'Green Atlas', an online-only compendium of 100 maps and data sets accompanied by multimedia elements designed to illustrate key concepts in green issues and environmentalism graphically and interactively. This will be a 'capstone' volume, in atlas format, for the SAGE Reference Series on Green Society, a series of 12 single-volume, electronic-only reference works. Topics for the maps presented in this capstone volume will be selected from the approximately 1,800 articles in the twelve preceding volumes. Each map will include links to one or more Green Society articles. Further, multimedia elements will accompany map themes and presentations. The maps will include clickable links that will deliver other components like video, articles, etc. that will offer more related information on that topic.
