A lithium mine with the capacity to supply 700,000 electric car batteries per year is set to open in France. The massive mining project — unveiled Monday by French minerals company Imerys — will operate on the site of the existing Beauvoir kaolin quarry in Central France. The site contains one million tons of lithium, drilling surveys have revealed — enough for the extraction of 34,000 tons per year for 25 years. This metal is a crucial component in the production of electric vehicles, but mining it can also have adverse environmental consequences. The EU bloc currently imports the vast majority of what it uses. As countries and individuals try to reduce their carbon footprint, electric vehicle sales have surged. In December 2021, electric cars outsold diesel-powered vehicles for the first time in 18 European countries. In Western Europe, car buyers purchased 176,000 new EVs compared to 160,000 diesel vehicles. The EU is planning to ban the sale of combustion engine vehicles from 2035. But to meet increasing demand, suppliers require vast quantities of rare earth metals. Lithium is the most common of these metals, but graphite and cobalt are also used. To achieve climate neutrality by mid-century, the EU will require 18 times more lithium than it currently uses by 2030 and almost 60 times more by 2050. But Europe only has one operational lithium mine, in Portugal, meaning it relies heavily on imports. The EU imports 78 percent of its lithium from Chile, while the US and Russia provide 8 percent and 4 percent respectively. European Commission President Ursula von der Leyen said last month that “lithium and rare earths will soon be more important than oil and gas.” The new mine will be operational by 2028, Imerys has indicated. Petrol cars are very bad for the planet. Transport generates about a quarter of the EU"s total emissions, and road transport accounts for roughly 70 percent of these emissions. But any type of resource extraction is harmful to the planet, and lithium is no exception. This is because removing raw materials can result in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and an increase in global warming. The EU is also debating whether to classify lithium as a hazardous material, which could raise project costs. When lithium is produced using evaporation ponds, it takes approximately 2.2 million liters to produce one metric ton of lithium. New mining projects can also attract local opposition. For example, environmental protests in Serbia led the government to revoke permits held by Rio Tinto (RIO.L), (RIO.AX) for Europe"s biggest lithium project. Imerys claimed it would reduce its environmental impact by using an existing mine site — Beauvoir site is a kaolin quarry — and by using underground mining methods. — Euronews
