Webinar | Beyond cash: A look at Bitcoin from an environmental perspective

March 14th, 2025, 18:00 (CET)

Abstract

Cryptocurrencies, particularly those based on proof-of-work (PoW) consensus mechanisms such as Bitcoin, have raised significant environmental concerns due to their high energy consumption. Cryptocurrency mining typically relies on large-scale computational operations that consume large amounts of electricity, much of which may come from non-renewable sources. This energy-intensive process contributes to greenhouse gas emissions and exacerbates global climate change. As the popularity and market value of cryptocurrencies continue to grow, so does their environmental impact, prompting calls for more sustainable alternatives or regulatory measures.

In response to these concerns, the industry is beginning to explore greener solutions. Proof-of-stake (PoS) systems, which require much less energy, are being adopted by newer cryptocurrencies and platforms, with Ethereum's transition to PoS in 2022 marking a significant milestone. Furthermore, there is growing interest in integrating renewable energy into mining operations and developing carbon offset strategies. While these efforts indicate progress, the environmental impact of cryptocurrencies remains a critical issue that demands coordinated action from developers, investors, and policymakers to align digital innovation with global sustainability goals.
