In our survey study, we aimed to explore collecting the basic findings on public risk awareness to product life-cycle of automobile relevant issues such as producing, use and waste. In preliminary survey, we selected 9 risks as the actually public concerned risk in automobile life-cycle. And in subsequent principle survey from 200 respondents in Osaka prefecture who were exposed relatively larger risks in Japan, we investigated risk awareness on each 9 risk, and intention of environment-consciousness behavior. Results showed that, firstly, familiar risks such as “road safety”, “noise and vibration” in use phase were evaluated more important than the unfamiliar risk appeared in producing or waste stage. Secondly, in 5 risks which exposed to general population, including a risk in producing phase, stronger risk awareness lead to stronger intention of environment-consciousness behavior. Our survey study found the respondents' priority of 9 risks and factors for promoting environment consciousness behavior.
