This study investigates global disparities in urban residents' access to greenspace, focusing on the contrast between Global North and Global South cities. Utilizing high-resolution population and greenspace data, the researchers find that Global South cities exhibit significantly lower greenspace exposure (one-third the level of Global North cities) and substantially higher inequality (nearly double the Gini coefficient). The study quantifies the contributions of greenspace provision and spatial configuration to this disparity, highlighting the urgency of prioritizing greening policies to address environmental inequalities and advance sustainable development goals.
