Back Market is the leading European marketplace of refurbished smartphones. Our company has always committed to extending the life of electronic devices to fight against e-waste. The European Union exports 13.1KG of e-waste per person every year according to an Environmental Audit Committee report. Each year, Back Market offers thousands of smartphones a second life through refurbishment, using fewer natural resources. However, phones’ environmental impact is not limited to manufacturing; it is also a matter of how we use them. According to research (Digital Power Group, 2019), using a smartphone can consume up to as much energy as a refrigerator. With 3.8 billion smartphones currently in circulation, it significantly contributes to the global energy consumption and CO2 emissions. To highlight our brand values, we decided to act and propose a solution.

Describe the strategy

The challenge for us was to prove that our commitment to care about the environment while selling smartphones was real. As we already tell customers how much CO2 they are saving when they buy a refurbished smartphone on our website, we had to go one step further. While people know that a smartphone’s hardware has an environmental impact, not all of them realize that this impact continues every time they charge it. In 2007, the carbon footprint of the mobile phone industry represented 1% of the global carbon footprint; by 2040 it will exceed 14%. By creating a solution that can be accessed by most smartphone users on the planet, we proved our commitment of a sustainable approach to the smartphone industry. Instead of alarming facts, we preferred a pragmatic solution through data to empower all smartphone users that want to take action against CO2 emissions on a daily basis.

Describe the execution

CO2NCIOUS is a free mobile app available on Google Play Store, compatible on 80.9% of smartphones. It uses: - your localization data - energy providers datasets (to know the mix of energy sources powering your location) - environmental datasets (to know the CO2 emissions level per kilowatt-hours associated to your mix) - your phone battery level (to know how long you can wait before repowering your battery) - and a predictive machine learning algorithm, CO2NCIOUS shows what energy sources are powering your battery, the CO2 emissions level of you charge, and when to charge it in the upcoming 12 hours to trigger fewer CO2 emissions by using more renewable sources. Our tool was preinstalled on all compatible refurbished smartphones sold on our website. Our source code was published on open source platforms and sent to major smartphone manufacturers like Apple and Samsung to integrate it as a future preinstalled feature.
