The statistics saying that one Bitcoin transaction produces 1800 tons of CO2 make no sense at all

Redditor will often use sources like this here: https://www.statista.com/statistics/881541/bitcoin-energy-consumption-transaction-comparison-visa/

It states that 1 Bitcoin transaction requires 2,264.93 kWh of energy which translates to 1.800 tons of CO2

There’s about 300.000 Bitcoin transactions daily, so over the course of a year Bitcoin alone would produce 20 billion tons of CO2

Last year globally we produced 36 billion tons of CO2, so Bitcoin alone would have been responsible for like 2/3rds of all CO2 output.

But even before Bitcoin existed we had 32 billion tons of CO2, so how does it make any sense?
