Environmental Benefits Report of GPR Projects

Environmentally innovative projects under the ARRA GPR provision have not previously been included in the EPA’s previous reports. This was due to significant project variances within these categories, which could not objectively be measured. This summary report provides an overview of the data collection efforts, assumptions and methodologies, research limitations, and results found in the comprehensive report. Subcategories under the three categories for sustainable improvement have been made, spread to project managers, and used to facilitate quantifiable environmental benefit analysis. On average, each energy efficiency project is estimated to save 4 million gallons of water, water efficiency projects save over $1 million per year, and each green infrastructure project to reduce stormwater runoff by 22 million gallons. Projects vary vastly by size and type, and are hard to draw generalizations or absolute conclusions from, but are vaguely useful to determine benefits of work done and facilitate future funding priorities.
