A new search engine launching today is promising to give at least 80 percent of revenues to the World Wildlife Fund (WWF) to protect rainforests.
Ecosia has been founded by a group of green-minded friends in Berlin concerned that more than half the world's rainforests have been destroyed in the past 50 years.
Powered by Yahoo and Bing, the site promises users that each click on a sponsored link will save two square metres of rainforest in Brazil's Juruena-Apui region.
"Every year billions of dollars are being earned in the internet only from advertising revenue," says Christian Kroll, founder of Ecosia. "There is a more eco-friendly way of using these huge profits: the money should better be used to fight global warming.
"If only one percent of global internet users accessed Ecosia for their web searches, we could conserve a rainforest area as big as Switzerland every year."
The company has dotted its 'i's and dotted its 't's: Ecosia servers use 'eco-electricity' from sustainable sources. The company says it will scrap all user data after 48 hours and not mine it for marketing purposes.
