12 GW

Contracted 12 GW of clean energy

Google is one of the largest corporate purchasers of clean energy in the world. We signed agreements to purchase over 12 GW of net-new clean energy in 2025the largest annual total in our history and more than our total procurement from the previous two years combined.1
58M

Avoided 58M tCOe across our operations and supply chain

In 2025 alone, initiatives like machine hardware efficiencies, software and compute efficiencies, and clean energy procurement collectively avoided over 58 million tCO2e.2
88%

Diverted 88% of data center waste

In 2025, we diverted 88% of our operational waste from disposal across our global Google-owned and -operated data centers.3
2B

Expanded flood forecasting to cover 2B people

Our flood forecasting information covers more than two billion people in around 150 countries for the most significant and impactful riverine flood events.4
78%

Replenished 78% of our total freshwater consumption

We increased our water stewardship portfolio to 165 projects5 spanning 97 watersheds, which replenished approximately 7.7 billion gallons of water in 2025 alone, roughly 78% of our 2025 total freshwater consumption.6
41M

Enabled 41 million tCOe emissions reductions through nine products

Nine of our solutionsincluding Google Earth, Nest thermostats, fuel-efficient routing in Google Maps, Solar API, and morehelped individuals, cities, and partners collectively reduce an estimated 41 million tCO2e in 2025.7

The total GW figure represents clean energy procured through power purchase agreements, energy storage agreements, and agreements under which Google receives environmental attribute certificates. Actual generation may vary from contracted amounts based on project modifications, terminations, and performance.
Avoided emissions are emissions that would have otherwise occurred but were avoided because of actions taken either as part of normal operations or in service of our climate ambitions. We calculate avoided emissions by comparing our actual emissions to a scenario where we didn't take action. To estimate aggregate avoided emissions, we first estimated annual avoided emissions across our carbon reduction initiatives and then combined the totals. For more details about these emissions, refer to the Avoided emissions section in the Detailed disclosures section of our 2026 Environmental Report.
For details about this calculation, refer to the Methodology section in the Detailed disclosures section of our 2026 Environmental Report.
The estimated population covered for significant events is as of July 2025, based on the forecasted flood risk area, using the WorldPop Global Project Population dataset. Significant flood events are events that meet a predetermined threshold based on an internal rating scheme that takes into account a number of factors.
The 2025 total of 165 projects reflects a net adjustment of -1 project from our 2024 year-end count. This project was removed due to pending scope and timing changes, but may be re-integrated into our portfolio in the future. This adjustment explains the variance between the 2024 total (112 projects), the 2025 additions (54 projects), and the 2025 portfolio total (165 projects).
For details about this calculation, refer to the Methodology section in the Detailed disclosures section of our 2026 Environmental Report.
To estimate aggregate enabled emissions reductions, we first estimate annual reductions for nine products individually (Google Earth, Nest thermostats, Solar API, Ignite Energy Access, fuel-efficient routing, Green Light, alternative route suggestions, Contrails, and Waymo) and then combine the totals. For details about the individual calculation methodologies, refer to the respective endnotes for each product solution in our 2026 Environmental Report. We continue to work to refine our methodologies and inputs for these estimates.
