<p align="justify"> Roadside greenery is a lane located within the road space used for plant placement and other elements. As a unity of trees, roadside greenery functions as a buffer. Roadside greenery has three main functions: pollution reduction, noise absorption, and serving as roadblocks. As one unit, tree in urban areas have ecological functions as carbon sink and reducing motor vehicles pollution. However, due to the existing gap between CO2 emissions and CO2 absorption by trees, the function of roadside greenery in urban areas needed to be optimized. This study aims to measure the CO2 current absorption and carbon storage in roadside greenery. The study was conducted in Tegalega, a sub area of Bandung city. It is the densest area in Bandung. The data collection was done by census on five selected roads: Soekarno Hatta Road; Moch. Toha; Kopo; Terusan Pasirkoja; and Peta. Data from the trees on roadside greenery informed its species and diameter measurements. This is used to analyze CO2 uptake and carbon stores. Data collection was done by counting the number of vehicles per 15 minutes for 2 hours at the same location four times per day. Vehicles consisted of 13 types of motor vehicles. Tree data were analyzed based on the density per area, the diversity index with the Shannon-Wiener index, the amount of CO2 absorption, and the carbon stores that were calculated by allometric equations. The calculation of the emissions referred to the regulations from the Intergovernmental Panel on Climate Change in 2006. The results showed that the value of CO2 emission generated by the vehicle was 1,739,686,8 ton / year, while the absorption of CO2 was only 452,127 ton / year. This meant that the remaining CO2 emission was 1,739,234,74 ton / year. This value indicated that roadside greenery absorption of CO2 was not optimal. The carbon storage in roadside greenery of 443.56 tons indicated that roadside greenery stored large amounts of carbon for urban areas. Based on the value of CO2 emissions from vehicles, the absorption of CO2 and the remaining CO2 emissions, a strategy could be advised. This would involve adding 13 species of vegetation as much as 457,549 trees to roadside greenery and limitation of vehicles volume, up to 43,137 units / year. <p align="justify">
