Coal giant Glencore says its carbon emissions will fall 30% by 2035

Miner will not set climate targets, but will produce less coal as reserves are depleted

Mining giant Glencore has predicted its carbon footprint will shrink by almost a third by 2035, but will not set climate targets for the company.

The company expects its total carbon emissions to fall by 30% in the next 15 years as it gradually produces less coal due to the "natural depletion" of its coal reserves.
