Rearden Commerce has produced a green-focused personal assistant that provides business travelers and organizations with a “Total Green Travel Experience” when booking travel and related services. The assistant’s functions include a “Carbon Calculator,” hybrid car services and Web and audio conferencing. The tool is designed to help users save time and make green travel choices. The Carbon Calculator shows users “Did You Know” factoids on the amount of emissions produced by the flight they’re booking. The assistant then offers the user a convenient and eco-friendly option of booking an audio or Web conference as an alternative. If the user clicks on the link and takes advantage of the alternative, the calculator shows the number of pounds of carbon dioxide that have been saved from entering the atmosphere.
