1. Jet fuel plant sources should be developed in a manner which is non-competitive with food and where biodiversity impacts are minimized; in addition, the cultivation of those plant sources should not jeopardize drinking water supplies.
2. Total lifecycle greenhouse gas emissions from plant growth, harvesting, processing, and end-use should be significantly reduced compared to those associated with fuels form fossil sources.
3.  ln developing economies, development projects should include provisions for outcomes that improve socioeconomic conditions for small-scale farmers who rely on agriculture to feed them and their families, and that do not require the involuntary displacement of local populations.
4.  High conservation value areas and native eco-systems should not be cleared and converted for jet fuel plant source development.

SAFUG is aiming at developing a world leading fact base on sustainable alternative fuels in order to provide a body of peer-reviewed research and best practices for supporting the practical application of common sustainability criteria for the implementation of sustainable aviation fuels. It intends to support the development of government policies which promote the development, certification, and commercial use of sustainable, lower carbon aviation fuels.
