As the United Nations Climate Change Conference takes place on December 7 to 18 2009 in Copenhagen, Denmark, this special issue will focus on selected climate change education activities carried out by the ASP network around the globe. Climate change is one of the most urgent challenges of sustainable development and a key action theme in the UN Decade of Education for Sustainable Development (DESD). ASPnet schools around the world work on Climate Change Education in order to enable students to make informed and responsible decisions, turn passive awareness into behaviour change and make sustainable behaviours a daily habit. The development of good practices and innovative educational materials in climate change education is a key element in ASPnet’s strategy to meet the pressing educational needs of the future generation. This newsletter highlights only a few of the large number of activities of ASPnet worldwide.
