Latin America is a small coal-producing region, mining 65 million tonnes of coal in 2020, comprising less than 1% of global output.[1] While the industry is characterized by small "artisanal" mines, several large coal operations, including the Cerrejón coal mine in Colombia, are located in the region.
Nevertheless, China's unofficial import ban on metallurgical coal imports, the global Covid-19 pandemic, a shortage of labour, and unfavourable weather due to the La Niña phenomenon, which brings heavy rainfall and severe storms, have all negatively impacted Australia's overall coal production and exports in recent years, the report said.
The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity.
