The provision of green open space (RTH) is one of the most implementing mitigation efforts for climate change compared to other ways. The purpose of this research is to (1) identify the diversity of types of RTH components plants in the city of Surakarta, (2) estimate the potential for storage of biomass and carbon, (3) estimate the potential for absorption of carbon dioxide gas, and (4) estimate the economic value of the absorption of carbon-dioxide from open space components on the open space in the forest of the City of Surakarta.
This study uses primary and secondary data. Field samples are obtained by calculating the number of sample points based on the Fitzpatrick formula. The data taken at the time of the inventory included the type of tree, the diameter of a tree as high as the chest (DBH), the height of the tree, and the number of trees. Other data such as the general conditions of the research site, RTH distribution map, Shapefile administrative boundaries and land use as well as Wood Density data of each type of inventory results.

The results of this study showed that ten types of plants dominate the green open space of the forest park of Surakarta City: Samanea saman, Mangifera indica, Pterocarpus indicus, Tectona grandis, Swietenia mahagoni, Polyalthia longifolia,  Kigellia pinnata, Casuarina equisetifolia, Terminalia mantaly, and Terminalia catappa, has an Shanon Wiener (H’) diversity index value of 3.317. The biomass, carbon, and carbon dioxide absorption  potential of the plant component of the forest park of the City of Surakarta are consecutive; 870.03 tons of biomass/ha, 408.91 tons of carbon/ha, and 1,499.48 tons of CO2/ha. Based on the absorption of CO2, the economic value of the total area of the green open space in the forest city of  Surakarta can be estimated at Rp.4.761.437.794,26. This economic value gives the Surakarta City Regional Government an opportunity in world carbon trade.
