Algorand’s Commitment to Sustainable Blockchain

Algorand was built as a green blockchain with an environmental impact focus from the very beginning. Our founder Silvio Micali explained as far back as 2018 his focus on sustainability for our planet with next generation technology. With his unique consensus mechanism, Algorand is far more energy efficient than other blockchains, and is going further by offsetting its small carbon footprint in partnership with ClimateTrade.

- -CNBC: Bitcoin and blockchain consume an exorbitant amount of energy. These engineers are trying to change that.

Calculating Algorand’s Miniscule Carbon Footprint

Since the estimation of the carbon footprint strictly depends on power generation scenarios and the degree of renewables sources, I would rather address another critical metrics: the specific finalized transaction energy, that is the amount of energy spent by the whole blockchain infrastructure to finalize a single transaction and append it to the common distributed ledger.

The Importance of Low Transaction Costs & Lower Carbon Emissions to Mint NFTs
