Cryptocurrencies have faced severe criticism for their environmental impact, especially as traditional investments increasingly focus on greener ESG values. The question remains: how soon can crypto secure its green credentials?
The Environmental Footprint of Crypto
The United Nations University Institute for Water, Environment and Health revealed that between 2020-2021, Bitcoin's networks had a massive carbon footprint equivalent to burning 38 billion tonnes of coal. Additionally, its water footprint could satisfy the domestic needs of over 300 million people in sub-Saharan Africa. According to the Cambridge Blockchain Network Sustainability Index, Bitcoin's energy consumption surpasses that of countries like Norway and Sweden, posing a significant challenge for investors aiming to meet ESG goals.
The Need for Regulation
The crypto market has long been viewed as a “get-rich-quick” scheme with minimal regulation, complicating the path towards sustainable practices. Sceptics highlight issues such as money laundering, scamming, and price manipulation that plague the industry.
Decarbonising the Crypto Industry
Recognizing the need for change, many in the crypto sector signed the Crypto Climate Accord (CCA) in 2021, aiming for 100% renewable energy for blockchains by 2025 and net-zero emissions by 2030. Companies like Mara and Argo are developing energy-efficient technologies to minimize mining energy consumption, while some cryptocurrencies are transitioning to less energy-intensive mechanisms like proof-of-stake (POS).
A Path Towards Sustainability
The shift towards greener practices is facilitated by organizations like the Financial Stability Board, which aim to create frameworks for achieving ESG compliance. This collective effort could pave the way for a future where environmentally conscious investors can confidently engage with cryptocurrencies.
