The Trump–Putin summit in Anchorage underscored shifting geopolitical dynamics with far-reaching consequences for sustainable development. While dominated by the Russia–Ukraine war, its implications extend to energy security, climate goals, food supply chains, and global cooperation. Agreements hinting at fossil fuel dependency, U.S. security guarantees to Ukraine, and weakened multilateralism risk slowing progress on the SDGs. With disruptions to trade, aid, and decarbonization, the summit highlights the need for vigilant international advocacy for sustainability, inclusivity, and cooperative governance.
