Package: footprint Title: Calculate Air Travel Emissions Version: 0.2 Authors@R: c(person(given = "Anthony", family = "Schmidt", role = c("aut", "cre"), email = "aschmi11@utk.edu", comment = c(ORCID = "0000-0003-4478-0638")), person(given = "Kasia", family = "Kulma", role = "aut", email = "katarzyna.kulma@gmail.com")) 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).
