The role of environmental policy in international relations is increasingly significant as global challenges like climate change, biodiversity loss, and pollution cross national borders. Countries engage in collaborative efforts through treaties and agreements, such as the Paris Agreement, to mitigate environmental issues. These policies aim to establish standards and regulations that guide nations toward sustainable practices, thus promoting global cooperation. Furthermore, environmental policy can lead to trade relations or conflicts when countries have differing standards or interests. Ultimately, effective environmental policy aligns with broader international security and economic stability goals.
