MARLISCO's activities improved the knowledge of target groups on the problem of marine litter and commitment in being part of the solution.
National stakeholders' networks have been strengthened.
A database of practices to prevent marine litter and “what/how to” guides have been made available.
A multilingual teaching resource and Serious Game for youngsters in 15 languages were developed.
Stakeholders favour preventive measures and Reduce, Reuse and Redesign strategies.
