Miner Rank

The methodology employed for this sustainability ranking of Bitcoin mining is predicated on an analysis of publicly accessible information, as the internal data of the mining companies remains beyond our reach. The mining companies featured in this ranking are all publicly traded entities, which necessitates the disclosure of financial statements that contain pertinent information on operational power, hash rates, and sustainable practices. For global data, this ranking draws upon the Bitcoin Energy Consumption Index (Digiconomist, 2023) as the primary source, given its provision of the latest approximations of the annualized cumulative carbon footprint and energy consumption linked to Bitcoin mining. Regrettably, alternative data sources that are current and comprehensive are scarce. It should be noted that a constraint of this ranking system is its coverage of only approximately 22% of Bitcoin mining's total energy consumption and around 15% of its complete carbon footprint, which stems from the unavailability of comprehensive data.
