Environmental justice is the idea that all people should be treated fairly in decisions about the environment. It involves how resources, land use, and environmental policies affect different communities. Communities, governments, and organizations take part in these decisions. Environmental justice focuses on fair treatment across groups.

This concept applies in societies around the world, in both local and global situations. It can be seen in cities, rural areas, and regions facing environmental changes. Different communities may be affected in different ways by environmental conditions.

Environmental justice became a recognized movement in the late 20th century. It continues today as part of discussions about environmental decisions and policies. It is part of how societies organize and address environmental issues.
