Can you cut off the Zoom video please?

If your face is like mine, you will be doing the audience a big service by not letting the video roll on during a Zoom meeting.

But whatever is your face value, you will be doing a service beyond your audience by cutting off the video – and that will be to the environment.

A recent MIT study found that cutting out video during videoconferencing can cut its environmental footprint (that includes CO2 emissions) by 96 blooming percentage points. A 1 hour streaming video on Zoom would result in emissions of over 150 g CO2, finds the study. An audio meeting would have just 4% of the environmental impact, so it is just about 6 g of CO2/hour for a meeting with just audio – which is probably all that’s needed for most virtual meetings. ( )

These data just confirm what most of us intuitively know, that video is far more resource hungry than audio – a HD video requires as much as 20-25 times the bandwidth of a high quality audio. Most of us however would not have correlated bandwidths to environmental footprints, and that’s what this study has done.

When I am about to enter a Zoom meeting, I see that Zoom has highlighted the video option instead of No video option. Just that small shift of the highlight from the first button to the second could make a world of difference – to the world.

Zoom-ers, you listening?

Aren’t folks like Netflix bigger culprits in this context? Perhaps, but let’s start somewhere where it is possible right away – what’s the business case for Netflix without high quality video, anyone?

More such interesting stuff on CO2 and carbon footprint from All about CO2, and that would be over here –
