Copper Shortage Could Derail Global 2050 EV Goals
A copper shortage threatens 2050 EV targets, prompting experts to suggest hybrid vehicles as a more realistic path to sustainable transportation

A recent study by the International Energy Forum (IEF) has sounded the alarm on a potential copper shortage that could severely impact the global shift towards EVs by 2050.

The research, co-authored by esteemed academics Dr Lawrence Cathles of Cornell University and Dr Adam Simon from the University of Michigan, warns that current copper production levels are insufficient to meet the ambitious targets set for global EV adoption.

The shortage could force a reevaluation of strategies to achieve a sustainable transportation future.

Copper demand: A looming challenge

The study emphasises the critical role copper plays in the electrification of transportation.

According to the research, global copper demand is set to rise dramatically even without the push for energy transition.

The world will need 115% more copper than has been extracted throughout human history up to 2018.

The stark projection highlights the scale of the challenge facing the automotive industry and policymakers as they work towards a low-carbon future.

A disconnect between goals and reality

Dr Cathles points out a significant "disconnect" between the ambitious decarbonisation goals and the practical realities of achieving them.

The study estimates that by 2050, annual copper mine output will need to increase by 82%, reaching 37.1 million tonnes.

However, the increase needs to meet the demands of a fully electrified global vehicle fleet.

The research suggests that to meet the 2050 EV goals, copper production will need to increase by an additional 55%, necessitating the equivalent of 194 new copper mines—approximately six new mines annually until mid-century.

The bottleneck: Copper mine development

While the study acknowledges that global copper resources are abundant, with an estimated 6.66 billion tonnes available, the real challenge lies in the extraction speed.

Bringing new copper mines online is a time-intensive process.

Historical data shows that mines that began operations between 2019 and 2022 took an average of 23 years from resource discovery to production.

The lengthy timeline poses a significant obstacle to rapidly scaling up copper production to support widespread EV adoption.

A hybrid approach: A pragmatic solution

In light of these challenges, the study's authors propose a more pragmatic approach to the transition towards sustainable transportation.

They suggest shifting focus from entirely relying on battery electric vehicles (BEVs) to a more balanced strategy that includes hybrid electric vehicles (HEVs).

Unlike BEVs, which require almost twice as much copper as traditional internal combustion engine vehicles, hybrids demand only slightly more copper.

The approach would significantly reduce the strain on copper resources and would not necessitate major upgrades to the electrical grid.

A balanced path forward

While the proposed hybrid-focused strategy has challenges, the authors argue it offers a more realistic balance between environmental goals and resource constraints.

By transitioning to 100% hybrid vehicle production by 2035, the global automotive industry could alleviate the pressure on copper supplies, making the transition to sustainable transport achievable.

The IEF study highlights the complex challenges in the global push for EVs.

As the world grapples with resource limitations, a more flexible and pragmatic approach may be necessary to achieve a sustainable future.

By considering alternatives like hybrid vehicles, policymakers and industry leaders can work together to create a balanced and achievable path towards decarbonisation, ensuring that the transition to cleaner transportation is both practical and sustainable.
