In-person vs virtual meeting CO2 API

Compare CO2e of an in-person meeting (attendees x round-trip travel km x mode factor; flight 0.18, car 0.171, rail 0.041 kg/km) against a virtual meeting (attendees x hours x 0.15 kWh x grid intensity). Returns in-person and virtual kg CO2e, kg saved by going virtual, reduction percent and tree equivalents.
