Carbon footprint calculator for meetings drawing a world map with origins and destination, carbon per meeting, total carbon and per capita carbon emissions
The carbon emissions based on flying distance between origin and destination cities is always calculated and added even if the person did not fly. Include a logical flag for "flying" in the input data and calculated flying carbon emissions only if T
If none of the participants come from the host city, then it will produce an error. A temporary workaround is to add a line to the input file which includes the host city for a mock participant who does not use any carbon. This will throw off per capita emissions though (by one extra participant who did not actually attend)
