The objectives of this study were.to study environmental damage, natural resource damage, ecological damage, civil liability, criminal liability, administrative liability, and green behaviour levels and to study the independent variables comprising environmental damage, natural resource damage, ecological damage, civil liability, criminal liability, and administrative liability affecting the dependent variable of the green behaviour of undergraduates. The research instrument was the questionnaire, and it was used for data collection from 400 undergraduates. The inferential statistics that were used was the multiple regression analysis. Research results was revealed that the mean scores of environmental damages, natural resource damage, ecological damage, civil liability, criminal liability, administrative liability, and green behaviour levels were at high levels for all aspects. Moreover, it was found that the criminal liability had the most effect towards people’s air quality maintenance behaviour at a rate of 23.6 percent and was statistically significant at the level of 0.01. It was followed by administrative liability with 17.00 percent, which was statistically significant at the level of 0.01. This might indicate that the undergraduates realized to the important of criminal liability to enforces the people’s air quality maintenance. Therefore, in order to control air quality effectively, the criminal liability is needed to use to accomplish the air quality control.
