Consortium launches effort advocating changes to the cryptocurrency\u2019s code<\/h2>\n\n\n\n

A consortium of environmental groups launched a campaign on Monday seeking to change bitcoin\u2019s code to decrease its energy use, which has grown substantially in the past few years.<\/p>\n\n\n\n

Bitcoin is popular among some investors, but its energy use has riled environmental groups, alarmed some lawmakers, and put the cryptocurrency at odds with a green movement that has some supporters on Wall Street. The new campaign aims to persuade people involved with the cryptocurrency, from mining companies to investors to software developers, that a change is better for the environment and bitcoin\u2019s reputation and support.<\/p>\n\n\n\n

Greenpeace USA, Environmental Working Group and others will run ads in media outlets such as the New York Times, Politico and The Wall Street Journal highlighting bitcoin\u2019s environmental impact and advocating for change. The campaign is funded by Ripple co-founder Chris Larsen, who isn\u2019t representing the cryptocurrency firm in this endeavour. Mr. Larsen said he provided $5 million.<\/p>\n\n\n\n

Some of the ads are aimed at prominent bitcoin backers, such as Tesla Inc. Chief Executive Elon Musk, Block Inc. founder Jack Dorsey and Fidelity Investments Chief Executive Abby Johnson.<\/p>\n\n\n\n

The campaign isn\u2019t anti-bitcoin, said Michael Brune, the former executive director of the Sierra Club who is advising the campaign. Rather, he said, it argues that climate change has reached a critical point, and bitcoin, the most valuable cryptocurrency in terms of market capitalization, is contributing too much to global warming.<\/p>\n\n\n\n

\u201cIt\u2019s important for anyone in a position to act, to act,\u201d he said. \u201cYou can\u2019t ignore that we are in a climate emergency.\u201d<\/p>\n\n\n\n

The goal is to persuade bitcoin\u2019s community of investors and backers to change the network\u2019s code, removing the \u201cproof of work\u201d mechanism that requires bitcoin \u201cminers\u201d to expend a certain amount of energy while processing transactions to earn rewards in newly created bitcoin. The change could drastically reduce bitcoin\u2019s energy use, Mr. Brune said.<\/p>\n\n\n\n

Bitcoin\u2019s energy usage is a defence mechanism designed to protect the network. Because it is an open-source project, anybody can run the bitcoin software. But the network requires miners to expend vast amounts of computing power to make it prohibitively expensive for somebody to take over the network, which could allow them to create counterfeit bitcoins or erase transactions.<\/p>\n\n\n\n

The Cambridge Centre for Alternative Finance estimates that the bitcoin network uses slightly more energy a year, 134.9 terawatt hours, than Norway, at 124.3 terawatt hours. The research institute said, however, that bitcoin uses less energy than is lost in the U.S. during electricity transmission.<\/p>\n\n\n\n

Some bitcoin miners have addressed the issue by using more renewable energy sources to power their computers, but Messrs. Brune and Larsen think that isn\u2019t enough.<\/p>\n\n\n\n

Bitcoin\u2019s environmental effects have been an issue for years, but the people in control of it have rejected the kinds of changes being proposed. Moreover, because bitcoin isn\u2019t owned by a company, changing the code requires nearly all of the parties involved in its maintenance\u2014something on the order of 90% or more\u2014to agree on a change.<\/p>\n\n\n\n

The Ethereum network also uses proof of work, but is changing to a model called proof of stake, which essentially swaps energy for cryptocurrency. That change, the implementation of which has been delayed several times for technical reasons, is expected to reduce Ethereum\u2019s electricity usage by 99%. The campaign is hoping to effect a similar switch for bitcoin.<\/p>\n\n\n\n
