Coronavirus And Global Supply Chain Disruption: A Wake-Up Call For Climate Policy?

Coronavirus has slowed down economic activity and temporarily reduced China’s carbon emissions. However, there is a deeper implication for climate policy: decarbonization depends on global supply chains for inputs required for electric vehicles, solar panels, and wind turbines. 

In 2015, solar and wind contributed to about 7% of global electricity.  Their salience is projected to increase to 50% by 2050. The International Energy Agency forecasts that the number of electric cars worldwide will increase from 3 million in 2017 to 125 million by 2030.  

China dominates the global solar panel market. Supply disruptions due to coronavirus are already posing serious problems in countries such as India, which imports 80% of its panels from China. But the decarbonization problem is not about the availability of finished products. These could be manufactured in many countries. 

The strategic challenge lies in sourcing inputs, which can be found only in specific countries. Climate advocates should explain how “critical minerals” will be procured, given their skyrocketing demand. Afterall, there are technological, ecological, regulatory, and political hurdles in increasing their supplies. 

What are “critical minerals”? 

The U.S. government has identified 35 minerals critical for the economy and national security. These include lithium, nickel, cobalt, and manganese. Many of these are also essential for decarbonization. Every electric car requires 10-20 pounds of cobalt and 40 pounds of lithium! 

Within critical minerals, there is a subset known as rare earth elements, REEs (while the government puts all REEs in the critical minerals list, not all REEs are critical for the economy). REEs are especially crucial for high-tech products such as electric and hybrid vehicles. 

The US relies predominantly on imports for 29 of the 35 critical minerals. For REEs, however, it is fully dependent on imports. The political problem is that China controls 70% of global REE supplies. 

The Chinese government has not been shy of using this monopoly for political ends. In 2010, when Japanese coast guard detained a Chinese fishing trawler, China cut off REE supplies to Japan. More recently, Chinese President Xi Jinping suggested that in response to US tariffs, China may cut off REE exports to the US. 

Why Not Open New Mines and Processing Facilities? 

Critical minerals are either mined or recovered during the processing, smelting, or refining of another mineral. Mines and processing facilities tend to have a toxic legacy. Perhaps, this is why many fear that the industry will use national security (or climate change) as a ruse to weaken environmental protection laws.  Indeed, Senator Lisa Murkowski (R-Alaska) and Representative Mark Amodei (R-Nevada) have introduced “critical minerals” bills that seek to ease the mine permitting process. 

Supply shortages can be addressed in other ways as well. The 2017 Federal Critical Mineral policy notes the role of R&D in reducing critical mineral use in products. There is an opportunity to recycle minerals from discarded products. Senator Angus King (I-Maine) has proposed the “Battery and Critical Mineral Recycling Act.” For perspective, the US recycles less than 5% of spent batteries, compared with roughly 40% in Europe. 

Lessons from Blood Diamonds: New Governance Initiatives 

Many critical minerals tend to be mined and processed in conflict-prone countrieswith poor governance. Take the case of cobalt, sometimes called the “blood diamonds of batteries.” About three-fourths of the world’s cobalt originates from Congo. About 20% of this production takes place in informal artisanal mines, which have poor environmental and labor safety records. While Elon Musk has tweeted that he wants a cobalt-free battery, this may take time, even for Tesla. 

The 2010 Dodd-Frank Act required American companies to verify that tin, tungsten, tantalum, and gold they use does not originate from Congo and its adjoining countries. Given these governance gaps, several multi-stakeholder initiatives have emerged to improve environmental and labor rights in the mining industry. For example, the Initiative for Responsible Mining Assurance (IRMA), a global certification program, requires mining companies to follow the practices outlined in the Standard for Responsible Mining and subject themselves to third party audits.  

The coronavirus episode reveals the downside of globalized supply chain and the political perils of allowing China to dominate them. Without a clear mineral supply chain strategy, decarbonization by 2040 or 2050 will be challenging to achieve.
