Can Bitcoin mining reduce greenhouse gas emissions?

YES

Some oil field operators are letting companies use their excess natural gas to power Bitcoin mining, reducing greenhouse gas emissions by putting otherwise-wasted energy to use.

Oilman Magazine reported recently that portable Bitcoin mining systems from a Denver company, Crusoe Energy Systems, are operating at 20 oil fields around the U.S. They convert unused natural gas, a byproduct of oil extraction that is often not profitable enough to capture and sell, into electricity at the well to supply energy for the computing needs of Bitcoin miners. The process of creating new digital currency or Bitcoin “mining” is energy intensive, accounting for as much as 0.3% of global electricity use.
The gas would otherwise be "flared" (i.e., burned) or “vented” (i.e., emitted directly into the air), producing carbon dioxide in the former case and methane, a more potent greenhouse gas, in the latter.

ABOUT THE CONTRIBUTOR
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
