‘Green’ is the trendy word that people pay attention to it. Green ICT is currently highlighted to be an important strategic technology due to its various benefits in terms of reducing greenhouse gas emissions, lowering electricity costs, nurturing corporate images, etc. However, the adoption of green ICT products or services is not prevalent, especially in developing countries. Green consumers, particularly young people, are the key to build the success of the green ICT adoption. Thus, applying the case of university freshmen in Thailand, research objectives are to examine the understanding of youths about the green ICT, to explore the awareness and the acceptance of youths on green ICT practices, to discover the causes of adoption or refusal, and to introduce a systematic guideline for effectively promoting green ICT products or services. The research results could increase the use of green ICT in young people.
