While this appears some way off in most of the focus countries, many have taken an important step by including ESD content specifically in their K-12 curricula, which should in turn influence what gets included in teacher education curricula. While universities like UWI and USP are responding by mainstreaming and mandating ESD in their programmes, it is important to keep in mind that including ESD content is not the same as a true reorientation of the educational process. In teacher education for sustainable development, as in other ESD, the objective is to put in practice a new and more active and sustainability-oriented vision of education, rather than adding to that which is already in place.
