To put in perspective just how massive that shortage would be, consider that in 2021 the global #copper deficit came in at 441,000 tons, equivalent to less than 2% of demand for the refined metal, according to the International Copper Study Group. That was enough to send prices jumping about 25% that year. Current worst-case projections from S&P Global show that 2035’s shortfall will be equivalent to about 20% of consumption.
