Chinese government puts forward a concept: five in one, putting environment in the same significant position as economy, politics, society and culture, which highlights the significance of environment. With the continuous increase of environmental awareness, many scholars pay more attention to green finance. However, the researches based on economic or social aspects, mostly stay on the theoretical level without studying how much people know about this concept. This paper, however, based on the questionnaire on Guangdong Undergraduates, aims to know about the deviation between undergraduates’ awareness of the importance of green finance and the real situation. The results turn out that there are significant deviations in the following areas: concept, methods, reasons, purpose and representative principles, etc. Based on the results, the author tries to explain the reason of the existence of these deviations and the connection of enhancing education of environmental protection.
