Zumo releases cross-sector report on decarbonising the crypto industry
By Taylor Griffin · 25 October 2021

Crypto wallet and payments platform, Zumo,has today announced the release of a new report ‘Decarbonising Crypto: A state of play’. The report is a cross-sector effort to explore the carbon footprint of cryptocurrencies and the task of decarbonisation. It also explores the complexities of decarbonisation and how the perception of cryptocurrencies’ environmental impact compares to other sectors such as traditional finance.
‘Decarbonising Crypto: A state of play’ includes input from leading sustainability researchers and cryptocurrency experts including Energy Web, Cambridge University Centre for Alternative Finance, The Green Bitcoin Project, The Digiconomist and TAAL Distributed Information Technologies. These organisations participated in a Zumo roundtable event held in September that was the foundation for this paper. Key findings and recommendations contained in the report include:
- Urgent progress is needed towards decarbonisation of the sector, but the data/research that currently exists is not widely understood, and can be taken out of context
- The carbon footprint of crypto is a partisan and highly emotive issue, and this has often obscured the path to open and reasoned debate
- Decarbonising crypto is a collective responsibility, which requires collaboration across the crypto ecosystem, encompassing miners, exchanges and holders
- Technologically speaking, crypto can be decarbonised relatively easily. Cryptocurrency has key advantages of transparency and comparative simplicity, which makes it a prime candidate for rapid decarbonisation. By comparison, the carbon footprint of other sectors such as traditional finance consist of many more elements and are harder to decipher. A recent WWF/Greenpeace report has shown the financed emissions of UK financial institutions to be almost double the UK’s net emissions
- For society to fully accept and adopt the benefits of crypto, the industry needs to become relatable to the public and demonstrate its utility/value to a wider audience
- New blockchain technology could transform the perception of cryptocurrencies and significantly reduce energy consumption. A prime example is Ethereum pivoting from a proof-of-work to proof-of-stake model
