In light of the recent COVID-19 pandemic, climate change, and diseases of civilization caused by stress and the pace of life, it is crucial to ensure that all urban residents have access to attractive green spaces. Such accessibility should be equal for all groups, not only for the privileged (more affluent) residents but also for those of lower socioeconomic status and the most vulnerable groups (children, the elderly, and the disabled). We can divide green spaces into two types: formal green spaces (designed and managed parks, allotments, or special gardens, e.g., botanical gardens) and informal green spaces (e.g., meadows, wasteland, conservation greenery). Both types of green spaces should be treated equally because they provide a whole range of benefits to residents, that is ecosystem services (e.g., improving microclimate, reducing urban heat island, relaxation, physical activity, strengthening human ties). It is worth mentioning that green spaces can also be a smaller green infrastructure, for example, green walls, vertical gardens, rain gardens, and green bus stops. Such solutions will work well in compact city centers, where space is limited and must serve a variety of functions. <!----> <!----> <!----> <!---->
