Estimación de la compensación de CO2 del arbolado urbano respecto las emisiones vehiculares del tránsito de motocicletas en el separador vial del estado macal, cr 19 entre calles 23ª 25, villavicencio

Abstract

Environmental compensation is a way of counteracting the adverse effects of non-avoidable situations, such as atmospheric emissions by motorcycles; this work sets out the estimate of this compensation of the road separator against the Villavicencio’s MACAL stadium.

Initially, the dasometric characteristics of urban woodland were analyzed, starting from nondestructive methods that ensured the conservation of study area; for this, fields measurements were taken such as diameter at breast height, stem height, total height, leaf type, growth habit, among other parameters that were arranged in allometric equations to obtain, theoretically, the total carbon stored in the separator, which corresponded to: 338,98 Ton CO2/year.

Following this, it was estimated the amount of CO2 in Ton/day of the average of motorcycles traveling at peak time (5:40 p.m. – 6:40 p.m.) for 10 days using the International Vehicle Emissions Model (IVE); the data required for modelling were: classification of motorcycles (light, medium, heavy), type of engine (2 times or 4 times), type of fuel (petrol), average speed, acceleration, among other data taken in field measurements, resulting in a total of 1409,6 Ton of CO2 emitted per year.

Finally, carbon storage was related to the amount of emissions from motorcycles travelling in the sector, to be projected in a model of 10 years that started from population growth indices and motorcycle indices per habitant in Villavicencio, the result showed a deficit in the compensation of emissions, in the first year of study alone, 76% of the CO2 emitted needs to be fixed, therefore, an analysis is made of possible solutions to reduce this percentage.
