This document discusses green and sustainable infrastructure (GSI) and the opportunities it presents. GSI parallels the development of green buildings in using innovation to meet owner/investor demands for tangible/intangible returns. Like green buildings, GSI is attracting early investors and will likely mature over 10-15 years. The US faces a large infrastructure funding gap, creating opportunities for private partnerships to deliver more cost-effective GSI projects that provide multiple benefits. Demand is growing from government and private sectors for sustainable infrastructure solutions.
