Vietjet leads Southeast Asia in emissions efficiency on intra-regional flights

Vietjet has been recognized as the most emissions-efficient airline for intra-Southeast Asia operations, according to the 2025 Flight Emissions Review by Cirium, a leading global aviation data and analytics provider. This achievement reinforces Vietjet’s position among the region’s most efficient and sustainable airlines.

Key Achievement
- Vietjet has been ranked the most emissions-efficient airline for intra-Southeast Asia flights in the 2025 Flight Emissions Review by Cirium.
- The airline recorded 64.5 grams CO₂ per Available Seat Kilometre (CO₂/ASK), outperforming Singapore Airlines (66.7 g) and Lion Air (67.1 g).

Why It Matters
- CO₂/ASK Metric: Measures emissions relative to passenger capacity, a key benchmark for operational efficiency.
- Fleet Advantage: Vietjet operates one of the youngest fleets in the region, primarily Airbus A320/A321 including NEO variants, which deliver 15–20% fuel savings compared to older models.
- Technology Adoption: Uses platforms like SkyBreathe and SFCO₂ for flight data analytics and fuel optimization.

Industry Context
- Short- and medium-haul routes dominate intra-Southeast Asia, making efficiency harder to achieve. Vietjet’s performance shows strong optimization across aircraft configuration, network planning, and load management.
- The airline was also named among the Top 7 global airlines for sustainability in 2025 by AirlineRatings.

This recognition positions Vietjet as a regional leader in sustainable aviation, reinforcing its brand as both cost-efficient and environmentally responsible.
