Call content
short description
With continuous increase in electrification of the car fleet and railways, the share of non-exhaust particulate emissions into the environment becomes increasingly important.
Call objectives
Non-exhaust emissions (NEE) of particles apply to all forms of ground transport and can be categorised as those coming from several sources, such as brake wear, tyre wear, pantograph-catenary wear, wheel-rail contact, road surface wear, as well as vehicle-induced resuspension of road/track dust deposited on the surface. There may be other sources, e.g. engine belts and clutch plates. Quantitative data on the magnitude of non-exhaust emissions are fragmented and highly uncertain, particularly when compared to data for exhaust emissions. Emissions vary widely according to brake, tyre and road surface material, and with driving style. Further research efforts are necessary to increase the understanding of these particles, their creation, ageing and dispersion in the environment.
Moreover, the health impact of NEEs is far less studied, and it remains unclear whether these predominately solid/non-soluble PM may induce the same effects as combustion PM. Additionally, these pollutants has been reported to adversely affect terrestrial systems and aquatic environment as well as the biodiversity; however, it is not clear to what extent.
Research into rail particulate emissions is an equally important area due to its implications for air quality, human health, and environmental impact. However, research data on the health impacts of specific particulate components is limited. Furthermore, comprehensive studies on the chemical composition of rail particulates are scarce. The impact of rail particulates on soil, water, and ecosystems and their biodiversity is not well understood, while more data is needed on how particulates disperse and deposit in different environments, especially in urban versus rural areas. Addressing these research gaps would provide a more comprehensive understanding of rail particulate emissions and contribute to the development of effective mitigation strategies.
In order to address the two aforementioned areas (road and rail), R&I actions are expected to address the following aspects:
- Methods and tools for the segregation of NEE particle sources: i) during particle collection (e.g., due to high background concentrations), ii) attribution of collected material to different sources. Appropriate real-world test conditions, equipment and sampling methods for the evaluation of particles (e.g., separation of total and solid particles)
- Source identification and characterization including detailed source apportionment (brake wear, tyre wear, wheel-rail interaction, resuspension, etc.) and chemical composition;
- Assessment of the influencing parameters: use cases (e.g. different vehicle types or tyre types), conditions (e.g. urban, rural, motorways, tunnels), driving behaviour, state of the road surface or rail tracks; attribution and distribution;
- Emission Measurement Techniques including but not limited to standardized measurement methods and real-time monitoring;
- Downstream assessment: analysis of the deposited material in the environment, assessment of its decomposition, aggregation, dispersion and degradation;
- Health Impact estimates building on existing toxicology studies (or developing new ones if deemed necessary) and long-term exposure effects supported by gender disaggregated data collection and intersectional analysis;
- Estimates on the environmental impact on soil, water, and ecosystems and their biodiversity as well as deposition patterns (i.e. how particulates disperse and deposit in different environments, especially in urban versus rural areas.)
- Mitigations through focusing on State-of-the-Art systems: test systems (including the vehicle e.g., vehicle-lightweight technologies) that can mitigate non-exhaust emissions to reach TRL 6 or higher, innovative tyre and brake designs and materials that balance durability, safety, and reduced abrasion, innovative road surfaces and texture (considering the interaction between tyre and road), runoff and drainage systems. For the railway sector mitigation solutions could include test systems addressing emissions from key mechanical interfaces (e.g., braking and wheel–rail contact), vehicle innovations to reduce wear-related emissions, and infrastructure measures such as optimized track materials, surface treatments, and improved drainage and containment systems. Consider life cycle assessment for the analysis of the systems
- Support standardization and regulation based on the recommendations in support of industrial competitiveness
Proposals should take into consideration the results of previous or on-going EU funded projects such as Leon-T, ULTRAHAS, nPETS and LIFE23-ENV-ES-LIFE NEEVE and any other similar projects.

Expected results
Project results are expected to contribute to all of the following expected outcomes:
- Methods and tools to support measurement, simulation and validation of non-exhaust pollutant emissions in road and railway transport into the environment;
- Estimates on the impact of these pollutants on human health, terrestrial ecosystems and the aquatic environment (including biodiversity in these ecosystems) with particular focus on microplastics and other heavier non-airborne particles;
- Delivery of better emission factors for emission inventories and projections, including the European Monitoring and Evaluation Programme (EMEP), also for resuspension, for which little knowledge exists today;
- Recommendations and mitigation strategies including the determination of appropriate KPIs and assessing the effectiveness of control measures with an appropriate cost-benefit analysis to understand the economic and practical feasibility of different emission reduction strategies.

Legal entities which are established in countries not listed above will be eligible for funding if provided for in the specific call/topic conditions, or if their participation is considered essential for implementing the action by the granting authority.
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.
Unless otherwise provided for in the specific call/topic conditions, 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.
As affiliated entities do not sign the grant agreement, they do not count towards the minimum eligibility criteria for consortium composition (if any).
If projects use satellite-based earth observation, positioning, navigation and/or related timing data and services, beneficiaries must make use of Copernicus and/or Galileo/EGNOS (other data and services may additionally be used).
other eligibility criteria
Specific cases
Affiliated entities — 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 — 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 specific call/topic conditions.
Entities without legal personality — 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.
EU bodies — Legal entities created under EU law including decentralised agencies may be part of the consortium, unless provided for otherwise in their basic act.
Joint Research Centre (‘JRC’) — Where provided for in the specific call/topic 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 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 the 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.
