Visualizing Copper’s Global Supply Chain

Published

on

Copper is all around us: in our homes, electronic devices, and transportation.

But before copper ends up in these products and technologies, the industry must mine, refine and transport this copper all over the globe.

Copper’s Supply Chain

This infographic comes to us from Trilogy Metals and it outlines copper’s supply chain from the mine to the refinery.

Copper's Supply Chain

Copper Deposits Around the World

Copper is a mineral that comes from the Earth’s crust. However, natural history did not evenly distribute it around the world. There are certain geological conditions that need to happen to make an economic deposit of copper.

There are two primary types of copper deposits:

  1. Porphyry Copper Deposits

    These copper ore deposits form from hydrothermal fluids coming from magma chambers below the copper deposit. These are currently the largest source of copper in the world.

  2. Sediment-hosted Copper Deposits

    These are copper deposits that occur in sedimentary rocks that are bound by layers. They are formed by the cooling of copper-bearing hydrothermal fluids.

Copper-containing rock or ore only has a small percentage of copper. Most of the rock is uneconomic material, known as gangue. There are two main copper ore types in mining: copper oxide ores and copper sulfide ores.

Both ore types can be economic, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for ~50% of copper production.

Sulfide copper ores are the most profitable ores because they have high copper content, and refiners easily separate copper from the gangue. Sulfide ores are not as abundant as the oxide ores.

Copper Trade Flows

While copper is a global business, there are clear leaders in the production and refinement of copper based on geology and demand. Chile is the major source for copper, exporting both mined and refined copper.

In a list of the 20 biggest copper mines, 11 reside in Chile and Peru accounting for 40% of mined copper. Meanwhile, China is a leading importer and exporter of refined copper, and it’s home to 9 of the 20 biggest copper smelters in the world.

Copper Imports/Exports

However, this concentrated geography of supply creates risks for the the copper trade.

Inherent Risks

While Chile is one of the richest sources of copper in the world, the mining industry has exploited copper deposits to the point where the grade or quality of the copper ore is declining.

Codelco, the national copper miner of Chile and the world’s largest producer of copper, plans to spend $32B by 2027 to extend the life of its current mines and maintain its copper output.

In addition to declining grades, the geography of copper mining exposes the risk of supply disruption by natural forces.

The borders of Chile and Peru overlap the intersection of the Nazca and the South American Tectonic plates. Movement of these plates can produce powerful earthquakes.

According to one study, regions in Chile and Peru face a greater than 85% chance of a serious earthquake in the next 50 years, potentially disrupting copper mining operations. And according to Wood Mackenzie, a 15-day closure of copper mines in Chile and Peru could wipe out 1.5% of global annual production, or 300,000 tons of copper.

Falling grades and tectonic risk suggest that mining costs are likely to increase, making copper production more expensive and new discoveries more valuable.

Copper for the Future: New Discoveries

As economies grow and infrastructure needs increase, the demand for copper will grow. However, without new discoveries and sources of production, the world could face a shortage of the red metal.

According to data from S&P and the London Metals Exchange, the discovery of copper has not kept up with investment in copper exploration. If this trend persists, there will not be enough copper to replace current resources. On top of this, production from already producing copper mines face resource exhaustion and declining grades.

In order to maintain copper’s supply chain, the world needs new copper discoveries to ensure everyone has access to the materials and products that make modern life.

An Introduction to MSCI ESG Indexes

With an extensive suite of ESG indexes on offer, MSCI aims to support investors as they build a more personalized and resilient portfolio.

An Introduction to MSCI ESG Indexes

There are various portfolio objectives within the realm of sustainable investing.

For example, some investors may want to build a portfolio that reflects their personal values. Others may see environmental, social, and governance (ESG) criteria as a tool for improving long-term returns, or as a way to create positive impact. A combination of all three of these motivations is also possible.

To support investors as they embark on their sustainable journey, our sponsor, MSCI, offers over 1,500 purpose-built ESG indexes. In this infographic, we’ll take a holistic view at what these indexes are designed to achieve.

An Extensive Suite of ESG & Climate Indexes

Below, we’ll summarize the four overarching objectives that MSCI’s ESG & climate indexes are designed to support.

Objective 1: Integrate a broad set of ESG issues

Investors with this objective believe that incorporating ESG criteria can improve their long-term risk-adjusted returns.

The MSCI ESG Leaders indexes are designed to support these investors by targeting companies that have the highest ESG-rated performance from each sector of the parent index.

For those who do not wish to deviate from the parent index, the MSCI ESG Universal indexes may be better suited. This family of indexes will adjust weights according to ESG performance to maintain the broadest possible universe.

Objective 2: Generate social or environmental benefits

A common challenge that impact investors face is measuring their non-financial results.

Consider an asset owner who wishes to support gender diversity through their portfolios. In order to gauge their success, they would need to regularly filter the entire investment universe for updates regarding corporate diversity and related initiatives.

In this scenario, linking their portfolios to an MSCI Women’s Leadership Index would negate much of this groundwork. Relative to a parent index, these indexes aim to include companies which lead their respective countries in terms of female representation.

Objective 3: Exclude controversial activities

Many institutional investors have mandates that require them to avoid certain sectors or industries. For example, approximately $14.6 trillion in institutional capital is in the process of divesting from fossil fuels.

To support these efforts, MSCI offers indexes that either:

  • Exclude individual sectors such as fossil fuels, tobacco, or weapons;
  • Exclude companies from a combination of these sectors; or
  • Exclude companies that are not compatible with certain religious values.

Objective 4: Identify climate risks and opportunities

Climate change poses a number of wide-reaching risks and opportunities for investors, making it difficult to tailor a portfolio accordingly.

With MSCI’s climate indexes, asset owners gain the tools they need to build a more resilient portfolio. The MSCI Climate Change indexes, for example, reduce exposure to stranded assets, increase exposure to solution providers, and target a minimum 30% reduction in emissions.

An Index for Every Objective

Regardless of your motivation for pursuing sustainable investment, the need for an appropriate benchmark is something that everyone shares.

With an extensive suite of ESG indexes designed specifically for sustainability and climate change, MSCI aims to support asset owners as they build a more unique and personalized portfolio.

Tracked: The U.S. Utilities ESG Report Card

As emissions reductions and sustainable practices become more important for electrical utilities, environmental, social, and governance (ESG) reporting is coming under increased scrutiny.

Once seen as optional by most companies, ESG reports and sustainability plans have become commonplace in the power industry. In addition to reporting what’s needed by regulatory state laws, many utilities utilize reporting frameworks like the Edison Electric Institute’s (EEI) ESG Initiative or the Global Reporting Initiative (GRI) Standards.

But inconsistent regulations, mixed definitions, and perceived importance levels have led some utilities to report significantly more environmental metrics than others.

How do U.S. utilities’ ESG reports stack up? This infographic from the National Public Utilities Council tracks the ESG metrics reported by 50 different U.S. based investor-owned utilities (IOUs).

What’s Consistent Across ESG Reports

To complete the assessment of U.S. utilities, ESG reports, sustainability plans, and company websites were examined. A metric was considered tracked if it had concrete numbers provided, so vague wording or non-detailed projections weren’t included.

Of the 50 IOU parent companies analyzed, 46 have headquarters in the U.S. while four are foreign-owned, but all are regulated by the states in which they operate.

For a few of the most agreed-upon and regulated measures, U.S. utilities tracked them almost across the board. These included direct scope 1 emissions from generated electricity, the utility’s current fuel mix, and water and waste treatment.

Another commonly reported metric was scope 2 emissions, which include electricity emissions purchased by the utility companies for company consumption. However, a majority of the reporting utilities labeled all purchased electricity emissions as scope 2, even though purchased electricity for downstream consumers are traditionally considered scope 3 or value-chain emissions:

  • Scope 1: Direct (owned) emissions.
  • Scope 2: Indirect electricity emissions from internal electricity consumption. Includes purchased power for internal company usage (heat, electrical).
  • Scope 3: Indirect value-chain emissions, including purchased goods/services (including electricity for non-internal use), business travel, and waste.

ESG Inconsistencies, Confusion, and Unimportance

Even putting aside mixed definitions and labeling, there were many inconsistencies and question marks arising from utility ESG reports.

For example, some utilities reported scope 3 emissions as business travel only, without including other value chain emissions. Others included future energy mixes that weren’t separated by fuel and instead grouped into “renewable” and “non-renewable.”

The biggest discrepancies, however, were between what each utility is required to report, as well as what they choose to. That means that metrics like internal energy consumption didn’t need to be reported by the vast majority.

Likewise, some companies didn’t need to report waste generation or emissions because of “minimal hazardous waste generation” that fell under a certain threshold. Other metrics like internal vehicle electrification were only checked if the company decided to make a detailed commitment and unveil its plans.

As pressure for the electricity sector to decarbonize continues to increase at the federal level, however, many of these inconsistencies are roadblocks to clear and direct measurements and reduction strategies.
