an optimization model for utilizing green road corridors and urban parks to enhance tree absorption of motor vehicle co2 emissions in pekanbaru city, indonesia

The surge in co2 emissions from vehicles has precipitated a rise in global temperatures, instigating the greenhouse effect. this study draws on case studies from prominent indonesian cities, including jakarta, surabaya, and manado, highlighting a notable dissonance between the capacity of plants to absorb carbon and the volume emitted. green road corridors and urban forests assume multifaceted roles in urban ecosystems, functioning as barriers, filters, absorbers, and producers, contributing to air quality, noise reduction, and environmental preservation. employing linear programming as a mathematical programming branch, this research integrates diverse factors into decision-making models. it strives to achieve optimal solutions pertaining to the selection and quantity of trees for maximizing co2 absorption resulting from motor vehicle activities in pekanbaru city, specifically along subrantas street and harapan raya street. land cover classifications in pekanbaru city encompass green spaces, buildings, open areas, undergrowth, water bodies, and non-private zones. the optimization model, targeting 10% utilization of the jalan subrantas urban park area, demonstrates a significant co2 absorption of 827,976 tons/ha and an o2 surplus of 176,207.72 tons/ha. conversely, full utilization of the jalan sudirman urban park area yields a co2 absorption of 206,982 tons/ha and an o2 surplus of 9036.63 tons/ha. these optimized outcomes lay a foundation for potential carbon tax development within the urban transportation sector of pekanbaru, with envisaged implementation by the year 2040.
