According to Indonesian index of environmental quality in 2014, Jakarta’s environmental quality is the poorest among Indonesian 33 provinces. This environmental problem of Jakarta is caused by the behaviour of the citizens that is not environment-oriented. To resolve the environmental conditions of Jakarta, the government, as well as society, need to work together toward the improvement of environmental quality by encouraging everyone to adopt pro-environmental behaviour (PEB). One of the factors that contribute to the configuration of pro-environmental behaviour is New Ecological Paradigm (NEP). Therefore, this study aims to test the contribution of NEP on PEB. The respondents of this research are 332 of Jakarta’s citizens aged 21-65 years. Two scales are used in this research, namely General Ecological Behavior Scale (GEB) to measure PEB, and New Ecological Paradigm Scale (NEP) to identify respondent’s NEP. Results indicate that NEP predicted PEB in about 2,7%. NEP is an individual belief about the environment that causes the individuals realise the consequences that they would gain from their behaviour toward the environment. Furthermore, this belief contributes to the emergence of pro-environmental behaviour. Hence, the higher NEP of a person, the more he adopts PEB.
