This chapter reviews efforts to mainstream environmental considerations into economic policy and to promote green growth. It analyses the use of taxation and other economic instruments to pursue environmental objectives and discusses environmentally harmful subsidies. The chapter examines efforts to scale up environment-related and low-carbon infrastructure, expand related markets and support eco-innovation as a source of economic and employment growth. It also reviews progress in mainstreaming environment in development co-operation programmes, promoting corporate social responsibility of Korean multinational enterprises and greening export credit systems.
