Facebook launched an official "Green" page yesterday, highlighting what they're doing to be greener - from energy efficiency measures in their data centres, to auto/dual flush toilets in their offices.

Those efforts are all good, but we expect better from the internet heavyweight. We want to see Facebook announce a plan to drop coal power, and use and promote renewable energy instead.

Seasoned technology journalists and bloggers weren't buying it either. Under the headline "Facebook Kicks Off a Weak Green Offensive" writes Ucilia Wang on GigaOM: "We’ve said it before and we’ll say it again - Facebook can do more and be a leader in using renewable energy and in the process making it cheaper for others as well."

Meanwhile in Paris yesterday the international edition of The New York Times ran an article about our Facebook coal campaign, proving that the internet company's subject-changing tactics aren't working. 

Over 600,000 people, almost all of them members of Facebook, have joined our campaign since February calling on the company to go green. You can still get involved and engage with the company to support renewable energy instead of coal -- join the campaign here.

Facebook's new green page concludes "We only have one planet. Let’s do all we can to protect it". Hopefully the page, and the energy-saving initiatives it describes, is a sign that the company is beginning to seriously consider its environmental impact - not only cost-saving measures. But when - and why not?! - will Facebook commit to stop using polluting coal power?

Join our campaign, and spread the word!

Other cloud-based companies face similar choices and challenges as Facebook does in building data centres, yet many are making smarter and cleaner investments. Google, for instance, entered into a long-term agreement with a large wind power producer this summer. It has demonstrated that it is not only possible to prioritize the purchase of clean energy, but prudent as well.
