Since it was founded in 2014, Back Market, has been focused on battling electronic waste and extending the lives of electronic devices and appliances. The Conscious project is one way that Back Market addresses a challenging aspect of this mission: to begin meaningful conversations with the public around the environmental impact of high-tech devices and, of course, to begin exploring solutions for them (however imperfect these might be).
Here is everything you might want to know about the project in a few lines—the concept, methodology, and even its limitations.
For your information: the project is now finished and we are currently thinking about giving it a new life. Feel free to tell us what you thought of the widget by commenting this article!
How does it actually work?
Conscious uses the data made available by Electricitymap, an open source project that allows real-time visualization of CO2 emissions from the production and consumption of electricity all around the world. At the moment, data is available for 67 different countries and if it’s not already available, you can contribute by adding your own if your generous heart should move you to do so. Want more details? Here they are.
- Electricitymap pinpoints the general geographic location and forecasts the electricity sources being used at that moment using different factors such as geographic origin, historical data and meteorological conditions.
- These forecasts, carried out on a national scale, are updated every hour and systematically compared to actual data to improve machine learning.
- Research by IPCC (Intergovernmental Panel on Climate Change) is then applied to estimate CO2 emissions (we are able to calculate CO2 emissions associated with the increase or decrease of the electricity demand for the electricity sources that make up an energy mix.)
- From the moment you plug your device, Co2nscious calculates the average carbon emissions in your energy mix (in gCO2eq/kWh) and tells you if these will be lower in the next 6 hours.
- You can also check the current energy mix in real time and the carbon emissions associated with it to decide yourself if you’d like to charge your phone now or later.
- If a user is charging at an optimal time (meaning CO2 emissions are lower in comparison to the average emissions in the next 6 hours), CO2nscious advises users to continue charging their device.
- If the user is charging at a less favorable time, CO2nscious recommends the a better time to charge within the next 6 hours.
And that’s that.
