The transmission and viewing of online videos generates 300 million tonnes of carbon dioxide a year, or nearly 1 per cent of global emissions. On-demand video services such as Netflix account for a third of this, with online pornographic videos generating another third.
This means the watching of pornographic videos generates as much CO2 per year as is emitted by countries such as Belgium, Bangladesh and Nigeria.
That’s the conclusion of a French think tank called The Shift Project. Earlier this year, it estimated that digital technologies produce 4 per cent of greenhouse gas emissions and that this figure could soar to 8 per cent by 2025.
Now it has estimated the CO2 emissions due to online videos alone. The report’s authors used 2018 reports by companies Cisco and Sandvine to work out global video internet traffic. They then estimated how much electricity was used to carry this video data and view it on different devices, from phones to TVs.
Finally, they estimated the overall emissions using global average figures for carbon emissions from electricity generation.
