Abstract

Urban grow in Brazilian Metropolitan Regions have not been happening sustainably. Center-periphery dichotomy characterizes these regions by in which amount of inter-municipal commuters increases due to vast conurbation and dependence between their municipalities. Mainly performed by individual motor vehicles, such displacements contribute to the maintenance of urban sprawl and to rise of carbon dioxide (CO2) emissions in Earth's atmosphere. This paper aims to identify and quantify the CO2 emissions in displacements caused by urban expansion between Goiânia and Senador Canedo. The methodology includes quantitative analysis in different scenarios, i.e. the current situation can be compared with two more favorable scenarios about CO2 emissions, in which there is a transfer of displacements between modes of transport and increase of the occupation factor in the vehicles. The results showed a high CO2 emission in the current situation and a significant reduction of carbon dioxide emissions in the proposed scenarios. The methodology was adequate to record and identify the investigated process. It can contribute to the best understanding and best practices in urban space changes related to the action of different actors who continuously weave the city.
