64TEQ Tools Carbon cost of a refresh

Carbon cost of a refresh · free, runs in your browser

Put a carbon number on the next device refresh.

Most of a laptop's lifetime carbon is emitted before anyone switches it on, which is why keeping kit longer and reusing it matters more than any power setting. Count the devices in the refresh and you get the numbers for the ESG report, with the assumptions next to them and the manufacturers' own figures available on request.

Carbon cost of a refresh

What does replacing the laptops cost in carbon, and what does a year longer save?

Count the devices you are about to replace and we show the carbon built into making them, what running them costs each year on the UK grid and what you save by keeping them a year or two longer. Numbers you can put in an ESG report, with the assumptions next to them.

Manufacturers publish a carbon footprint for every model (Dell, HP, Lenovo and Apple all do). We use rounded planning figures by device type; if you want the exact model, ask and we pull the sheet. Most of a laptop's lifetime carbon is emitted before you switch it on, which is why keeping kit longer and reusing it matters more than any energy setting. Runs in your browser.

Servers means physical servers, not virtual machines. Extend by 0 to see the refresh alone.

The carbon built into the new kit, the yearly running carbon, what a longer cycle saves and what reuse is worth appear here, with the planning figures behind each.

How it works

Four steps, no account.

Count the devices

Laptops, desktops, monitors, physical servers, phones and tablets. Set your current cycle and how many years you are considering extending it by.

See the carbon

The carbon built into the new kit, the yearly running carbon on the UK grid and what a longer cycle saves per refresh.

Decide what happens to the old kit

Resale or reuse displaces a new device being made somewhere else; recycling recovers materials but not carbon; a cupboard does neither.

Get the model figures

Send us the models and we return the manufacturers' published figures with sources, and a certified route for wiping and reselling the old kit.

Straight answers

Questions about this tool.

Where do the figures come from?
Rounded planning figures by device type, taken from the product carbon footprints that Dell, HP, Lenovo and Apple publish for their current business models, with UK grid electricity at about 0.2 kg CO2e per kWh. The exact figure for your model is in the maker's sheet and we can supply it.
Why is extending the cycle such a big saving?
Because a five-year cycle buys a fifth fewer devices than a four-year one over time, and roughly 80 per cent of a laptop's carbon is in making it. The cost is more support tickets and, on Windows machines, checking they can still run a supported version.
Does older kit not use more power?
For laptops and monitors the difference is small enough to ignore in planning. For servers it is not: electricity dominates a server's footprint and a newer, more efficient box can pay back in carbon as well as cash.
What does 64TEQ do with the old kit?
Certified data wiping, then resale or reuse where the device has life left and recycling where it does not, with the paperwork your auditor wants. Reuse is the better outcome for the planet and for your budget.
Can I use these numbers in our ESG report?
As planning figures with the assumptions stated, yes. For the report itself use the model-level figures from the manufacturers, which we can pull together for you with sources.
