This research had as objectives to describe and analyze the environmental approach in chemistry textbooks approved by the National Program of Textbook for high school (PNLEM/2007). This investigation is about a content analysis performed with the aid of three categories created based on the fundamental principles of environmental education as expressed in the Belgrade Charter (1977). Before the proposed by the reference document, the research sought to identify some elements related to environmental education, such as: treatment of social, political, economic, cultural and scientific environmental issues. The results showed that all books reviewed presented the environmental theme through different approaches. The readings, together with data organization, have enabled the creation of a thematic map and a descriptive framework that listed the themes found in each Textbook, as well as its distribution in different chemical content. The analysis identified some aspects, constructed with elements of the Charter Belgrade, within the categories scientific knowledge, knowledge/awareness and participation. In the first category were identified and analyzed aspects concerning the relationship of the content with the environment, the limitation of science face to the environmental challenges, the importance given by Textbook to the scientific knowledge for environmental understanding, the importance of knowledge and technology in the service of human needs. In the second one, knowledge/awareness, the analysis identified social, behavioral, economic and political aspects of the environmental issues. In the Participation category, aspects about the development of sense of responsibility and evaluation capacity were identified, in addition to raising awareness. The survey concluded that some environmental issues are treated in a decontextualized way by shredding the dimension of environmental problems which can reduce the complexity of the relationships between humanity and nature. Although not all books embrace all the principles of Belgrade Charter and even though there is an overestimation of the value of scientific knowledge to the detriment of other determinants for current ecological condition, it is concluded in this survey that the chemistry textbooks can contribute to achieve environmental education in Brazilian schools emphasizing the need for studies about the relationship between the triad components "scientific contents, teacher training and textbook" as one of the relevant aspects to effective consolidation of environmental education in the formal education.
