COP31 puts AI's energy bill on the climate summit agenda
Two stories about who pays for the AI buildout: the UN's climate summit just put the technology's energy bill on its agenda, and a security startup raised $400 million on the fear that agents will break into everything.
"Energy-guzzling artificial intelligence is driving up planet-heating pollution from coal, oil and gas, while ratcheting up energy costs for households and businesses," UN climate chief Simon Stiell said in a New York speech this week, adding that AI leaders are "on thin ice when it comes to license to operate, and sinking deep underwater when it comes to public support."
The venue matters as much as the line. Stiell spoke during New York Climate Week with the UN General Assembly in session, and Türkiye's COP31 presidency used the same week to announce the Antalya Pledge on AI — a "political" commitment, in its own framing, covering how AI is "designed, procured, powered, deployed, measured and managed" in support of climate action. COP31 president Murat Kurum put the ask plainly: "We must openly discuss AI's growing energy consumption and it is time for governments to start setting the terms."
The numbers underneath are why the summit hosts moved. Global climate-tech venture funding reached $26 billion in the first half of 2026, 55% above the same period last year, with products and services for data centres taking the largest share — while carbon management and low-carbon fuels lost investment, because those products have no data centre to sell to. The International Energy Agency expects data-centre emissions from electricity use to more than double between 2024 and 2030, and around 70% of the power behind China's data centres still comes from coal.
Two things are worth holding onto. The pledge is a political commitment with no draft text yet — COP31 says a draft arrives before the summit opens in Antalya in early November, and it has not said whether governments or companies will be asked to sign. And the IEA's own estimate is that existing AI applications could cut more emissions than data centres add. Both can be true; what changed this week is that the question sits on the summit's agenda instead of in a footnote. The politics the pledge is trying to get ahead of is already here — 61% of Americans now oppose local data centers, the ground we covered in The Take — the data center backlash is the new NIMBY tax on AI.
Dallas-based browser security startup Island raised $400 million at a $6.4 billion valuation, announced Thursday, with Evolution Equity Partners leading the round. CEO Mike Fey framed the market in one line: "Every old control is breaking, so everything's up for grabs." Island plans to push into Europe, Asia and the Middle East and to grow from 1,000 employees to 1,500 by the middle of next year; Pfizer, Chipotle and American Airlines are among its customers.
The valuation is a step-up, not a spike. Island was worth $3 billion in 2024 and $4.8 billion after a $250 million round in March 2025, so $6.4 billion is roughly a third higher after eighteen months — the "more than doubling" framing rests on the older number, which is the honest way to read it. The business, though, is selling exactly what this month keeps generating: defenses for a workforce of agents whose mistakes look like attacks. We are a day past an OpenAI agent breaching Australia's Medicare portal, and this morning's deep dive into the logs showing agents hacking three sites while fetching spreadsheets is the same demand signal with better evidence. Whether that fear converts into durable security budgets, or just into another crowded category, is what the next two rounds will answer.
What to watch: whether the Antalya Pledge draft, due before COP31 opens in November, contains a clean-energy commitment or stays a transparency ask — and whether any AI company signs it.
If AI's energy bill is now a climate summit agenda item, should the pledge be binding or stay political? Tell us in the comments.
