In the face of the socio-environmental crisis in which we are immersed, the initial training
of teachers must assume the work in favor of a critical, committed, participatory citizenry capable of
responding to the socio-environmental problems of the current and future world. The analysis of the
initial 61 research projects on socio-environmental problems of four classes involving 240 students of
the Degree in Early Childhood Education at the University of Seville (Seville, Spain) is presented.
Under an interpretive descriptive approach according to a category system based on the Sustainable
Development Goals (SDGs) established by the UN (2015) and its targets, we can learn about their
socio-environmental concerns and how they relate to the current 2030 Agenda. We obtain that of the
17 SDGs, around half of the final 42 research projects analyzed focus on sustainable consumption and
project patterns and climate change, while problems related to poverty, hunger, or peace do not arise.
In addition to allowing us to draw a portrait of the socio-environmental concerns of early childhood
preservice teachers, the data obtained also gave us the opportunity to ponder the didactic possibilities
that these types of formative activities bring to the training of teachers who are critical and committed
to transforming the world.
