Part of a series of reports published by The Inquiry into a Sustainable Global Financial System in mid-November 2017, the Singapore-based DBS digital bank reports that annual ASEAN green investment needs to grow 400% to guard against climate and environmental risks. The Green Finance Opportunities in Asian report by DBS and the UN Environment Inquiry signaled that USD 3 trillion in green investment is needed up to 2030, a new ASEAN green investment market 37 times the size of the global 2016 green bond market. Current annual ASEAN flows of green finance are estimated at USD 40 billion, against an average annual need of roughly USD 200 billion up to 2030. This investment is spread across infrastructure (USD 1,800 billion), renewable energy (USD 400 billion), energy efficiency (USD 400 billion) and food, agriculture and land use (USD 400 billion). Indonesia will require the largest volume of green finance.
