Except that we do not have an alternative to jet airplanes that moves hundreds of times more passengers while emitting less carbon. We do have such an alternative to Bitcoin, in fact it predates Bitcoin by decades and is far more popular: Visa. Visa's total carbon emissions in 2020 for its data centers and offices (their ESG report also discusses emissions from employee commuting and business travel) is a whopping 14 thousand metric tons, over 1000 less than Bitcoin. That carbon was emitted as Visa processed 1700 transactions per second compared to only 7 transactions per second for Bitcoin. In other words, as an electronic payments system, Visa is roughly one million times less polluting than Bitcoin. So until NFTs are using a system at least as energy-efficient as Visa, I'll continue to worry... |
