Various programs that aim to minimize air and noise pollution from the transport sector are being implemented. These programs are usually conducted in areas with large and dense population or areas where flow of traffic and people are heavy. The aim is to improve air quality via the application of command and control schemes or market based instruments in the transport sector. Interventions could also involve introduction of alternative technologies (e.g. electric buses) or arrangements (e.g. limitation on number of vehicles via coding schemes). The case of Palawan showcases possible preventive interventions that can be put into place. It also makes a point that preventive interventions are effective and could even be less costly to undertake.
