The environmental justice movement arises to enforce the implementation of the right to health and a healthy environment for the citizens, as a conception of social claim, a new paradigm that provides certainty and balance on the distribution of the positive environmental implications or negative in a given territory. However, with the passage of time, environmental justice apparently has been uprooted from the political, legal, administrative and social imaginary, and although it has been inserted in legislative documents, government programs, and in the field of organizational structures of public entities, in reality does not reflect the principles that gave birth to the movement and, as an example, a study case is shown where is proven that thirty years after environmental justice's birth, there is still so much to do to really apply it.
