Stephen Moss: Pointless emails: they’re not just irritating – they have a massive carbon footprint

A new study commissioned by energy company OVO reckons Brits send more than 64m unnecessary emails every day, and that if every adult in the UK sent one fewer “thank you” email a day we would save more than 16,433 tonnes of carbon a year – equivalent to 81,152 flights to Madrid or taking 3,334 diesel cars off the road

These are the sorts of stats beloved of green energy companies trying to get a bit of free publicity. But it’s all true, according to Mike Berners-Lee, a professor in the environment centre at Lancaster University, author of How Bad are Bananas: The Carbon Footprint of Everything, and brother of Tim Berners-Lee, inventor of the web. True in very general terms anyway: he probably won’t vouch for all those flights.


How can one little email destroy the planet, I ask Mike Berners-Lee, who advised OVO on the research. “When you are typing, your computer is using electricity,” he says. “When you press send it goes through the network, and it takes electricity to run the network. And it’s going to end up being stored on the cloud somewhere, and those data centres use a lot of electricity. We don’t think about it because we can’t see the smoke coming out of our computers, but the carbon footprint of IT is huge and growing.”...
