The United Nations Sustainable Development Goals (SDGs) are a set of 17 interconnected goals adopted in 2015 to end poverty, protect the planet, and ensure peace and prosperity by 2030. The SDGs cover social, economic, and environmental issues, including no poverty, zero hunger, good health and well-being, quality education, gender equality, clean water and sanitation, affordable and clean energy, decent work, economic growth, and more. To support these objectives, a knowledge graph called SustainGraph has been developed to provide insights and recommendations for improving sustainability performance. SustainGraph is an open-source project that utilizes various data sources and sustainability metrics to track information related to the achievement of SDGs at national and regional levels. The project aims to create a unified source of truth for information related to the SDGs, using graph databases and natural language processing and machine learning techniques. A demo of SustainGraph was presented during a livestream, showcasing its capabilities in visualizing data and providing insights into how different policies impact the SDGs. As of now, the knowledge graph consists of 5M nodes and 10M relationships, with plans to include more resources in the future.
