There are many campaigns for the protection of the planet, there is news of global warming, the phenomenon of the girl and the boy, but still people continue to generate actions that harm the environment. The objective is to determine if it is enough to have an environmental conscience to generate environmental actions. For this process a systematic review was carried out that resulted in 10 scientific articles divided into three categories, one where environmental awareness is compared with ecological behaviors, in the other they are articles that conduct psychological and behavioral studies and finally studies that perform actions with the community to improve their ecological behavior. It could be concluded that environmental education is necessary to generate environmental actions, it is not enough to have an environmental awareness, as this should be reflected in everyday behaviors.
