Climate change policy impacts international relations by shaping cooperation and conflict among nations. As the effects of climate change become more pronounced, countries must address issues like resource scarcity and migration, often requiring collective action and global agreements. Policies aimed at reducing greenhouse gas emissions or transitioning to sustainable energy can foster partnerships, but they may also create tension, particularly when nations prioritize national interests over global commitments. Additionally, climate change can exacerbate existing geopolitical tensions, necessitating a collaborative approach that balances environmental sustainability with economic and security concerns.
