IISD and the Partnership for Procurement and Green Growth conducted an investigation to explore the correlation between public procurement and the tipping point at which it serves as a trigger for green industrial innovation, expansion and growth. Building on the existing body of work that supports the case for green public procurement, the report demonstrates that procurement is becoming more than just a purchasing tool, but is increasingly positioned as an economic driver, an incentive for green innovation and green industrialisation, a support for small and medium enterprise (SME) competitiveness and much more.
