I am a Senior Manager for Campaigning at co2online.
co2online, a German non-profit company, has campaigned since 2003 for energy efficiency and climate protection. During this period co2online has developed online campaigns, projects and action programmes, funded by government or EU grants. Their common purpose is to inform consumers on an individual basis about an energy-efficient lifestyle and to encourage them to take further action. co2online focuses on dialogue by means of interactive advisory services and implements web 2.0 tools, social media communication and mobile applications successfully.
I was asked to post about a so called "green search engine" on this forum: www.ecosia.org
Their website is a co-operation with WWF, every click on a sponsored link generates a donation for a rainforest project. In addition, Ecosia offsets the CO2 emissions of all searches.
