Air pollution and greenhouse gas emissions are one of the main problems impacting on climate change and society, resulting in issues for the environment and human health. These effects are mainly induced by transportation; indeed, most cars still use gasoline or diesel fuelled engines, which present several negative externalities such as emissions, pollution, noise, and fuel dependence. To reduce these impacts, many European countries have developed plans based on the circular economy paradigm and the electrification of cars to achieve the zero-greenhouse gas emission goal by 2050. However, this transition is complex due to several factors such as automotive supply chain re-design, impacts on employment, technological changes, mobility behaviours, and infrastructure development, especially in Italy, where the interdependence between electromobility and electricity production and distribution are slowing down this transition. Therefore, the purpose of this paper is to develop a system dynamics framework able to model the effects of the circular transition on automotive supply chains, by modelling production, re-manufacturing, and recycling activities for three different types of vehicles i.e., fuel, hybrid, and electric. Preliminary results of the model demonstrate that the circular transition of the automotive sector can bring to benefits in terms of reduction in raw material consumption and increasing in recycling rates.

Abstract
Air pollution and greenhouse gas emissions are one of the main problems impacting on climate change and society, resulting in issues for the environment and human health. These effects are mainly induced by transportation; indeed, most cars still use gasoline or diesel fuelled engines, which present several negative externalities such as emissions, pollution, noise, and fuel dependence. To reduce these impacts, many European countries have developed plans based on the circular economy paradigm and the electrification of cars to achieve the zero-greenhouse gas emission goal by 2050. However, this transition is complex due to several factors such as automotive supply chain re-design, impacts on employment, technological changes, mobility behaviours, and infrastructure development, especially in Italy, where the interdependence between electromobility and electricity production and distribution are slowing down this transition. Therefore, the purpose of this paper is to develop a system dynamics framework able to model the effects of the circular transition on automotive supply chains, by modelling production, re-manufacturing, and recycling activities for three different types of vehicles i.e., fuel, hybrid, and electric. Preliminary results of the model demonstrate that the circular transition of the automotive sector can bring to benefits in terms of reduction in raw material consumption and increasing in recycling rates.
