For the first time ever, LanzaTech has produced 1, gallons of jet fuel, derived from waste industrial gases from steel mills, via a fermentation process. The fuel has passed all its initial performance tests with flying colors. Where temperatures rise to more than 2 degrees Celsius above pre-industrial levels. Limiting climate change to below the two degree level is a primary goal of the Paris Climate Change Agreement. In fact, it is the Event which Paris Agreement precisely aims to avoid. Like the event horizon of a black hole, we have no way of exactly knowing what will occur once we pass the two-degree threshold.

A Virgin Atlantic jumbo jet has flown between London's Heathrow and Amsterdam using fuel derived from a mixture of Brazilian babassu nuts and coconuts. Environmentalists have branded the flight a publicity stunt and claim biofuel cultivation is not sustainable. Earlier this month, Airbus tested another alternative fuel - a synthetic mix of gas-to-liquid. Virgin boss Sir Richard Branson said the flight marked a "vital breakthrough" for the entire airline industry.
Qantas works hard to improve its fuel efficiency , and the next logical step in creating a more sustainable industry is to encourage the development of aviation biofuel. Unlike fossil fuels, biofuels can be created sustainably. We've already made Australia's first commercial biofuel flight, and now we're using our landmark Qantas Future Planet research to promote and develop the widespread use of aviation biofuel. Relative to fossil fuels, sustainably produced biofuels result in a reduction in greenhouse gas emissions across their life cycle illustrated in the diagram below. The historic trans-Pacific hour flight operated with approximately 24,kg of blended biofuel, saving 18,kg in carbon emissions.
