Your next upgrade could cost you and the planet less

Every year on Earth Day, we talk about the planet. Recycling. Carbon. The choices we make. And every year, one of the biggest culprits sits quietly in your pocket.

Your smartphone.

Not because of how you use it  but because of how it was made.

The carbon cost you never see

Manufacturing a new smartphone produces, on average, 70kg of CO₂. For flagship devices, it's closer to 80–90kg. That's before it's been switched on. Before a single scroll, message, or photo.

To put that in context: it's roughly equivalent to driving 400 miles in a petrol car.

And the problem isn't just one phone. The average UK consumer upgrades every 2–3 years which means the hidden carbon cost of staying connected adds up fast and most of it happens in the supply chain, mining the rare earth materials and assembling the components that go into a brand new device.

Here's the thing though: it doesn't have to be this way.

See your phone's carbon footprint

We built a carbon calculator so you can see exactly what your current device costs the planet and what a smarter upgrade could save.

It takes less than a minute.

What choosing refurbished actually means

When you buy a refurbished phone from Reboxed, you're not getting second best. You're getting a device that's been professionally tested, graded, and restored and one that avoids the need for all that carbon-intensive manufacturing.

The carbon saving on a refurbished device compared to a new one? Up to 70% lower.

That's not a small number. That's the kind of impact that actually moves the needle.

And when you trade in your old device instead of letting it sit in a drawer or worse, go to landfill,  you're keeping it in circulation. Extending its life. Making sure the materials inside it get used, not wasted.

This is what circularity actually looks like in practice

The mission hasn't changed

We started Reboxed because we believed the electronics industry was broken. New for the sake of new. Waste that didn't need to happen. A planet paying the price for a business model built on planned obsolescence.

Recommerce isn't a workaround. It's the answer.

Every device we sell is a new phone that didn't need to be made. Every trade-in is a device that doesn't end up in a drawer or a skip. And every customer who makes that choice is part of proving that a better model works.

This Earth Week  and every week,  that's what we're building.
