Facebook has launched its Greenbook application to help reduce CO2 emissions emitted by its servers and millions of worldwide users.

Basically what the Greenbook add-on does is generate money through sponsorship. The money collected through these sponsorships are then used to fund emission reducing efforts. Facebook will be using the money to invest in renewable energy sources such as solar and wind power.

In other words, the more users download the app, the more the funding these efforts will receive.

So, the next time you log onto Facebook and socialise, you could simultaneously be helping the global environment.
