Emerald cities [by Joan Fitzgerald] examines how American cities excel in sustainability - economic development : reviewed by Warren Nevad

Cities are major sources of pollution but because of their population density, reliance on public transportation, and other factors, Fitzgerald argues that they are uniquely suited to promote and benefit from green economic development. For cities facing worsening budget constraints, investing in high-paying green jobs in renewable energy technology, construction, manufacturing, recycling, and other fields will solve two problems at once, sparking economic growth while at the same time dramatically improving quality of life.
