This study takes a close look at Korea’s state-of-the-art Green Public Procurement policy impact measurement methodology, with an overview of other successful international experiences. It makes recommendations on possible innovations to public procurement policy and measuring its impact, and presents an alternative approach to measuring the creation of green jobs and extending impact measurement to energy efficient labelled products. It examines the contribution that a macroeconomic assessment of impacts, based on a computable general equilibrium model, could make to understanding future policy options and scenarios in Korea.
