Amazon and Google Emissions Surge as AI Expansion Collides With Climate Goals

The artificial intelligence boom is creating a carbon problem for Big Tech. Amazon and Google both reported substantial emissions increases in 2025, underscoring the tension between rapid AI infrastructure buildout and corporate climate commitments.

Amazon's greenhouse gas emissions climbed 16% from 2024 to approximately 81 million metric tons of carbon dioxide equivalent—comparable to the annual emissions of 19 million gasoline-powered vehicles, according to a sustainability report the company released Wednesday. Google reported an 18% overall increase in what it terms "ambition-based" emissions, which exclude portions of its supply chain, with its direct operational emissions rising 20% year-over-year, the company disclosed Tuesday.

Why it matters

The emissions trajectory at two of the world's largest technology companies signals a fundamental conflict between AI ambitions and decarbonization targets. As these firms race to deploy generative AI capabilities that require massive computational resources, their carbon footprints are expanding even as net-zero deadlines approach. The trend has implications beyond corporate sustainability reports—it's driving new fossil fuel infrastructure investment and raising electricity costs, while activist investors and climate advocates question whether the industry's environmental commitments remain credible.

Data centers drive the increase

Both companies attributed their emissions growth primarily to data center expansion. Amazon cited construction activity and delivery fuel consumption as key drivers. Google pointed to its growing data center portfolio, with the company's electricity consumption jumping 37% in 2025.

The manufacturing and construction processes themselves carry substantial carbon costs. Google reported a 25% increase in supply-chain emissions from 2024, driven largely by hardware production and facility construction—activities that require energy-intensive materials like concrete and steel.

Clean energy gains can't keep pace

Google managed to reduce its emissions from purchased electricity slightly despite higher overall power consumption, crediting clean energy procurement. Amazon saw the opposite result, with emissions from electricity purchases rising 34%.

The disparity highlights what Google acknowledged in its report: AI infrastructure is scaling faster than the electrical grid is decarbonizing. Amazon has set a net-zero target for 2040, while Google aims for 2030.

Industry-wide challenge

Other major technology companies face similar pressures. Microsoft and Meta reported emissions increases of 23% and 64% respectively in their most recent disclosures, Bloomberg News first reported. Microsoft has reportedly considered scaling back its commitment to match 100% of hourly electricity consumption with zero-carbon energy by 2030 due to data center growth.

The power demands are spurring investment in natural gas plants and other fossil fuel infrastructure. SpaceX is operating AI data centers in Tennessee and Mississippi using gas turbines.

Criticism mounts

Sasha Luccioni, co-founder and chief scientific officer of Sustainable AI Group, argued the industry should be reducing emissions, not expanding them. "We're essentially in a climate crisis and we should not be having emissions growth at all, arguably, and yet the data centers are going in the opposite direction," Luccioni said.

Activist investors filed shareholder proposals this spring asking Amazon, Alphabet, and Meta to explain how they're reconciling AI electricity demand with climate commitments. None of the proposals received majority support.

Both Amazon and Google stated they remain committed to their sustainability goals. Amazon Chief Sustainability Officer Kara Hurst acknowledged in the company's report that while AI adoption is happening at unprecedented speed and scale, the company must stay focused on its vision while remaining flexible on execution details.
