National Implementation Plans and National Action Plans: Key Elements to Consider in the Context of a Treaty to End Plastic Pollution

The document analyzes different national implementation mechanisms for multilateral environmental agreements (MEAs) to provide recommendations for the negotiations of a plastics treaty. It distinguishes between National Action Plans (NAPs), which are typically broad and voluntary strategic documents, and National Implementation Plans (NIPs), which are precise, legally binding road maps for meeting treaty obligations. The authors argue that NAPs often suffer from a "lack of performance" and "insufficient ambition," whereas NIPs are more effective at identifying gaps and mobilizing resources. The brief specifically warns against adopting the NDC model used in the Paris Agreement, stating that unilaterally determined targets are "woefully inadequate" and should not be used for the plastics treaty. Instead, it recommends a hybrid approach combining NIP and NAP characteristics, supported by clear language, effective monitoring, and technical and financial assistance, particularly for Small Island Developing States (SIDS) and Least Developed Countries (LDCs).

• National Action Plans (NAPs) are broad, non-binding policy documents that allow governments to identify gaps and reforms, but they are limited by a lack of legal obligation, insufficient ambition, vague scopes, and poor monitoring and compliance.
• National Implementation Plans (NIPs) are legally binding requirements under MEAs that serve as precise road maps for how a country will meet treaty obligations, including the identification of resources and the designation of implementation agencies.
• NIPs and NAPs are complementary rather than exclusive; NIPs provide the operational and legal framework, while NAPs provide the broader strategic component.
• The model of Nationally Determined Contributions (NDCs) from the Paris Agreement is unsuitable for the plastics treaty because unilateral determination of ambition leads to inadequate collective results.
