New Research Shows That BTC’s Carbon Footprint Is Lower Than Expected
A new research piece published by The New Scientist, a prominent science magazine, has pointed out that Bitcoin (BTC) mining might not be so harmful to the climate as it was thought before. The study, which was made by Massimo Pizzol and Susanne Kohler at the Aalborg University in Denmark, criticized some notions that BTC’s mining consumption may be so high.
The study analyzed carbon emissions from electricity in China, the country with more miners in the world. By analyzing this data, the researchers believe that the results for the environment may be different than expected. The global footprint of BTC mining would not be as high as 63 megatonnes, as it was claimed before, but only 17.3 megatonnes.
This happens because the mining made in areas with more green energy harm the environment less than in other areas. Mongolia does only 12% of all BTC mining, for instance, but it is responsible for 25% of all total carbon emissions.
According to Kohler, it is important to put the data into perspective. It may be becoming harder to mine BTC, but if the mining is done with green energy, it is going to be far less harmful, which means that the means to get the energy is more important than how much energy is spent mining BTC.
Another recent study, this one made by CoinShares, affirms that 74% of all BTC mining is done with green energy, so this would be a step in the right direction. When determining how harmful BTC mining can be for the world, it is important to always use accurate data and be mindful of the latest research pieces on the subject.
