One of the major challenges we are faced with today is to build an environmentally sustainable society and to promote ESD (Education for Sustainable Development) in the fields of education. This study analyzes the environmentally related content of Home Economics textbooks, extracting words related to the environment. For our analysis, we used nine different high school textbooks published in 2007 and 2013. Categories we used for our analysis were “laws,” “environmental labels,” “consumer life and environment,” “dietary habits and science,” “clothes and human life,” and “living environment.” Along with our analysis, we also focused on the idea of LCA, discussing what needs to be done in this area of education. The findings of our study are as follows: 1. Authors of textbooks have in recent years attached greater importance to the relationship between the environment and lifestyle. 2. In the textbooks published in 2013, the number and variety of words associated with the environment has increased from those published earlier. 3. We were able to recognize the trend of LCT widely presented in textbooks.
