We need a new model for production and consumption. According to World Watch, “If the consumption aspiration of the wealthiest of nations cannot be satiated, the prospects for corralling consumption everywhere before it strips and degrades our planet beyond recognition would appear to be bleak”

Renewable fuels company Sustainable Oils shared the results of a life-cycle analysis of jet fuel created from proprietary Camelina seeds. According to the study, renewable jet-fuel made from Camelina reduces carbon emissions by 84% percent compared to the petroleum-based counterpart.

A team at Michigan Tech University based their research on Camelina grown in Montana and then processed into bio-jet fuel using “UOP hydroprocessing technology”. Next generation biofuels are true hydrocarbons and in the molecular aspect are indistinguishable from fossil fuels, which makes Camelina oil a good candidate to quickly reduce carbon emissions produced by aviation.
