Why we need global cooperation on critical mineral supplies

Barely a day goes by without another government announcing a plan to diversify and create sustainable, resilient, clean energy supply chains.

The stated rationale typically invokes some variant on the theme of a fast-evolving and geopolitically charged global resources landscape involving trade in critical minerals. Recent examples include the EU’s Critical Raw Materials Act, or Australia’s talks with India on critical mineral trade.

The International Energy Agency (IEA) has highlighted several minerals required for clean energy technologies. Individual governments' designations will vary according to national priorities, resource endowments or vulnerabilities.

Recent breakthroughs in sodium-ion battery technology underscore how innovation might alter the utility of a given mineral. Nevertheless, as things currently stand - lithium, nickel, cobalt, manganese and graphite are key to the performance, longevity and energy density of batteries.

Rare earth minerals are essential components of wind turbines and electric vehicles (EVs), and copper and aluminium permeate nearly all electricity-related technologies.

Today, the energy sector accounts for over two-thirds of global greenhouse gas (GHG) emissions. The IEA estimates that overall mineral requirements for the climate transition could double by 2040, and to meet the climate goals set out in the Paris Agreement, these requirements would quadruple.

Although scaling clean energy deployment will require a significant increase in mineral extraction and processing, the current debate over supply security is driven as much by scarcity concerns as parallels drawn by commentators with Europe's dependencies on Russian gas, or China's dominance in many critical mineral supply chains, especially but not only in processing.

While these dependencies differ in nature, it is ill-advised to be overly dependent on any single state for any critical inputs. The EU, for example, stipulated that no more than 65% of any key raw material should come from any single country.

First, it will be challenging to reach consensus as to which minerals are deemed critical.

There is also little consensus on how best to reconcile the national pursuit of supply resilience – often framed as a contest against geopolitical rivals – while still keeping the cost of decarbonization manageable at speed and ensuring that those same adversaries can access the materials needed to reach global climate goals.

In the current climate, talk of a multilateral approach or any global cooperation can sound naïve if not worse. Many major economies like the G7 have responded to geopolitical strife by approaching the question of supply security from the zero-sum, mercantilist lens of national industrial policy, emphasising access to critical minerals for their burgeoning industries tied to local content requirements and jobs. Yet framing the need for supply security through narrowly-defined vantage points ignores key issues at one’s peril.

Geopolitical leanings aside, attempts to de-risk global supply chains by moving production will likely add immediate costs and inefficiencies that hinder the speed of global uptake of clean energy technologies.

Even though many countries are moving fast to acquire or build this manufacturing capacity, ultimately no countries or even regions can be self-sufficient when it comes to the full range of raw materials and processing needs for the energy transition. You can’t do it alone, even within the purview of ‘climate clubs’.

As the pace of energy transition hastens, it is also evident that the same barriers to scaling clean energy investments are also pertinent to that of critical minerals projects, especially in developing country regions of high political risks. This means the need for a common framework that helps safeguard the socio-environmental bar in new extractive projects.

Whether it is equity, or necessity, demonstrating how mineral development will bring positive social benefits on the ground not only for the elites is a must – not only because it is the right thing to do but because it will strengthen the resilience of resource security.

Without a cooperative framework, export restrictions could continue to dampen prospect to scale deployment of clean energy as illustrated the case of Indonesia for nickel and China for germanium and gallium did.

Last but not least, parallel technology systems could be cost-ineffective and cumbersome in ways that further slow the deployment of cleantech at the pace needed.

Of course, the world is beset with duelling imperatives. Western governments are stepping up in their quest to dominate the production of the next generation of green tech, with developing countries at best deemed trusted suppliers of raw materials. Yet if mineral-producing countries would limit access to those who would process on-site, it could undermine the scale economy and drive costs up.

All these challenges highlight the need for cooperative frameworks that could start as open partnerships that could comprise some or all the following elements:

The Financial Times recently described the current geopolitical order as that of an à la carte world, where any pre-fixe menu of assumed allegiances is open for challenge and maybe eschewed, in this case, perhaps by mineral-rich countries.

This is why any cross-border cooperation will likely take place only in the form of ad hoc, case-by-case groupings, or what are often described as the coalitions of the willing or the capable.

This is also why, rather than go it alone or divide up the world in a new ‘land grab’ for control over critical resources, economies that profess to want to lead on climate action and the clean energy transition, such as G7 countries, should seek supply chain partnerships, open to all and any to join, that would embrace the five principles above.
