Crypto-Asset Environmental Transparency Act of 2023

This bill requires the Environmental Protection Agency (EPA) to create new reporting rules for large cryptocurrency mining operations, defined as those using at least 5 megawatts of power (either as a single facility or multiple facilities owned by the same company with combined power use). It mandates these operations to report both direct greenhouse gas emissions from their own energy use and indirect emissions from purchased electricity under the Clean Air Act. Additionally, the EPA must conduct a comprehensive study on crypto mining's environmental impacts - including emissions, energy consumption patterns, effects on communities near mining sites, and potential grid strain - and submit a report to Congress within 18 months. The study will cover locations, emissions data, public health risks, and energy sources, with $5 million in funding allocated for both the reporting rule development and the study.
