Bitcoin is a virtual, decentralized currency based on Blockchain technology. Regardless of where you send Bitcoin, the greenhouse gas emissions stemming from these transactions are distributed around the world. Furthermore, with the increasing public and institutional interest in Bitcoin, the value, complexity of Bitcoin mining, Blockchain networks, as well as the energy required for Bitcoin mining have been rapidly increasing. Here we show the global distribution of greenhouse gas emissions resulting from Bitcoin mining across the globe. We also estimated the carbon footprint of Bitcoin mining per transaction, per country, and per year for the last six years. The carbon footprint estimations of Bitcoin mining are calculated with consideration of the global supply-chain of Bitcoin mining around the world. According to our systematic estimations, carbon emissions are in rapid increase and there is a significant discrepancy between the locations of Bitcoin holders and the locations of emissions. China plays a major role both in emissions due to overall global mining and as a major manufacturer/supplier of Bitcoin mining equipment for all Bitcoin mining countries.
