ecosystem services including fisheries, transportation and even tourism. Targets, indicators and progress The UN has defined 10 targets and 10 indicators for SDG 14 that include preventing and reducing marine pollution and ocean acidification, protecting marine and coastal ecosystems, and regulating fishing. The targets also call for an increase in scientific knowledge of the oceans. Some targets have a target year of 2020, some have a target year of 2025 and some have no end year. The ten targets include reducing marine pollution (14.1), protecting and restoring ecosystems (14.2), reducing ocean acidification (14.3), sustainable fishing (14.4), conserving coastal and marine areas (14.5), ending subsidies contributing to overfishing (14.6), increase the economic benefits from sustainable use of marine resources (14.7), increase scientific knowledge (14.a), supporting small scale fishers (14.b) and implementing and enforcing international sea law (14.c). Most SDG 14 targets are not measurable in quantitative terms because the data is not available yet; only target 14.5 is quantifiable. Target 14.1: Reduce marine pollution The full title of Target 14.1 is: "By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution." It has one indicator: Indicator 14.1. is the "Index of coastal eutrophication and floating plastic debris density" The "Index of Coastal Eutrophication (ICEP), refers to the inputs of nutrients (nitrogen, phosphorus and silica, in different forms) from rivers, and corresponding nutrient-ratio sub-indicator." The methodology for ICEP will be developed and ready by 2020. No data is available for this indicator yet. The "Floating Plastic Debris Density" refers to the modelled macro and micro plastics distribution in the ocean. If the quantities of floating micro is below 4.75mm, it is labeled as micro and if it is over 4.75 cm, it is labeled as macro. The amount of plastics in large marine ecosystems are measured based on "a model of surface water circulation and the use of proxy inputs". The final Floating Plastics Debris Density indicators will be ready by 2020. Despite pervasive global pollution from plastics, there is only one indicator (14.1.1b) under Goal 14, specifically related to reducing impacts from plastics. For all other sustainable development goals, there is no specific target in decreasing microplastics due to limitations of data. Furthermore, there are no targets in reference to reducing microplastics, thus presenting a large challenge for governments to report and monitor microplastics in the environment. Marine pollution
