Google Environmental Report 2018
Google has been carbon neutral for over a decade and in 2017 we purchased enough renewable energy to match 100 percent of our global consumption for operations.
View full PDF(opens in a new window)Operating our business in an environmentally sustainable way has always been a core value. We think there’s a lot to be proud of—but there’s also a lot more important work to do. We remain more committed than ever to the environment and will continue working hard for a cleaner, and better future for the generations to come.
This report contains data and information valid as of December 31, 2017.
Efficient data centers help us better serve our users, in a more sustainable way.
For more than a decade, we’ve worked to make Google data centers some of the most efficient in the world, improving their environmental performance even as demand for our products has dramatically risen. We’ve done this by designing, building, and operating each one to maximize efficient use of energy, water, and materials.
Squeezing more out of every watt.
To reduce energy use, we strive to build the world’s most energy-efficient computing network by squeezing more out of every watt of power we consume.
And our efforts have paid off: on average, a Google data center uses 50% less energy than a typical data center. One aspect of our efficient designs is PUE.

These peaks happen in the summertime when additional energy is needed to cool the data centers.
-
Our fleet-wide PUE has stayed at or below 1.12 since 2013.
In 2017, the average annual PUE for our global fleet of data centers was 1.11, compared with the industry average of 1.7—meaning our data centers use nearly six times less overhead energy. -
The data center industry uses the measurement PUE, or power usage effectiveness, to measure efficiency. A PUE of 2.0 means that for every watt of IT power, an additional watt is consumed to cool and distribute power to the IT equipment. A PUE closer to 1.0 means nearly all of the energy is used for computing.

Certifiably smart energy management.
You can trust we’re using energy wisely, because Google was the first company in North America to achieve a multi-site ISO 50001 certified energy management system. In 2017, our ISO certification (which verifies we’re working to continually improve our energy efficiency) covered 12 Google-owned data centers, representing more than 96% of our IT energy use.
Helping technology live a long, productive life.
We’re committed to achieving Zero Waste to Landfill for our data center operations. We’re working towards this by reducing the amount of waste we generate by doing things like refurbishing and remanufacturing hardware, and reducing the amount of waste we generate, and finding better disposal options—like recycling and reselling.
In 2017, we diverted 91% of waste from our global data center operations away from landfills.

Accelerating the transition to renewable energy.
We’ve made it a top priority not only to become more energy efficient, but also to ensure that the energy we purchase comes from clean sources such as renewables. Our support for clean energy goes hand in hand with reducing our carbon footprint. By improving the efficiency of our operations and buying both renewable power and high-quality carbon offsets, we’ve been carbon neutral since 2007.
-
2007
We committed to carbon neutrality and purchased enough carbon offsets to bring our net annual emissions to zero for the first time.
At our Bay Area headquarters, we installed a 1.6 megawatt (MW) rooftop solar installation—the largest corporate solar array at the time.
-
2010
We made our first purchase of renewable energy for our operations by signing a 20-year power purchase agreement (PPA) with the Story County II wind farm in Iowa.
We also began contributing to growing the clean energy market by making our first renewable energy equity investment with a $39 million commitment to the 170 MW Peace Garden wind farm in North Dakota.
-
2014
We surpassed a cumulative total of 1 GW of renewable energy purchased for our operations.
-
2015
Our cumulative commitments reached $2.5 billion in renewable energy equity investments.
-
2016
We signed PPAs for 564 MW of renewable energy, bringing us to a cumulative total of 20 PPAs for more than 2.6GW of renewable energy.
-
2017
We reached 10 consecutive years of carbon neutrality and have purchased enough renewable energy in 2017 to match 100% of our global consumption for operations.
Google is the world’s largest corporate purchaser of renewable energy.
Since 2010, we’ve signed 26 agreements to purchase nearly 3GW of new renewable energy. (That’s like taking more than 1.3 million cars off the road per year). And in 2017, we reached 100% renewable energy for our operations.
