During his presidential campaign, Ma participated in one of the debates that discussed many topics, including environmental protection. The Taiwan Academy of Ecology evaluated the policies of both candidates Hsieh and Ma, and the secretary of its workstation in Taipei said that both candidates failed their expectations, but they had more hope for Hsieh than Ma because Ma's environmental concepts lack considerations of reality. In February 2008, several environmental groups created a list of commitments for the two candidates to sign. DPP candidate Frank Hsieh agreed to all the items on the list and signed it in March. Ma did not and emailed the group instead. The Taiwan Environmental Protection Union (TEPU) criticized Ma for ignoring important issues and not having the guts to sign the commitments.
