Fingerlakes1.com Menu Greenidge Generation says its bitcoin mining operation is going to be carbon neutral beginning this year. Effective June 1, the company says it will operate an entirely carbon neutral bitcoin mining operation at its facility in Dresden. Greenidge will purchase voluntary carbon offsets from a portfolio of U.S. greenhouse gas reduction projects. Each project has been reviewed and certified by one of three well recognized Offset Project Registries, the American Carbon Registry (ACR), the Climate Action Reserve (CAR) and Verra, ensuring that any projects funded by Greenidge reduce emissions or increase sequestration of greenhouse gas in a manner that is real, permanent, and verifiable.
