SANTIAGO, Jan 28 (Reuters) - Chilean state-owned miner

Codelco said on Tuesday it is planning a 25% cut in its indirect

emissions by 2030, as part of a larger decarbonization plan and

as industry demands grow for more traceable copper.

WHY IT'S IMPORTANT

Codelco is the world's largest copper producer, and mining

is a heavily polluting industry. Studies point to mining as

responsible for 4% to 7% of greenhouse gas emissions globally.

CONTEXT

Codelco plans to cut its so-called Scope 3 emissions, which

are indirect emissions put out by its suppliers and the most

difficult to reduce. These polluting "inputs" include

explosives, refractories and lubricants, Codelco said.

BY THE NUMBERS

Scope 3 emissions account for more than 60% of Codelco's

total emissions. The miner is also working to transition the 250

buses it uses to bring workers to their job sites into an

all-electric fleet. By 2030, the transition should be 40%

complete, and 100% complete by 2040.

MARKET REACTION

Codelco's plan, part of a bid to slash its overall carbon

footprint by 70% by 2030, is ambitious compared to its

competitors'. Last year, Antofagasta Minerals committed to

trimming its emissions by 10% over the same time frame, while

BHP and Teck are working to completely eliminate them by 2050.
