This article will investigate the philosophy of science of Roy Bhaskar (1944-2014) as a coherent basis for environmental education. The work of Bhaskar serves as an in-depth approach to understanding how to apply critical realism (the critical and the realist) to matters such as environmental education, because he concretely theorises the connections between science, social change and metaphysics. By mobilising key Bhaskarian motifs -- that is, the primacy of ontology over epistemology, the laminated system as a means to understand reality, the ways in which inquiry may be organised through the real, actual and the empirical, and the positive application of dialectics -- this article constructs a new approach to environmental education and positions it in the field of environmental education by comparing it to posthumanism and the new materialisms. This article contains inquiry-based study outlines for enhanced thinking around: (1) climate change and social justice; (2) movements towards a carbon-free economy; (3) water, food and population; and (4) the future of human habitation.
