Glencore may be one of the largest companies that you’ve never heard of before reading this list. This British-owned company has headquarters in Switzerland, where it’s the largest company in the country. It is also the largest commodities trading company in the world. In 2019 it grossed $219,754,000,000.
Glencore produces and supplies mining products, metals, petroleum, agricultural products, foodstuffs, coal, and natural gas to industries all over the world. The industries include steel production, power generation, automotive, and food processing. With the environmental crisis and concerns over global warming, it may soon lose a large share of the sector that depends on fossil fuels and unsustainable mining.
