International treaties play a vital role in shaping environmental policy by establishing binding commitments among countries to address issues like climate change, biodiversity loss, and pollution. These agreements often involve specific targets and cooperative efforts to manage shared resources and mitigate environmental impacts. Successful treaties can lead to significant advancements in national policies, encouraging the adoption of sustainable practices and technologies. Furthermore, they promote global dialogue and collaboration, essential for tackling transnational environmental challenges that no single nation can resolve alone.
