According to neo-institutionalism concerns for environment and sustainable development, borne by INGOs and IGOs, have become a part of a more or less standardized World Culture. An indicator of this culture can be seen in the widely spread Agenda 21, emerging out of the 1992 Conference on Environment and Development in Rio de Janeiro (“Earth Summit”) organized by the UN, and also the United Nations Decade of Education for Sustainable Development (2005-2014), in which environmental educational issues have become a visible part of the World Culture. This chapter deals with the implementation of the educationalized environmentalism in Sweden, using WWF and its relevant activities as case study. The aim is to shed light on how the global movement of sustainability takes nationalistic features when it is transformed through the Swedish school culture. Of crucial importance will be the analysis of WWF’s teaching material be used in the educational efforts to “save the world”, indicating a globally responsible sustainable citizen on one hand, and an emphasis on the Swedish exceptionalism on the other. Through this, we intend to discuss how national identity – and a new kind of national pride – is constructed through education for global citizenship.
