Tech giants' indirect emissions rose 150% in 3 years as AI expands, UN agency says
[GENEVA] Indirect carbon emissions from the operations of four of the leading AI-focused tech companies rose 150 per cent on average from 2020 to 2023, due to the demands of power-hungry data centres, a United Nations report said last week.
The use of artificial intelligence (AI) by Amazon, Microsoft, Alphabet and Meta drove up their global indirect emissions because of the vast amounts of energy required to power data centres, the report by the International Telecommunication Union (ITU), the UN agency for digital technologies, said.
Indirect emissions include those generated by purchased electricity, steam, heating and cooling consumed by a company.
Amazon's operational carbon emissions grew the most at 182 per cent in 2023 compared with three years before, followed by Microsoft at 155 per cent, Meta at 145 per cent and Alphabet at 138 per cent, according to the report.
The ITU tracked the greenhouse gas emissions of 200 leading digital companies between 2020 and 2023.
Meta, which owns Facebook and WhatsApp, pointed Reuters to its sustainability report that said it is working to reduce emissions, energy and water used to power its data centres.

Amazon said it is committed to powering its operations more sustainably by investing in new carbon-free energy projects, including nuclear and renewable energy. Microsoft highlighted its sustainability report, which says it doubled its rate of power savings last year and is transitioning towards chip-level liquid cooling designs, instead of traditional cooling systems, to reduce energy consumption at its data centres.
The other companies did not respond immediately to requests for comment.
As investment in AI increases, carbon emissions from the top-emitting AI systems are predicted to reach up to 102.6 million tons of carbon dioxide equivalent per year, the report stated.
The data centres that are needed for AI development could also put pressure on existing energy infrastructure.
'The rapid growth of AI is driving a sharp rise in global electricity demand, with electricity use by data centres increasing four times faster than the overall rise in electricity consumption,' the report found.
It also highlighted that although a growing number of digital companies had set emissions targets, those ambitions had not yet fully translated into actual reductions of emissions. REUTERS

Meta in talks for scale AI investment that could top US$10 billion
[NEW YORK] Meta Platforms is in talks to make a multibillion-dollar investment into artificial intelligence startup Scale AI, according to people familiar with the matter. The financing could exceed US$10 billion in value, some of the people said, making it one of the largest private company funding events of all time. The terms of the deal are not finalised and could still change, according to the people, who asked not to be identified discussing private information. A representative for Scale did not immediately respond to requests for comment. Meta declined to comment. Scale AI, whose customers include Microsoft and OpenAI, provides data labelling services to help companies train machine-learning models and has become a key beneficiary of the generative AI boom. The startup was last valued at about US$14 billion in 2024, in a funding round that included backing from Meta and Microsoft. Earlier this year, Bloomberg reported that Scale was in talks for a tender offer that would value it at US$25 billion. This would be Meta's biggest ever external AI investment, and a rare move for the company. The social media giant has before now mostly depended on its in-house research, plus a more open development strategy, to make improvements in its AI technology. Meanwhile, Big Tech peers have invested heavily: Microsoft has put more than US$13 billion into OpenAI while both and Alphabet have put billions into rival Anthropic.

Sign Up Sign Up Part of those companies' investments have been through credits to use their computing power. Meta does not have a cloud business, and it is unclear what format Meta's investment will take. Chief executive officer Mark Zuckerberg has made AI Meta's top priority, and said in January that the company would spend as much as US$65 billion on related projects this year. The company's push includes an effort to make Llama the industry standard worldwide. Meta's AI chatbot – already available on Facebook, Instagram and WhatsApp – is used by one billion people per month. Scale, co-founded in 2016 by CEO Alexandr Wang, has been growing quickly: The startup generated revenue of US$870 million last year and expects sales to more than double to US$2 billion in 2025, Bloomberg previously reported. Scale plays a key role in making AI data available for companies. Because AI is only as good as the data that goes into it, Scale uses scads of contract workers to tidy up and tag images, text and other data that can then be used for AI training. Scale and Meta share an interest in defence tech. Last week, Meta announced a new partnership with defence contractor Anduril Industries to develop products for the US military, including an AI-powered helmet with virtual and augmented reality features. Meta has also granted approval for US government agencies and defence contractors to use its AI models. The company is already partnering with Scale on a programme called Defense Llama – a version of Meta's Llama large language model intended for military use. Scale has increasingly been working with the US government to develop AI for defence purposes. Earlier this year the startup said it won a contract with the Defense Department to work on AI agent technology. The company called the contract 'a significant milestone in military advancement.'

Meta in talks over Scale AI investment that could exceed $10 billion, Bloomberg reports
Meta Platforms is in talks to make an investment that could exceed $10 billion in artificial intelligence startup Scale AI, Bloomberg News reported on Sunday. The terms of the deal were not yet finalized and could still change, the report said, citing people familiar with the matter. Scale AI declined to comment and Meta did not immediately respond to Reuters request for comment outside regular business hours. Founded in 2016, Scale AI is a data labeling startup backed by tech giants Nvidia, Amazon and Meta. Last valued at nearly $14 billion, Scale AI also provides a platform for researchers to exchange AI-related information, with contributors in more than 9,000 cities and towns.
