According to  in the EU 2050 scenario, electric vehicles with require 11.6 million tons of copper in the period up to 2050.
Cf . a European Union of 508 million citizens with 500 cars per thousand citizens owns a car fleet of 254 million cars (2015).
Cf [3-5], car sharing and autonomous driving are expected to reduce vehicles in use by 10-90%. This is a very wide range. We will assume a 50% reduction in car ownership compared to the 2015 level, i.e. 127 million cars.
Note that passenger-km with cars are still expected to increase 20% between 2015 and 2050 according to the EU reference scenario . For the same mileage per car, this makes the above 50% assumption effectively a 70% reduction.
In addition, car sharing will mean a shorter lifetime for vehicles since the same number of km will be served by less cars. Under above assumptions, we can expect vehicle lifetime to significantly decrease and hence end-of-life recovery of materials in vehicles becomes increasingly important.
According to , the additional copper demand for PHEV and BEV compared to ICE vehicles is:
- PHEV: ~40 kg
- BEV: ~ 60 kg
We expect however the copper use in batteries to reduce by 25% over the coming decades which would reduce above figures by respectively 5 and 10 kg. Hence, the average additional copper use per plugged vehicle would be 42.5 kg.
This leads to a copper requirement of 127 M * 42.5 = 5.4 M tonnes.

A mobile phone is typically composed of about 40% of plastic, 32% of non-ferrous metal, 20% of glass and ceramics, 3% of ferrous metal and 5% other . Metals referred to in ref  are iron, copper (16 g), silver (0.35 g), gold (0.034 g), platinum and palladium.
Ref  mentions additionally the use of aluminium, magnesium, tin, cobalt, lead, nickel, cadmium and nickel. The document provides some guidance on best practices for the end-of-life treatment of mobile phones.
Ref  refers to total 60 elements being used in mobile phones, mentioning from the metals family (in addition to above metals) tantalum, neodynium and indium. It gives good information about the recycling value-chain and its challenges.
The above three paragraphs list a total of 16 metals used in mobile phones. Based on the total use of 60 elements, and the observation that only 20-30 of the world’s 118 elements are non-metallic, the number of metallic elements used in mobile phones could be as high as 30-40.

A European Commission report gives numbers for the stock of conventional heating appliances in the EU that need to be replaced to have a decarbonised heating system. From this source, we can conclude that 143 million appliances need to be replaced. These include gas, oil or coal boilers as well as 25 million direct electrical heating systems.
From a Creara report commissioned by European Copper Institute in Feb 2017 (not published), we share the following table showing copper use in heating appliances.
The market will decide between various decarbonised heating solutions, and ECI takes no view which low-carbon solution should be preferred. Hence, the average copper use shared over the seven low-carbon solutions (two heat pump technologies, biomass boilers, pellet stoves, solar heating, district heating and domestic CHP) is 17 kg per appliance. This is 11 additional kilograms over the copper used in a conventional heating system of 6 kg.
To upgrade Europe’s 143 million conventional heating systems requires therefore 1.6 million tons of copper until 2050. This figure is likely to be an overestimate since alternative heat conductor materials can be used as well. In addition, buildings in Europe are getting more efficient and have lower heat demands.
Therefore, in an alternative scenario that anticipates societal trends rather than extrapolates business-as-usual, a much lower copper demand can for heating appliances be expected.
