If you read the text underneath on that site, it says that their calculations are based on the average carbon dioxide production of Chinese electricity generation. As we know from Coinshares Mining Reports, this is not accurate and bitcoin uses much more renewable energy than that.

Even if you assume that number is accurate, it sounds scary but is actually incredibly small on a global scale. 37 billion kilograms of carbon dioxide. Let's put it in to context.

America consumes 12.5 billion kilograms of beef each year. Each kilo of beef produces around 25kg of CO₂, for a total of 312.5 billion kilograms. If ~10% of the US population stopped eating beef, it would offset the entire bitcoin network. We are not talking about global population, and we are not talking about all meat. Bitcoin produces the same CO₂ as 10% of one fraction of one sector in one country.
