“The newly-published EU Coastline Macro Litter Trend report found that the amount of marine macro litter (items bigger than 2.5 cm) in the EU coastline has dropped by 29 % between the baseline period (2015-2016) and the assessment period (2020-2021). 

While the largest reduction in terms of percentages is seen at the Baltic Sea (45%), major efforts at the Mediterranean and the Black Sea have led to impressive reductions in absolute numbers of litter items on the beaches (figure below).”
