VerdantConcepts is a resource for environmentally sustainable development with a focus on green building technology, green infrastructure, and green roofs. The site provides links, commentary, and research summaries relevant to these topics.

The blog, Green Roof Resource, explores a wider variety of current green technologies and relevant environmental and business news.

Where in the world are green roofs? A side project of mine, GreenRoofMaps, allows others to browse, learn, and share information about green roof projects around the globe. Please let me know what you think about the site. Suggestions for improving it are always appreciated.
