emissions studies is that they were carried out based upon time series data. The Divisiaapproach has severe restrictions in some applications with cross-sectional or panel data,there is no apparent way of sequencing the observations (Good et al., 1999). Timilsinaand Shrestha (2009) provide a concise review of this literature. To date no studies havebeen done to analyze CO 2 emissions at individual levels. This study attempts to add newempirical evidence to both the literature of mode of transport to work and vehicleemissions.3 Data DescriptionFor the purpose of the study, a questionnaire 11 has been designed to conduct a householddrop-off survey. Since survey is targeting only the working population and our channel ofdata comes mainly from two working zones which are Ebene and Port Louis.Congestions are usually lousy in close proximity to those regions. The survey started inDecember 2009 and was completed in February 2010. About 87% of the whole 600questionnaires were received. Due to the incompleteness and bias of some questionnaires,20 observations were discarded of the 521 received which led us to 501 observations.About 28% and 56% individuals in our sample travel by car and bus respectively. As forthe remaining 16%, it portrays individuals who commute to work by motorcycle, on foot,by company van/car and by taxi. However, the big majority in the third group travels towork by motor cycle.The questionnaire has four parts. Section 1 was meant to gather information about thedemographic characteristics of the individuals and their views about the transport11 The questionnaire is available upon request.Risø International Energy Conference 2011 Proceedings Page 390
