EDN - Earth Day Network
Founded by the organizers of the first Earth Day in 1970, Earth Day Network (EDN) promotes environmental citizenship and year round progressive action worldwide. Their mission is to broaden the environmental movement worldwide and to educate, by calculation of their Ecological Footprint through the personal calculator, and mobilize people, governments, and corporations to take responsibility for a clean and healthy environment.
Through EDN, activists connect, interact, and impact their communities, and create positive change in local, national, and global policies. EDN's international network reaches over 12,000 organizations in 174 countries, while the domestic program keeps over 3,000 groups and over 100,000 educators coordinating millions of community development and environmental protection activities throughout the year. As a result, Earth Day is the only event celebrated simultaneously around the globe by people of all backgrounds, faiths and nationalities. More than a half billion people participate in their campaigns every year.
