Green flights are not easily accessible, scientists warn.
Though you might be wishing it, scientists warn that guilt-free flying is still a ways off.
Environmentally friendly jet fuels are a key component of plans for flying that is climate-friendly.
To achieve "jet zero" aviation by 2050, the government must also switch to renewable fuel.
However the Royal Society comes to the conclusion that there is currently no one, definite replacement for conventional fuel.
The industry's trade group for UK airlines declared that the industry was committed to the 2050 goal and that using sustainable fuels will be essential to achieving it.
2.4% of the world's glasshouse gas emissions and 8% of the UK's emissions are brought on by aviation. This gas warms.Green flights are not easily accessible, scientists warn.
Though you might be wishing it, scientists warn that guilt-free flying is still a ways off.
To combat climate change and global warming, plans for climate-friendly aviation rely on a greener atmosphere.
Governments and the aviation sector are experimenting with measures to lessen the climatic implications of conventional kerosene fuel as demand for flights is predicted to rise.
In their report for the Royal Society, the authors considered four alternatives to the 12.3 million tonnes of jet fuel used in the UK each year.
It came to the conclusion that there was no immediate alternative to fossil jet fuel.
Nowadays, a small number of airlines employ biofuel that is primarily manufactured from Green hydrogen cannot yet be produced with enough renewable electricity.
The inability of current plane engines to run on hydrogen-based fuel is another significant impediment.
Ammonia and synthetic fuels are also being considered, but it's not clear if existing aircraft could utilise them as they require even more green hydrogen.
According to the scientists, it is still unknown just how much each alternative fuel might lessen flying's impact on the environment.
However, they emphasise that while an effective alternative fuel will likely be found in the long run, new designs for airports and aeroplanes will be required.
They are urging further study into environmentally friendly aviation fuel, arguing that if the UK invested in finding a solution, it could become a global leader.
A fresh fuel is required.They claim that it must be commercially viable, secure, usable anywhere, and have a high enough energy density to be used on lengthy trips.
The trade group for UK airlines, Airlines UK, said that the industry was committed to the 2050 "jet zero" aim and that renewable fuels were secure and becoming more widespread.
There is no magic solution, but it can be accomplished this decade by modernising airspace to make flying more efficient, introducing new zero emission technology like hydrogen aircraft, and increasing the use of sustainable aviation fuels.
Airlines UK responded to the Royal Society's claim that the UK's insufficient supply of sustainable fuels for the aviation industry would strain the nation's food supply.
