This post was updated on Sept 7 2021 to include the video of our webinar on this topic.

Every device we buy comes with a hidden environmental cost. Understanding this hidden cost is crucial to learning just how green repair is, so we’ve been on a mission to reveal the true environmental impact of the products we buy.

We first investigated this issue back in 2014 and used the data we found to power the Fixometer – our tool that helps community repair groups estimate the environmental impact of repairs made at their events. A lot has changed in the last 7 years, so the time has come to update and expand this data.

The data that many companies refuse to share

After putting a call out to our community, a handful of brave volunteers came together to drive the investigation. Together, we scoured the internet for data that could tell us about the carbon impacts of the products we see at community repair events, such as laptops or toasters.

We soon found that the best sources for this information were lifecycle assessment (LCA) reports. Manufacturers, academics and consultancy firms use these reports to measure the environmental impacts of products. We were most interested in how much greenhouse gas is produced at each stage of a product’s life, measured as CO2 equivalent (CO2e).

Finding these LCA reports isn’t easy. Many manufacturers simply don’t produce them. Some do, but only a small number actually make them available to the public. We found that:

  • Only a small number of tech companies share data for some types of IT products, such as laptops, desktops and monitors. (Most of these companies seemingly publish this data to get environmental accreditation, such as EPEAT ecolabels.)
  • For most household electrical/electronic devices, there is very little publicly available data about environmental impacts, especially during the manufacturing phase. Much of the data we did find came from academic journals.

We even asked some manufacturers to share this data – they didn’t help us. Most played dumb or ignored us completely.

As a result, we couldn’t find more than a few examples for nearly half of the product categories we explored.

Ultimately, almost every manufacturer we looked at talked proudly about corporate sustainability on their company website.

But we need companies to put their data where their mouth is, otherwise they are simply greenwashing.

What did we learn?

Despite these challenges, we analysed data on nearly 500 products across a wide range of product categories. And here’s the headline:

For most types of item we see at community repair events, most of the global warming impact occurred before it was used for the first time.

That’s because for many products, extracting raw materials and manufacturing are very carbon intensive processes. You can learn more about this with our interactive ‘Materials Matter’ activities.

Here’s how some of the common items we see at repair events stack up:

Product CategoryPre-use CO2e impact as percentage of total
Computer monitor55%
Desktop computer53%
Vacuum cleaner32%

But let’s dig a bit deeper. The most common devices we see at repair events are medium-sized laptops. So, we looked at 64 models of medium-sized laptop from Apple, Dell, HP, Lenovo and Microsoft. We found that an average laptop of this size represents about 263 kg of embodied CO2e. That’s the equivalent of a flight from London to Rome and around 81% of the total CO2e each device produces over its entire life. For most of these laptops, the manufacturer assumed a lifespan of just 4 years.

Here’s how the hidden environmental cost of a laptop builds up over such a short lifespan:

The impact of replacing a device so often is clear. When products aren’t designed to last or be repaired, manufacturers’ emissions increase. So what can we do about it?

Reducing our consumption

As consumers, the main way we can reduce the hidden environmental cost of our devices is to keep using them for as long as possible. By extending the life of our gadgets and fixing them when they break, we can slow down the stream of newly manufactured devices.

Here’s what happens if we extend the life of a laptop by 50% or 100%:

The longer we can use a device, the lower the CO2e impact will be over time.

We can’t do this alone, and we can’t rely on companies

But manufacturers keep making repair more and more difficult. So to reduce the hidden environmental cost of our devices, we also need to change the system that generates so much CO2e while producing short-lived, unrepairable products. We need manufacturers to clean up production and remove barriers to repair. And given we can’t rely on companies to do this voluntarily, we need a real Right to Repair.

We ran a webinar with Jessika Richter from The International Institute for Industrial Environmental Economics in Lund in September 2021 where we explored this work in more detail. You can watch it below:

What now?

Next we’ll use what we’ve learned to update our Fixometer tool. The data we’ve found will help us improve the reliability and accuracy of future calculations, allowing community repair groups around the world to better understand their impact. We’ll also be able to add calculations for new categories of products, including non-electrical items for the first time.

We have published our data here under a Creative Commons license (CC BY-SA 4.0).

And in the meantime, we’ll continue to push for products to be made more repairable.
