Different types of urban green spaces provide diverse benefits for human health and environmental sustainability, but most studies on access to green space focus on neighborhood parks, with less work on smaller or larger green spaces. In this study, we examined sociodemographic differences in access to green spaces of different sizes for 14,385 census block groups in 12 U.S. cities using a 'just sustainabilities' framework. We classified green spaces into street-level greenery (XS), neighborhood parks (S-L; walking and cycling access), and large parks (XL; walking, cycling, and driving access). We ran spatial filtering models at the census block group level using different thresholds based on transportation modes. We uncovered a complex picture of inequality, with consistent injustices for XS green space, and fewer injustices for S-L and XL green space based on socioeconomic status and age, and some instances of just distributions for S-L and XL green space based on race/ethnicity. Our findings present a concerning picture for 'just sustainabilities': the green space type that is most often part of sustainability and climate adaptation strategies-street greenery-is unjustly distributed, likely as a result of structural racism in U.S. institutions. By examining multimodal access to green spaces of different sizes, this study helps urban greening professionals develop more just and sustainable strategies.
