Emissions of greenhouse gases: Brazilian air transportation sector

Brazil will host the FIFA World Cup in 2014 and the summer Olympic Games in 2016 within the context of sustainable games, already established by the Summer Olympic Games in London, 2012. Thus, it is necessary further studies on the environmental impacts of the sectors related to these events. One of the main sectors is transport. The transportation sector is the biggest consumer of liquid fuels, with more than 50% of world consumption and it uses almost 20% of the world’s total delivered energy. Given the continental dimensions of Brazil, much of the transportation will be through civil aviation. Thus, this study aims to account for current emissions of carbon dioxide (a greenhouse gas) of the top airlines operating in the Brazilian domestic and international markets to create a characterisation factor of the sector in order to propose mitigation actions of these emissions. It will be used the methodology developed by the Intergovernmental Panel on Climate Change, using the following data: number and type of aircraft, length and number of flight stage.
