A study of CO

Global climate change has prompted the Government of the Republic of Indonesia to commit to an active role and participation in the attempt of reducing Greenhouse Gas (GRK) emission through a national action program. One of the biggest sectors contributing in the production of GRK is transportation. Meanwhile, the condition of roads also affect the speed of vehicles. This study analyzed the relationship between road condition and travel speed, and the resulting CO2 emission. This research was conducted by taking some class III roads in Brebes as samples. The stages of this study include assessing the road condition by using the PCI method, calculating the average speed of vehicle on each sample road, and from the data of travel speed, the value of CO2 emission was then calculated using IPCC method. The result of this study indicated that the road condition is the factor that affects the travel speed. Increasing the value of PCI by 10 points from the lowest value will reduce CO2 emissions by 3.36% for gasoline-fueled vehicles. This research suggests improving the road condition in Brebes district in order to support Local Action Plan for Greenhouse Gas Emissions Reduction
