Implementing global governance poses significant challenges, including issues of sovereignty, differing national interests, and variations in economic capabilities. Countries may resist ceding authority to international bodies, fearing loss of control over their policies. Additionally, coordination among diverse nations can be complicated by cultural, political, and legal discrepancies. Compliance and enforcement mechanisms are often weak, making adherence to international agreements inconsistent. Furthermore, the complexities of addressing interconnected global issues, such as climate change or public health crises, necessitate cooperation amid competing priorities, requiring innovative approaches to promote collaboration and commitment.
