In view of the concern with the insertion of critical environmental education in school, we seek theoretical-methodological contributions in critical historical pedagogy. In this sense, this article will address theoretical reflections that are born within the “Grupo de Pesquisa em Educação Ambiental” - Unesp-Bauru and that were issued during the 1st Symposium on Dialectical Historical Materialism and Research on Science Education and Environmental Education. Thus, we approach the question of the content of critical environmental education from the curriculum design of (...) critical historical pedagogy. Despite the question of the content and form of Environmental Education being present since its origins, we understand that the indepth debate on what should be its content in the school context is still absent. In this sense, assuming the school insertion of critical Environmental Education as the core of the curriculum is a way to overcome its limitations in theory and practice for the human formation necessary for social transformation.
