It’s impossible to imagine a world without mobile phones, but it’s easy to overlook the impact using a smartphone is having on our planet. 

We’ve taken a look at the carbon impact of owning a few different phones over their lifetime.

The carbon footprint of smartphones is broken into two main areas:

  1. Manufacture of the phone
  2. Using and charging the phone

1.  The carbon footprint of manufacturing a phone

There are a few different elements that make up the carbon footprint of manufacturing a handset. We need to consider the materials used (such as rare earth metals), the energy used to run the factory and the transportation of components, packaging and the final products.

Let’s have a look at the carbon impact of different iPhones:

What does this look like over our lifetime?

Based on these values, let’s assume the carbon footprint of the average mobile phone is 70 Kg of CO2.  

The average person in the UK is expected to live to the age of 81, and the average child gets their first phone at the age of 10. So, the average Brit has a phone for 71 years.

Apple assumes that each of their phones will be used for three years so the average Brit uses about 23 phones in their lifetime which equates to 1,610 kg of CO2. That’s equivalent to flying from London to New York 2.5 times.

This doesn’t sound too bad, but we also need to consider what happens once you start using your new iPhone. And remember, there are over 5 billion mobile users worldwide. 

2.  The carbon footprint of using and charging your phone.

Using your phone each day has a bigger impact on the environment than just making it. There’s a lot of energy needed to run the data centres and infrastructure that let you make video calls, post selfies, and stream TV. 

A one minute mobile-to-mobile call produces 57g of CO2, sending a text message (SMS) produces 0.014g of CO2 and using 1GB of data uses 3kg of CO2.

An average user with Honest Mobile generates 315kg of CO2 /year through usage and charging. That’s five times as much as just manufacturing the handset in the first place. As a Carbon Neutral company we offset all of these emissions so your phone is carbon neutral overall. 

To find out more about what we offset as a Carbon Neutral Company, check out our last blog post: Honest Mobile becomes the UK’s first Carbon Neutral Mobile Network

In addition to our Carbon Neutral commitments, we also plant trees for each of our customers to help them offset their personal carbon footprints. If you’re interested in reducing your carbon footprint, here are some simple and easy ways to make a difference.

Apple is Becoming Carbon Neutral too 👍

Apple recently announced its commitment to become 100% carbon neutral by 2030. This means that by 2030 all Apple products sold will have a net-zero climate impact. At Honest Mobile, we’re already proud to be a Carbon Neutral Company so we’re already offsetting the emissions associated with the manufacture of all our customers’ phones. 

An even better option is to consider a refurbished phone. Most of the time, you can’t tell the difference, they’re cheaper, and better for the environment. Here are 5 places we recommend getting a refurbished handset.

What about Android?

Not everyone uses an iPhone, but Samsung and the other big Android manufacturers don’t currently produce device by device analysis of their environmental footprint. However Fairphone produces Android phones which are repairable, have a low impact and they’re also a B Corp, just like us.
