This paper reports evaluation and planning of greenspace in the highlands region of Surabaya. Evaluation conducted by taking primary data related to the number of vehicles with traffic counting method and secondary data in the form of population, vegetation type, and pattern of greenspace vegetation planting. The calculation of the adequacy of greenspace is done by calculating the volume of carbon dioxide emissions by humans and vehicles. The calculation is then multiplied by the emission factor. In addition, it calculates absorption capacity of total carbon dioxide from the existing greenspace vegetation. The results showed that the existing vegetation could be preserved and enriched with the addition of vegetation species to absorb carbon dioxide gas emissions and in accordance with the laws and regulations.
