The impact of the climate crisis on urban environments and life within them is evident. In the face of challenges like heatwaves, pollution, and declining quality of life in cities, there is a growing demand for the preservation and expansion of urban green spaces, often driven by citizen-led initiatives. Citizens, either independently or in cooperation with other urban stakeholders, preserve and enhance green areas. This paper explores the intersection of green and digital transformations within public policy, focusing on the examination of smart technologies for promoting and monitoring urban greening efforts. The study specifically evaluates 100 urban greening initiatives initiated or supported by citizens globally, categorizing them according to the type of greenery, the stakeholders involved in the initiatives, the mode of implementation and the use of digital tools incorporated towards 1. community engagement 2. data collection, analysis and monitoring 3. expanding and scaling up those efforts. We notice variations in green endeavors based on the stakeholders spearheading them, and classify the methods of cooperation among government bodies, citizens, NGOs, and the private sector. In terms of technological use, we primarily find websites and social media platforms easing participatory endeavors and the formation of partnerships. As cities continue to grow, integration of more advanced digital technologies in the future could enable accurate and real-time assessment of green spaces, inform evidence-based decision-making, and streamline processes in scaling up green initiatives.
