Climate change policy significantly affects international relations by influencing diplomatic negotiations, alliances, and conflicts. As nations face the effects of climate change, their stances on environmental policies can lead to collaboration or tension. Countries that adopt ambitious sustainability targets often find themselves aligned, forming coalitions such as the Paris Agreement. Conversely, those resistant to change may face international sanctions and criticism. The pursuit of energy independence or sustainable practices can reshape trade agreements and geopolitical strategies, as nations increasingly recognize that environmental issues transcend borders, necessitating collective action.
