In this paper, the study investigates the behavior of citizens in using information and communication technologies (ICT) in environmental impact assessment (EIA) involvement. Perceived government support, attitude, and perceived behavior control are measured as a predictor model of citizens’ behavior intention. The result reveals that 51 percent of citizens’ intention is well described by the assessment model. The result also reveals the perceived behavior control as a key factor to the involvement intention. This result can be used as a consideration by EIA policy makers and project owner to develop strategies in involving citizens with ICT.
