Ecosia

Ecosia lets users plant trees by searching the web. In donating 80 percent of its surplus ad revenue, the search engine has raised over $3 million for rainforest protection and reforestation since its founding in December 2009. Ecosia's mission to cultivate a world where the environment doesn’t need protecting has it working to plant one billion new trees by the year 2020. By supporting high-impact reforestation efforts – as well as neutralising all CO2 emissions related to its search – Ecosia aims to achieve the highest positive environmental impact per dollar possible. By publishing its monthly donation receipts online, Ecosia aims to live up to its users’ demands for transparency. And by working to improve its charitable web service day after day, Ecosia aims to show the world that small changes can make a big difference. Learn more: https://www.ecosia.org/what
