Abstract

This article analyzes how Brazil has responded, in normative and institutional terms, to
the commitments assumed under the international regime for combating plastic pollution
in the marine environment. Based on the theoretical frameworks of international regimes
and two-level games, the study examines the international legal instruments ratified by
Brazil, such as UNCLOS and MARPOL, as well as their articulation with domestic laws
and policies, such as the PNRS and bills addressing plastic pollution. The findings indicate
that, although there have been legal advances and Brazil has actively participated in
international negotiations, contradictions and challenges persist in domestic implementation,
especially those related to the low recycling rate, economic interests, and difficulties in
federal coordination.
