Understanding the Carbon Footprint of Bitcoin
Explanation of Bitcoin’s Proof of Work (PoW) consensus mechanism
Bitcoin, the world’s first decentralized digital currency, operates on a peer-to-peer network using a consensus mechanism called Proof of Work (PoW). In simple terms, PoW requires miners to compete against one another by solving complex mathematical puzzles. The first miner to solve the puzzle gets to add a new block of transactions to the blockchain and is rewarded with newly minted Bitcoins and transaction fees.
How PoW requires significant computational power
Solving these puzzles, however, is no easy feat. It requires substantial computational power, which translates to large amounts of electricity usage. Miners use specialized hardware, such as Application-Specific Integrated Circuits (ASICs), to increase their chances of solving the puzzles faster.
The role of energy consumption in Bitcoin mining
The energy-intensive nature of Bitcoin mining has raised concerns about its environmental impact. The energy consumption in Bitcoin mining is a significant contributor to its carbon footprint.
Breakdown of the global electricity mix for Bitcoin mining

According to estimates, approximately 69% of the global Bitcoin mining takes place in China. China’s electricity mix is diverse, with a significant portion derived from renewable sources such as hydro, solar, and wind power. However, the rest of Bitcoin mining occurs in other countries, mainly reliant on non-renewable energy sources like coal and natural gas.
Estimated proportion derived from renewable sources (solar, wind, hydro)
It is estimated that about 42% of Bitcoin’s electricity consumption comes from renewable energy sources. The majority of this share originates from China, where hydroelectric power is abundant. However, the exact proportion may vary depending on the location and electricity mix of mining operations.
The share of energy from non-renewable sources (coal, natural gas)
Conversely, approximately 58% of Bitcoin’s electricity consumption comes from non-renewable energy sources. The largest share of this portion stems from countries with heavy reliance on coal and natural gas for electricity production.
Comparison of Bitcoin’s carbon footprint to other industries and everyday activities
Comparing Bitcoin’s carbon footprint to that of other industries and daily activities can put the scale of its environmental impact into perspective. For instance, the Bitcoin network is estimated to emit around 57.34 metric tons of CO2 equivalent per year. In contrast, the aviation industry produces approximately 816 metric tons of CO2 per hour. This comparison demonstrates that Bitcoin’s carbon footprint is significant but relatively small compared to other industries and everyday activities.
