Ten key potential functions of the science-policy interface for plastic pollution, spanning across the four phases of the policy cycle – agenda setting, policy formulation, implementation, and evaluation – have been identified.
Agenda setting: This phase focuses on identifying potential threats, including emerging risks related to novel entities and legacy plastics. The Science-Policy Panel's horizon scanning function is instrumental in recognizing these challenges.
Policy formulation: Extensive scientific and technical support is essential in this phase. Scientific criteria for control measures, subsidiary bodies for chemical and product safety, and committees for assessing alternatives and non-plastic substitutes are crucial.
Broader Assessments is part of policy formulation. Comprehensive assessments of plastic pollution's impact on ecosystems, biota, and human health are necessary. The Science-Policy Panel, with its independence and intergovernmental nature, plays a pivotal role in providing credible information.
Implementation: This phase requires the development of expert working groups, the establishment of a knowledge management mechanism, and interdisciplinary data utilization. Collaboration between the plastics instrument and the Science-Policy Panel is essential.
Evaluation: Data-centric, this phase emphasizes global monitoring of progress and effectiveness. The plastics instrument is pivotal in reporting, monitoring, and data collection, supported by the development of an indicator framework and standardized methodologies.
Beyond these stages, capacity building and commutations act cross all policy phases.
