"Green" Flights

Taking small steps towards a more sustainable future?
How about taking a flight?
It has now become possible to power an airplane with a 100% bio-fuel.

Instead of using kerosene, the polluting fossil fuel, the plane is fuelled by a rapeseed oil derivative.
There are also multiple possibilities to use algae, flax and even used cooking oil to power the "green" flights.

The reason why these fuels are said to be 'green' is that the plants from which they are derived are absorbing CO2 as they grow, removing it from the atmosphere. when they burn as a fuel they release the CO2 back, but without the net addition.

Currently, aviation is responsible for 2% of greenhouse gas emissions, and considering the future use of the bio-fuels this can be reduced to 0%

The trial flights on the mixture of bio-fuel and normal fuel have been conducted since 2008.
There have been many researches and trials since that time and, fortunately, everything goes well.
And in 2011 the first flight with 100% bio-fuel happened between Amsterdam and Paris.
