Turning off your camera while virtual meeting can reduce carbon footprint: Study

Streaming video in standard definition rather than in high definition by using platforms such as Netflix or Hulu may also offer an 86 per cent drop, according to the researchers.

During a virtual meeting, turning your camera off will do a lot to reduce your carbon footprint, a recent research shows.

The research in the journal Resource, Conservation and Recycling said, you can reduce the carbon footprint of an individual by 96 per cent by turning off your camera in a web call.

“If you just focus on one type of footprint, you miss out on others that can provide a more holistic look at environmental impact,” said researcher Roshanak “Roshi” Nateghi, Professor at Purdue University in the US.

Streaming video in standard definition rather than in high definition by using platforms such as Netflix or Hulu may also offer an 86 per cent drop, according to the researchers.

The team calculated the emissions of fuel, water and land compared with each gigabyte of information used for the study on YouTube, Zoom, Facebook, Instagram, Twitter, TikTok and 12 other networks, as well as video gaming and web surfing.

The more footage used in an application, the bigger the footprints, the researchers said, as predicted.

Before COVID-19 locks, the carbon footprint of the internet had already risen, accounting for around 3.7 per cent of global greenhouse gas emissions.

After the analyses on how internet use affects the ecosystem have generally neglected the water and land footprints of internet technology, the researcher said.

These footprints were studied by the researchers and how they could be influenced by increased internet traffic, discovering that the footprints differ not only from one web site to another.

The team gathered data for Brazil, China, France, Germany, India, Iran, Japan, Mexico, Pakistan, Russia, South Africa, the UK and the US.

Processing and transmitting internet data in the US, the researchers found, has a carbon footprint that is 9 per cent higher than the world median, but water and land footprints that are 45 per cent and 58 per cent lower.

The team obtained data from countries such as Brazil, China, France, Germany, India, Iran, Japan, Mexico, Pakistan, Russia, South Africa, the United Kingdom and the United States.

The researchers find that collecting and distributing internet data in the US has a carbon footprint that is 9% higher than the global average, but water and land footprints are 45% and 58% lower, respectively.
