Mobile Phone E-Waste Index
e-waste, noun /ˈiːweɪst/: discarded electrical and electronic kit – especially mobiles, computers and other devices – that often contains hazardous materials and needs specialist handling to recycle safely.
At Envirofone we help millions of people give their tech a second life, so we know how many phones end up languishing in drawers. This page summarises findings from an external study across 27 countries that spotlights the value of unused mobiles and the environmental benefits of recycling or repurposing them.
This first-of-its-kind analysis compares mobile phone e-waste country by country. It reveals how many devices are in use and how many sit unused – in some places there are more shelved phones than people. Using the EU framework for e-waste calculations alongside survey data, the study estimates the current mobile phone e-waste picture in all 27 locations.
We first calculated the number of mobiles in each country – both active handsets and those that have been shelved, meaning they are no longer used but haven't been recycled or discarded. We looked at the share of second-hand models in daily use and the total volume of idle devices that could be resold or recycled.
We then examined how people dispose of phones: the proportion gifted or sold on, the e-waste created when devices are thrown away incorrectly, and the recycling and reuse rate through municipal schemes or retailer take-back programmes.
The analysis also models potential environmental savings if every shelved phone were processed responsibly. That includes avoided CO2 emissions from manufacturing equivalent handsets, the kilos of lead, arsenic and mercury kept out of soil, and the recoverable value of precious metals such as gold, platinum, palladium and copper. Finally, we include each country's overall municipal recycling rate to gauge wider waste habits.

* Data sourced from the household survey.
The Mobile Phone E-Waste Index compares the estimated total number of mobile phones across 27 countries – both active devices and those tucked away. Throughout, “shelved” refers to handsets that are out of use but have not left the home.
The index covers 24 European nations plus the USA, Canada and New Zealand for a global benchmark. The study used consistent, publicly available datasets for each country alongside findings from a bespoke household survey.
Envirofone did not commission this research; we are sharing the independent findings to highlight the scale of unused devices and the potential impact of recycling or reuse.
The data columns in the index are:
By default, the index ranks countries by shelved mobiles per capita from highest to lowest. The methodology for each data point is outlined below.
To estimate the number of phones in each market, including unused stock that remains in homes, the study applied the “Waste over time” model from E-Waste statistics - guidelines on classification reporting and indicators by Van Straalen et al. This uses European import, export and manufacturing data to assess the number of phones placed on the market, then applies product lifetimes to model both end-of-life disposal and the remaining stock of devices.
The outputs were combined with responses from a tailored household survey that asked about used and shelved phones.

The total number of phones currently being used per inhabitant. A weighted average draws on the number of mobile contracts per capita, the stock of smartphones per person multiplied by the share of shelved phones from the survey (for EU members), and the survey's own estimate of phones in use.

The proportion of handsets in use that were bought or received second-hand. The figure is modelled from the household survey and reflects the share of used smartphones in households.

The number of unused phones per inhabitant that have not yet been disposed of. It combines estimates of smartphone stock multiplied by the survey's share of unused devices with the survey's own reported unused smartphones.

The total volume of unused phones still kept in households, expressed in millions. This multiplies unused units per inhabitant by the population.

The percentage of households that pass on their used phone by selling it into the second-hand market or giving it away outside the home. The value is derived from the household survey model, counting households that disposed of a phone and did so by selling or gifting it.

The total tonnage of e-waste generated by phone disposal each year. It is calculated by multiplying the number of handsets disposed of annually by the average e-waste weight per phone, drawing on both the “Waste over time” model and survey results.

An online survey across all 27 countries ran from 7–21 October 2020. Participants were asked about the devices in their homes, how those devices were acquired, and the methods used to discard phones during the previous 12 months.
The key questions were:
A model based on household size and geographic subregion was applied to the survey results and combined with country-level household data to produce representative values for each country. Values marked with * in the table derive from this survey.
