We use 3rd party registry systems like ISCC, RSB, 123Carbon and Assure
The Problem:
The aviation industry is still increasing its emissions at an unprecedented rate, projected to triple by 2050.
Our Solution:
Fly less, or choose flights that combine sustainability with your airfare, reducing emissions in the most practical way.
The science behind BookBetter
Every flight's footprint is shaped by four factors:
Distance
Aircraft Efficiency
Fuel Type
Contrails
At BookBetter, we act on every part of this equation to make lower-emission travel possible.
Reduce distance flown
We prioritize train options for short-haul routes, cutting emissions by 90% or more by connecting in places with exceptional rail connectivity.
- Optimized flight paths that minimize unnecessary distance
- Direct routing whenever possible to reduce fuel consumption
Reduce the energy required to fly
We source from airports that prioritize ground operations with renewable energy & low emission ground transport to reduce overall carbon usage.
- Modern, fuel-efficient aircraft
- Renewable energy-powered airport operations
Reduce CO₂e released by type of fuel
We allocate 100% SAF through ISCC SAF registry, abiding most rigorous sustainability requirements.
- Sustainable Aviation Fuel (SAF) reduces lifecycle emissions by up to 80%
- Support for operators committed to net-zero by 2050
Reduce contrails
We adapt flight paths to avoid contrail zones and prioritize direct flights to reduce environmental impact.
- Using direct flight routes avoids high-humidity zones and reduces unnecessary detours.
What is SAF?
Sustainable Aviation Fuel (SAF) is an alternative fuel made from renewable materials like:
- Used cooking oil
- Agricultural residues
- Renewable energy sources such as green hydrogen (known as e-SAF).
Depending on the production method, SAF can reduce aviation emissions by more than 80% compared to fossil kerosene, considering the total life cycle. SAF is currently used in existing aircraft and infrastructure.
Why SAF matters?
2050
The Aviation industry aims net-zero by 2050. (ICAO)
80%
Sustainable Aviation Fuel (SAF) can cut lifecycle emissions by up to 80%. (ICAO)
4%
Aviation is responsible for about 4% of global warming. (ICAO)
Certified fuel, verified impact.
We provide SAF certifications that ensure transparency and accountability across every stage of production.
We source certified waste-based SAF, fully accredited to support new fuel production.
These certifications ensure the origin, production process, and emissions reductions of the fuel, offering full transparency at every step.

Why we focus on flying
When you travel by plane, the vast majority of your trip’s emissions come from the flight itself. That’s why focusing on reducing the impact of your flight is the most important first step.
At BookBetter, we encourage trains or other lower-emission options instead of planes. But when flying is the only practical choice, we help you reduce the overall impact.
