Green growth has been recognised as a key policy, as it can address economic growth, social inclusion and environmental sustainability at the same time. Especially, fostering green growth in cities is critical because cities play disproportionately large roles in the economic and environmental performance of countries (OECD, 2013) (Box 3.1). To do this it must catalyse investment and innovation which will underpin sustained growth and give rise to new economic opportunities” (OECD, 2011). The Global Green Growth Institute (GGGI) defines green growth as “a development approach that seeks to deliver economic growth that is both environmentally sustainable and socially inclusive” (GGGI, 2017).
