Google have just launched “Chrome for a Cause” – a Chrome browser extension that converts your web browsing into real donations to real charities. It tracks the number of tabs you open and at the end of each day it lets you choose which charity you want to donate to, based on your tab usage.

From TechCrunch:

The charities involved in this are: The Nature Conservancy, charity: water, Doctors Without Borders, Un Techo para mi Pais, and Room to Read. Here’s Google’s breakdown of how much you have to browse to donate to the various charities:

§ 10 tabs = 1 tree planted

§ 10 tabs = 1 book published and donated

§ 25 tabs = 1 vaccination treatment provided

§ 100 tabs = 1 square foot of shelter built

§ 200 tabs = 1 person’s clean water for a year

The initiative will run for five days from December 15 to the 19. Google says they’ll donate up to a million dollars on behalf of the extension’s users.

Only 3 days left, so install the extension and start browsing!
