The carbon costs of “digital” are not well understood.
How many emails have you received with “Consider the environment before printing this email” in the signature?
How many have you received with “Consider the environment before hitting Reply All to 26 random people” and adding “Thanks”?
For many people, “virtual” means “not real”.
As in, almost literally, non-existent.
Terms like “cloud” don’t help.
The reality is, the internet is the biggest machine humanity has ever built. It circles the entire planet.
It’s made of hundreds of thousands of miles of cables. Billions of devices.
Switches. Routers. Modems. Phones. Masts. Computers. Fridges. Cars.
(Yeah, you read that right.)
And thousands of data centres that gobble enormous amounts of electricity.
(Data centres also consume huge quantities of water, as does the rest of the tech sector. But let’s just stick with energy consumption for now, to keep things simple.)
Many of these devices, and a lot of this infrastructure, are still powered by electricity generated by burning fossil fuels. That has a knock-on effect in the amount of CO2 we release into the atmosphere.
(A short, text-only tweet results in the release of about 0.2g of carbon.)
Our contribution to the overall effect of this is minuscule. But so is almost every organisation’s, taken individually.
Our web services are hosted on Azure, which claims to be carbon neutral. But much of that is through offsetting, and it’s not clear how effective that is.
So, we’re committed to reducing the carbon impact of all our sites as much as we possibly can.
Even if we can get them powered by 100% renewables, this will help, because it will free up energy to heat people’s homes. Which, let’s be honest, is somewhat more important than running our website.
Any designer will tell you that the first step to a solution to *any* problem is to understand the problem. So we’ve started to gather data. And, as ever, we want to #DesignInTheOpen
So we’ve created a dashboard to illustrate the CO2 our most popular web services create. This is pretty much realtime data. Mobile-friendly version follows. Now we can set targets to reduce it.
Graphs are all to the same scale. The comparisons are direct. As we improve things, I’ll update CO2/pv values.
