Given the important role of environmental amenities such as ecosystem services on human well-being, this study investigates the unfair distribution of access to urban cooling ecosystem services in Tehran in order to examine urban environmental justice through the following methodological steps: (1) mapping socio-economic inequality through eleven indicators reflecting socio-economic status ranked by TOPSIS, (2) exploring urban land surface temperature (LST) by applying the mono-window algorithm, (3) estimating canopy cover, and (4) applying distributional justice dimensions through demand, supply, and access to urban cooling ecosystem services. The results revealed that urban cooling ecosystem service demand was high in districts with lower socio-economic status ranking. Cooling ecosystem service supply was high in northern districts with higher socio-economic status. This study indicates that residents of Tehran are confronting urban injustice in terms of the distribution pattern of urban cooling ecosystem services.

鉴于生态系统服务等环境便利设施对人类福祉的重要作用，本研究调查了德黑兰城市制冷生态系统服务获取机会的不公平分布，以通过以下方法步骤来检验城市环境正义：(1) 绘制社会- 通过 TOPSIS 排名的 11 个反映社会经济地位的指标来衡量经济不平等，(2) 通过应用单窗口算法探索城市地表温度 (LST)，(3) 估计冠层覆盖，以及 (4) 通过应用分配正义维度城市制冷生态系统服务的需求、供应和获取。结果表明，社会经济地位排名较低的地区城市供冷生态系统服务需求较高。社会经济地位较高的北部地区，冷却生态系统服务供应量较高。本研究表明，德黑兰居民在城市降温生态系统服务的分布格局方面正面临着城市不公。
