How much CO2 does making a smartphone produce?

According to GSMA data, the sale of over 1.2 billion new smartphones in 2024 generated more than 60 million tonnes of CO2 emissions from manufacturing alone — before a single device was ever switched on.

Is recycling my old phone at a store enough?

Traditional recycling recovers materials, but only 22.3% of e-waste is formally recycled. Reusing your device — keeping it running longer — has a far greater impact than handing it in for recycling.

Does using a refurbished or repurposed device really make a difference?

Yes. GSMA research shows refurbished devices generate 80–90% fewer emissions compared to manufacturing a new one. Repurposing your old device as a dedicated display or dashboard is an equally impactful alternative.

The Hidden Carbon Cost of Your New Smartphone (And What You Can Do About It)

Here’s a number that might make you pause before your next upgrade: over 60 million tonnes of CO₂.

It’s easy to think of environmental impact as something that happens later — in a landfill, decades from now. But with smartphones, the heaviest toll comes first.

The Moment of Manufacturing Is the Moment of Impact

When you buy a new phone, you’re not just purchasing a device. You’re funding a manufacturing process that spans rare earth mining in Central Africa, chip fabrication in Taiwan, battery assembly in China, and global shipping to your front door.

The assembly plants run 24/7. The copper, gold, cobalt, and lithium must be extracted from the earth. Each step generates emissions. And unlike the electricity you use to charge your phone (which can theoretically come from renewables), the manufacturing emissions are largely locked in at the moment of production.

The Drawer Problem: 5–10 Billion Devices Sitting Idle

Here’s what makes this especially frustrating: the world already has enough smartphones to meet most of its needs.

GSMA estimates that between 5 and 10 billion mobile devices are sitting dormant in household drawers worldwide — retired from daily use but not yet disposed of. They still work. They still have value. But they’re doing nothing.

Every new phone that’s manufactured to replace a perfectly functional old one adds to that 60-million-tonne figure without any real necessity.

What Does “Repurposing” Actually Save?

The math here is encouraging. GSMA research shows that refurbished or repurposed devices generate 80–90% fewer emissions compared to manufacturing a brand-new equivalent. (Source: GSMA Mobile Net Zero 2026)

That means if you keep your old iPhone or Android device running for three more years — as a secondary clock, a kitchen display, a bedside dashboard — rather than discarding it and buying new, you’re preventing the equivalent of several hundred kilograms of CO₂ from entering the atmosphere.

That’s not symbolic. That’s a real, measurable difference.

The Scale of What We’re Leaving Behind

The UN Global E-waste Monitor 2024, published by the International Telecommunication Union (ITU) and UNITAR, reported that the world generated 62 million tonnes of e-waste in 2022. Only 22.3% of that was formally recycled. (Source: UN Global E-waste Monitor 2024, ITU + UNITAR)

The rest? Landfilled, incinerated, or informally processed in ways that release toxic chemicals and lose an estimated US$62 billion worth of recoverable materials — gold, copper, rare earth elements — every single year.

The problem isn’t that people don’t care. It’s that “recycling” is presented as the responsible option, while “keeping using it” isn’t marketed to anyone.

Small Actions, Real Numbers

You don’t need to make dramatic lifestyle changes. But you do need to make deliberate ones.

Keep it running. The single most effective thing you can do is delay your next upgrade. Each year you extend the life of your current device, you defer the emissions of manufacturing its replacement.

Repurpose instead of retire. When your old phone is no longer your daily driver, it doesn’t have to become e-waste. Old smartphones are fully capable of running as dedicated home displays, bedside clocks, kitchen timers, or digital dashboards — without installing a single app.

Think before you recycle. Formal recycling programs are better than landfill, but they’re not the finish line. Reuse comes before recycling in every environmental hierarchy for a reason.

The next time you feel the pull of a new phone launch, it’s worth pausing to ask: what will actually happen to my current one? And what would it cost the planet if it ends up in a drawer?
