This paper examined the level of Environmental Civic Actions (ECA) using a modified version of the Environmental Action Scale (EAS) and Place Attachment Theory (PAT). The Environmental Action Scale measured the level of participation that would have a collective impact on environmental issues. The data was obtained "via" online questionnaire from 230 young and middle-aged citizens living in Nigeria. 152(66%) males and 75(33%) females indicated their gender, and most participants identified as under­graduate students (n = 179). SPSS statistical software package was used for factor analysis to ascertain if measure items were suitable for the study context using principal component analysis (extraction method) and Kaiser Normalization rotation method. Some findings revealed that the majority of participants have a high level of pro-environmental intention and low levels of actual environmental civic behav­iors. In addition, most participants never participated, organized a protest, or boycotted a company engaging in negative environ­mental behaviors. Furthermore, place attachment, and fear of punishment in form of fines, and levies influenced the intention to engage in positive environmental behavior. The study contrib­utes to the dearth of knowledge on environmental civic actions in a developing country and provides specific insights that are beneficial to policymakers, researchers, and stakeholders.
