The Urban Sustainability Assessment (USA) Project  involves developing and testing a protocol for systematically evaluating the effectiveness of urban sustainability programs in the United States. This project is yielding several sample assessments—on composting , urban agriculture, tree planting, and light rail—as well as a protocol that academic or consulting teams can use to develop their own assessments.
The first report, Municipal Curbside Compostables Collection: What Works and Why?  can be accessed for free via the link on the left of the page under downloads. Please also take a moment to complete our very brief survey  to facilitate a more targeted and benefical report.
