Mining giant Glencore's decision to cap its coal production will not halt the growth of Australia's exports, despite claims it represents a shift away from coal.

Glencore, Australia's largest coal miner, will cap its global output at its current level of about 145 million tonnes a year in the wake of pressure from activist shareholders as part of a pivot towards minerals used in renewable energies.

The company also told investors it recognised the increasing risks associated with climate change.
