Education plays a key in Environmental protection and curriculum development. After the Curriculum Reform in 2001, Taiwan's formal curriculum for environmental education in schools was included as a "major issue" in the National Curriculum. This course will be extended to a total of 12 years of national education. Re-education once again incorporated the domain outline with major issues. The main idea of this paper was to review what had been done for the curriculum integration of environmental education and to explore the problems. Based on the review of the past, the authors propose what can be done for the new curriculum reform to achieve a win-win situation.
