Yesterday we sent a comment letter to the Office of Science & Technology Policy in the @WhiteHouse.

We urged @POTUS to curb the climate pollution associated w digital currencies relying on increasing amounts of electricity to mine & validate transactions.

Unlike other industries that are subject to energy efficiency standards or pollution limits, crypto mining is like the wild, wild west right now.

With no guardrails to protect our climate and our economy, miners will do whatever makes them the quickest and easiest buck.
Miners increasingly rely on fossil fuels: The CO2 emissions from mining Ethereum & Bitcoin in 2021 equaled the tailpipe emissions of over 15 million gas-powered cars.

The most recent #IPCC report in April called soaring energy use of digital currencies a “growing concern.”
The mining of digital currencies that use “proof of work” is driving environmental disasters all over the country.

Some Bitcoin mining operations have revived old fossil fuel plants, incentivizing continued use of coal & gas, increasing noise pollution.

We urge the @EPA to institute rules and regulations to mitigate the harms of cryptocurrency mining and protect local communities, including stringent reviews of every air and water permit issued or renewed for proof-of-work mining operations.
We encourage @ENERGY to study how best to institute reforms for proof-of-work crypto miners.

A minimum energy efficiency limit could ensure that the methodology to mine crypto is the best available technology and uses the least amount of electricity.
Financial regulators should require greater transparency regarding electricity use & climate pollution, to place limits on the environmental threats posed by these digital assets, and to address the serious risks Bitcoin poses to supply chains and electricity prices/availability.
We are grateful for the Biden Administration's commitment to combat the climate crisis. We urge @POTUS to act to protect us all from the carbon pollution from certain types of digital currency.
