Device
We include a one-off emission for the production and transport of your device. In fact, smartphones are manufactured from various rare earth metals such as gold, silver, cobal and lithium among many others. In doing so, we assume – on the basis of published environmental reports of manufacturers such as Apple, Huawei and Fairphone – a life span of three years for smartphones and wearables
Telecom use
To calculate your telecom usage, the algorithm takes into account your real-time consumption (calls, texts, data)
Battery consumption
The calculator measures the charging time of your smartphone and then calculates the CO2 emissions released in that process
Onboarding and Activation
Ordering your UNDO SIM card on internet or with the app, including activation of it also has its own footprint. The UNDO app takes into account this as a one off emission to make sure nothing is missed along way
