In the 1980s, there were major international meetings to promote environmental education, just as there had been in the 1970s. Spain wanted to participate in actions adopted at these meetings by signing inter-ministerial agreements, organizing congresses, and promoting the work carried out by the Spanish National Institute for the Conservation of Nature (ICONA). Environmental issues were even tackled in school classrooms through seminars and talks with the aim of raising awareness of a problem that affected everyone and that would worsen as time went by. Our work attempts to analyze these political actions and events and, above all, to analyze how environmental issues were incorporated into textbooks. Despite all of the above, we found that the incorporation of environmental education into Spain's primary education curriculum and textbooks was not significant.
