Carbon stock and carbon emission estimation in Java's North Coast National Road (Jalur Pantura) within Karawang Regency using high resolution satellite image

Java's North Coast National Road also known as Jalur Pantura is a primary transportation corridor connecting Indonesian capital city of Jakarta and eastern part of Java Island. Interestingly, the road's greenbelt is located in Karawang Regency planted with various trees. From its diameter breast height (DBH) and height, above ground biomass (ABG) from these trees were estimated and then compared with four vegetation indices namely NDVI, SAVI, EVI and tasseled cap extracted from SPOT-7 satellite image. Furthermore, this study used predicted ABG values to generate carbon stock and carbon absorption ability. In addition, data from daily vehicle traffic observation will be employed to predict carbon emission. Estimated vehicle carbon emission then compared with carbon absorption ability for each road segment to observe how big trees can store carbon emission from vehicle. The information of carbon balance in each road segment, in form of comparison between carbon absorption ability with vehicle carbon emission, can be useful for road authority to increase vegetation especially in the areas of low carbon absorption.
