In an effort to further reduce greenhouse gas emissions from the transport sector, the Philippines' Clean Technology Fund Investment Plan (CTFIP) has formulated a program called National Environmentally Sustainable. Transport Strategy (NESTS) (CTFIP, November 2009). The overall goal of this program is to reduce "the annual growth rate of energy consumption and associated GHG emissions from the transport sector in the urban areas in the country and to mainstream environmentally sustainable transport which involves the promotion of lowcarbon intensity transport systems". This will promote, among other things, the development of the Bus Rapid Transit (BRT) system, expansion of the existing urban rail network in Metro Manila, deployment of hybrid vehicles in the public transport, and fuel switching in public transportation.
