Climate literacy is one way to assess youth awareness about current climate change phenomena such as El-Nino or La-Nina. This article aims to build a model of climate change mitigation practices and adaptation among youth in Malaysia, especially in the historical state of Malacca. A total of 400 youth respondents residing in the state of Malacca were selected through a simple random sampling process. Among the sub-constructs studied are sustainable development, environmental conservation, natural resources and effective involvement. The data were analyzed descriptively to pair the reliability of results from Cronbach's alpha with confirmatory factor analysis (CFA). CFA was used to obtain three solutions factor from SPSS 22 and AMOS 20 software. The results showed that the Cronbach's alpha value was at a 'high' classification which surpasses 0.80. Results from CFA analysis shown a three-factor solution is appropriate and acceptable based on the suggested indicators. Therefore, a 30-item measurement model was developed to measure the mitigation and adaptation practices of climate change amongst youth in Malaysia. This study issignificant because few studies have been completed on connecting youth practice and adaptation in regard to climate change it; the current study illustrates how Malaccan youth practice mitigation knowledge in the era of climate change, and how they say they will adapt to the effect of climate change.
