Methodological developments (protocols, thresholds or integration rule) and the acquisition of additional data are necessary to be able to assess the status of the D10C1 criterion. The indicators relating to this criterion are considered operational because the collection or observation protocols and the methods for calculating the metrics have been mastered. However, the lack of thresholds and long data series does not allow to conclude whether the GES has been achieved or not. In addition, developments are underway to harmonise the MSFD categories and the OSPAR categories, which will allow the three parameters relating to the quantities of waste on the shoreline, floating waste and waste on the bottom to be integrated for the next assessment by category. The methodological standards relating to this criterion will be specified following further studies, as provided for in Ministerial Order 2019 on the definition of good environmental status of marine waters.

Concerning criterion D10C2, three indicators are being developed, namely "Micro-waste on the shoreline", "Floating micro-waste" and "Micro-waste in bottom sediments". However, the indicators "Micro-waste on the shoreline" and "Micro-waste in bottom sediments" could not be assessed due to the lack of operational protocols and the indicator "Floating micro-waste" could not be assessed due to the lack of data and the absence of a threshold for the parameter "Quantity (number) in water" of micro-waste. The methodological standards for criterion D10C2 will be further developed following further studies, as provided for in Ministerial Order 2019 on the definition of good environmental status of marine waters.

Concerning criterion D10C2, three indicators are being developed, namely "Micro-waste on the shoreline", "Floating micro-waste" and "Micro-waste in bottom sediments". However, the indicators "Micro-waste on the shoreline" and "Micro-waste in bottom sediments" could not be assessed due to the lack of operational protocols and the indicator "Floating micro-waste" could not be assessed due to the low number of samples in this MRU. The methodological standards relating to criterion D10C2 will be specified following additional studies, as provided for in Ministerial Order 2019 on the definition of good environmental status of marine waters.

Concernant le critère D10C2, trois indicateurs sont en cours de développement, il s'agit des indicateurs "Micro-déchets sur le littoral", "Micro-déchets flottants" et "Micro-déchets dans les sédiments des fonds". Toutefois, les indicateurs "Micro-déchets sur le littoral" et "Micro-déchets dans les sédiments des fonds" n'ont pu être évalués faute de protocoles opérationnels et l'indicateur "Micro-déchets flottants" n'a pu être évalué dans son ensemble en raison de l'absence de seuil pour le paramètre "Quantité (nombre) dans l'eau" des micro-déchets. Les normes méthodologiques relatives au critère D10C2 seront précisées à la suite d’études complémentaires, comme le prévoit l'arrêté ministériel 2019 relatif à la définition du bon état écologique des eaux marines.
