In 2022, the growing impacts of climate change have been felt across the globe, from prolonged drought in the Middle East and North Africa, to erratic monsoons in South Asia and record-breaking heat waves in Europe and China. At the same time, the COVID-19 pandemic—which reached the tragic milestone of one million deaths within the first eight months of this year—and the ongoing war in Ukraine and other violent conflicts have impeded global progress toward the Sustainable Development Goals. To address these and other pressing global challenges, in his 2021 Out Common Agenda report, UN Secretary-General António Guterres called for a Summit of the Future to improve collective action worldwide. Among the summit’s anticipated outcomes are a Declaration on Future Generations, a Global Digital Compact, and a New Agenda for Peace. This report elaborates on the challenges, proposed major elements, and potential spoilers to be overcome by each of these global policy frameworks. It further argues that meaningful civil society engagement in the summit’s preparations can reassure all stakeholders that decisions taken in September 2023 are well-informed, enjoy broad social ownership, and generate a sense of co-responsibility in supporting their implementation.
