Reducing Greenhouse Gas Emissions of the Transport Sector in Urban Areas: Assessing Possible Actions Through Specific Performance Indicators

The transport sector is responsible for more than a quarter of the total Greenhouse Gas (GHG) emissions. Several actions can be implemented to reduce them, especially in the urban areas. For this reason, to facilitate the selection of the actions to be implemented, a literature review was carried out to provide a list of actions that the different stakeholders can adopt. Moreover, to facilitate their assessment, a set of Performance Indicators (PIs) was formalized, exploring their impacts on four sectors, including environmental, energy, social, and economic. Finally, considering the pivotal role of local public transport in reducing GHG emissions in urban areas, an example of the actions implemented by Gruppo Trasporti Torinese, which is the local public transport company of Turin is presented.
