Videoconferencing

In 2020, there were 468,535 zoom meetings at EPFL!

In 2019, an impact study measured the CO2 emissions of videoconferencing. It was shown that videoconferencing generates much less greenhouse gases than air travel.

As a comparison:

1 hour videoconference at  EPFL

  ->

1.5 kg CO2-eq

(between x1 and x3 depending on the tools)

Lausanne – Zürich (2 ways, by train)

 ->

4.5 kg CO2-eq 

Lausanne – Paris (2 ways, TGV)

->

21 kg CO2-eq 

Lausanne – Paris  (2 ways, by plane)

->

270 kg CO2-eq
