Amazon’s AI expansion increased carbon emissions by 16%, intensifying the debate over whether rapid advances in artificial intelligence can coexist with ambitious corporate climate goals. According to Amazon’s latest 2025 Sustainability Report, the company’s total carbon footprint rose 16% year-over-year to nearly 80.9 million metric tons of CO₂ equivalent, largely driven by massive investments in AI infrastructure and new data centers. The increase comes despite Amazon’s commitment under its climate pledge to achieve net-zero carbon emissions by 2040.

While the company highlighted progress in renewable energy, electric vehicles, and data center efficiency, the surge in electricity demand from AI has emerged as one of the biggest challenges to reducing emissions across the technology sector.

AI Infrastructure Is Driving Higher Energy Demand

The biggest contributor to Amazon’s emissions growth was a sharp rise in electricity consumption. The company reported that its indirect emissions from purchased electricity increased by 34% in 2025, mainly because of expanding data centers, electrifying delivery operations, and increasing building electrification.

Artificial intelligence workloads require enormous computing power, with AI servers operating continuously to train and run increasingly sophisticated models. This has accelerated the construction of new data centers worldwide, significantly increasing electricity demand.

Sustainability Goals Face New Challenges

In the report, Amazon Chief Sustainability Officer Kara Hurst acknowledged that artificial intelligence has fundamentally changed the company’s sustainability landscape.

She noted that while AI has the potential to accelerate scientific discovery, optimize operations, and improve efficiency, it also creates unusual demand for energy, water, and infrastructure.

The company’s latest disclosures also showed an increase in its carbon intensity, the amount of carbon emitted relative to each dollar of revenue, for the first time since 2019. Amazon has previously used this metric to demonstrate that business growth could be separated from environmental impact, making the latest increase particularly significant.

Climate Advocates Raise Concerns

The rise in emissions has drawn criticism from Amazon Employees for Climate Justice, an employee advocacy group that argues the company’s climate commitments are being undermined by continued expansion.

According to the group, Amazon’s total emissions have increased by 58% since launching the Climate Pledge in 2019. Representatives say growing investments in AI infrastructure are outweighing many of the company’s environmental achievements and have called for stronger accountability in meeting climate targets.

Progress Continues in Renewable Energy and Efficiency

Despite rising emissions, Amazon also highlighted several areas where it continues to make environmental progress.

• The company says its cloud data centers are 9% more energy efficient than the public cloud industry average and 30% more efficient than traditional on-premises data centers at directing electricity toward computing rather than cooling and supporting infrastructure.
• Amazon also reported that its facilities are seven times more water efficient than the industry average, largely due to extensive use of air-cooling systems instead of water-intensive cooling technologies.
• For the third consecutive year, Amazon matched its global electricity consumption with an equivalent amount of purchased renewable energy.
• In transportation, the company now operates more than 52,700 electric delivery vans worldwide, placing it over halfway toward its target of deploying 100,000 electric vehicles by 2030.

What’s Ahead?

Although Amazon’s AI expansion increased carbon emissions by 16%, reflecting the environmental cost of rapidly scaling artificial intelligence infrastructure, the company maintains that renewable energy investments, more efficient data centers, cleaner logistics, and sustainable construction will continue to reduce its long-term climate impact.

However, the pace of AI expansion remains extraordinary. CEO Andy Jassy recently announced that Amazon expects to invest around $200 billion in capital expenditures this year, with a substantial share allocated to AI infrastructure, custom chips, robotics, and low-Earth-orbit satellites.

As global demand for AI computing continues to accelerate, Amazon’s experience illustrates one of the defining sustainability challenges facing the technology industry: balancing innovation and digital growth with meaningful reductions in greenhouse gas emissions.
