What evaluators will look for in this topic

Expected outcomes

Projects should contribute to all of the expected outcomes.
For each outcome (EO1 to EO4), name who will use or adopt your results (a specific group, not “industry” or “society”), how they get them, and the indicator that shows the change, with baseline, target and date.
Use the topic's own words for each outcome, so the evaluator can tick it off.

What the scope asks for

Evaluators check the proposal against these sentences of the scope. Answer each one visibly, in the call's own words.

“The European Water Resilience Strategy and the European Ocean Pact further emphasize the need to enhance the resilience of European waters to human-induced pressures.”
“Actions should address all of the following aspects:.”
“Relevant TRL5 demonstration of such systems should be done.”

Conditions that shape the proposal

Part B, sections 1–3: 45 pages (standard application form). Text beyond the limit is not read; tables and figures count.
Lump sum: the budget is fixed per work package and paid when each work package is completed. Every work package needs activities and deliverables an evaluator can verify, and the effort must match the money.
TRL: the topic expects TRL 5 by the end of the project. State where you start and the evidence for it.

Impact pathway and traps

The scope expects pilots or demonstration. Name the sites, the partners who run them and what is measured there.
Keep outputs, outcomes and impacts apart: what you deliver, what changes when others use it, and the long-term effect.
For each destination impact you claim, show which of your outcomes feeds it. Destination impacts are long-term effects, not project deliverables.
Name the barriers outside the project (regulation, markets, user behaviour) that could block uptake, and what you will do if they do.
Section 2.3 (the summary canvas) is optional on this call; the old split into scientific, economic and societal impact is no longer required.

The scope, as published

The European Union aims to protect and conserve its marine and freshwater environments by achieving Good Environmental and Good Ecological Status. The European Water Resilience Strategy and the European Ocean Pact further emphasize the need to enhance the resilience of European waters to human-induced pressures. Projects like the Horizon Europe EMERGE have researched the impacts of shipping on marine ecosystems. The introduction of technologies to decarbonize the sector may enable, to a certain extent, to phase-out relevant current sources of water and air pollution. However, renewable low and zero-carbon fuels and procedures pose new risks to marine and other aquatic ecosystems like rivers and lakes yet to be explored and addressed, both from the normal function of waterborne transport and from accidental spills of renewable low and zero-carbon fuels. In addition, other pollution sources can be addressed today. This topic aims to evaluate, forecast, control and mitigate the impact of waterborne transport on marine and other aquatic ecosystems, with a focus on developing and demonstrating innovative abatement and mitigation systems and strategies to mitigate and eliminate, where possible, the harmful impact of waterborne transport in the ocean and inland waters. New technologies and solutions addressing the decarbonization of waterborne transport will be considered, as well as the potential risks and challenges associated with these. Actions should address all of the following aspects: Evaluate and forecast the environmental impacts of waterborne transport operations on marine, rivers and other aquatic ecosystems, in particular regarding the effects of renewable low and zero-carbon fuels (with particular attention to accidental spills) and related technologies. The proposal may include testing and experimental work in relation with spills. Develop and demonstrate effective response scenarios, including the associated abatement technologies and any potential new innovative equipment, for managing uncontrolled releases of renewable low and zero-carbon fuels in marine and inland waters or in port areas, including dedicated specific procedures and operational guidelines. Modelling scenarios on water and air pollution sources from each ship types and services running on renewable low and zero carbon fuels. Develop and demonstrate innovative and cost-effective abatement and mitigation systems and strategies to prevent, eliminate and reduce the harmful impacts of the use of renewable low and zero carbon fuels. Relevant TRL5 demonstration of such systems should be done. Identifying training needs and skills requirements to deploy developed solutions, as well as in relation to the management and use of renewable low carbon fuels in ports and on vessels in marine and inland waters, including relevant emergency response preparedness. Develop and demonstrate solutions that improve the resilience of European waters to climate change, pollution, and other human-induced pressures, and contribute to achieving Good Environmental Status and Good Ecological Status in European waters, as well as the objectives of the European Water Resilience Strategy and the European Ocean Pact. Strengthen stakeholder engagement by involving environmental, industry and academic associations, to foster inclusive, future-focused environmental responsibility through sustainable practices. This topic implements the co-programmed European Partnership on ‘Zero Emission Waterborne Transport’ (ZEWT). As such, projects resulting from this topic will be expected to report on results to the European Partnership ‘Zero Emission Waterborne Transport’ (ZEWT) in support of the monitoring of its KPIs.
