The purpose of the work was to analyze and describe how the concept of sustainable development is presented and changes over time from the 1994 curriculum to the 2022 curriculum. By comparing teaching materials from a period of nearly 30 years, there is the opportunity to see how the books presented sustainable development in different ways. What is also examined is how the teaching materials relate to current curricula and are influenced by these in their content. The method used was a teaching materials analysis with a structural perspective where the curricula were the external factor that affects the teaching materials based on the three dimensions of sustainable development (ecological, economic and socially sustainable development). A thematic analysis was used in the work with the material. The result of the study was that the concept of sustainable development has undergone a major change in its presentation and how much importance has been placed on the concept in current curricula. In the first curriculum for the study Lpo94 there was some focus on sustainable development, but as knowledge in society was low, no direct measures or proposals were found to achieve a change. For the later curricula, the concept has received a greater and wider explanation in the social debate, which has led to the teaching materials highlighting more about the three dimensions of sustainable development. The most important thing the study came to is that it is possible to see that there have been changes from Lpo94 to Lgr22 in how sustainable development is presented and how much importance is placed on the concept in teaching materials. At the same time, it is found that the teaching materials do not manage to capture all points within the curricula, which places great demands on teaching teachers who must analyze the curricula and then select teaching materials and discover which parts are not covered and must be taught in addition to the chosen teaching materials.
