Mountain View, September 11 — Google’s own environmental report, published on its sustainability website, shows the company’s greenhouse gas emissions climbed to 14.3 million metric tons of carbon dioxide equivalent in 2023. That is a 48 percent jump over its 2019 baseline of 9.7 million metric tons, and a 13 percent rise over 2022, when emissions stood at 12.6 million metric tons.
Google attributes the increase mainly to the electricity demands of data centers running artificial intelligence products, including the Gemini AI model, and to the expansion of its cloud computing infrastructure. The report also acknowledges that folding AI into more of its products could make cutting emissions harder, because the energy intensity of AI computing is higher than that of traditional search or cloud workloads.
The electricity bill behind the numbers
Data center electricity consumption rose 17 percent in 2023. Total electricity use reached 24 terawatt-hours, with roughly 64 percent of that coming from carbon-free sources such as wind and solar. Water consumption, driven by data center cooling, also rose 17 percent, to 6.1 billion gallons.
Google set a goal in 2020 of reaching net-zero emissions across its operations and value chain by 2030. That target covers Scope 1, Scope 2 and Scope 3 emissions, and the company says the bulk of its carbon footprint comes from Scope 3 sources — purchased goods and services, capital goods, and upstream transportation.
The company has invested in carbon removal credits and renewable energy projects, including power purchase agreements totaling more than 10 gigawatts of clean energy capacity.
An industry-wide pattern
Google is not alone in this. Microsoft has reported a 29 percent increase in emissions since 2020, and Amazon has faced criticism over its own climate commitments. The disclosure arrives as regulators in the United States and Europe step up scrutiny of AI’s environmental impact, with the European Union’s AI Act including provisions for transparency and energy reporting.
Google CEO Sundar Pichai has said AI can help address climate change by optimizing energy grids and improving forecasting. The company’s own data shows that scaling AI is currently increasing its carbon footprint.
Alphabet, Google’s parent company, reported 2023 revenue of $307.4 billion. The practical upshot for readers is straightforward. The same AI tools that companies are racing to build carry a measurable energy cost, and Google’s numbers show that cost landing on its climate ledger.
Watch whether the company’s next environmental report shows the curve bending back toward its 2030 target, or whether AI’s power demand keeps pushing it the other way.
