In 2013, PPIAF, in collaboration with the World Bank Sustainable Urban Energy and Emissions Planning (SUEEP1) program in the East Asia and Pacifi c (EAP) Region, supported Da Nang in developing a long-term sustainable energy and emissions plan. The SUEEP program aims to promote solutions that would help de-link high levels of carbon-intensive energy use from urban growth in the EAP region. This collaboration helped establish the process to identify and prioritize green infrastructure investment opportunities to attract private-sector participation.
