Transparency in copper procurement: Südkupfer‘s Product Carbon Footprint Report

Transparency in copper procurement: Südkupfer‘s Product Carbon Footprint Report

The last Südkupfer story about sustainability in the copper market was published in July 2023. Since then, we have consistently continued to pursue this challenging and highly relevant topic at Südkupfer. Over the past twelve months, Südkupfer has estimated its Scope 1 and Scope 2 emission values for the 2022 and 2023 financial years. The emission values for copper purchasing are also available now. For Südkupfer as a trading company in the copper market, the focus is on Scope 3 values and copper purchasing in particular. Copper purchasing at Südkupfer represents more than 99% of the total emissions. This was the decisive factor behind the idea of developing a report for our customers on the product carbon footprint (PCF) of copper cathodes purchased or provided for them.

IT-supported algorithms enable transparency in the supply chain

The high complexity in context of copper releases and tolling agreements was a real challenge in developing the report. In contrast to the traditional supply chain, in which the raw material is delivered directly from the supplier to the customer, in the tolling business may appear several upstream producers between us and the purchasing customer. The copper purchased from Südkupfer is generally not delivered directly to the customers, but is allocated to their upstream producers. The inflow of the material is documented on a so-called “copper account”. The upstream producer can either make the copper account balance available to another upstream supplier by releasing it from the account or have the copper physically delivered. This process can be continued as often as required. Tracing all releases and physical delivery processes are exclusively possible at the end of this chain by help of an IT-supported algorithm.

Südkupfer delivers copper cathodes to several upstream producers in the supply chain continuously. These copper cathodes originate from many different cathode producers who manufacture their own brand, so-called “copper cathode brands”. The cathode brands provide information of the origin and the quality of the cathode to the processor, for example. Some manufacturers publish information on the recycling content and PCF of the cathode brands on top. We went into this in more detail in last year’s story already. Südkupfer has to take additional factors into consideration when supplying cathodes: For quality reasons, some upstream suppliers require a ‘cathode mix’ defined for their production process. They use a brand list to determine which cathodes are accepted and which are nonaccepted.

The key figures regarding emission factors and the proportion of secondary material can vary greatly from cathode brand to cathode brand. In this context it is useful to have a look at the emission factors for copper cathodes published by the Federal Office of Economics and Export Control. It shows an average PCF of 6,658 kgCO2e/tonne of copper cathode¹. Another calculation for a global average value is published in a study by the International Copper Association (ICA). The result of the ICA-analysis is a value of 3,965 kgCO2e/tonne of copper cathode². The ICA’s figure is significantly lower, as the study was based exclusively on data from ICA members.

The average value of the ICA is part of the PCF calculation

The ICA approach is more suitable for Südkupfer’s PCF reporting as our supplier base is well covered by the ICA. For cathode brands whose PCF has not yet been published or if the brand is unknown, our system takes the ICA average. For all other cathode brands, the PCF published by the cathode manufacturer is calculated. Our investigation resulted in an average PCF of 2,756 kgCO2e/tonne of copper cathode for 2022 regarding the copper cathodes purchased by Südkupfer during this period.

However, with our PCF report we intend to offer the highest level of transparency to our customers. We do not content ourselves with calculating and publishing just the average PCF, but track the PCF of each customer individually according to the releases made in the reporting quarter. Therefore, our customers receive a report on an average PCF and a recycling rate that reflects their individual supply chain per quarter. Depending on the release-practice of the customers or their upstream suppliers, the PCF and recycling rate can fluctuate quarterly.

The evaluation process starts with tracking which cathode-brands and volumes have been delivered by Südkupfer to the several cathode-processing upstream producers in the respective quarter. On this basis an average value can be calculated. In a second step, it is possible to track how much copper has been released by each customer from the upstream suppliers by tracing the customer’s release-orders in the relevant period. The average PCF and the average recycling rate are redistributed to customers depending on the quantity released then. An average value is calculated on this basis again. This process continues until all of the customer’s releases are mapped.

Thus, the physical supply chain of copper cathodes is pictured as accurately as possible. Our customers receive the PCF and the recycling rate of the copper that was delivered in their physical supply chain. We must point out that this procedure only covers the copper purchased by Südkupfer. Südkupfer has no influence on the PCF and recycling rate of the material that is used in fact by the upstream producer in its production process.

Our report in relation to specialized products such as “Green Copper”

Some cathode manufacturers differentiate between regular and special copper cathodes. The special products have better characteristics in terms of CO2 footprint and recycling rate. A surcharge on the cathode premium must be paid for these special products generally. As a return service the customer receives a certificate attesting the purchase of a particularly ‘green’ cathode. The use of ‘green copper’ cathodes is not included in the calculation of Südkupfer’s PCF report. This is due to the customer receives the certificate from the manufacturer directly and the better values should benefit the buyer straight. That means that an average is announced for the regular cathodes and the buyer of ‘green copper’ cathodes can also offset the certified value of these special cathodes in a next step. This ensures that PCF and recycling rate of the ‘green copper’ cathodes have a direct impact on the buyer’s individual calculation.

The Copper Market in Transition

The Copper Market in Transition

In the meantime, this raw material, which is required significantly for the energy transition, has even been included in the EU’s “list of critical raw materials”. The term “critical raw materials” is used in case of high economic relevance and concerns about supply risks at the same time. Whilst future supply risks are being discussed on one side, the market requirements for the red metal are increasing on the other. Quality characteristics and quality standards, which have characterized copper purchasing for many years, are now being extended by sustainability factors. This changes the market requirements for the raw material and influences purchasing decisions and strategies in a new way. Is the availability of “sustainable” copper high enough to meet the demand required for the energy transition? There could be tensions between new market requirements and sourcing risks.

“Sustainability” will change the Copper World

In the meantime, the megatrend “sustainability” has become an integral part of our society. In fact, it has come to stay. The United Nations established this trend with the announcement of the 17 “Sustainable Development Goals” (SDG) in 2015. The outlined goals forced the implementation of national strategies, which are reflected in our present and future laws and market requirements. Examples of the increasing legal and regulatory requirements for companies in Germany are the EU Conflict Minerals Regulation, the Supply Chain Act (German: Lieferkettensorgfaltspflichtengesetz (LkSG)) or the Corporate Sustainability Reporting Directive (CSRD). It’s a fact – the course for sustainability has been set and will shape our society as well as the economy.

Although the increase in regulatory requirements and new market conditions are very challenging for the copper business, these changes offer great opportunities, especially due to the upcoming decarbonization of the energy sector. Either electric vehicles or wind turbines: the energy transition will require high volumes of the industrial metal. The primary target is to achieve CO2 neutrality by 2050. The way to CO2 neutrality thereby pays entirely to SDG 13 “Climate change mitigation and adaptation”. Even though copper is essential to achieve CO2 neutrality, it shouldn’t be forgotten that the electrolysis process in copper production is very CO2 intensive. This leads to a kind of conflicting targets. In order to resolve this conflict as best as possible, many cathode manufacturers have committed themselves to sustainability. The CO2 emissions per ton of copper, the so-called “Product Carbon Footprint” (PCF), is included in the sustainability reports of numerous copper producers already. While the global average CO2 footprint for one ton of copper is 4 tons CO2 equivalent (CO2e), the sustainability report of Germany’s largest copper smelter Aurubis shows a PCF of 1.46 tons CO2e per ton of copper cathodes. According to the report, this figure has decreased by 36% since 2013. The german company aims to achieve climate neutrality before 2050.

Effective methods to further reduce these figures are the use of green electricity and the use of recycled materials. Copper can be recycled any number of times, that turns the recycling process into the ultimate tool for improving the CO2 footprint. In this way, producers are able to optimize the energy-intensive process from mining to the electrolysis process. A good example is the PCF of the cathode production at Montanwerke Brixlegg. The Austrian recycling company uses recycled copper to produce cathodes and achieves an exceptionally low PCF of 0.739 tons of CO2e per ton of copper cathodes. In Germany half of the demand is currently covered by recycled material. However, given the threat of supply problems for the upcoming energy transition, the capacity of recycled copper is far away from being enough to cover the total demand.

Outlook

Given the risks of sourcing described above, the question is how to set the course in the copper market in the event of a bottleneck situation. Will a lower CO2 footprint for copper be pushed further or will the society accept higher CO2 emissions from copper in order to accelerate the energy transition and support the future reduction of CO2 emissions afterwards?

Copper – indispensable for the energy transition

The energy transition is accelerating

Even before that, the climate crisis led to a greater expansion of renewable energy production. The Ukraine war is now acting as an additional accelerator of this development. Many countries and companies are massively increasing their investments in renewable energies in order to become climate-neutral and energy self-sufficient in the near future. In order to become independent of russian gas and oil more quickly in this country, the output of wind energy plants is to double in the future, that of solar plants even quadruple.

By 2050, Europe is to become the first continent to emit only unavoidable greenhouse gases and to completely offset these few emissions in order to achieve a global temperature increase of as little as possible below 1.5 degrees.

Copper demand is likely to increase exponentially in the future.

With all these efforts, there is no way around copper, because copper is found everywhere where electricity is transmitted. Accordingly, the demand will be great in the future to further advance and expand the megatrends of decarbonisation, e-mobility and digitalisation.

According to a market analysis by the financial services provider S&P Global, the expansion could be delayed due to the limited availability of the industrial metal. Solar power plants require twice as much, offshore wind power plants up to five times as much copper per megawatt hour as classic power plants.

“The energy transition will be much more dependent on copper than our current energy system,” Daniel Yergin, vice chairman of S&P Global, told US broadcaster CNBC.

In its report, S&P Global forecasts that annual global copper demand will almost double to 50 million tonnes by 2035 and that this demand will even reach more than 53 million tonnes by 2050.

Cumulatively, the copper consumption of the next 28 years would exceed the total copper consumption of the last 120 years. With the conversion from fossil to renewable energy sources, the required quantities multiply very quickly.

Last year, the investment bank Goldman Sachs even ushered a new era in its study, calling copper the new oil – “no decarbonisation without copper”. Goldman Sachs expects that the demand for wind turbines alone will account for 20% of the copper demand from renewable energies. Electromobility will require up to 40%, mainly for charging infrastructure and motors.

The Berenberg bank takes a similar view and even spoke of a super-cycle for industrial metals in the coming decades, triggered by decarbonisation.

The recent price slide of 35% is therefore likely to be only a snapshot, as the fundamental demand drivers will remain in place in the future.

Copper deposits and availability

If the demand for copper is set to double by 2035, what about the supply?

Copper deposits, unlike many other commodities, are spread across the globe and can be found in over 20 countries. According to the International Copper Study Group (ICSG), the largest producing countries in 2019 were Chile, Peru, China and the USA. Other significant deposits are found in Australia, Indonesia, Russia, Canada, Zambia, Poland, Kazakhstan and Mexico.

Global copper reserves are currently estimated at around 870 million tonnes. According to data from the US Geological Survey, global copper resources total 5,000 million tonnes. In addition to existing reserves, these include discovered and potentially profitable deposits as well as undiscovered deposits predicted on the basis of preliminary geological surveys.

In addition, 35% of the demand is currently already covered by recycled copper. Every wind turbine and every cable is therefore a potential source of copper for the future.

Outlook

Driven by the megatrend of “decarbonisation” and the energy transition, it can be assumed that the copper demand will increase exponentially in the coming years. It is true that copper deposits are available globally on a large scale. However, the question will be whether extraction possibilities and capacities can keep up with the growing demand.

Copper as an all-round metal

What is copper used for?

Copper is mainly processed in various electrical installations, e.g. in cables, wires, conductor boards, batteries or electrical appliances. This accounts for 57% of the total 1.2 million tonnes of copper in Germany. A further 15% is used in the construction industry, mainly for installation pipes or as facade cladding. 9% is used in the automotive sector, 8% in mechanical and plant engineering. Only 5% goes into traditional trade. Copper is also used in door locks, fittings, musical instruments, coins or bells. Copper is therefore a real all-round talent.

Hardly any other raw material has been processed more frequently in human history than the red metal, which was already known in the Stone Age.

A rapid increase in copper demand is expected due to the production of electric vehicles. At the moment, most passenger cars contain an average of 25 kg of copper. For electric cars, however, carmakers will need up to 80kg in the future (according to the mining group BHP Billiton). Experts even expect the demand to grow by up to 340% by 2050.

However, if the demand for the popular industrial metal continues to grow so significantly, neither the reserves mined by now nor the actually known resources, will be able to meet the demand. One way to prevent this shortage is to conserve resources through recycling.

Copper can be recycled without any loss of quality.

Recycling conserves resources, reduces environmental impact and saves energy. Copper is probably the most recycled material in the world because the metal can be reprocessed without any loss of quality. Mankind therefore does not consume copper – it uses it. Theoretically, all the copper that has ever been mined can be used forever. The trade with scraps, used material for copper and copper alloys is a well organised market since many years. However, according to the United Nations Environment Programme (UNEP), the global recycling rate is only 50%.
