Google's emissions up 51% as AI electricity demand derails efforts to go green
Google's carbon emissions have soared by 51% since 2019 as artificial intelligence hampers the tech company's efforts to go green. While the corporation has invested in renewable energy and carbon removal technology, it has failed to curb its scope 3 emissions, which are those further down the supply chain, and are in large part influenced by a growth in datacentre capacity required to power artificial intelligence. The company reported a 27% increase in year-on-year electricity consumption as it struggles to decarbonise as quickly as its energy needs increase. Datacentres play a crucial role in training and operating the models that underpin AI models such as Google's Gemini and OpenAI's GPT-4, which powers the ChatGPT chatbot. The International Energy Agency estimates that datacentres' total electricity consumption could double from 2022 levels to 1,000TWh (terawatt hours) in 2026, approximately Japan's level of electricity demand. AI will result in datacentres using 4.5% of global energy generation by 2030, according to calculations by the research firm SemiAnalysis. The report also raises concerns that the rapid evolution of AI may drive 'non-linear growth in energy demand', making future energy needs and emissions trajectories more difficult to predict. Another issue Google highlighted is lack of progress on new forms of low-carbon electricity generation. Small Modular Reactors (SMRs), miniature nuclear plants that are supposed to be quick and easy to build and get on the grid, have been hailed as a way to decarbonise datacentres. There were hopes that areas with many datacentres could have one or more SMR and that would reduce the huge carbon footprint from the electricity used by these datacentres, which are more in demand due to AI use. The report said these were behind schedule: 'A key challenge is the slower-than-needed deployment of carbon-free energy technologies at scale, and getting there by 2030 will be very difficult. While we continue to invest in promising technologies like advanced geothermal and SMRs, their widespread adoption hasn't yet been achieved because they're early-stage, relatively costly, and poorly incentivised by current regulatory structures.' It added that scope 3 remained a 'challenge', as Google's total ambition-based emissions were 11.5m tons of CO₂-equivalent gases, representing an 11% year-over-year increase and a 51% increase compared with the 2019 base year. This was 'primarily driven by increases in supply chain emissions' and scope 3 emissions increased by 22% in 2024. Sign up to Down to Earth The planet's most important stories.

Google's carbon emissions just went up again
Google's carbon emissions jumped yet again as the company continues to push ahead in AI. The company's 2025 sustainability report emphasizes that its 'ambition-based emissions' grew 11 percent last year to reach 11.5 million metric tons of carbon dioxide pollution, marking a 51 percent increase compared to 2019. That puts Google farther away from its goal of slashing planet-heating pollution in half by 2030 compared to a 2019 baseline. But what it calls 'ambition-based' emissions excludes certain categories of supply chain pollution it considers out of its control or'peripheral' to the core business of Alphabet, Google's parent company. That includes certain purchased goods and services and food programs. A table buried in the report's appendix shows that its total emissions actually reached 15,185,200 metric tons of carbon dioxide. That's roughly equivalent to the emissions from nearly 40 gas-fired power plants over a year. Google's report also highlights a 12 percent reduction in carbon emissions from data centers, even though its energy usage continues to rise thanks to AI. Despite the decrease, carbon emissions from data centers are still far higher when compared to 2019. In its report, Google cites several factors outside its 'direct control' that are making it more challenging to achieve its climate goals. That includes the 'rapid evolution of AI' that could make the company's 'future energy needs and emissions trajectories more difficult to predict.' It also calls out changes to climate and energy-related policies, 'slower-than-needed' deployment of carbon-free energy technologies, and a lack of carbon-free energy solutions in certain markets. 'These external factors could affect the cost, feasibility, and timeline of our progress — and navigating them requires flexibility,' Google writes. AI is driving up energy usage at other companies like Microsoft and Meta, and the technology is on track to consume more power than Bitcoin by the end of this year. Though AI companies like DeepSeek are aiming to create more energy-efficient models, that prospect isn't stopping companies like Meta from building a massive, gas-powered data center in Louisiana. President Donald Trump has also signed an executive order promoting the use of coal to power AI data centers.

New van lab for measuring carbon dioxide levels praised by scientists
The lab would start work on the streets of Wellington over the next few months. Photo: Supplied/GNS Science Climate scientists are hailing a new lab in a van as a big step forward in finding out how much carbon dioxide New Zealand cities release and how much is absorbed by green spaces. A CarbonWatch-Urban research programme, led by GNS Science, is mapping CO2 sources and sinks in every town and city. The van will access varying climates, geographies and population sizes, and will visit multiple times to account for changes in season. Spokesperson Jocelyn Turnbull said up until now, only a handful of cities around the world - including Auckland - had the technology to measure emissions, and the mobile lab with its state of the art instruments is a world first. "Getting accurate information into the hands of decision-makers is essential for emissions reduction," Turnbull said. She said the work was critical in deciding how best to reduce emissions. Jocelyn Turnbull (L) and Leigh Fleming. Photo: Supplied/GNS Science Turnbull said the van design required a bit of "Kiwi ingenuity". "Squeezing all of this high-tech equipment inside the van, and providing a rechargeable electric power supply, has required a fair bit of Kiwi ingenuity from our team and GNS's engineering workshop." The lab would start work on the streets of Wellington over the next few months.

Eco loon Ed Miliband sent aide on gas-guzzling 46-hour trip to Brazil to check out hotel despite green drive
ED Miliband's Net Zero department sent a health and safety inspector on a lavish 10,000-mile round trip – to check the hotels were up to scratch. At least one civil servant got gas-guzzling flights to Brazil and back to scout out the British delegation's accommodation for an upcoming summit on climate change. 3 3 3 The taxpayer-funded expedition was branded a 'jolly in the jungle' while the Energy Secretary was accused of hypocrisy for sending his staff 10,000 miles by plane. Civil servant John Gaunt posted sightseeing snaps on social media of his 'incredible experience' in the northern Brazilian city of Belem. He was carrying out 'H&S checks' on local hotels ahead of the UN's COP30 summit in November. Mr Gaunt, who is thought to have travelled from Heathrow via Lisbon, said he 'never dreamt I'd be travelling this far'. He added: 'Sometimes life deals you a good hand.' He revealed the journey there took 23 hours, with the same expected on the way back. The official was merely following orders, but critics attacked Mr Miliband's department for the trip which is estimated to have clocked up 11,500kg of carbon emissions. The UK also has an embassy and officials based in the South American country. Mr Miliband has previously come under fire for racking up a £40,000 bill on domestic flights during Labour's first six months in power. The former party leader has long campaigned to constrain aviation as part of his finger-wagging green drive. He has also vowed to block airports such as Heathrow expanding if they do not meet the UK's emissions targets. Last night Reform UK deputy leader Richard Tice blasted: 'In an effort to 'save the planet', Jet Ed sent a civil servant to Brazil to do a job that could've been completed with a simple Google search. 'His lunatic obsession with Net Zero seems to give him the moral superiority to waste your money. Ed Miliband won't turn Britain into a 'clean energy superpower', he'll put UP energy bills, destroy jobs and we'll have blackouts says Julia Hartley-Brewer 'The flying green hypocrite has spent over £40,000 on flights in just six months, racked up a carbon footprint more than 12 times that of the average Briton, and outspent his Tory predecessor tenfold. "All this travel to promote an agenda that will do nothing to reduce global carbon emissions, while raising energy bills for hardworking Britons and further damaging small businesses and economic growth.' Shadow Energy Secretary Andrew Bowie said: 'Red Ed's jetsetting civil servants have just been exposed for their jolly in the jungle. As per usual, it's one rule for them and another for hardworking families being asked to tighten their belts. Labour need to start practicing what they preach because it's plane hypocrisy.' UN COP conferences have been criticised as a waste of time, often ending in weak deals. Oil-rich nations are accused of using them to push their agendas rather than tackle environmental concerns. Tory ex-COP President Alok Sharma was nicknamed 'Airmiles Alok' due to his extensive international travel for climate talks. A Department for Energy and Net Zero spokesperson said: 'It is in Britain's national self-interest to attend international summits. 'Any carbon footprint is dwarfed by the carbon prize of delivering our agenda. The health and safety of our staff, while attending these events, is paramount.'
