Cuantificación de la huella de carbono aplicando la norma iso 14064-2019, de la zona del páramo de las abras, microcuenca alta del río mocha y páramo de guargualla.

Abstract

The aim of the current research was to quantify the Carbon Footprint, applying the ISO 14064-2019 Standard, in the paramo areas of las Abras, the upper micro-basin of the Mocha River and the Guarguallá paramo, areas with a great incidence of agricultural and livestock activities. A baseline survey was carried out, covering physical, biological and socioeconomic factors and determining the factors for the Environmental Impact Assessment (EIA), based on the Modified Leopold methodology. For the physical, physical-chemical and chemical analysis, eight soil samples were randomly taken under accessibility criteria and ensuring the representativeness of the soil and plant matter samples. After the EIA, these negative values were obtained: -3681 in the Upper Micro-basin of Mocha River, -3899 in las Abras paramo and -4077 in the Guarguallá paramo; based on these data, surveys for three sections were conducted: agrochemical use, fuel use, and energy consumption; to apply the formula established by the ISO 14064- 2019 standard with the following results: a total emission of 1 723.41 tons of CO2 eq emitted to the atmosphere, agricultural activities generate 163.22 tons of CO2eq, the use of fuel emits 1 558 tons of CO2eq and the use of electricity emits 441.74 tons of CO2 eq, according to analysis carried out in the laboratory, the amount of oxidizable carbon found in the soil is higher than 4% and the amount of organic matter values is higher than 8%; Heavy metals (Cd, Ni, Pb, Hg, Cr, and As), do not exceed the maximum permissible limits; consequently, soils are the precursors in receiving the amount of CO2 emitted into the atmosphere, fixing carbon into the soil and releasing oxygen.
