Research reports – Advancing green purchasing in local governments

The Sustainable Purchasing Research Initiative is an international research partnership on sustainable purchasing. SPRI is leading a groundbreaking study on sustainable purchasing policies and initiatives in local governments. This innovative research conducts a global survey of city managers in decision-making positions to learn more about the successes and limitations of sustainable purchasing. This survey has now been implemented across municipalities in Australia, Italy, Japan, and Mexico. Our extensive reports will help you understand what works for local cities and municipalities that have implemented sustainable purchasing policies.
