Sustainability especially targets the process of reconciliation and balance among specific tendencies occurring in its economic, human, and environmental dimensions. This study intends to reveal if salient differences between the levels of each dimension are present across a punctual national context, i.e. the Romanian one, in the 2006-2020 period. It also intends to investigate the effects of economic and social sectors on the main weak points of environmental wellbeing, if these are still significant and negative or, contrary, if sustainable path could be found in these links in the same circumstances of analysis. In this way, we centered our debate on environmental performance, found its main vulnerabilities for observing, on one hand, if Romania follows different environmental paths comparatively with the other two dimensions of wellbeing and, on the other hand, the nature of the effects of society's performance (with its economic and social parts) upon it. Particularly, our study aims to respond to a practical need of research in this country, being also possible to represent a support for the policies addressing sustainable development in the Romanian context. Based on descriptive and path analyses, our results showed that, in the case of environmental wellbeing, the most vulnerable indicators are shown to be the ones regarding renewable energy and energy savings. The main susceptibilities in Romania seemed to be in respect to the relationship between (1) energy savings and safe sanitation, healthy life, population growth, public debt, employment and (2) renewable energy and healthy life, population growth, public debt. Accordingly, the two most sensitive environmental indicators were shown to be affected by these human and economic components of wellbeing, recommendations being formulated in the directions of more careful strategical actions for their improvement in such a way of not highly contributing to the degradation of the environment.
