<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">TRX Travel Analytics developed its calculator in 2006. The website provides in-depth information about the data sources and metrics used for the calculator. For this and the following reasons, the authors rated the quality of the TRX Travel Analytics calculator as very high. It is the best of the three evaluated calculators and is likely the best currently available air travel CO2 emissions calculator:</FONT></SPAN></P>

<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">• The calculator is based on extensive data sets and accounts for the largest number of parameters.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">• Data sets are updated regularly.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Calibri">• Because the calculator distinguishes between different carriers, it enables travelers to choose the most efficient carrier ahead of time.</FONT></SPAN></P>
