The ongoing debate about crypto’s energy cost, sustainable finance’s greenwashing, and Aspiration launches tree-planting credit card

Tearsheet’s Green Finance newsletter is about the intersection of money and the environment. We’ll be in your inbox every other week, and share what we’re currently thinking about, and what’s been happening at three key areas in the intersection: corporate responsibility, blockchain, and green products and services. You can subscribe here.

With a $2+ trillion market cap, crypto is an unignorable financial force. The amount of energy it takes to power crypto is a challenge, or an opportunity — depends who you ask. Not too long ago we spoke to Paxos’ CEO Charles Cascarilla about the common likening of crypto’s energy cost to that of a whole (small) country. He said, ‘We spend more energy digging gold out of the ground than mining crypto.’ And in essence — it’s worth it. 

In a recent NYT podcast, data scientist Alex de Vries called ‘sustainable crypto mining’ a paradox, an impossibility. Mining currencies via proof of work — such as with Bitcoin and Ethereum, which have the largest market cap today —  is a process fundamentally based on useless calculations, ie. energy waste. These digital assets come with a very tangible environmental impact.

Currencies validated via proof of stake, on the other hand, don’t tax the environment nearly as much, and are competing for audience favorites, according to Tezos creator Kathleen Breitman. 

So, is crypto’s promise of economic democracy worth the energy cost? Do we just need to put it in perspective? Or, will we realize in hindsight that crypto mining has been waging unnecessary costs on our environment, and that the market doesn’t always know best?
