In the era of climate change and the global commitment to Net Zero 2050, developing high-speed rail (HSR) is not just about transportation—it is a green infrastructure strategy that reduces emissions, protects the environment, and drives sustainable growth. With the North–South high-speed rail project, Vietnam has a unique opportunity to integrate green solutions right from the planning and construction phases.
Why green infrastructure maters for high-speed rail (HSR)
-
- Lower CO₂ emissions: HSR produces 70–90% fewer emissions compared to aviation and road transport.
- Energy efficiency: Energy consumption per passenger is 5–7 times lower than cars.
- Green urbanization: Supports TOD development, reduces private car dependency, and encourages public transport.
- Lower CO₂ emissions: HSR produces 70–90% fewer emissions compared to aviation and road transport.
Green infrastructure solutions for HSR
