Brits could be flying around the world on planes fuelled by human faeces in the next few years.
Transport Secretary Grant Shapps has revealed plans to force airlines to use 10 per cent eco-friendly jet fuel by 2030.
He also wants to set an ambitious target for 'eco-fuel', by having it rise to 75 per cent by 2050.
This new eco fuel is set to be developed in hopes of providing a less harmful way to travel abroad.
Sustainable aviation fuels can be created from household waste and cooking oils.
It can also be generated from sewage, meaning human waste could be fuelling the future and helping the government reach their green goals.

The progressive plans could save about 23 megatons of carbon by 2050 - which is the equivalent of half a million flights to Brit holiday hotspot Tenerife a year.
In a further boost, it could also generate up to 11,000 green jobs by 2050.
Brits going on their summer holiday will be able to jet off without adding significant harm to the planet.
About a fifth of Britain's dirty carbon emissions is made up from transport, with planes responsible for about 2.5 per cent globally.
Mr Shapps said told The Sun : "Aviation will be central to our future growth and plans to build back greener from the pandemic, which is why we have invested over £20 million in the past year to decarbonise the sector in line with our world-leading net-zero targets.
"With 100 days to go until COP26, we’re ramping up our efforts even further to help companies break ground on trailblazing waste to jet fuel plants and put the UK at the forefront of international Sustainable Aviation Fuel production."
The Department of Transport has also named the eight companies that will receive £15million in government funds to produce the eco-fuel as part of the Green Skies competition.
More than 1,000 jobs across Cheshire, Lincolnshire, Tees Valley and South Wales are expected to be generated in the production of this new eco-fuel.
