Heightened awareness about the climate crisis has forced airlines to rethink their strategies and invest in new ones to reduce their carbon footprint. There's an international push to achieve net-zero air by the year 2050. That's not too far away, and airlines are pushing for game-changing innovations.
Here are a few ways airlines can reduce emissions and positively contribute to the growing concern about climate change.
Sustainable Air Fuels
One change that many airlines are embracing is switching from traditional jet fuel to sustainable air fuel (SAF). From an emissions standpoint, SAF creates the same amount of CO2 when burned. However, the savings come from the manufacturing process.
SAF isn't made with traditional fossil fuels. Instead, it's a product of vegetable and waste oils. The manufacturing process absorbs as much as 100 percent of the CO2 created when burned. The offset is substantial. SAF uses feedstock that doesn't compete with crops or contribute to forest degradation. It's a sustainable alternative that many airlines are already using.
Investing in Fuel-Efficient Aircraft
Airlines are already pushing for better fuel efficiency. But the changes are often minimal compared to what's possible.
Many aviation experts believe vertical take-off and landing (VTOL) aircraft are the future. Private VTOL aircraft are more efficient and produce significantly fewer emissions. The best concepts can accept passenger travel while using hybrid-electric propulsion systems.
With all-electric travel for short hops, these aircraft will produce zero emissions. But even on existing air corridors, they generate less than a quarter of what traditional jets do.
Private VTOL aircraft show great promise, flipping the concept of air travel on its head and providing a more eco-friendly alternative to planes. Furthermore, the lack of airstrip space required to take off opens the doors to creating better, more efficient routes.
Better Route Optimization
Where and how an aircraft flies matters. Several factors impact fuel efficiency, but conditions can change rapidly. Airlines can reduce greenhouse gas emissions by investing in on-demand route optimization technology. Optimization can ensure that every flight produces as few emissions as possible when paired with SAF and other sustainability measures.
