Methodology

CNaught uses data provided by the International Council on Clean Transportation for 2019 and Transport & Environment to estimate the carbon footprint of your air travel. CNaught uses its carbon calculator methodology for ground transportation to estimate the carbon footprint of your ground travel. For those who flew, we calculate based on a round-trip non-stop flight plus round-trip drive from the airport to the event location. For those who did not fly, we calculate based on a round-trip journey to the event location.
