Microsoft Buys $1.7B Poop Mountain, Buries Waste to Offset AI Smog

Microsoft’s $1.7 billion partnership with Vaulted Deep will see 4.9 million metric tons of manure, sewage, and agricultural byproducts injected 5,000 feet underground—a surreal answer to “Can human waste fight climate change?” and “How do tech giants offset AI carbon emissions?” Vaulted Deep’s CEO notes, “Generally, what happens to these wastes today is they go to a landfill, they get dumped in a waterway, or they’re just spread on land for the purpose of disposal.”
While most companies buy carbon credits, Microsoft’s approach involves massive waste slurries and a billion-dollar invoice. Vaulted Deep’s method—unique among carbon offset companies—transforms organic refuse into a subterranean paste, tackling queries like “What is the weirdest carbon offset?” and “How much pollution do AI data centers create?” Now, the world’s richest tech company literally shovels billions into the earth, while data centers hum above.
Microsoft’s underground poop stash will bury more waste by volume than the Great Pyramid of Giza, all to counter the invisible cloud emissions of its AI empire.
