Urban parks form the largest proportion of public green spaces contributing to both physical and mental well-being of people living in urban areas. CO2 sequestration capability of the vegetation developing in parks of four historical residences (Villa Pamphjli, Villa Ada Savoia, Villa Borghese and Villa Torlonia) in Rome and its economic value were analyzed. Villa Pamphjli and Villa Ada Savoia having a larger vegetation extension (165.04ha and 134.33ha, respectively), also had a larger total yearly CO2 sequestration per hectare (CS) (780MgCO2ha−1year−1 and 998MgCO2ha−1year−1, respectively) than Villa Borghese (664MgCO2ha−1year−1) and Villa Torlonia (755MgCO2ha−1year−1), which had a lower vegetation extension (56.72ha and 9.70ha, respectively). CS was significantly correlated with leaf area index (LAI). The calculated CS for the four parks (3197MgCO2ha−1year−1), corresponding to 3.6% of the total greenhouse gas emissions of Rome for 2010, resulted in an annual economic value of $ 23537 /ha.
