プレゼンテーション

This presentation was a quick overview of monitoring and scientific research on marine plastics and pollution. The whole information is based on “G20 Report on Actions Against Marine Plastic Litter” 2019, 2020, 2021, and 2022.
 

The major findings from the quick review are as follows: 1) It seems that the current policy attentions is still more on monitoring of direct plastic litter and environmental impacts. 2) Upstream (product and material-related) monitoring and downstream monitoring (water-way, waste, and marine and coastal environment) are not integrated well. 3) Top-down assessment/estimation based on life-cycle approaches and material flow assessments are available but may not been widely used for policy assessment and decision making. 4) Capacity development on utilizing indirect methodologies and life-cycle approaches/material flow assessments for policy purposes is necessary. 5) At least at policy makers level, utilization of DX or AI is not widely recognized as promising methodologies yet for monitoring purposes.
