This study quantified the carbon stock in the aboveground biomass of Suchiche Park (Tarapoto, Peru), a 0.265 ha urban green space. Using systematic sampling across 8 circular plots (100 m² each), 88 trees (DBH ≥ 10 cm) from 10 species were evaluated through non-destructive methods and validated allometric equations for tropical forests. Results revealed Elaeis guineensis (African Oil Palm) as the most efficient species, storing 10.76 Mg C (65.19% of the total) despite comprising only 26% of individuals. Its superiority was attributed to large size (mean DBH: 51.71 cm; height: 13.35 m) and high wood density, capturing 0.47 Mg C/tree (17× more than the second-most efficient species). The native Tarapotus Palm, while the most abundant (25 individuals), showed lower individual capture (0.15 Mg C/tree), contributing 22.2% of total carbon. Species like Ficus benjamina (17 individuals) had low efficiency (0.03 Mg C/tree) due to frequent pruning and reduced height (4.51 m). Significant correlations were found between dasometric variables and carbon: DBH vs. carbon (r = 0.93) and height vs. carbon (r = 0.88), confirming that each additional cm of DBH increases ~0.02 Mg C/tree. The park stores 16.51 Mg C (equivalent to 60.57 Mg CO₂), with a density of 62.2 Mg C/ha, surpassing urban areas like Northern Lima but still below primary Amazonian forests.
