OSPAR Beach Litter Monitoring in the Netherlands. Update 2024. Part I Status and Trends

In the year 2002, the Netherlands was one of the first countries to start with the monitoring of beach litter. This report provides an annual update of Dutch beach litter monitoring data and analysis results for the periods 2022-2024 (status analysis) and 2019-2024 (trend analysis), respectively. The statistical analysis was conducted in-line with the updated OSPAR CEMP (2025) guidelines and using the litteR software. The methods for beach litter monitoring and the results are no longer combined in one report since the 2023 update, but presented in two separate reports. This report is part I: Status and Trends.
