International organizations play a crucial role in shaping environmental policy by facilitating cooperation among nations, establishing norms, and providing frameworks for action. They often bring together diverse stakeholders to address complex global challenges such as climate change and biodiversity loss. Organizations like the United Nations Environment Programme (UNEP) promote initiatives, provide scientific assessments, and mobilize funding for environmental projects. Additionally, they can hold countries accountable for their commitments and encourage the adoption of sustainable practices. Ultimately, these organizations help harmonize efforts across borders, amplifying the effectiveness of global environmental governance.
