From its launch in 2015 until the Merge, Ethereum's greenhouse gas emissions totalled 27.5 million tonnes carbon dioxide equivalent (MtCO2e), the study showed. Its current yearly emissions are around 2.8 kilotonnes carbon dioxide equivalent, the study found - around the same as five round-trip flights from London to New York. It is generally thought that blockchain is "a highly emitting technology," said Anna Lerner, executive director at the Ethereum Climate Platform, an organisation that seeks to use blockchain tech to accelerate climate finance. The annual emissions of Bitcoin, the largest blockchain and cryptocurrency, are therefore roughly equivalent to those of Cambodia in 2020, according to Climate Watch.

REUTERS/Edgar SuLONDON, Sept 27 (Reuters) - Bitcoin is struggling to go green, with the cryptocurrency making only slim gains in its usage of sustainable energy in the year to January, research by Cambridge university showed on Tuesday. Processing bitcoin transactions and "mining" new tokens is done by powerful computers, hooked up to a global network, that compete against others to solve complex mathematical puzzles.

Bitcoin mining is mostly unregulated and opaque, with few centralised bodies gathering data. The Cambridge study was based on data on the geographical spread of mining across the world and the energy mix of individual countries.
