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.

Google Engineer Charged Over Polymarket Bets.

US federal prosecutors have charged a Google software engineer with allegedly using confidential company data to make more than $1.2 million through prediction market bets on Polymarket.

According to the US Department of Justice, Michele Spagnuolo allegedly accessed internal Google search trend information before it became public and used the data to place profitable bets under the online alias “AlphaRaccoon.”

Prosecutors say Spagnuolo used insider knowledge connected to Google’s annual “Year in Search” rankings. Authorities claim he placed high-risk bets on unexpected names, including musician D4vd and rapper Kendrick Lamar, before official search trend results were released.

The US Department of Justice charged him with commodities fraud, wire fraud, and money laundering. Officials say insider trading threatens the integrity of emerging prediction markets and financial systems.

The case highlights growing concerns surrounding the rapid expansion of prediction market platforms like Polymarket. Regulators increasingly worry that confidential information could be exploited for gambling-style financial gains.

Google confirmed that using confidential internal data for betting violates company policy and stated that the employee has been placed on leave while investigations continue.

The complaint also states that Spagnuolo currently resides in Switzerland, adding international attention to the case. Federal prosecutors in New York say they will continue targeting corporate insiders who misuse sensitive information for personal profit.
