Conclusion This paper presents an overview of the presence of TBL and sustainability in the relevant literature. Surveying the literature showed an inconsistent usage of sustainability where several studies used the term but were in fact referring to one or two of the three known lines (society, environment, and economy.

Therefore, if the researcher elects to use sustainability in light of the social, environmental, and economic pillars (or lines, the work should explicitly state that.
