Comprehensive assessment of the carbon neutrality actions from the automotive sector

The aim of this paper is to analyse and demonstrate the carbon neutrality actions of a special facility in the context of the automotive sector. In order to analyse the emissions, a carbon simulation model is developed. Offsetting options are also overviewed in a systematic way. We provide a methodology for a systematic analysis of greenhouse gas (GHG) emissions and offsetting opportunities of an automotive facility. We compile an inventory of the carbon emissions, identify offsetting options and prepare a cost–benefit analysis of the mitigation actions. The relevance of United Nations Sustainable Development Goals (SDGs) is also assessed. We examine the GHG emissions of an automotive proving ground, ZalaZone in Zalaegerszeg, Hungary, as a case study. Four scenarios with various shares of decarbonisation options have been proposed to achieve the vision of net zero GHG emissions. It was found that net zero emission is achievable. The CBA concluded that the net present value is negative; however, there are significant external benefits. It was revealed that the operation of the facility contributes to multiple SDGs and provides different pathways to carbon neutrality.
