Plastic pollution has become a severe global crisis, posing grave threats to the environment, human health, and sustainable development. Driven by unchecked plastic production, the problem worsens through the entire lifecycle of plastics—from creation to disposal—releasing not only large debris but also microscopic particles, monomers, and thousands of chemical additives. These pollutants travel worldwide via air and water currents, damaging ecosystems and wildlife, including marine species that suffer from entanglement, ingestion, and toxicity. This editorial is part of a Special Issue "An effective plastic treaty for marine life".

The first policy brief of the EU-funded RESTORE4Cs project highlights the importance of European coastal wetlands in reducing greenhouse gas emissions and removing carbon from the atmosphere, promoting their restoration as a climate change mitigation solution.

The poster ‘Synergies and Strategies for Marine Protection and Climate Adaptation’ presents key results and approaches of research on the integration of marine protection and climate adaptation. It shows how these two areas can be linked in order to effectively meet the challenges of climate change in marine and coastal ecosystems.

This report focuses on the assessment of the status of the marine environment, the definition of environmental objectives and the development of programs of measures to achieve good environmental status. It provides guidance to Member States on the assessment of marine waters, identifies key pressures and pressures factors and offers approaches for setting environmental targets. It supports the development of monitoring programs and the implementation of measures to reduce pollution and conserve biodiversity. The technical assistance aims to promote cooperation between Member States and create a coherent framework for maritime policy in the EU.

This UNITED project business brief discusses the legal framework and environmental implications of a project in the Greek Aegean combining aquaculture and tourism, including laws and regulations, particularly in relation to marine conservation, permitting and marine spatial planning.

This UNITED project business brief discusses the legal framework and environmental impacts of a project in the German North Sea that combines offshore wind energy and aquaculture, including the laws and regulations that apply to offshore installations in the German Exclusive Economic Zone (EEZ).

This Business Brief of the UNITED project examines the legal and environmental aspects of a project that successfully combines offshore wind energy production with innovative tourism activities.

This UNITED project business brief examines the legal and environmental aspects of a Belgian project using offshore wind farms in the North Sea for the cultivation of flat oysters and seaweed. Particular attention is paid to environmental benefits, such as improved water quality and biodiversity, as well as potential challenges, including permitting procedures.

This policy paper addresses the restoration of marine and coastal ecosystems. It advocates for synergies among UN decades and underscores the need to integrate various approaches to restoring marine and coastal ecosystems.

The Mission Ocean and Waters service portal is now live and serves as a comprehensive one-stop-shop for stakeholders, offering essential tools, contacts, knowledge, matchmaking, financing, and support for the successful execution of the EU Mission "Restore our ocean and waters by 2030". The service portal ensures access to knowledge for all citizens while extending support and technical assistance to Mission Partners actively involved in the Mission Ocean and Waters implementation.

This report elaborates the main challenges faced by water management institutions in implementing e-flows in EU Member States, presents country progress in developing relevant good practices and presents relevant implementation examples.

As competition for, and interest in, use of ocean space increases, a need for management arises to optimize activity in marine areas. This policy brief provides a comprehensive consideration of the economic efficiency of marine multi-use (MU) by weighing the pros and cons of individual use options against potential MU combinations.

This article illustrates the communication strategies that were successfully applied in the citizen science program Plastic Pirates in Germany. The program engages schoolchildren, teachers and youth groups in plastic pollution research. A variety of communication strategies have been implemented and continuously revised and adapted since the start of the program in 2016.

This article, co-authored by Mandy Hinzmann and Linda Mederake from Ecologic Institute, assesses the potential of the EU "Single-Use Plastics Directive" (SUPD) to reduce litter pollution in the environment with three scenarios. The scenario analysis revealed that the success the current SUPD can be an important first step, yet further legislative actions are needed to effectively prevent plastic waste pollution - bans alone are not sufficient. The success of the Directive is therefore highly dependent on implementation and enforcement.

This policy brief explores the potential and benefits of marine restoration, as proposed in the regulation. Marine and coastal ecosystems are immensely important for biodiversity and human well-being. Restoring marine areas can enable the respective ecosystems to (once again) perform their natural functions, improving their overall health and resilience.

Since we learned how to produce plastic, humans have manufactured more than 8.3 billion tons of it – most of which ended up as waste somewhere on the planet. This leads plastic waste to enter the landscape, rivers, beaches, and eventually ocean. We asked our listeners what, in their opinion, is the issue with plastic pollution. The answers ranged from negative impacts on human health and the environment to lack of recycling infrastructure and the global dimension of the plastics problem.

This study analyses the objectives, targets and activities of the EU Mission 'Restore our ocean and waters by 2030'. It proposes a draft set of indicators for measuring the Mission's progress, maps major stakeholders and networks, and offers recommendations for the future implementation of the Mission.

The postcard series was created for the EU4Ocean Coalition for Ocean Literacy project in order to give the initiative more visibility.
