Marathon Digital Moves Out of Coal Powered Site in Montana
This week, Bitcoin mining was back in the news. On Tuesday, Marathon Digital Holdings (MARA) announced plans to relocate its Hardin, Montana, Bitcoin mining operations away from carbon-emitting power sources.
Marathon is one of North America‘s leading Bitcoin mining companies. With the U.S accounting for 35.4% of the global Bitcoin hashrate as of August-2021, Marathon’s carbon-neutral goals will be positive for the U.S mining community.
In 2021, Marathon announced that its mining operations would be 100% carbon neutral by 2022 end.
The transition away from a coal-fired power source to new locations with more sustainable sources of power is in line with the companys carbon-neutral ambitions.
Lawmaker Scrutiny over Proof-of-Work Mining Likely to Persist
In March, EU lawmakers voted on the EUs crypto regulatory framework, Markets in Crypto Assets (MiCA).

For the U.S government, Joe Bidens target to achieve a 50-52% reduction from 2005 levels in economy-wide net greenhouse gas pollution in 2030 has put Bitcoin mining in the spotlight.

In February, FX Empire reported on new CO2 emission numbers that brought into question the numbers circulated during the sub-committee hearing on Capitol Hill.
Some key numbers from a CoinShares paper titled “The Bitcoin Mining Network, Energy and Carbon Impact” included,
The Bitcoin mining network emitted 39 Mt of CO2 in 2021. Mining accounted for less than 0.08% of a global total of 49,360 Mt of CO2 emissions.
The global banking system emits approximately 130 Mt of CO2 emissions each year.
Also well above Bitcoin mining emissions are reportedly emissions from the gold industry. The gold industry generates between 100 and 145 Mt of CO2 annually.
