This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
Core Scientific's Bitcoin mining facility in Calvert City, Kentucky had the largest amount of directly attributable PM 2.5 emissions out of 34 Bitcoin mines surveyed in a 2024 paper published in Nature Communications. These fine particulate emissions are immensely harmful, as their small size allows them to directly penetrate deep into the lungs and bloodstream.
The company operates a total power capacity of approximately 1.4 GW. And while they claim have you achieved carbon neutrality through the purchase of renewable energy certificates and carbon offsets, we find it difficult to believe that the scope of their program adequately compensates for the scope of their impact.
Though the company has pivoted towards high-performance computing and AI co-location, its core business remains anchored in Bitcoin mining (operating over 200,000 miners). This scale of PoW mining generates thousands of tonnes of non-recyclable ASIC e-waste and places immense strain on local energy grids, particularly in Texas and Georgia.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
