Towards a Green Transition: Preliminary Steps of a Quantitative Model.

Recently, environmental sustainability has been tackled several times due to the impending climate change the earth is facing. Numerous techniques have been applied to reverse the direction companies were going into. In this paper, it is explained the importance that Lean Manufacturing tools and Industry 4.0 technologies can have on the sustainable side of a company. The aim of this work is to fill the scientific gap related to studies deepening the combination of these different paradigms, Industry 4.0-Lean-Green, which have been scarcely investigated together and proposing the preliminary results of a quantitative model that helps towards a green transition. Thus, a Systematic Literature Review has been performed to detect which were the key variables of these three fields and then, it was studied what their interaction was. Then through mean of pair wise comparison matrices the first steps of the quantitative models are shown that investigate the relationship amongst the key variables identifies showing also transitivity relationship. This study is giving the opportunity to understand the main variables of Industry 4.0 and Lean manufacturing on which companies have to act in order to have an impact on green variables and their overall environmental sustainability.
