Senator Questions Government Regulation of Crypto Mining’s Energy Use

• The Senate held a hearing on March 7 to discuss the potential environmental impacts of cryptocurrency mining.
• Senator Cynthia Lummis (R-Wyoming) expressed concern about the use of energy efficiency standards to target crypto mining operations.
• The Crypto-Asset Environmental Transparency Act requires miners utilizing over 5 megawatts of power to disclose their emissions data, while the EPA is tasked with evaluating these emissions.

Senate Holds Hearing on Crypto Mining and Environment

The United States Senate held a hearing on March 7th to discuss the potential impacts of cryptocurrency mining on the environment. Chair Ed Markey (D-MA) introduced the Crypto-Asset Environmental Transparency Act in December, which seeks to enforce disclosure of emissions by crypto miners and obligate the Environmental Protection Agency (EPA) to evaluate those emissions.

Senator Lummis Questions Government’s Role in Regulation

During the hearing, Senator Cynthia Lummis (R – Wyoming) emphasized that energy efficiency standards must not be used to target particular energy use cases like crypto mining. She questioned Rob Altenburg, director of Penn Future Center, an environmental think tank, about whether it was Congress‘ role to legislate how energy use is deployed and pointed out similarities between mining for cryptocurrency and electric vehicles.

Crypto-Asset Environmental Transparency Act

The Crypto-Asset Environmental Transparency Act would require miners utilizing over 5 megawatts of power to disclose data about their emissions while obligating EPA to study the impact of such miners on greenhouse gas emissions. According to Chair Markey, carbon dioxide emissions for bitcoin mining are equivalent to annual emissions from as many as 7.5 million gasoline cars in the U.S., illustrating why this bill is necessary for understanding and addressing any potential negative effects that could arise from crypto mining operations.

Potential Challenges Ahead

Despite its importance, some are concerned that this legislation could lead to overregulation or even stifle innovation within the industry if implemented incorrectly or too broadly without providing adequate guidance or alternatives for crypto companies seeking compliance solutions. As such, it will be important for policymakers and industry stakeholders alike to ensure there is an appropriate balance between regulation and innovation going forward so as not harm either one unnecessarily or excessively.


In summary, this hearing highlighted both sides‘ evidence regarding how cryptocurrency affects the environment; however more work needs done in order determine how best regulate this space going forward in order protect all involved parties while still allowing innovation thrive within industry itself
