Calculation of carbon sequestered through remote sensing in a metropolitan park in the city of Quito, Ecuador

Researchers have quantified the carbon sequestration potential of eucalyptus trees in Quito, Ecuador's Guangüiltagua Metropolitan Park, estimating that these trees store approximately 42,150 tons of CO₂. This finding was derived using a multi-phase approach combining remote sensing and field measurements. The study employed the Normalized Differential Vegetation Index (NDVI) from Landsat 8 and Sentinel-2 satellite imagery to assess vegetation health and biomass over time. Field data, including diameter at breast height (DBH) and tree height, were collected across 50 quadrants to validate and refine these estimates. Linear regression models then extrapolated the CO₂ storage per quadrant to the entire park area. This work provides critical data for urban carbon inventory initiatives, offering a scalable method for assessing carbon sequestration in metropolitan green spaces.
