Chang Juu-en (Chinese: 張祖恩; pinyin: Zhāng Zǔ'ēn; Pe̍h-ōe-jī: Tiuⁿ Chó͘-un; born 1951) is a Taiwanese engineer who served as Minister of the Environmental Protection Administration from 2003 to 2005.
Chang began teaching at NCKU in 1982, and was named deputy minister of the Environmental Protection Administration under the leadership of Hau Lung-pin in April 2001.
[3] Upon taking office, Chang pushed the government to build more incinerators,[4] a recommendation that incited severe backlash across Taiwan.
[7][8] Chang was criticized in 2004 for proposing an expensive three-year action plan during an election year, as it was not a guarantee that he would be retained.
[11] Chang resigned in April 2005 and returned to teaching at National Cheng Kung University.
