Environmental education in Poland has a long history, but has advanced especially in recent years. The need to implement it within systems of formal and non-formal education is noted in many government documents. The educational reform introduced in 1999 changed the goals and methods of teaching environmental education in the school system. At present it is taught at every grade level. According to regulations it is to be incorporated within all subjects, mainly in the sciences and also as an interdisciplinary environmental education track. This paper describes how environmental issues are taught and what results are achieved in Polish schools.
