Question to the HM Treasury:

To ask Her Majesty's Government what assessment they have made of the level of energy use in the mining of Bitcoin, as identified by the Cambridge Bitcoin Electricity Consumption Index; and what steps they will take to address the environmental harms of cryptocurrencies.

This question was answered on 16th June 2021
The Government has been monitoring developments within the cryptoasset industry, including rising energy usage.

The Cryptoasset Taskforce, comprising HM Treasury, the Financial Conduct Authority, and the Bank of England, considers the impact of cryptoassets and assesses what, if any, regulation is required in response. The Government stands ready to respond to emerging risks or changes in the market and will continue to monitor developments in cryptoassets.

In November 2020, the Chancellor announced that the UK will implement a green taxonomy – a common framework for determining which activities can be defined as environmentally sustainable – which will improve understanding of the impact of firms’ activities and investments on the environment and support our transition to a sustainable economy. More details on the green taxonomy will be announced in due course.

The Government has already taken action to ensure the UK is the world-leading centre for green finance including through announcing an intention to make disclosures aligned with the Taskforce on Climate-related Financial Disclosures (TCFD) fully mandatory across the economy by 2025, making the UK the first country to do so.
