This report builds on the recent work convened and carried out under the umbrella of the UN Department of Economic and Social Affairs (UNDESA) and the United Nations Framework Convention on Climate Change (UNFCCC). This work grew out of global conferences designed to promote synergistic action between the Sustainable Development Goals (SDGs) and the climate agendas, the Copenhagen Conference in 2019, the Webinars of 2020 and 2021 hosted jointly by the UNDESA and UNFCCC, the Third Global Conference on Synergies of 2022 hosted by the Government of Japan, and subsequent global conferences at UNHQ in New York (2023), Rio de Janeiro, Brazil (2024) and Copenhagen, Denmark (2025). These global conferences provided the platform, rationale and urgency for the work which has been undertaken since 2023 with the involvement of a distinguished Expert Group convened by UNDESA and UNFCCC, representing several disciplines and regions of the world.
