Evaluation of the Shape of Tree Crowns to protect Air Quality on the Roadside from the CO<sub>2</sub> Dispersion produced by Transportation

Abstract

This research focuses on evaluating the shape of a tree's crown and its impact on CO2 dispersion from transportation. CO2 emissions from motor vehicles can quickly spread and cause poor air quality on the roadside. The design of tree planting is a way to control air quality by reducing CO2 dispersion. Therefore, the tree's crown shape is an essential element to consider when planting trees, as different crown shapes can have different effects on CO2 dispersion. Selecting the wrong shape for a tree's crown can have negative consequences for controlling CO2 dispersion on the roadside.
