Turn off camera during online chats to cut emissions: Turning off the camera throughout a one hour virtual meeting may reduce 25 times the carbon footprint of a call as opposed to when the camera is turned on.

That’s one of the conclusions of recent research produced in the journal Resources, Conservation and Recycling, that believes a 1 hour video conference with video on, produces 157.3 grams of CO2, which is a lot more from the projected 6.2 grams made from a call without an initiated video camera.

Cameras yield carbon

The study believes if a user has about 15 one hour meetings each week, their carbon footprint every month may account for 9.4 kilograms of CO2.

Monthly emissions can be lowered to 377 grams of carbon dioxide by easily shutting off the video.

The study suggests if 1 million videoconference users were to make that change to meetings without using a camera, they will save over 9,000 tonnes of carbon dioxide. This is equal to powering a city of 36,000 people for a month by means of coal fired stations.

Save water as well

The authors of the research realise that turning off the video throughout conference calls could also save 10.7 million litres of water per 100,000 users each month. This is the suggested amount required to make about 53.5 tonnes of tomatoes.

By restricting conference calls to only voice, there could also be a 239,000 square-metre preserving of land, nearly the extent of St. James Park in London, as reported by the study.

If you need to, use SD

The study also believes one hour video streaming in HD emits nearly 441 grams of CO2, as compared to only 62.94 grams if streaming is done in standard definition.

The study, which is backed by the Purdue Climate Change Research Centre, the Purdue Centre for Environment, the Yale MacMillan Centre’s Council & the MIT Energy Initiative  suggests if 70 million streaming consumers were to reduce the video status of their streaming services, there could be a monthly decline in 3.5 million tonnes of CO2.

WFH May cause emissions to soar

The study also predicts the worldwide carbon footprint may spike by 34.3 million tonnes of carbon dioxide if remote work goes on up to the end of 2021.

That rise in carbon emissions will need a forest twice the area of Portugal to isolate all the emitted carbon dioxide.
