Abstract: A system for determining a carbon footprint includes a graphical user interface (GUI), including a display, a processor, and a memory. The memory includes instructions stored thereon, which, when executed by the processor, cause the system to receive input from the GUI, the input including a travel itinerary inquiry, determine a provider listing based on the received travel itinerary inquiry, display the determined provider listing on the GUI, receive a second input from the GUI, the second input including a listing selection, determine a carbon footprint value based on the listing selection, and display the carbon footprint value and the listing selection on the GUI. The travel itinerary inquiry is at least one of an accommodations inquiry, transportation inquiry, or experiences inquiry.
