A decade after it took form, the Clean Energy Program of the Asian Development Bank (ADB) was assessed according to the indicators set out in the 2009 Energy Policy. Drawing from hundreds of clean energy and energy access projects approved by ADB in 2008–2018, this review determines how far the bank has gone toward achieving its targets vis-à-vis baseline data from 2005 to 2007. It also explores what must to be done further in light of the new approach under ADB’s Strategy 2030 and the global goals in mitigating climate change and promoting sustainable development.
