Green Map System provides an award-winning iconography, adaptable framework, and social mapping platform that help people chart and promote sustainability in their own city. They support a locally-led community mapping movement that started in 1992 with a Green Map of New York City and spread to 65 countries through the work of Green Map Makers that are committed to inclusive participation and local livability in their home communities. Together, they have co-designed 170 Green Map Icons that can be used to identify local ecological, cultural, sustainability, and social justice sites on the Open Green Map platform or on other online mapping platforms. Services and resources are under a Creative Commons license and available at no cost to non-commercial users including educators, nonprofits, local governments, and grassroots community groups. Green Map System is a 501(c)3 not-for-profit organization that maintains these resources and offers tours, talks, and consulting services. They are part of O2 Global Network on Sustainable Design, the New Economy Coalition, and LES Ready.
