The Role of International Environmental Law in Regulating Global Carbon Emissions: A US-Centric Analysis of Treaty Effectiveness and Policy Implementation

International environmental law has evolved significantly over the past three decades, with carbon emission regulation emerging as one of the most critical challenges facing the global community. This article examines the effectiveness of international treaties, particularly the Paris Agreement, in regulating carbon emissions and combating climate change from a United States perspective. Through comprehensive analysis of treaty mechanisms, implementation challenges, and policy outcomes, this study evaluates how international legal frameworks have shaped US energy policies and influenced carbon footprint reduction across various industries. The research reveals that while international environmental law provides essential frameworks for global cooperation, significant gaps remain between treaty commitments and actual emission reductions, particularly in the United States' approach to international climate obligations.
