%description
A handy tool to calculate carbon footprints from air travel based on
three-letter International Air Transport Association (IATA) airport codes
or latitude and longitude. footprint first calculates the great-circle
distance between departure and arrival destinations. It then uses the
Department of Environment, Food & Rural Affairs (DEFRA) greenhouse gas
conversion factors for business air travel to estimate the carbon
footprint. These conversion factors consider trip length, flight class
(e.g. economy, business), and emissions metric (e.g. carbon dioxide
equivalent, methane).
