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.”...
