Note 1: to account for the impact of virtual visits, it is assumed that each attendee takes part in a 3-hour virtual meeting. The emission factor used is for 1 hour of laptop electricity use.
Note 2: for air travel, the emission factor used is dependent on the distance entered. If the distance entered is greater than, or equal to, 7,400 km, the emission factor for a long-haul flight is used. If the distance is less than 7,400 km, the short-haul flight emission factor is used. As defined by the DEFRA emissions factors-
Data available:
Example in which there are 5 management meetings with 15 attendees visiting per meeting, with 25% virtual, and 75% in person:
((25% x 3 x 0.014 kg CO2 eq per hour) + (75% x 6000 x 0.293 kg CO2 eq)

Note 1: to account for an impact of virtual visits, it is assumed that each monitor attends a 3-hour virtual meeting. The emission factor used is for 1 hour of laptop electricity use.
Note 2: for air travel, the emission factor used is dependent on the distance entered. If the distance entered is greater than, or equal to, 7,400 km, the emission factor for a long-haul flight is used. If the distance is less than 7,400 km, the short-haul flight emission factor is used.
