1. New environmental data 
To estimate the environmental benefits of repairs, we rely on reference data about the CO2e footprint of common electrical and electronic devices.
For example
We know that an average medium-sized laptop produces around 260 kg of CO2e before it’s ever used. If you help someone repair one of these laptops at an event, we assume that you’ve extended its life by about 50% - and by doing so, you’ve saved the owner from buying a new replacement for that much longer. This equates to about 50% of the total impact of producing a new laptop: around 130 kg of CO2e.
But the data we’ve been using is now getting old. It was first gathered in 2014-15 and products have changed since then. We were also missing high-quality data for quite a few types of product.
By now, you’ve probably heard that we’ve recently completed a big project to update our environmental data. If not, you can read all about it here. In any case, here’s the important bit: we now have much more data on many more types of products than before. This will allow us to make more accurate, product-specific CO2e estimations for most items you see at repair events.
But what about products that we don’t have specific data for…?
