Up to now, urban mobility demand keeps increasing at a great rate and it is satisfied mainly by road transportation mode. Road urban transport, especially private, causes the rise of greenhouse gas concentrations inside cities as a result of increasing commuting. For this reason, local public administrations focus their efforts on more sustainable management of urban transport, both private and public, in order to improve the air quality. The aim of this paper is to assess the greenhouse gas emissions related to urban vehicular traffic in the municipality of Siena (Italy) by way of the Greenhouse Gas Inventory. This methodology is able to quantify greenhouse gas sources and sinks at a local level following the IPCC Guidelines for National Greenhouse Gas Inventories. This powerful tool enhances the knowledge of local administrative authorities in planning and managing a local territorial system. We conducted our analysis with data from the years 1999 and 2000. Starting from the Greenhouse Gas Inventory of the energy sector of Siena, we can quantify the share of responsibility of greenhouse gas emissions related to urban transport; results show that this share is about 41% of the total emissions of Siena. Careful consideration will be given to commuting to work and school, in order to provide valuable suggestions to the policy-makers to enforce a more sustainable management of public and private transport at an urban level.
