Facebook 2011 Carbon Footprint

Facebook shared its 2011 carbon footprint, energy mix and energy use for data centers and global offices.

"We're releasing this data because we believe in the power of openness, and because we hope that adding another data point to our collective understanding of our industry's environmental impact will help us all keep improving," Facebook said.

"The total annual carbon footprint per monthly active Facebook user is 269 grams."

Here are the numbers for 2011:

  • "Facebook's total energy use from office space, data centers and other facilities was approximately 532 million kWh.

  • Facebook's greenhouse gas emissions--also known as our carbon footprint--from data centers, office space, employee commuting, employee air travel, data center construction and server transportation totaled approximately 285,000 metric tonnes of CO2e (carbon dioxide equivalent, which includes greenhouse gases CO2, CH4, N2O, and HFCs).
  • Facebook's energy mix was 23% clean and renewable, 27% coal, 17% natural gas, 13% nuclear and 20% uncategorized (energy that's purchased by utilities on the spot market and can include any or all of the above categories)."

Facebook says, they will continue trying to introduce more clean and renewable energy into the mix that powers its data centers by:

  • "Including a preference for locations that have access to clean and renewable energy sources in our data center siting policy;
  • Engaging with environmental organizations, our industry peers and our utility providers to advocate for more clean and renewable energy sources in the overall energy mix available to all consumers;
  • Including a renewable energy component to every new data center we build so we can learn more about what such investments mean for Facebook. The small solar installation at our Prineville data center is a good example of the kinds of projects we'll undertake," Facebook informed.

"We also know that there is great opportunity in the power of our platform and the more than 950 million people who use Facebook. Through our facebook.com/green page and investment in partnerships, we are aiming to drive environmental awareness, education and action," the company said.
