons.
With specific regard to measures addressed to Russia, following the adoption of the Council Regulation (EU) 2024/1745 of 24 June 2024 (amending Council Regulation (EU) No 833/2014 of 31 July 2014) concerning restrictive measures in view of Russia’s actions destabilising the situation in Ukraine, legal entities established outside Russia but whose proprietary rights are directly or indirectly owned for more than 50% by a legal person, entity or body established in Russia are also not eligible to participate in any capacity. - Measures for the protection of the Union budget against breaches of the principles of the rule of law in Hungary — Following the Council Implementing Decision (EU) 2022/2506, as of 16 December 2022, no legal commitments can be entered into with Hungarian public interest trusts established under the Hungarian Act IX of 2021 or any entity they maintain. Affected entities may continue to apply to calls for proposals and can participate without receiving EU funding, as associated partners, if allowed by the call conditions. However, as long as the Council measures are not lifted, such entities are not eligible to participate in any funded role (beneficiaries, affiliated entities, subcontractors, recipients of financial support to third parties, etc.).In case of multi-beneficiary grant calls, applicants will be invited to remove or replace that entity in any funded role and/or to change its status into associated partner. Tasks and budget may be redistributed accordingly.
