Thanks to a court ruling to which AIDA and our allies contributed, Canadian authorities must allow active participation in all mining and industrial megaprojects, as well as comprehensive environmental impact assessments.
The decision came after a long legal battle that began in 2006. That year, an open-pit copper and gold mine called Red Chris was approved without the adequate evaluation of its environmental impacts. It was sleighted to process 30 thousand metric tons a day.
The Imperial Metals company intended to build the mine in the Kapplan River Valley, a remote and pristine natural area home to large mammals such as Dali’s sheep, caribou, bears and moose. In addition, the area is part of the migratory salmon route and the Tathlan indigenous community lives nearby.
The company had fragmented the project into small parts to avoid evaluating the full impact of the project, thus violating international standards and the right to public participation.
In 2009 AIDA filed a brief with Canada’s Supreme Court in support of a lawsuit filed against the project by MiningWatch and Ecojustice.
The ruling remains a powerful tool to protect huge expanses of pristine and valuable land for its biodiversity, water sources, and the culture of indigenous communities.
It was a watershed moment in terms of ensuring companies fulfill their obligations when developing projects that put at risk the natural environment and those who depend on it.

Coal, a dirty and obsolete fuel
Historically, coal has been identified as an important source of non-renewable energy. It was the fuel that powered the Industrial Revolution, transforming the world's production methods, and for a long time, it was the main fuel for transportation, electricity generation, and heating.But it is time to leave that era behind. Today, we know that coal is the fossil fuel that generates the highest carbon dioxide (CO2) emissions, one of the main greenhouse gases driving global warming, with effects such as melting glaciers and rising sea levels.In addition to climate and environmental arguments, there are economic, political, and human rights reasons to end the extraction and burning of this fuel.To better understand why coal is so polluting and what its impacts are on the environment and health, we have taken a closer look. Getting to know coalCoal is a rock formed from plant remains that were buried in layers of sediment and did not decompose due to the absence of oxygen.Over millions of years, through geological processes, this organic matter was exposed to high temperatures and pressures. The result was a material composed mainly of carbon.The energy in coal is released during combustion. When burned, coal generates heat. In thermoelectric plants, this heat is used to generate steam and produce electricity.When coal is burned to produce heat or electricity, it releases large amounts of carbon dioxide and, in smaller amounts, methane and nitrous oxide into the atmosphere.All these gases harm the environment and human health. Why is it so polluting?Coal has an impact from the moment it is extracted, as open-pit coal mining involves excavating and removing large amounts of earth to reach the coal-rich layers.This means destroying landscapes, razing vegetation and animals, and even causing the forced displacement of populations.Coal mining also pollutes water and soil at extraction sites, both through mining the mineral and through the waste it generates.But the chain of impacts does not end there. During coal combustion, large amounts of CO2 are generated, the main gas responsible for global warming.At the same time, other gases are released during its extraction, handling, and combustion:Methane, which has a global warming potential up to 30 times greater than CO2 over a 100-year period.Nitrous oxide, whose global warming potential over a 100-year period is up to 273, and whose lifetime in the atmosphere extends up to 109 years. In addition to greenhouse gases, coal combustion also releases other pollutants, such as nitrogen oxides, sulfur dioxide, and black carbon (soot), which affect air quality and have indirect effects on the climate, including altering precipitation patterns and contributing to acid rain. What damage does it cause to health?Despite the known environmental and health impacts of coal, for many economies it remains a reliable and cheap energy source.Following the decline in coal consumption during the COVID-19 pandemic, global demand for coal has grown by more than 1.2 billion tons since 2020, according to the International Energy Agency's Coal 2024 analysis.Despite increased electricity generation from renewable sources, major consumers such as China and India continue to rely on coal.In Latin America, the future of coal is uncertain. On the one hand, the region continues to extract coal for export or for burning to generate energy. The most emblematic case is Colombia, the world's fifth-largest coal exporter.On the other hand, there are efforts towards decarbonization, such as in Chile, where coal-fired power generation has caused serious health and environmental impacts in so-called “sacrifice zones.”The government proposed a plan to have the entire National Electric System generate 100% clean energy by 2050. However, the recent accelerated burning of surplus coal at a thermoelectric plant, as part of its closure process, has put the spotlight on how this decarbonization is being carried out.As a coal-producing and consuming region, Latin America has a share of responsibility in global efforts to curb coal mining and burning and instead promote energy systems based on non-conventional renewable sources that are sustainable over time and respectful of the environment and people.Ending the coal era is possible. It is time to do so.

The importance of the “how” in the energy transition
Of the global carbon dioxide (CO2) emissions from fossil fuels, one of the main causes of the climate crisis, nearly half come from coal use. Latin America is no stranger to the problem because it participates in both coal burning and the extraction of the mineral, which, after export, is used as a fossil fuel source in other parts of the world.In this context, the closure of coal-fired power plants—as is happening in Chile—is both great news and an opportunity to steer the energy transition toward justice.But in a just energy transition, the "how" matters: every step toward defossilization must ensure energy systems based on non-conventional renewable sources, respect for the environment and human rights, and responsible closure and exit processes. Thus, the Chilean case, which we explain below, is an important example of why the region needs to implement responsible decarbonization. When decarbonization causes more pollutionIn early 2024, AES Andes SA closed the Norgener thermoelectric power plant in Tocopilla, a coastal city in northern Chile. As part of the closure process, the company rapidly burned the 94,000 tons of coal it had stored at the plant, affecting a city already saturated with pollution and publicly recognized as an environmental sacrifice zone.The population of Tocopilla was exposed to potential health effects, including impacts on the respiratory system, increased risk of heart attacks, and—in children—perinatal disorders, developmental disorders, and impaired lung function, among others.The forced burning of coal was authorized by the National Electricity Coordinator (CNE)—the agency responsible for managing the various energy sources that enter the national electricity system—and displaced the use of renewable energy. To stop the burning, AIDA, Greenpeace, and Chile Sustentable, together with local communities, filed an appeal with the Santiago Court of Appeals to halt it, but the court's decision came after the coal had already been burned. Furthermore, the court ruled that the case should be reviewed by a specialized court in a more lengthy proceeding. A bad precedent for Chile and for the continentBy authorizing the burning of the remaining coal from the Norgener thermoelectric plant, the National Electricity Coordinator made an exception to the law governing the order of energy dispatch. Shortly thereafter, in September 2024, the agency issued an internal procedure to order the early closure of power plants. Although it is an attempt to streamline the closure process, the measure opens the door for other companies with coal-fired power plants in the process of closing to replicate what happened at Norgener: burn their remaining coal under the argument of “emptying stock” and generate energy that enters the national electricity system with priority, once again displacing energy from renewable sources. In Chile, the National Electricity Coordinator decides which unit dispatches its energy to the system at any given time based on a criterion of increasing economic merit, according to which the energy with the lowest variable cost enters first. However, the internal procedure stipulates—without sufficient regulatory backing—that the agency may authorize dispatching energy outside economic order so that coal-fired power plants consume their remaining fuel before closing. In response, AIDA, Greenpeace, Chile Sustentable, and MUZOSARE (Women in Sacrifice Zones in Resistance) filed a complaint on February 6, 2026, with the Superintendency of Electricity and Fuels against the Coordinator and his advisors for approving and implementing the measure. The complaint represents an opportunity to do things right: for the sector's regulatory body to ensure that the planning for the closure of thermoelectric power plants does not end up rewarding poor coal inventory management at the expense of communities' health and a just energy transition. What the energy transition needsIn 2019, the Chilean government committed to closing all coal-fired power plants in the country by 2040. Since that public announcement, the timeline has been accelerated. But the urgency of decarbonization should not be used to favor companies operating thermoelectric plants or to harm communities near polluting industries. Doing so weakens Chile's climate leadership and sets a bad example for any decarbonization process in the region. In a just energy transition, companies along the entire coal and other fossil fuel supply chain have an obligation to ensure the responsible closure and exit of their operations. The energy transition is not merely a change in technologies; it is an opportunity to rethink energy and development models and to correct injustices. This requires clear and appropriate rules that promote energy system security, competition, and a healthy environment.

5 key facts about “rare” earth elements
In recent weeks, you have probably read or heard the term "rare" earth elementsContrary to what their name suggests, they are more common in everyday life than you might think. In fact, many of the technological innovations we use daily would not be possible without them.So why are they being talked about so much right now?Because today, "rare" earth elements and other minerals considered "critical" are at the center of disputes over their control, given their usefulness in the manufacture of technologies for the energy transition and for the military industry.But aside from the geopolitical tensions surrounding the issue, there are basic questions that arise when we hear this term, which is why we answer them here.By understanding where the raw materials behind the technologies we use come from, we can also rethink the kind of future we want. What are "rare" earth elements?There are 17 metallic elements, similar in their geochemical properties, used in many of today's technologies, from cell phones to electric cars.They include the 15 lanthanides of the periodic table of chemical elements—lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium—as well as scandium and yttrium.Promethium is usually excluded from this group because under normal conditions its half-life is short. Are they really rare?Contrary to what one might think, they are not "rare" in abundance, but rather in concentration. In other words, deposits with high concentrations are rare, making their exploitation and processing difficult. As a result, most of the world's supply comes from a few sources.But when they were discovered (in the 18th and 19th centuries), they were less well known than other elements. The most abundant "rare" earth elements are similar in concentration in the Earth's crust to common industrial metals (chromium, nickel, copper, zinc, molybdenum, tin, tungsten, or lead). Even the two least abundant rare earth elements (thulium and lutetium) are almost 200 times more common than gold. What are "rare" earth elements used for?They have unusual fluorescent, magnetic, and conductive properties, making them attractive for a wide range of applications.They are present in everyday objects such as smartphones, screens, and LED lights.In renewable energy, they are used to manufacture wind turbines and electric cars.Its most specialized uses include medical devices and military weapons. Where are they?They exist in various parts of the world, but just because a country has reserves does not mean that it exploits them. The countries with the largest reserves are:China: 44 million tons.Brazil: 21 million tons.India: 6.9 million tons.Australia: 5.7 million tons.Russia: 3.8 million tons.Vietnam: 3.5 million tons.United States: 1.9 million tons.Greenland: 1.5 million tons.In Latin America, besides Brazil, other countries where "rare" earth elements have been identified are Argentina, Chile, Bolivia, Colombia, and Peru. Why is there so much talk about them now?The energy transition is intensifying competition for access to raw materials—including rare earth elements—needed for renewable energy technologies.To promote and facilitate access to these and other resources, some countries and international organizations refer to them as "critical."But they are not only important for renewable energy. "Rare" earth elements are also key to the military industry.Because global supply is concentrated in a few sources, there is growing interest among some countries in the Global North in controlling access to these resources. What are the impacts of their exploitation?The extraction of "rare" earth elements is mainly carried out in open-pit mines, which have serious environmental and social impacts:Water, air, and soil pollution.Heavy use of water and toxic chemicals.Radioactive waste.Loss of biodiversity.Health risks.Forced displacement of communities.Increased risk of economic inequality. "Rare" earth elements and other minerals considered "critical" are at the center of current debates over who controls their exploitation and production.As these are natural resources, often found in indigenous territories and critical ecosystems, a more urgent discussion is what kind of progress we want: one that encourages the excessive exploitation of resources, or one that respects the environment and people?
