Microsoft is investing billions to expand its AI capabilities, but there’s a big question hanging over its environmental plans. The company aims to be carbon-negative by 2030, meaning it wants to remove more carbon from the air than it emits. At the same time, it’s pouring $80 billion into building new data centers to power its AI projects. This creates a tricky balance—how can it grow so fast without worsening climate change?

AI Data Centers and Their Heavy Energy Use

The push for AI has led to the creation of massive data centers across the US. These centers require a ton of electricity, much more than typical data facilities. In fact, a recent analysis found that AI-focused data centers use 48% more carbon-intensive electricity than the national average. By 2026, US data centers could be the fifth biggest energy consumers worldwide, right behind Japan and ahead of Russia—if they were a country, they’d be a major energy hog.

Microsoft is not holding back. It plans to spend a huge chunk of money over the next three years to build and upgrade its infrastructure. This aggressive expansion is essential for its AI ambitions but raises concerns about the environmental footprint. The company has publicly committed to being carbon-negative by 2030, which means it plans to remove more carbon than it emits. The question is whether it can do that while also burning so much energy.

Relying on Carbon Offsets to Achieve Climate Goals

To offset its massive electricity consumption, Microsoft is turning to carbon removal credits. Instead of solely reducing emissions directly, it is investing in projects that suck carbon out of the atmosphere. One of its latest deals involves a company called Vaulted Deep, which plans to bury nearly 5 million tons of biowaste slurry deep underground. This slurry includes human waste, farm manure, and sludge from paper mills. The idea is that by burying this waste, it won’t decompose and release greenhouse gases like methane or CO2.

Microsoft has agreed to buy these credits over 12 years, spending around $1.75 billion. The credits are sold at about $350 per metric ton. This isn’t the only offset project Microsoft is involved in; it also invests in direct air capture and carbon sequestration initiatives. The company claims it won’t be engaging in “greenwashing,” a term for misleading claims about being environmentally friendly.

However, critics raise concerns about the technology behind these offsets. The deep well injection used by Vaulted Deep has been linked to risks like groundwater contamination, earthquakes, and surface leaks. Some experts argue that relying on offsets can be problematic, as they might not be as effective or permanent as promised.

Is Greenwashing a Real Threat?

Some experts are skeptical about the effectiveness of these offset projects. David Keith, a climate scientist at the University of Chicago, calls much of the voluntary offset work “greenwashing.” He argues that relying on companies’ promises to be green isn’t enough. Instead, he suggests stricter laws and regulations are needed to control emissions directly. Unfortunately, current political trends threaten such regulations; the EPA has been rolling back climate rules, and plans are underway to make it easier to build new data centers with fewer environmental hurdles.

This political climate makes it hard to trust that big tech companies will truly do what’s best for the planet. For now, Microsoft’s efforts are a sign of good intent, but whether they will be enough remains uncertain. The company’s investments in carbon removal are promising, but the real proof will be in how transparent and effective these projects turn out to be.

In the end, it’s a complex balancing act. Growing AI and data infrastructure can’t come at the expense of a healthy planet. As consumers and observers, we need to keep a close eye on how these commitments play out in reality. Holding companies accountable and demanding genuine transparency will be key to ensuring their climate promises aren’t just words.
