Swiss Study Finds Bitcoin Generates High CO2 Emissions.

A new Swiss study has highlighted the significant environmental impact of Bitcoin, revealing that a single Bitcoin transaction generates approximately 486 kilograms of carbon dioxide (CO2). The research was conducted by the Lucerne University of Applied Sciences and Arts in partnership with Swiss Economics on behalf of Germany’s Federal Environment Agency.

The findings underline the growing debate surrounding the environmental sustainability of cryptocurrencies. According to the study, Bitcoin remains one of the most energy-intensive digital currencies due to its mining process, which requires vast computing power and substantial electricity consumption.

Bitcoin mining involves thousands of computers worldwide competing to validate transactions and create new coins. This process, known as Proof of Work, consumes large amounts of energy and contributes significantly to global carbon emissions.

In contrast, the study found that Ethereum generates only around 0.003 kilograms of CO2 per transaction. This figure is even lower than the emissions associated with a transaction through online payment platforms such as PayPal. Ethereum’s lower environmental footprint is largely due to its transition away from energy-intensive mining systems.

Researchers note that the difference between Bitcoin and Ethereum highlights how blockchain technology can vary dramatically in terms of sustainability. While Bitcoin continues to face criticism for its environmental impact, newer blockchain systems are increasingly adopting energy-efficient approaches that significantly reduce electricity consumption.

The study adds to ongoing global discussions about the future of cryptocurrencies and their role in climate policy. As governments and regulators focus more closely on sustainability, environmental performance is expected to become an increasingly important factor in the development and adoption of digital currencies.

Experts believe the findings could encourage further innovation in the crypto industry, pushing developers toward greener technologies that balance financial innovation with environmental responsibility.
