Everyone knows what needs to be done to bring down CO2 levels; pump less of it into the atmosphere. But instead of reducing overall energy consumption, the focus is on increasing ‘green’ energy consumption: electric vehicles, massive electric storage installations, solar ‘farms’ and monster wind turbines. More consumption to cure the cancer of overconsumption. Ah, yes, and tree planting. Anything but serious reduction of fossil fuel consumption.
The voices calling for careful considerations of the impacts of a transition to ‘clean’ energy are drowned by the misplaced optimism of a green future. Few are asking commonsense questions that, if not answered now could easily create a worse environmental disaster later – and even compound the climate crisis. The elephant in the room few want to acknowledge is the destruction of people and the environment that will result from the hunger for so-called green energy minerals – mainly copper, cobalt, nickel and lithium.
Because of the growing demand and consequent high prices for these materials, mining companies will end up operating mega-mines in places that would otherwise be politically, environmentally, socially and/or economically unwise. These include ecologically fragile sites, biodiversity hotspots, indigenous territories, and politically unstable countries.
Some mines will deforest thousands of hectares and contaminate water resources with heavy metals. Deforestation, especially in tropical countries, will significantly reduce the Earth’s biodiversity. While the resolution adopted at the COP 26 to stop deforestation by 2030 will help somewhat, 10 more years of deforestation will bring us closer to several tipping points regarding climate, and will irremediably reduce biodiversity. Lost species cannot be brought back in 10, or 100 years’ time. Once they are extinct they are gone forever.
The biodiversity crisis, it’s worth mentioning, is considered almost as critical as the climate crisis – and the two
are intimately interrelated. Climate change is leading to loss of biodiversity; meanwhile, loss of biodiversity makes ecosystems less resilient, and less able to absorb CO2… and we all know what follows.
The environmental degradation that accompanies mining will affect other key ecosystem services, such as purifying air and water, regulating stream and river flows, and reducing erosion and flooding. These and dozens more ecosystem services are critically endangered. If we act now, we can at least try to limit the most damaging of the impacts.
Then there are the human rights violations that are so closely tied to mining. Many communities, whether indigenous or campesino, will not agree to relocate willingly. Besides violating fundamental human rights, forced relocation upsets all facets of communal and personal life, identity, livelihoods and connection with the land. And, given the amount of mining for metals needed to feed the so-called “clean energy transition”, forced relocation will be part and parcel of any such transition.
Materials
The minerals considered by the IEA report are copper, nickel, cobalt and lithium, as well as graphite and rare earths. They are sometimes referred to as the ‘critical minerals’. Given the power and greed of the fossil fuel barons and the relative failure of COP26, it is extremely unlikely the world will reach net zero emissions by 2050. But even a less optimistic scenario still calls for a
quadrupling of mineral inputs from today’s levels. That’s one hell of an increase in a relatively short time – especially when considering the social, cultural and environmental impacts mineral extraction is having right now.
Questions to ask
Following are just some of the questions we should be asking ourselves in order to avoid deepening the environmental crisis:
- Where will those minerals come from?
- Are there enough of these metals in the world to make sure that not only the wealthy citizens of the North will reap the benefits from them?
- What will be the social, cultural and environmental impacts of extracting and processing these metals?
- What steps can be taken to assure that the rights of local communities are not violated, and that they don’t end up paying the costs of producing these minerals?
- What will happen if we create an even bigger environmental crisis while trying to fix the climate crisis? And what can we do now to avoid that scenario?
Perspective
It is understandably hard to grasp the amount of land and materials that a ‘green energy’ transition will entail.
Sixty-seven tons of pure copper goes into each medium-sized off-shore wind turbine. Similarly, a plug-in electric vehicle needs 2 to 4 times more copper than the standard internal combustion vehicle. The battery in that same electric vehicle uses as much lithium as 10,000 smartphone batteries. Meanwhile, energy storage installations will need to increase capacity by
more than 20 times current levels.
Nickel is another essential component of vehicle batteries, and its production is particularly destructive. For example the contamination generated by the Norlisk nickel mine and processing plant in Russia’s Artic region
has devastated at least 350,000 hectares of forests.
In its analysis of the mineral needs for a net-zero future, the IEA did not include non-mineral materials. Balsa wood is one of these. Because of its light weight, it is highly coveted for the blades in giant wind turbines. Even though ‘balsa fever’ has only recently been an issue, it is already
causing social and environmental problems in the Amazon.
A matter of scale
Most people don’t have the slightest idea of the impacts of large-scale mining. A single such mining project can easily impact thousands of hectares of land – land that can be covered in primary tropical forest harboring dozens of endangered species of animals and plants, as well as protecting key watersheds, and mitigating the effects of climate change. The same forested land could also be a major or potential tourist draw and provide drinking water to thousands. It could also be the source of food, fiber, medicines and building materials for local communities, and be held sacred by local populations.
Because of decreasing metal content found in most metal ores, which in the case of copper can be less than 0.5% (1,000 kg of ore yields 5 kg of pure copper), the environmental impacts are hard to imagine. In the case of the La Escondida copper mine in Chile’s Atacama desert, the tailings pond alone – which is used to store toxic waste from copper processing – measures 5,500 hectares (13,375 acres). The dams holding the tailings ponds are prone to collapse, and when they do they annihilate everything in their path. In 2019, for example,
the collapse of the tailings dam at Samarco mining operations, owned by Brazilian company Vale, killed 270 Brazilians and devasted the river system in the vicinity of the town of Brumadinho. Four years earlier,
a similar disaster killed 19 locals and wiped out the town of Bento Rodrigues, creating the worst environmental disaster in Brazil’s history. The toxic sludge reached the Atlantic Ocean, 660 kilometers away.
Experts say it could take decades for the river system to recover, if at all. The mine was co-owed by BHP Billiton, the world’s largest mining corporation.
The dirty truth about clean energy metals
The low metal content in ores is accompanied by natural occurring contaminants. Heavy metals, like lead, arsenic and cadmium are almost invariably found alongside copper. Nickel ores are likewise contaminated with heavy metals.
Then there is the issue of scale. The largest open-pit operations can move almost one million tons of material (both ore and waste) per day. They do this 365 days a year. To break up the hard rock that these metals are found in, as well as to access the metals, millions of pounds of explosives are used. The Bingham Canyon copper mine in Utah, for example,
uses 1,000 tons of explosives per day. And the deeper the miners have to go to access the metals, the more dire the environmental impacts.
One could sum up the situation regarding mining and ‘green metals’ in one simple phrase from a
2020 United Nations Conference on Trade and Development report: “Most consumers are only aware of the ‘clean’ aspects of electric vehicles,” says Pamela Coke-Hamilton, UNCTAD’s director of international trade. “The dirty aspects of the production process are out of sight.”
Mining and Poverty
Cases like that of the DRG, and Zaire, two important copper exporters, highlight a well-known curse associated with the dependence of developing countries on exporting raw minerals to rich ones.
Niger, exporter of uranium, and
Ghana exporter of gold, are both affected by high rates of poverty, just one aspect of the phenomenon that has come to be known as the
natural resource curse: countries rich in natural resources are often afflicted by poverty, corruption, authoritarian governments, and violent conflict.
African nations are not alone in this. Bolivia, which has for centuries enriched other countries with its tin and silver, is still plagued by endemic poverty (and it has now opened itself up to lithium investments). Meanwhile, the some of the poorest Mexican municipalities are precisely
where most gold mines are located. The same applies to the
mining provinces in Peru.
These are the countries and sites that many companies had avoided because of political instability. But with demand for green energy metals raising their price, corporations are now
willing to consider them as investment opportunities.
One deeply troubling aspect of the new green metal rush is that the miners and governments will keep going out of their way to avoid correctly valuing the other types of wealth within a mining concession, including the value that ecosystem services provide local communities and the world. Some of these are mentioned above, and include erosion prevention, regulating stream flows, biodiversity conservation, and ironically, mitigating the effects of climate change.
There is a reason for such perversity. For if mining companies were forced to put a real price tag on ecosystem services and all other kinds of wealth within a proposed mining project that would be negatively affected, the balance would be invariably tilt in favor of protecting these areas. As you can imagine, this kind of information is the last thing that mining companies and the buyers of their ‘green energy metals’ want to acknowledge, at least publicly
Getting Real
There is a real possibility that what I am presenting will be seen as alarmist and exaggerated. Let me bring it all home by using an example not too distant from where I live, the Intag region of northwest Ecuador. Approximately 15 kilometers away as the parrot flies, several transnational mining corporations have been trying to develop a large-scale open pit copper mine. The Llurimagua mining concession is within the Tropical Andes, the most diverse of the world’s Biodiversity Hotspots. It is covered in primary cloud forests, which not only protect dozens of species of animals facing extinction, but also 43 sources of rivers and streams.
All of this is in one mining concession of less than 5,000 hectares (12,500 acres). Some animals that make their home in the orchid-rich forest are critically endangered. These include a fish species and three frogs, two of which have been reported nowhere else on the planet. Several primates who live here are also on the list of endangered species, including the Brown-headed Spider Monkey, one of the most threatened primates in the world. Pumas, ocelots, and the Andean bear are likewise inhabitants of this biodiverse wonderland.
A 1990’s preliminary environmental impact study prepared by experts for a small copper mine in this area predicted that the mining operations would deforest so much land that the local climate would dry up. The study also predicted contamination of rivers with lead, arsenic, chromium and cadmium. Four communities would have to be relocated to make room for the mine and its accompanying infrastructure. The study did not analyze the impact to thousands of farmers who depend on rain for their livelihood.
Then, the following year, the company inferred that the copper deposit could be five times larger. In 2018, Codelco reported that the Llurimagua copper deposit could even be much, much larger. The Llurimagua area is not, by any means, unique.
These are precisely the biological and cultural jewels and human rights that the growing demand for green metals is putting at risk. Companies know this, and are taking steps to insulate themselves from the loss of reputation that will come from producing or buying metals from these sites. It is what is motivating mining corporations and the buyers of their products, including car manufacturers, to join organizations that will supply them with certificates of compliance with social and environmental standards. Instead of certifying the companies, the organizations certify individual mines, which means a company can sell its reputation based on one mine, but produce and sell dirty metals from the rest of its portfolio. Currently, there are dozens of these greenwashing outfits. Keep tuned because more are bound to sprout up in the coming months and years.
The main objective of this text is not to be alarmist, nor to prevent an energy transition. It is to draw attention to its peril and consequences. And, to motivate a serious discussion in order to avoid the impacts to people and the environment briefly detailed above.
The most important measures to take right now are to create red lines with local stakeholders in order to keep mining and other extractive industries out of these special sites. One of the most important is respecting the right of local populations to decide their own future. Consultations need to be genuine, and if consent is given for extractive activities, it needs to be done freely, without pressure and only after thoroughly knowing the proposed activities’ impacts. Sacred lands, biodiversity hotspots, native forests and habitats harboring endangered species must be off-limits to mining. Given that mining can contaminate water in perpetuity, projects that pose a risk of contaminating water sources with heavy metals or cancerous substances must be strictly prohibited. Mining too, has no place in the world’s seabeds or the Artic. These are just some of the no-go sites that governments must exclude from mining if we are not to aggravate the existing environmental crisis and create new ones.
More than enough damage has been done to cultures, species and whole ecosystems sacrificing them in the name of economic development. Now it is being done in the name of the clean energy transition. A transition that will be anything but clean if the materials come from these special places.
Isn’t that the same mentality that got us where we are today?
