Environmental protection was a key focus throughout construction. By optimizing route planning and applying advanced technologies, the project reduced tree felling along the line by more than 83 percent, safeguarding local forest ecosystems.

A delegation from the energy department of Laos' Ministry of Industry and Commerce praised the project's commitment to the principle of "cutting fewer trees and protecting the ecosystem", noting that measures such as high-tower crossings, refined route optimization and drone inspections significantly minimized the project's environmental impact, in line with Laos' goals of promoting clean energy development and ecological conservation.
