Executive Summary Marine plastic pollution is a significant part of the global plastic crisis. Since the 1950s, there has beenan exponential increase in the scale of global plastic production and use. Most plastics rapidly becomewaste because of their short lifespan, and most plastic waste leaks into the environment without propertreatment. A sizable amount of it ends up in the oceans, accumulating in various marineecosystems in unignorable quantities. If no intervention is made, the inflow and stock of marineplastics will keep growing. Marine plastic pollution has received attention from global environmental governance processes. TheUnited Nations 2030 Agenda for Sustainable Development and the Kunming-Montreal GlobalBiodiversity Framework of the Convention on Biological Diversity have identified the reduction ofmarine plastic waste as an essential element in combating marine pollution, achieving sustainabledevelopment, and protecting global biodiversity. The intergovernmental negotiations to reach a legallybinding instrument on plastic pollution control have also made the reduction of marine plastic pollutionone of their priorities. The root cause of marine plastic pollution lies on land. As the focus of early-stage intervention,land-based plastic pollution prevention and control has gained widespread attention and efforts. Thegoal of existing global plastic pollution treatment efforts is to achieve closed-loop management forplastics in their entire life cycle, from production, use to recycling, to prevent plastics from leaking intothe environment. However, this goal is far from being fully realized. Large quantities of plastics haveleaked into the terrestrial environment, some of which have eventually entered the ocean. Theseplastics are still accumulating in the ocean due to the failure of land-based waste management,threatening the marine environment. Therefore, this briefing focuses on the interception and removal of marine plastic waste (excludingmicro- and nanoscale plastics) despite the current focus on improving land-based management.Interception refers to intercepting plastic waste entering the ocean from land and ships (mainly throughfishing and shipping activities). Removal refers to removing plastic waste that has already entered theocean. This briefing identifies four critical interventions to achieve the interception and removal ofmarine plastic waste: intercepting plastic waste entering the ocean from the land, preventing fishinggear loss and discarding, preventing plastic waste dumping by ships, and removing floating plasticwaste in the ocean. This briefing analyzes these four critical interventions in terms of the followingaspects: the importance and features of the challenge, the relevant domestic an
