Amid the influences from the pressure identified in the present dynamics of the market, the enterprises are required to get a position, responding to what is being imposed or assumed as a proactive behavior. Under the context of sustainability, this type of behavior is being related to an environmental dimension, under the definition of environmental proactivity. However, there is not a clear approach for the social dimension, which denotes a gap for research, involving explicitly the environmental and social aspects of the actions taken by enterprises, called proactivity of sustainable practices. Furthermore, the idea of proactive behavior can be considered as favorable strategy to introduce sustainability in supply chains. In this sense, this study aims to propose a set of indicators of proactivity of sustainable practices that does not only consider the social dimension. Therefore, the study is characterized as a theoretical study. Hence, it is understood that to move away from a “limited” perspective to the field of environmental dimension, and driving the searchlight of proactivity towards a better alignment to sustainability (while also focusing on the social aspects), it is seen that, through the practices and changes in behavior, enterprises can contribute to a more sustainable development.
