International agreements play a critical role in environmental policy by establishing frameworks for cooperation and setting binding targets for countries to reduce their ecological footprints. Instruments like the Paris Agreement facilitate global commitment to combat climate change by encouraging nations to adopt sustainable practices. These agreements often foster transnational collaboration, enabling knowledge transfer and technology sharing, which can be vital for developing nations. Compliance and enforcement mechanisms, while often challenging, help hold countries accountable. They can also serve to align national policies with global sustainability goals, thereby enhancing the effectiveness of local environmental initiatives.
