Applying this concept is valuable because it ensures just distribution of resources and efficient allocation among citizens. The paper question is what are the economic, social and environmental dimensions of a just city? It adopts an inductive theoretical methodology. It is based on secondary data analysis research design. It is divided into six parts: introduction, definitions, justice dimensions, advantages of justice and disadvantages of injustice, reasons and consequences of urban injustice and finally the conclusion. This paper ends with some conclusions: many cities all over the world suffer from urban injustice. As a result, social problems appear such as segregation, alienation and higher crime indicators. From economic perspective there are disparities in opportunities, income level and wealth. And from environmental perspective there are disparities in quality of environment such as pollution indicators, access to green public spaces and quality of urban life. There is also injustice in public services distribution like education, healthcare, urban public spaces, public transportations, infrastructures and so on. These public services could be used as an indicator of urban justice. This paper gives some recommendation: all people should be integrated in urban production process. All people should have equitable access to all public services, opportunities and high quality of life specially marginalized groups. To guarantee them sufficiency of their human rights, and life without conflicts to move towards a more just world.
