This study aims to comprehend Portland State University (PSU)’s green campus strategies, and students’ level of knowledge and living practices relating to green campus. PSU’s sustainable campus plan has been nationally and internationally recognized. A literature review, field investigation, and interviews were conducted to ascertain the PSU green campus strategies. This study also used a survey to understand students’ level of knowledge and practices. The survey results were analyzed by SPSS. Green campus projects at PSU were operated by official organizations and funded according to PSU’s long term plans in 12 multilateral categories: administration, energy, water, climate action, green buildings, green purchasing, waste reduction and recycling, food and dining services, transportation, land use, action, and education and student activity. The survey results show that the level of students’ understanding about PSU’s green campus strategies was somewhat low, but the amount of practice of a sustainable lifestyle was higher. Students who had taken courses related with sustainability or were engaged in sustainable activities had more knowledge about green campus strategies than students who had not. Therefore, it would be important to focus more on educating students and developing related programs in order to have more positive effects of green campus projects.
